RADIATION ONCOLOGY PRACTICE STANDARDS
Part B: Guidelines
RANZCR ASMIRT ACPSEM CNSA NZCNC
Part B presents guidelines in support of the 16 fundamental standards (Part A) developed
for radiation oncology practices. It should be read in conjunction with the 16 standards.
The Tripartite Committee, formed in 1998, is a peak group in Radiation Oncology representing the three key professions involved in radiation therapy:
• The Royal Australian and New Zealand College of Radiologists (RANZCR), Faculty of Radiation Oncology (FRO),
• Australian Society of Medical Imaging and Radiation Therapy (ASMIRT).
• The Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM). In 2019 the Tripartite Committee was replaced by the Radiation Oncology Alliance with the inclusion of radiation oncology nurses supported by the Cancer Nurses Society of Australia (CNSA). The main objectives of the Alliance are:
• To represent a key forum for collaboration between the radiation therapy professions in the areas of quality, standards, workforce and public interest.
• To act as an important liaison point for the Department of Health, and its committees and working groups.
• To communicate key sector priorities to the Government and to the public.
• To maintain good communication between FRO, ASMIRT, ACPSEM, CNSA. The Royal Australian and New Zealand College of Radiologists, the Faculty of Radiation Oncology, Australian Society of Medical Imaging and Radiation Therapy (formerly, Australian Institute of Radiography) and the Australasian College of Physical Scientists and Engineers in Medicine, received Australian Government funding support for the development and publication of the original Radiation Oncology Practice Standards and Supplementary Guide.

INTRODUCTION 1
BACKGROUND 2
In 2002 the report A Vision for Radiotherapy by Professor Peter Baume [1] identified a number 3
of national safety and quality issues relating to radiation oncology. The Radiation Oncology 4
Jurisdictional Implementation Group (ROJIG) was established to develop a response to the 5
Baume enquiry. In 2003 it produced a report recommending the development of a quality 6
program to be implemented as a priority. The Radiation Oncology Reform Implementation 7
Committee (RORIC) was then established and tasked with the development and 8
implementation of a quality program. The Quality Working Group was set up as a sub-9
committee of RORIC. It identified the need for profession agreed practice standards as a key 10
component of a quality system. 11
12
The main professionals providing radiation therapy treatment are radiation oncologists, 13
radiation therapists and radiation oncology medical physicists. These professions are 14
represented by the following organisations within the Tripartite Committee: 15
• Royal Australian and New Zealand College of Radiologists (RANZCR), Faculty of 16
Radiation Oncology (FRO) 17
• Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) 18
• Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM) 19
In 2019 the Tripartite recognised the contribution of radiation oncology nurses (RON) to patient 20
care and changed the name of the group to the Radiation Oncology Alliance, thereby including 21
RONs as part of the professional groups. Th current review of the Radiation Oncology Practice 22
Standards (ROPS) has provided an opportunity to incorporate the Radiation Oncology Nursing 23
Practice Principles into the ROPS. 24
• The nursing organisations involved are: 25
o Cancer Nurses Society of Australia (CNSA) 26
o New Zealand Cancer Nurses College (NZCNC) 27
28
Nominees from these professional bodies constitute the Alliance. 29
30
The Tripartite Committee—funded by the then Department of Health and Ageing (DoHA) 31
through RANZCR—commenced work to develop radiation oncology practice standards. Draft 32
Standards were developed and reviewed by the Tripartite Committee along with numerous 33
volunteers from the three professions and submitted to DoHA in early 2007. These Standards 34
were edited by members of the professions in consultation with quality standards experts 35
(Tripartite Standards Working Group) under the auspices of the Tripartite Committee. The 36
resultant 16 basic Standards were published in draft form as Radiation Oncology Practice 37
Standards in 2008. DoHA and the professions believed it to be essential to pilot the 38
acceptance of and ability to implement these standards. A number of public and private 39
facilities volunteered to trial them. The National Association of Testing Authorities (NATA) was 40
contracted to assist the facilities with the trial and to provide feedback to the Tripartite 41
Committee and to the Quality Working Group. 42
43
The use of the Radiation Oncology Practice Standards—Part A: Fundamentals is likely to 44

Version 3, 2021
underpin reform in the sector. 45
46
THE CURRENT SITUATION 47
As mentioned above, the 16 Standards were distilled from the original draft standards that 48
were presented to DoHA in 2007. The latter were extremely detailed and expansive and have 49
undergone fine-tuning by members of the editing group with review by the three professions 50
culminating in this document. It is anticipated that radiation oncology facilities, in particular 51
new facilities, will find it a valuable resource supporting the Radiation Oncology Practice 52
Standards—Part A: Fundamentals thereby assisting in the provision of safe and effective 53
radiation therapy to oncology patients. 54 55
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 3
Version 3, 2021
SCOPE 56
57
The Radiation Oncology Practice Standards—Part A: Fundamentals and Part B: Guidelines 58
are considered to be essential to the delivery of safe quality care to radiation oncology 59
patients; as such, both documents should be read together. This document provides additional 60
essential material in support of the Standards and should be used to complement them. The 61
two documents are linked by identical headings and descriptors for each individual standard 62
and criterion. As the Standards are interrelated inevitably there will be some duplication both 63
within and between the two documents. 64
65
The Standards are compliant with the Australian Commission on Safety and Quality in 66
Healthcare National Safety and Quality Health Service Standards.[2] 67

STANDARDS 73
FACILITY MANAGEMENT 74
STANDARD 1—STAFF 75
Staff competence is ensured by recruitment and selection procedures and maintained 76
by staff development and a performance review system. 77
78
CRITERION 1.1 79
There are registers of current registration/licence to practise for all applicable staff. 80
81
SUPPLEMENTARY COMMENTARY 82
All Radiation Oncologists (ROs), Radiation Therapists (RTs), Radiation Oncology Medical 83
Physicists (ROMPs) and Radiation Oncology Nurses (RON) are appropriately qualified and 84
maintain their eligibility to their professional associations and meet requirements of regulatory 85
bodies. 86
87
Staff members who work with ionising radiation or radioactive substances in states with 88
radiation licensing may be required to record induction and continuing radiation safety training. 89
Practitioners in other states are monitored by their state registration board or radiation safety 90
committee. 91
92
A competency is defined as proficiency, ability or a skill set based on a complex range of 93
knowledge, skills and attitudes.[3] Clinical competencies will develop from “learning in 94
context”.[4] 95
96
Advances in radiation oncology technology and its application in clinical practice require on-97
going training and education programs.[5] Training in clinical centres forms a significant 98
component of qualification and professional accreditation as an RO, ROMP and RT. 99
100
ROs achieve Fellowship through training at facilities accredited by the Royal Australian and 101
New Zealand College of Radiologists (RANZCR) and supervised by the RANZCR Radiation 102
Oncology Education and Training Committee.[6] Overseas trained specialists who wish to have 103
their specialist medical qualifications recognised in Australia initially apply to the Australian 104
Medical Council for registration to practise as ROs. Both an assessment of their training and 105
experience and a formal examination conducted under the auspices of the RANZCR are 106
required prior to their eligibility for recognition as a specialist in radiation oncology and for 107
Fellowship of the College.[6] 108
109
RTs must complete either an undergraduate degree or a graduate entry degree from an 110
accredited university. In both streams, radiation therapists are required to meet AHPRA’'s 111
professional capabilities for registration, to ensure they are safe and competent practitioners. 112
Following graduation both groups are then also eligible for recommendation for a 'Statement 113
of Accreditation' from the Australian Society of Medical Imaging and Radiation Therapy 114
(ASMIRT) [7] 115
To practice in Australia under protected titles, Radiation Therapist’s must be registered with 116
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 6
Version 3, 2021
the Medical Radiation Practice Board of Australia under the National Registration and 117
Accreditation Scheme (the National Scheme). Resumption of Professional Practice 118
candidates and overseas graduates with qualifications from institutions with programs that 119
have not been approved by ASMIRT must undertake an Assessment of Qualifications gained 120
outside Australia in Radiation Therapy, to demonstrate skills and knowledge of modern 121
radiation therapy practice including technology applications and treatment techniques. A 122
Statement of Qualification will be granted and a letter for use in the immigration process 123
issued. [8] 124
125
ROMPs are medical physicists who are registered with the Australasian College of Physical 126
Scientists and Engineers in Medicine (ACPSEM) on the ACPSEM Qualified Medical Physics 127
Specialists (QMPS) Register in Radiation Oncology, or who have an equivalent level of 128
training, skills, knowledge and expertise to a person on the register as determined by a 129
relevant authority. To gain registration a medical physicist needs to be awarded certification 130
in radiation oncology by the ACPSEM Radiation Oncology Certification Panel or be 131
determined by the panel that they have achieved an equivalent level of competency. Medical 132
physicists achieve certification through the ACPSEM either by successful completion of 133
ACPSEM Training, Education and Assessment Program (TEAP), or through an assessment 134
of them having completed a program equivalent to the TEAP that may include the requirement 135
for additional training and education to match the TEAP standards. For a medical physicist to 136
maintain their registration with the ACPSEM they are required to abide by the ACPSEM Code 137
of Ethics and to undertake continuous professional development. 138
RONs are registered or enrolled nurses who provide comprehensive, holistic, high-quality 139 radiation oncology nursing care for patients as part of the cancer continuum. RONs are 140 accredited annually through the Australian Health Practitioners Regulation Agency (AHPRA) 141 for Nursing and Midwifery attaining the mandatory registration requirements of the agency and 142 Board. RONs work in a radiation therapy setting, have specialist knowledge and skills related 143 to radiation oncology, and identify as a radiation oncology nurse. Radiation oncology nurses 144 support departmental issues of safety and quality care, and work within the mandatory and 145 legislative requirements of the role. 146
147
CRITERION 1.2 148
Performance review systems supported by staff development programs are in place and 149
current. 150
151
SUPPLEMENTARY COMMENTARY 152
A professional development program at each facility is recommended for all staff. In addition, 153
performance review can have a significant effect on skill development and practice.[9] 154
155
The range of competencies required in radiation therapy treatment can be divided into three 156
areas: clinical expertise, risk management and professional responsibilities. 157
158
The competencies needed by medical specialists include the roles of medical expert, clinical 159
decision maker, communicator, collaborator, health advocate, manager, scholar and 160
professional.[10] 161
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 7
Version 3, 2021
Radiation Therapist’s competencies involve Professional Practice, Communication, Clinical 162
Knowledge and Application, Critical Thinking and Quality Assurance Evaluation, Safe Delivery 163
and Clinical Management, as well as, Lifelong Learning [8]. 164
The ROMP competencies span across all aspects of dosimetry in the areas of radiation 165
therapy equipment commissioning, accuracy, reliability and quality assurance, radiology 166
physics and radiation safety and emerging technologies related to medical physics and 167
biomedical engineering. RON competencies are determined by the local authority and also 168
include clinical decision maker, communicator, collaborator, patient advocate, manager, 169
scholar and professional. 170
171
To support these competencies, participation in education and continuing professional 172
development (CPD) is recommended. Continuing education (CE) is shown to improve 173
theknowledge, skills and behaviour of health professionals as well as enhancing patient health 174
outcomes. CE is most effective when it is ongoing, interactive, and contextually relevant and 175
based on needs assessment.[11] The supervision of staff is enhanced when mentorship is 176
provided by staff with skills and training as an educator.[12]. Interprofessional education relating 177
to common issues is a recognised mode of learning with and from professional colleagues 178
where teamwork and collaboration are important competencies.[13] 179
To reduce adverse clinical incidents, staffing levels and non-clinical time for training and 180
development should be reviewed regularly to take account of the facility’s current workload, 181
research and development activities, maintenance of quality systems and pressures 182
associated with commissioning new equipment or systems.[14] 183
184
Participation in CPD is mandatory for AHPRA registration and/or registration with the New 185
Zealand MRTB. 186
187
The ACPSEM provides a CPD register for its members to facilitate professional responsibilities 188
in maintaining professional standards of practice. 189
190
SUPPLEMENTARY EVIDENCE 191
• Staff members have documented current position descriptions that describe their 192
required skills and knowledge. 193
• Documentation of orientation provided for all new staff. 194
• There is a CPD policy that describes the support for participation in continuing 195
professional development such as in-house programs, mentorship, study leave, 196
conferences and workshops and evidence to prove the CPD policy is being used. 197
• Access to other facilities for training is available where relevant. 198
• Staff members responsible for the education, training and supervision of fellow 199
colleagues have access to further instruction and support. 200

Version 3, 2021
STANDARD 2—WORKFORCE PROFILE 204
The workforce is managed to ensure delivery of safe quality care. 205
206
CRITERION 2.1 207
Staffing numbers are established to safely meet planned patient care capacity. 208
209
SUPPLEMENTARY COMMENTARY 210
The mix of skill and experience within the workforce should be evaluated and managed 211
according to service, safety and quality objectives and facility operation. 212
213
Health care systems that have similar resource levels to Australia provide points of reference 214
for workforce profiles for ROs, RTs and ROMPs.[16-22]. 215
216
Expert clinician narratives acknowledge that best staffing principles for RONs is to 217
assign a nurse to the same patients as an RO under the line management of a nurse 218
Manager, advanced practice nurse and/or nurse educator. Further nursing resources will 219
include specialty resources such as gamma knife, brachytherapy, paediatrics and research, 220
and evening shifts.[23] 221
222
CRITERION 2.2 223
Rosters and schedules incorporate time for non-direct patient care activities applicable to the 224
facility’s service delivery profile. 225
226
SUPPLEMENTARY COMMENTARY 227
Rosters and scheduling should be considered in terms of the availability of skilled and 228
experienced staff. Rostering should facilitate skill development, maintenance and continuing 229
education with the support of management through the provision of financial and non-financial 230
resources. 231
232
SUPPLEMENTARY EVIDENCE 233
• There is a protocol that describes the process and frequency for workforce evaluation 234
and management activities consistent with the recommendations of the respective 235
professional bodies. 236
• Data are collected and monitored to support workforce planning. 237
• Records of financial and non-financial support provided to allow staff to participate in 238
non-direct patient care activities. 239
• There are policies to facilitate recruitment and retention of skilled staff and evidence to 240
show the success of the policies. 241
• There is a system for managing the availability of staff, whether directly employed by the 242
facility or providing services under contractual arrangements. 243
• Rosters show protected non-patient care time is available to assist all staff to undertake 244
continuing education. 245

Version 3, 2021
STANDARD 3—MANAGEMENT OF RADIATION ONCOLOGY PATIENT RECORDS 248
Management of the radiation oncology patient record supports safe, quality care. 249
250
CRITERION 3.1 251
The radiation oncology patient record is the primary, comprehensive source of information for 252
the delivery of patient care within the radiation therapy department and complies with 253
jurisdictional legislation. 254
255
SUPPLEMENTARY COMMENTARY 256
Records, administrative and recording practices are structured to provide a relevant, accurate 257
and retrievable description of the patient’s progress through their treatment. Records may be 258
a composite of paper and electronic systems. Information relevant to patient care from other 259
sources should be available to staff within the department - ideally by incorporating into the 260
patient record. 261
262
The precise detail, timing and location of any previous and current radiation treatment, 263
including site, technique, verification procedures, delivered dose and number of fractions 264
should be obtained and clearly recorded in the individual patient health record. 265
266
Staff responsible for radiation treatment of an individual patient should be identified in the 267
radiation treatment record. 268
269
CRITERION 3.2 270
The radiation oncology patient record and databases containing patient information are 271
logged, secure, accessible by authorised personnel only and are retained according to 272
jurisdictional requirements. 273
274
SUPPLEMENTARY COMMENTARY 275
The individual patient health record should be structured to allow sufficient access to 276
necessary information by all health professionals involved in providing care. 277
278
Data have a role as a clinical and legal record and as a planning tool. Information relating to 279
a patient’s treatment is important for evaluating outcomes and can affect future treatment for 280
that patient. 281
282
Records should be stored securely and the data retrievable through explicit privacy and 283
confidentiality procedures. 284
285
Record-keepers in possession or control of a record that contains personal information must 286
ensure that it is protected by security safeguards against theft, loss, unauthorised access, use, 287
modifications or disclosures, and against other misuse. 288
289
Facilities should plan and design systems such that the duration of storage complies with 290
jurisdictional requirements. The ability to retrieve electronic information at a later date will 291
require additional planning in relation to upgrade and obsolescence of any electronic systems. 292
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 10
Version 3, 2021
293
SUPPLEMENTARY EVIDENCE 294
• The patient ID is recorded on each page of the treatment chart, whether paper or 295
electronic format. 296
• Specific treatment related data are recorded at each treatment session, including the 297
identity of at least two (2) accredited persons delivering treatment. 298
• There is a policy defining the levels of physical and electronic restriction of access to 299
facility records. 300
• There are documented procedures for storage of electronic information when systems 301
are upgraded or changed. (Examples include the ability to access information from 302
previous electronic systems, and the existence of a DICOM archive for radiation therapy 303
images, plans and dose distributions.) 304
• Tenders relating to the upgrade or replacement of system components that hold 305
electronic data include specifications for comprehensive data migration to ensure that 306
previous data is still accessible. 307
308
309

RO Practice Standards Working Group Page 11
Version 3, 2021
STANDARD 4—DATA MANAGEMENT 310
The management of data supports clinical activities and reporting requirements. 311
312
CRITERION 4.1 313
The management of clinical data is planned, systematic and supports clinical audit, clinical 314
trials, outcomes analysis and existing cancer registry requirements. 315
316
SUPPLEMENTARY COMMENTARY 317
Data items and definitions should be based on national data dictionaries to facilitate 318
comparisons of outcomes, choices and treatment. There is agreement in principle between 319
Australian jurisdictions to adopt a nationwide core clinical data set and dictionary.[22] In any 320
radiation oncology facility, the data to be collected will need to consider the requirements of a 321
national data set as well as those of other reporting bodies. For example, professional bodies 322
and statutory authorities require monitoring and audit of specific aspects of radiation therapy 323
practice for quality assurance activities. 324
325
In each facility and jurisdiction there is a wide variety of stakeholders with differing data 326
requirements. These may include clinicians, administrators and research groups and it is 327
useful to consult these groups when planning or reviewing data collection.[22,23] 328
329
Strategic planning for data collection should include a multidisciplinary data management 330
team led by an appointed data custodian. Understanding user needs is imperative to maintain 331
the relevance and accuracy of data and ongoing support for its collection.[25,26] Periodic audit 332
of databases helps to ensure data integrity and improve patient management and organisation 333
planning. Reporting the outcomes of data audits can improve staff communication, 334
professional satisfaction and confidence in data collection activities. Any resulting 335
improvements in data quality and integrity are then likely to contribute to improved 336
management of cancer patients.[14,25] 337
338
CRITERION 4.2 339
Disease/diagnosis and staging data conform to recognised classification systems in 340
accordance with facility policies. 341
342
SUPPLEMENTARY COMMENTARY 343
Data collections within radiation oncology facilities are used for the assessment of care of 344
patients, health policy development, clinical research, clinical improvement and health service 345
provision so it is important that the data are accurate and current.[25-28] 346
347
Accurate reporting of cancer incidence, cancer management, facility activities and treatment 348
outcomes are dependent on reliable and comprehensive data.[25,28,30] Accordingly, data 349
collection processes need to consider the reliability of data sources and timeliness of data 350
entry.[33-35] 351
352
The accuracy of data collection and data transcription depends on appropriate training for staff 353
in current data collection practices and recognised classification systems. 354
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 12
Version 3, 2021
355
CRITERION 4.3 356
There is a facility-agreed minimum data set used for each patient that meets the facility’s 357
clinical decision making and reporting responsibilities. 358
359
SUPPLEMENTARY COMMENTARY 360
Epidemiological research relies upon verifiable source data.[28] 361
362
Data collected should be sufficient to allow care delivery to be tracked, monitored and 363
evaluated. Provision of training in data entry, adequate staffing levels and resources are 364
important to achieve compliance.[25,28,30] 365
366
Monitoring demographic trends in cancer incidence, clinical practice trends and clinical 367
outcomes may assist in forward planning for resources, facilities and infrastructure. 368
369
SUPPLEMENTARY EVIDENCE 370
• Toxicity detail provided by clinicians is consistent with the definitions specified in the 371
National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events 372
(CTCAE v5.0) or a recognised equivalent. 373
• There is an appointed data custodian who has responsibility for the control and security 374
of data collection and accuracy of entry. 375
• The data management plan should address: 376
o consistency and continuity between electronic and paper records; 377
o accountabilities; 378
o data collection; 379
o data storage needs of the organisation at all levels; 380
o timeliness of data entry; 381
o date stamping of events; and 382
o management of events that are not date-stamped. 383
• The data management plan should include guidelines for ROs, RTs and ROMPs and 384
RONs about the format of data provision and entry. 385
• There are scheduled reviews of the needs of staff for data resources, particularly with 386
respect to identifying deficits, the use of available resources and prioritising strategies for 387
improvement. 388
• There is a policy relating to facility response to data requests from professional and 389
statutory bodies for identified clinical indicators. 390
391
392
Radiation Oncology Practice Standards Part B: Guidelines

Version 3, 2021
STANDARD 5—FACILITY INFRASTRUCTURE 393
The facility infrastructure promotes safe quality care and accountability in the delivery 394
of radiation treatment services. 395
396
CRITERION 5.1 397
The strategic planning process addresses the operational and physical organisation of the 398
facility and takes account of changing needs. 399
400
SUPPLEMENTARY COMMENTARY 401
A rational estimate of the number of megavoltage treatment units required is dependent on a 402
number of factors. These include: the proportion of patients with given cancer type with 403
indication for radiation therapy treatment; the incidence of these cancer types; radiation re-404
treatment rates; and the machine throughput in terms of number of treatment courses per year 405
for a linear accelerator. 406
407
Long term planning and investment is needed; to train the highly specialised staff required to 408
prescribe, plan and deliver radiation therapy, provide treatment units and equipment and build 409
the facilities for them.[31] 410
411
The facility’s strategic plan should consider: 412
• the patient pathway; 413
• communication and information systems; 414
• measurement, quality assurance (QA) and quality improvement (QI) programs and 415
process control systems; 416
• waste management; 417
• emergency and disaster management; 418
• security and safety management; 419
• risk, incident and complaints management; 420
• Work Health and Safety (WHS); 421
• processes for addressing codes of ethics, conduct; 422
• processes for strategic alignment with local environmental needs, state and national 423
directives, benchmarks or guidelines; 424
• processes for assessing, evaluating, and adapting to emergent technologies and 425
techniques; and 426
• resources, financial, accounting, governance, and asset processes.[32] 427
428
The process of strategic planning should also identify when, where and how to provide allied 429
health services, as access to these services and care is essential to the delivery of quality 430
radiation therapy services.[33] 431
432
Staff involvement is crucial to organisational success. A participative culture involving all 433
stakeholders, including patients and consumers will encourage individuals to work together in 434
adapting and meeting new challenges, reshaping work patterns and redesigning job roles.[34] 435

CRITERION 5.2 438
Facility management and performance are based on a multidisciplinary approach to ensure 439
accountability and safety in the delivery of radiation treatment services. 440
441
SUPPLEMENTARY COMMENTARY 442
Operational infrastructure design addresses: resources, reward systems, physical work 443
environment and job design; staff training and development; staff well-being; processes for 444
monitoring and managing change; and processes for ensuring alignment with the overall 445
strategic design.[32] 446
447
The most important component in safe practice is qualified personnel. The safe and efficient 448
operation of each item of equipment requires equipment system specific training.[35] 449
450
Radiation therapy requires a multidisciplinary approach to the justification, adoption and 451
implementation of new processes, technologies and techniques, as changes in the operational 452
design and performance in one area may increase or decrease workloads in others. 453
454
Clearly defined leadership and organisational arrangements help ensure radiation therapy 455
services are of a high quality.[27] 456
457
CRITERION 5.3 458
The physical infrastructure and environment including patient, staff and public amenities are 459
designed, managed and maintained to support safe practice in the delivery of radiation 460
therapy. 461
462
SUPPLEMENTARY COMMENTARY 463
The physical infrastructure and environment of facilities must reflect their strategic objectives 464
and operational infrastructure. These are important safety and quality considerations in facility 465
design. 466
467
The facility should employ staff or contracted services with appropriate qualifications in room 468
design, shielding and radiation safety. 469
470
The functional performance specifications for all equipment need to meet local requirements 471
and relevant standards, and any deviations identified, documented and justified.[35-38] 472
473
Life-cycle management includes upgrade and replacement planning, failure contingency 474
planning, repairs, modifications, maintenance and calibration programs, service and 475
operations logbook systems.[39] Adherence to manufacturer’s specifications for life-span limits 476
on equipment and systems will also ensure patient and staff safety and continuity of service. 477
478
The facility should comply with radiation protection legislation, including shielding 479
requirements and equipment. When designing radiation shielding for a treatment room, factors 480
that need to be considered include: workload of the equipment and the way it will be used; 481
and the intended use and occupancy of adjacent rooms. 482
483
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 15
Version 3, 2021
When purchasing new or replacement equipment, radiation protection requirements for 484
shielding design, interlocks, control rooms etc should be considered. All differences should be 485
identified, and any additional works specified by qualified expert(s), and included in the 486
equipment purchase process. These would include changes in external beam energy; for 487
example, by replacement of cobalt unit with linear accelerator of higher beam energy, requiring 488
additional bunker shielding; installation of HDR unit and required control area and interlock 489
systems. 490
491
The IAEA [40] stipulates the requirements for dedicated ‘hot laboratories’ for the use of unsealed 492
sources. This includes the provisions for storage, shielding fume cupboards and support 493
services. 494
495
The IAEA [40] states that any modifications to building design subsequent to initial approval will 496
be subject to a new approval process. 497
498
The IAEA [40] states that relevant areas in the facility should be classified as controlled or 499
supervised when specific protection measures and safety procedures are needed to control 500
normal exposure and to prevent potential exposure. 501
502
SUPPLEMENTARY EVIDENCE 503
• The facility, its services and amenities are easily located, suitably signposted and have 504
access for the disabled. 505
• Annual workloads and equipment performance, including comparisons to published and 506
local benchmarks, are measured, monitored and documented. 507

STANDARD 6—FACILITY PROCESS MANAGEMENT 519
The provision of radiation therapy treatment services is timely, coordinated and 520
equitable to ensure optimal patient outcomes. 521
522
CRITERION 6.1 523
The patient pathway is co-ordinated to provide optimal patient outcomes within available 524
resources. 525
526
SUPPLEMENTARY COMMENTARY 527
A patient’s progress through a care facility is often referred to as the patient pathway. Fully 528
understanding this pathway by mapping the processes is a key element for organising patient 529
flow; ensuring that diagnosis, referral, treatment planning, treatment delivery, supplementary 530
care and review are as efficient and patient-friendly as possible. 531
532
Other factors may impact on facility process management, for example staffing and equipment 533
resources. Monitoring and benchmarking suitable indicators will highlight issues that need 534
addressing. 535
536
CRITERION 6.2 537
Care is provided in a timely manner according to patient need. 538
539
SUPPLEMENTARY COMMENTARY 540
Waiting time is one indicator of quality of care. It is defined as “the time elapsed between the 541
radiation oncologist’s decision that treatment should commence (ready for care) to the first 542
treatment being delivered”. That decision is influenced by post-operative healing phase, post-543
chemotherapy recovery phase, patient requested delay, time for treatment of intercurrent 544
morbidities that make the patient unfit to start treatment and any other delay beyond the control 545
of the facility. These delays should be separately recorded.[41,42] 546
547
Clinical need and resource availability affect waiting list management. Undue delay, treatment 548
interruption and unplanned treatment prolongation may result in adverse clinical outcomes 549
and/or patient harm, reduction in patient satisfaction, negative impact on relatives and carers, 550
negative impact on staff morale and increased demand for labour resources. 551
552
The Board of the Faculty of Clinical Oncology[43] list the five major causes of unscheduled 553
interruptions to radical radiation therapy: 554
• machine and staff availability; 555
• public holidays/statutory days; 556
• patient transport problems; 557
• medical problems; and 558
• social circumstances that lead to a patient’s failure to attend for treatment as scheduled. 559
560
Measures to address delay, treatment interruption or prolongation include: 561
• adjusted working hours (but this practice is not recommended as a long-term solution);[42] 562
• provision and maintenance of adequate resources; 563
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 17
Version 3, 2021
• avoidance of the adverse effects of prolonged breaks over public holidays by appropriate 564
treatment scheduling; 565
• planned scheduling of machine downtime to avoid treatment interruptions; and 566
• compensation measures, including: 567
o twice daily fractionation, minimum six-hour interval; 568
o weekend treatment; 569
o use of biologically equivalent dose in fewer fractions to achieve planned overall 570
time, where risks of normal tissue complication allow; and 571
o additional fractions where compensation cannot be achieved within the original 572
planned time.[44] 573
574
Benchmarking through the regular monitoring of equipment capacity helps identify future 575
planning and resource needs.[42,45] 576
577
SUPPLEMENTARY EVIDENCE 578
• There is a written protocol that describes the principles of the patient pathway. 579
• Minutes and records from multidisciplinary team meetings that address the patient 580
pathway and facility needs. 581
• There is a protocol for prioritising patients based on clinical need. 582
• Data on process indicators are provided to authorised organisations on request to allow 583
benchmarking against other facilities. 584
• Audits of compliance with patient pathway policies and protocols. 585
• There is a policy for the transfer of patients to other facilities when treatment is extended, 586
machine downtime or when patients cannot be accommodated in the facility. 587
• There are reporting mechanisms adhering to nationally agreed standards enabling 588
comparisons of waiting times. 589

Radiation therapy equipment performs to specifications that ensure accurate and safe 593
clinical treatment. 594
595
CRITERION 7.1 596
Qualified, trained and experienced staff specify requirements of new radiation therapy 597
equipment. 598
599
SUPPLEMENTARY COMMENTARY 600
All radiation therapy equipment including software supports the clinical application, safety and 601
accuracy of treatment planning and delivery. 602
603
The acquisition of new radiation therapy equipment should follow a needs analysis with input 604
from a multidisciplinary team. 605
606
Compliance to relevant Australian and New Zealand Standards encompasses environmental 607
conditions, protection against abnormal operation and fault conditions including electric shock 608
hazards and mechanical hazards, as well as protection against hazards from unwanted or 609
excessive radiation, and the accuracy of operating data. 610
611
It is the responsibility of the manufacturer to provide all relevant documentation for equipment 612
function and maintenance. 613
614
CRITERION 7.2 615
New radiation therapy equipment, and any modification to same, is installed, acceptance 616
tested and commissioned for clinical use by qualified personnel. To ensure accurate and safe 617
clinical usage, any newly commissioned equipment requires independent dosimetry 618
intercomparison. 619
620
SUPPLEMENTARY COMMENTARY 621
The equipment commissioning and QA records constitute the primary sources of information 622
to support the accuracy and safety of radiation delivery. 623
624
It is essential that installation of equipment—or modification to existing equipment—is 625
performed only by suitably trained staff. Before modifications are made to existing equipment, 626
staff should consult the manufacturer to establish if the planned modifications will affect 627
performance of the equipment. 628
629
Acceptance testing is done to ensure that equipment performs to the specifications agreed in 630
the purchase contract. Qualified staff should perform acceptance testing in conjunction with 631
the manufacturer or their agent. Where particular local needs have been identified in the 632
purchasing process, these should be tested with reference to the specified requirements. The 633
warranty period commences when the equipment is accepted. 634
635
Data obtained during acceptance testing provides the information on which to base decision 636
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 19
Version 3, 2021
about the life-cycle of the equipment. 637
638
Equipment commissioning can be divided into three phases—verification of adherence to 639
specifications, data acquisition and beam modelling. The baseline information obtained during 640
this process provides the foundation for the future QA program. 641
642
It is essential to include software in all QA considerations. All changes to software should be 643
subject to stringent acceptance, commissioning and QA checks as for initial commissioning. 644
645
Software changes from manufacturers may be mandatory, to fix a known problem, or may be 646
elective; for example, to acquire increased functionality. In advance of proposed changes, 647
release notes should be obtained from the manufacturers and the scope of the changes and 648
implications for clinical use discussed with them. 649
650
Any software change should be scheduled to minimise disruption to clinical treatments, and 651
to allow sufficient time for checking and QA before release for clinical use. Some checking 652
programs are extensive, such as treatment planning system upgrades to the software. 653
654
All staff using software should be trained. 655
656
If any of the specifications are not met, it is essential the vendor, all affected staff and the 657
regulatory authority (where applicable) be notified. 658
659
CRITERION 7.3 660
There is a preventative maintenance program for radiation therapy equipment that ensures 661
safety, reliability, reproducibility and accuracy. 662
663
SUPPLEMENTARY COMMENTARY 664
The functional performance of radiation therapy equipment may be affected by breakdown, 665
ageing or deterioration of any component. The output, laser checks and isocentre of the 666
treatment machine need to be verified daily. 667
668
Maintenance may be carried out by the manufacturer’s representative, or by in-house staff 669
who are trained and qualified. 670
671
CRITERION 7.4 672
There is a quality assurance (QA) program to assess the ongoing performance of all radiation 673
therapy equipment used in treatment planning and delivery. 674
675
SUPPLEMENTARY COMMENTARY 676
Equipment commissioning and QA records provide evidence that all radiation therapy devices, 677
both software and hardware, are maintained and monitored to ensure that the accuracy of 678
dose delivery and imaging meets national and international standards. These provide the 679
basis of an audit trail. 680
681
QA procedures may involve all members of the multidisciplinary team, depending on the 682
Radiation Oncology Practice Standards Part B: Guidelines

Version 3, 2021
equipment. These processes may be managed by a QA committee and should be approached 683
from an organisational viewpoint and not be patient specific. 684
685
ROMPs are responsible for withdrawal of or restrictions to clinical use of equipment, when 686
performance does not comply with stated baselines and tolerances or is not fit for clinical 687
purpose as determined by the multidisciplinary team.[45] After any upgrade or modification of 688
equipment by the manufacturer, the ROMP is responsible for ensuring appropriate checks are 689
performed [46] and QA procedures put in place. 690
691
All staff performing equipment QA procedures must be trained and be familiar with local 692
practices. The QA committee is responsible for local guidelines on the introduction of new 693
equipment or techniques. 694
695
The QA program should have planned periodic reviews—and should also be reviewed 696
consequent to the publication of new or revised national or international guidelines—to ensure 697
that it continues to cover all aspects of treatment techniques in use. 698
699

TREATMENT PLANNING AND DELIVERY 723
STANDARD 8—THE RADIATION THERAPY TREATMENT PRESCRIPTION 724
The radiation therapy treatment prescription documents the intended course of 725
treatment for the individual patient. 726
727
CRITERION 8.1 728
Patients are informed of the benefits and risks of the proposed radiation therapy treatment 729
and their consent is documented by the consenting clinician. 730
731
SUPPLEMENTARY COMMENTARY 732
Informed decision-making is an important component of high quality health care. 733
Patients are entitled to make their own decisions about whether to undergo proposed radiation 734
therapy treatment and need information to make these decisions.[47] The information should 735
be provided in a format and manner that helps patients understand their diagnosis and the 736
proposed radiation treatment. Patient involvement in the development of written information 737
makes it more relevant, easier to read and more understandable, without increasing their 738
anxiety.[53] It needs to be appropriate to the patient’s circumstances, personality, expectations, 739
fears, beliefs, values and cultural background.[49] 740
741
Written information is a source of information that complements the information provided 742
verbally by the consulting radiation oncologist. Written information should be offered to 743
patients rather than expecting them to find it.[39] This should include information that is 744
anatomical-site specific and information about radiation therapy treatment issues in general, 745
including the use of permanent skin marks. 746
747
Information should describe the potential side effects for each individual patient. Advice for 748
dealing with and managing side effects should also be included and there should be an 749
identified point of contact for patient queries. 750
751
Written information for patients should be evidence based and reviewed regularly to ensure it 752
remains current.[50] 753
754
It is important to tailor written information to the local population, which includes providing it in 755
the major languages spoken within the area. 756
757
CRITERION 8.2 758
The radiation therapy treatment prescription conforms to legislation, licensing regulations, 759
policies and clinical protocols and guidelines. 760
761
SUPPLEMENTARY COMMENTARY 762
The radiation therapy treatment prescription is the primary source of information for the 763
planning and delivery of safe radiation therapy treatment and documents the intended course 764
of treatment. 765

Version 3, 2021
therapy treatment prescription by the radiation oncologist. The use of consistent and common 768
datasets and terminology known by all staff enables the prescribed treatment to be accurately 769
interpreted. 770
771
The use of prescription templates is common practice in Australia. Templates may be pre-772
printed prescription sheets or in electronic form. Their use enables all prescriptions for 773
radiation treatment within a facility to conform to a common format and provide consistent 774
information. 775
776
National and international disease-related protocols and treatment guidelines are useful 777
evidence-based tools that contribute to consistency in the prescribing of treatment. 778
779
Reports from the International Commission on Radiation Units and Measurements [56-61] 780
provide recommendations for the prescribing, recording, and reporting of radiation therapy 781
treatment. Use of these internationally recognised guidelines allows comparison between 782
facilities, and is often mandated in clinical trials. 783
784
CRITERION 8.3 785
Radiation therapy treatment prescriptions are regularly audited by peer review. 786
787
SUPPLEMENTARY COMMENTARY 788
There is evidence that ongoing audits of treatment contribute to the continuing quality 789
improvement of radiation therapy practice and staff education.[4,9] 790
791
SUPPLEMENTARY EVIDENCE 792
• The staff education program includes the principles of informed consent and their 793
application. 794
• There is a procedure for involvement of professional interpreter services. 795
• Evidence-based written information, including the potential side effects, is available to 796
patients about anatomical-site specific treatment and radiation therapy treatment issues. 797
• Information for patients is written in the main languages spoken in the local population 798
and contains contact details for patient queries. 799
• Written information for patients is regularly reviewed and includes input from patients. 800
• There is a policy that states the requirements and definitions to be used for prescribing 801
radiation therapy treatment. 802
• Nationally and internationally endorsed disease-related protocols for the prescription of 803
radiation therapy treatment are available. 804
• There is a documented policy for the conduct of radiation therapy treatment prescription 805
audits that describes: 806
o the frequency of audits; 807

STANDARD 9—PLANNING PROCEDURES 813
Comprehensive, safe and consistent planning procedures promote optimal treatment 814
outcomes. 815
816
CRITERION 9.1 817
Treatment planning protocols are documented, accessible to staff and endorse evidence-818
based best practice. If there is no clinical protocol available for the procedure/treatment, as far 819
as possible, the procedure/treatment should follow the best available protocol. 820
821
SUPPLEMENTARY COMMENTARY 822
Uniformity of treatment planning protocols is desirable so as to enable evaluation of treatment 823
outcome. Regular auditing of treatment planning protocols is an important quality assurance 824
initiative.[62,63] 825
826
Treatment planning protocols encompass: patient positioning, immobilisation and monitoring, 827
simulation and imaging, contouring and target definition, suggested beam positioning, plan 828
development and evaluation. 829
830
The contouring procedure, which encompasses the treatment voluming process, delineates 831
all relevant regions of interest including, external contour, gross tumour volume (GTV) or 832
clinical target volume (CTV) or planning target volume (PTV), organs at risk (OAR), air cavities, 833
bolus, artifacts and fiducial markers, using manual and/or computer-assisted methods. [55, 57, 834 56, 59] Uniformity can be improved by adopting standardised nomeclatue. 835
836
Quantitative data displays encompassing dose statistics, dose volume histograms and 837
biological modelling—tumour control probability (TCP) and normal tissue complication 838
probability (NTCP)—can be utilised to obtain quantitative information about an isodose 839
distribution.[60,61] 840
841
Checking the record of radiation therapy treatment—including the developed, evaluated and 842
approved isodose plan—before a patient commences treatment, minimises the risk of 843
planning-induced treatment errors.[62] 844
845
Treatment planning system software requires a comprehensive quality control procedure to 846
ensure that the plan development and evaluation are accurate.[37,59,63-66] 847
848
CRITERION 9.2 849
External and internal immobilisation methods and equipment are fit for purpose. 850
851
SUPPLEMENTARY COMMENTARY 852
A comfortable, stable and reproducible patient position is essential for the delivery of 853
consistent and accurate radiation therapy and can be achieved using an immobilisation 854
device/method.[37,59, 63-70] 855
856
All staff who use immobilisation devices should have relevant technical knowledge, and be 857
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 24
Version 3, 2021
aware of the usefulness, limitation/s and application of each immobilisation device. 858
859
All immobilisation devices should undergo a risk assessment and comprehensive clinical 860
evaluation—including the effect on dose delivery—so that both patient safety and treatment 861
outcomes are not compromised.[47, 68,71-73] 862
863
To determine the most appropriate immobilisation device for each patient and promote optimal 864
treatment outcomes it is essential to consider the principles of stability and reproducibility, 865
comfort, individual needs, organ motion and the complexity of the proposed radiation therapy 866
technique.[74-78] 867
868
The optimal treatment position is achieved and reproducibility errors are minimised by 869
comprehensive documentation that itemises patient immobilisation and set-up details.[62,79-81] 870
871
Every personalised immobilisation device should be labelled to avoid incorrect use.[6] It is 872
important to check that the correct device is used for each patient and there is visual 873
verification by a second person. 874
875
It is necessary that all patients requiring an internal immobilisation method are given adequate 876
instructions to maximise stability and reproducibility of patient position, as well as ensuring 877
patient safety.[74] 878
879
Where external immobilisation devices restrain patients, it is essential to have an action plan 880
for rapid release to minimise patient distress.[63] 881
882
Access to mould room facilities is required for the manufacture of custom immobilisation 883
devices and additional treatment requirements 884
Any immobilisation devices that are reused at a later date on another patient must have clear 885
infection control measures in place. 886
887
Other items that may be used every day on the same patient must have specific cleaning, 888
storing and infection control measures in place. 889
890
CRITERION 9.3 891
Planning and imaging procedures localise, delineate and define target volumes and organs at 892
risk, as well as enabling treatment verification. 893
894
SUPPLEMENTARY COMMENTARY 895
The pre-simulation process is important to promote accuracy and efficiency.[59,68] Timely 896
information for patients helps reduce anxiety, increases willingness to comply with treatment, 897
and promotes reproducibility of patient position.[69,70,82] 898
899
Patient position and immobilisation is determined at simulation. The simulation procedure 900
combines the planning imaging process with the technical and clinical planning process. 901
902
Ensuring patient privacy, dignity and comfort is essential at all times. 903
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 25
Version 3, 2021
904
Implementing an infection control policy minimises the harm that can arise from the 905
transmission of health care associated infections, thereby ensuring patient and staff safety, 906
and improving quality of care.[83,84] 907
908
Virtual simulation permits the radiation oncologist and radiation therapist to access a 909
computed tomography (CT) data set to define a volume, treatment field and the isocentre. 910
911
Pre-treatment verification allows the radiation oncologist and radiation therapist to evaluate 912
the feasibility of a proposed treatment plan, acquire verification images or re-evaluate a 913
previously defined treatment field.[68] 914
915
Planning and imaging equipment should be compatible with other equipment used in the 916
facility to enable accurate and timely communication of digital images. 917
918
The dose a patient receives while undergoing planning and imaging procedures should be ‘as 919
low as reasonably achievable’ (ALARA) to promote patient safety. 920
921
Comprehensive and accurate labelling of all planning images ensures image data can be used 922
for quality improvement, education and research activities, and also as an important quality 923
assurance procedure to minimise reproducibility errors and avoid incorrect use.[41,62,89] 924
925
All planning images and planning data need to be durable, confidential, stored securely and 926
easily accessible. 927

STANDARD 10—DOSIMETRY 973
A dosimetry system, consistent with national and/or international standards, ensures 974
the safety and accuracy of the prescribed radiation dose for all clinical treatments. 975
976
CRITERION 10.1 977
Dose measurement ensures compliance of the dose delivery with the treatment prescription. 978
979
SUPPLEMENTARY COMMENTARY 980
Accurate dosimetry can only be attained by strictly following a specific protocol that defines 981
the method and appropriate correction factors to determine absorbed does at the reference 982
point (formalism). In Australia dosimetry formalism is determined by the Australasian College 983
of Physical Scientists and Engineers in Medicine (ACPSEM).[67] 984
985
ROMPs are responsible for the calibration of dosimetry equipment and must ensure that it is 986
fit for the purpose of accurately measuring dose. 987
988
CRITERION 10.2 989
The calibration of the radiation dose delivered by all clinical treatment units is consistent with 990
dosimetry codes of practice recommended by national regulatory authorities. 991
992
SUPPLEMENTARY COMMENTARY 993
Accuracy in the dose delivery of treatment equipment is verified through periodic independent 994
dosimetry audit.[86] 995
996
Treatment delivery equipment must be calibrated using dosimetry equipment with calibrations 997
traceable to the national dose standard kept by a national standards laboratory. [59,63,87] 998
999
CRITERION 10.3 1000
A system for the calculation of dose distributions in the patient ensures that all doses can be 1001
directly related to the absolute dose determined for the treatment equipment under reference 1002
conditions. 1003
1004
SUPPLEMENTARY COMMENTARY 1005
The purpose of the treatment planning data must be identified, as well as the date of issue, 1006
document name and number. The data must have clear guidance for its use and its limitations 1007
specified.[37,67,86] 1008
1009
For purpose of audit, the data sources must be traceable with details of measurement 1010
conditions.[86,87] Inaugural data collection at new treatment units should be verified with 1011
relevant published reference data as endorsed by the ACPSEM.[67] 1012
1013
For purposes of ongoing quality assurance, all dosimetry data should be saved as reference 1014
data in a suitable format [67] and all superseded data must be withdrawn from clinical use to 1015
prevent accidental use of outdated data. 1016
1017

Version 3, 2021
CRITERION 10.4 1018
Calculation of monitor units (MU), exposure times or dwell times required to deliver each 1019
prescribed dose are independently checked. 1020
1021
SUPPLEMENTARY COMMENTARY 1022
Treatment planning systems (TPS) and independent dose calculations systems should be 1023
commissioned according to international best practice and national ACPSEM 1024
recommendations.[67,85,88] 1025
1026
All calculations of dose to a patient must be independently checked by a second authorised 1027
RT or ROMP before treatment is delivered. This check should be performed using an 1028
independent dosimetry system to verify the calculation process and that the appropriate 1029
dosimetry data have been applied. Software or processes to perform the monitor unit check 1030
calculation should be independent of the primary calculation; for example, software and 1031
machine data files should not be shared in the calculations. 1032
1033
If there are changes to the treatment plan or monitor units, any new calculated dosimetric 1034
data, including monitor units are to be subject to the same calculation and checking processes 1035
as the initial calculation process. 1036
1037
To verify the entire dose calculation chain, the dosimetry for any new treatment delivery 1038
equipment, TPS (including changes to algorithms) and new treatment technique should be 1039
verified by a ROMP by dose measurement in a phantom before clinical implementation.[67,89,90] 1040
1041
CRITERION 10.5 1042
There is a system for independent verification of dose delivery to individual patients. 1043
1044
SUPPLEMENTARY COMMENTARY 1045
In-vivo dosimetry should be used to verify new methods of dose calculations, including new 1046
treatment planning systems; new treatment techniques or modalities, when new beam 1047
modifiers are introduced; and to assess dose to critical organs or structures.[89-91] 1048
1049
The ROMP is responsible for establishing and maintaining the accuracy of in-vivo dosimeters 1050
according to ACPSEM recommendations and/or international recommendations, where 1051
appropriate. 1052
1053
In-vivo dosimeters may perturb the incident radiation beam, which means that the effect of the 1054
in-vivo dosimeter on the dose distribution should be assessed by a ROMP and approved by 1055
the prescribing RO. 1056
1057
CRITERION 10.6 1058
For SBRT/SRS treatments where CTV to PTV margins are a small and geometric accuracy is 1059 critically important, a system shall be in place to ensure that the required geometric accuracy 1060 is routinely achievable. 1061 1062
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 29
Version 3, 2021
SUPPLEMENTARY COMMENTARY 1063
Typically an end-to-end test with the capability to test the geometrical accuracy of the entire 1064 treatment chain combined with an audit of patient immobilisation would satisfy this 1065 requirement. The Australian Clinical Dosimetry Service includes a suitable end-to-end test in 1066 their stereotactic level III audits. 1067 1068
SUPPLEMENTARY EVIDENCE 1069
• There is documentation that dosimetry equipment is checked at least at the frequency 1070
recommended by the ACPSEM. 1071
• Documentation of actions taken to re-calibrate equipment following independent and 1072
internal audit processes. 1073
• Documented systems for control of all data used in patient dose calculations are 1074
available. 1075
• There are documented pre-defined or set action levels to determine if independent dose 1076
calculations are outside tolerance limits. 1077
• There is access to in-vivo dosimetry equipment for patient dose monitoring. 1078
• The procedure for in-vivo dosimetry is based on national and international 1079
recommendations. 1080
• Patient in-vivo dosimetry records or reports are available as part of the medical record of 1081
treatment. 1082
• There is documentation to demonstrate that the geometrical integrity of the treatment 1083
chain in check in its entirety at least annually, and individual components more 1084
frequently.[92] 1085

STANDARD 11—RADIATION THERAPY TREATMENT DELIVERY 1088
Treatment is delivered correctly, accurately, safely and consistently with due 1089
consideration of the patient’s rights and responsibilities. 1090
1091
CRITERION 11.1 1092
Verification procedures are used that minimise the risk of incorrect patient, incorrect dose and 1093
anatomical treatment misplacement. 1094
1095
SUPPLEMENTARY COMMENTARY 1096
It is important to treat a patient with the correct treatment to the correct site otherwise a 1097
misadministration occurs. The National Safety and Quality Health Service Standards, 1098
standard 5 (Patient Identification, A) requires “At least three approved patient identifiers are 1099
used when providing care, therapy or services”.[2] 1100
1101
The site to be treated should be verified daily with the patient. This may be done by: asking 1102
the patient to state the site (including laterality) to be treated; using a photograph of the 1103
treatment site or field marks; or using an anatomical diagram displaying the location of 1104
treatment fields. 1105
1106
Patient confidentiality should be protected in the identification process. 1107
1108
Accredited or credentialed persons delivering the first treatment should use more than one 1109
source of information to crosscheck data in the electronic record and verify (RV) system; for 1110
example, treatment plan, patient’s health record, set-up, and isocentre heights. Regular 1111
checks of the RV system should be undertaken to monitor the integrity of these data. 1112
1113
Any changes to treatment should be recorded in the patient’s treatment chart or electronic 1114
record with the identification of the person making the change and the recorded date of the 1115
changes. 1116
1117
A position verification process is used to monitor patient positional differences and 1118
uncertainties and facilitate accurate treatment delivery through the adoption of appropriate 1119
action levels and clearly specified interventions. The frequency of verification images depends 1120
on the site treated, treatment intent, the immobilisation device used, an individual patient’s 1121
condition and the intended degree of reproducibility sought. 1122
1123
Checks of the source/focus to surface distance (SSD/FSD) before the first treatment and at 1124
regular intervals verify that the patient geometry is as expected in the treatment plan. They 1125
also detect changes in patient shape over time; for example, due to weight loss. Day to day 1126
variations in patient set up are likely to be random and smaller in magnitude than first day 1127
variations. Other influences in positioning accuracy include disease change and modification 1128
to set up or shielding. 1129
1130
Verification of the treatment isocentre and field position is done prior to the first treatment and 1131
re-evaluated at regular intervals during the course of treatment. This may be done by 1132
Radiation Oncology Practice Standards Part B: Guidelines

Version 3, 2021
comparing it to the digitally reconstructed radiograph (DRR), CBCT or other localisation 1133
methods such as fiducial markers. 1134
1135
Orthovoltage, superficial x-ray and electron treatments should have the field position verified 1136
visually at the treatment unit at the time of each treatment to decrease the incidence of field 1137
placement errors. 1138
1139
CRITERION 11.2 1140
Patients are observed during radiation delivery and monitored according to need. 1141
1142
SUPPLEMENTARY COMMENTARY 1143
A visual monitoring system is essential for patient safety. In instances where patients may 1144
require assistance, or in an emergency; for example, if a patient vomits, treatment can be 1145
suspended immediately. 1146
1147
CRITERION 11.3 1148
Patients are reviewed for their fitness to continue and for their psychosocial needs throughout 1149
a course of treatment. 1150
Nursing Practice Principle 2: The information and education needs of patients and their 1151 carers are identified and met. Refer to Appendix A. 1152 1153
SUPPLEMENTARY COMMENTARY 1154
Weekly review should include documentation of any radiation-induced side effects (preferably 1155
using a recognised acute toxicity scale) with documention of any interventions provided or 1156
recommended. All interventions suggested or introduced must be followed up to determine 1157
effectiveness. 1158
1159
Progress reviews allow the patient’s psychosocial wellbeing to be monitored and any issues 1160
managed in an appropriate and timely manner. 1161
1162
Patients should be given the opportunity to discuss any relevant issues with staff throughout 1163
their treatment course. 1164
1165
Nursing Practice Principle 4: Healthcare professionals are skilled in identifying the 1166
potential effects of radiation therapy and the impact of treatment on patients. Refer to 1167

Facility governance acknowledges and supports safe practice, quality improvement, 1201
innovation and the safe and considered introduction of new technologies. 1202
1203
SUPPLEMENTARY COMMENTARY 1204
Risk management proactively reduces identified risk to an acceptable level with preventative 1205
measures rather than reactive remedies. It plays a vital role in supporting and informing 1206
decision-making in providing a safe and secure environment for patients, staff and the 1207
public.[96] 1208
1209
CRITERION 12.2 1210
Risk to patients, staff and the public is managed in accordance with the relevant WH&S 1211
legislation for the respective jurisdiction, national standards and the principles of safe practice. 1212
1213
SUPPLEMENTARY COMMENTARY 1214
Risk Management and the Guidelines for Managing Risk in the Healthcare Sector (AS/NZS 1215
4360: 2004) describe a coordinated approach to clinical risk management. Two Australian 1216
bodies provide direction on safe working practices and environments. 1217
1218
Safe Work Australia requires that facilities provide a safe environment for all employees in 1219
compliance with relevant workplace safety directives. It also requires each facility to have an 1220
incident notification, investigation and reporting system for all staff and patient incidents that 1221
complies with workplace safety directives. In addition, all staff should be trained in manual 1222
handling procedures relevant to their daily duties.[94] 1223
1224
The National Occupational Health and Safety Commission require all facilities to meet all 1225
building regulations contained in the Occupational Health and Safety Act. It also requires each 1226
facility to ensure that all chemical use and chemical storage meets relevant Occupational 1227
Health and Safety Acts. Risk assessments on all equipment and chemical use should be 1228
undertaken and reviewed on an annual basis. 1229
1230
Similar information is available from the New Zealand Department of Labour. 1231
1232
Good cleaning practices help to reduce infection hazards and have a direct influence on the 1233
quality of care. The cleanliness of the facility should be maintained and monitored. 1234
1235
CRITERION 12.3 1236
Facility governance, policies and procedures incorporate the intent of The Australian Charter 1237
of Healthcare Rights or the Code of Health and Disability Services Consumers' Rights in New 1238
Zealand. 1239
Radiation Oncology Practice Standards Part B: Guidelines

Version 3, 2021
1240
SUPPLEMENTARY COMMENTARY 1241
There are procedures to address patients’ rights and needs. 1242
1243
Feedback on patient satisfaction is regularly obtained, analysed, reported and responded to. 1244
‘Complaint’ handling procedures should be readily available to any individual about whom a 1245
participating organisation holds personal information. The facility is required to promote this 1246
process and ensure that it is easy to use and free of charge.[2] 1247
1248
There are ten underlying principles in the Australian Privacy Act (1988): collection, use and 1249
disclosure, data quality, data security, openness, access and correction, identifiers, 1250
anonymity, trans-border data flows and sensitive information.[95] 1251
1252
The Australian Privacy Act (1988) and the Australian Freedom of Information Act (1982) 1253
outline processes for sharing of relevant patient information between health professionals.[96,97] 1254
1255
CRITERION 12.4 1256
The technical quality of care and patient outcome is evaluated, compared to benchmarks for 1257
best practice, and acted upon accordingly. 1258
1259
SUPPLEMENTARY COMMENTARY 1260
Quality audit entails systematic and independent evaluation of the quality system or its 1261
components to assess performance and to identify areas that need updating or improvement. 1262
A quality audit documents current practice, and can lead to improved service delivery.[6,98] 1263
1264
Chart rounds or clinical audits provide a useful forum for in-house peer review, education and 1265
effective real-time communication among all members of the multidisciplinary team 1266
responsible for delivering radiation therapy treatment.[99] It is paramount to good patient care 1267
for this communication to be clear, precise and accurate in detail. A regular chart audit should 1268
be a part of the quality assurance program of every radiation oncology facility.[100] 1269
Nursing Practice Principle 6: Patients and their carers have the opportunity to participate in 1270 all aspects of care. Refer to Appendix A. 1271 1272

STANDARD 13—RADIATION SAFETY 1309
All radiation exposures are managed to minimise risk to patients, staff and the public. 1310
1311
CRITERION 13.1 1312
The management plan for radiation safety defines responsibilities and delegations of all 1313
persons involved with radiation exposures and management of radiation safety. 1314
1315
SUPPLEMENTARY COMMENTARY 1316
The responsible person has the overall management responsibility and control of the 1317
radioactive source, radiation-producing equipment or medical practice. It may be a natural 1318
person, a corporation, chief executive officer or director of medical services for example.[99] 1319
1320
Each facility that uses radiation is legally required to appoint a natural person as a radiation 1321
safety officer (RSO) to manage radiation safety. In radiation oncology facilities that person will 1322
generally be a senior physicist. 1323
1324
The radiation safety management plan must comply with jurisdictional legislative 1325
requirements. Sufficient resources are needed to support its practical application. The plan 1326
needs to address areas relevant to radiation safety (current IAEA BSS standards): 1327
• work practices for managing medical exposures including the management of pregnant 1328
patients; 1329
• roles and responsibilities in the facility, including reporting and delegation; 1330
• staff training and resource allocation; 1331
• protection and monitoring of staff, patients and areas accessible by the public, quality 1332
assurance procedures and records for all equipment used in the treatment delivery 1333
pathway; 1334
• incident and accident reporting; 1335
• maintenance of records as required by regulatory authority, for workers, radiation 1336
sources and apparatus, and premises; and 1337
• emergency procedures. 1338
1339
The multidisciplinary radiation safety committee should monitor compliance with legislative 1340
requirements, and make recommendations to the facility. 1341
1342
The main duty holders under safety regulations for radiation oncology facilities must be 1343
qualified and one or more must be closely involved in every radiation therapy practice or 1344
procedure.[47] As the radiation therapy treatment prescription provides the justification for the 1345
exposure of the patient, the radiation oncologist maintains responsibility for overall radiation 1346
protection of the patient (IAEA BSS). 1347
1348
CRITERION 13.2 1349
The radiation oncology facility maintains a register of equipment, staff and safety notifications 1350
relating to radiation safety and ensures notification and communication as required by the 1351
regulatory authority. 1352
1353
Radiation Oncology Practice Standards Part B: Guidelines

Version 3, 2021
SUPPLEMENTARY COMMENTARY 1354
The information required on radiation equipment includes treatment room location, beam 1355
energy and modality. Radiation source information required includes the source type, its 1356
strength and location. The location of radioactive sources should be easy to access by all 1357
emergency staff, including fire fighters and police. 1358
1359
Licences are required to acquire, transport and dispose of sealed and unsealed sources for 1360
diagnostic and therapeutic use. The RSO must ensure that there is safe storage accessible 1361
only by qualified staff and that, sources are handled only by qualified staff. Safety procedures 1362
will include: measures to prevent theft, damage and unauthorised use or disposal; processes 1363
to ensure radioactive sources are under control at all times; procedures to ensure that 1364
receivers possess valid authorisation; and periodic inventory. 1365
1366
Legislation in each jurisdiction specifies the acceptable dose limits around premises and in 1367
controlled areas. The RSO must ensure there is compliance with these dose limits and that 1368
interlocks and warning signals are as specified by the legislation. 1369
1370
The Code of Practice states that the responsible person has accountability for the movement, 1371
management and safe discharge of brachytherapy patients. Furthermore, the responsible 1372
person must minimise the risk of contamination from accidental spill or the loss of sources, 1373
and ensure the safe movement and removal of radioactive sources. 1374
1375
In the event of a patient death while undergoing treatment with radioactive substances, 1376
whether sealed or unsealed, and if the deceased still retains, in or on the body, significant 1377
amounts of radioactivity the RSO must detail administrative procedures and instruct all 1378
persons who have a risk of exposure to the deceased. 1379
1380
CRITERION 13.3 1381
Appropriate equipment and resources are available for radiation survey measurement in both 1382
routine checks and emergency situations. 1383
1384
SUPPLEMENTARY COMMENTARY 1385
Radiation oncology facilities must protect the health and safety of staff from the harmful effects 1386
of radiation by personal monitoring, protective equipment and training. 1387
1388
All staff with access to controlled areas, including administrative, nursing and cleaning staff, 1389
need personal monitoring devices.[97] Records of personal monitoring must be regularly 1390
checked by the RSO or delegate. Unusual doses, including doses in excess of the norm but 1391
not necessarily in excess of prescribed limits, need to be investigated and, if necessary, 1392
remedial action taken. Staff must be advised of their radiation assessment results. 1393
1394
Defence-in-depth principles are applied to procedures and processes involving radiation. 1395
These refer to the use of sufficient layers of physical or procedural measures in the facility 1396
design and operating procedures to prevent accidents, minimise harm from error and restore 1397
safety should an accident occur.[97] 1398

Version 3, 2021
Equipment for monitoring radiation and for use in responding to emergency situations includes 1400
a calibrated survey meter that is traceable to a national standard, electronic personal 1401
dosimeters, spill kit, source handing devices, and protective clothing. In the selection of 1402
equipment available and used for the measurement of radiation dose or radioactive 1403
contamination, there should be surplus equipment, which ensures backup. 1404
1405
The radiation safety committee should ensure that people in a facility know their role and the 1406
procedures to be followed in the event of a radiation accident or unplanned exposure. Specific 1407
equipment is required to assess the scope of a radiation emergency or accident and it is the 1408
legal responsibility of the facility to ensure these resources are available. The RSO must 1409
ensure its availability and current calibrations. In the event of an emergency the RSO must 1410
ensure that a system is in place to contact the appropriate staff qualified to deal with the 1411
emergency. 1412
1413
CRITERION 13.4 1414
There is regular review of all radiation safety procedures and physical verification to confirm 1415
continuing radiation safety. 1416
1417
SUPPLEMENTARY COMMENTARY 1418
The radiation management plan should include a review of any changes in techniques and 1419
equipment for radiation safety; identify and address any failures and shortcomings; and 1420
maintain the cooperation of all staff, who should be consulted and informed about radiation 1421
safety management. 1422
1423
SUPPLEMENTARY EVIDENCE 1424
• Working conditions in respect to occupational exposure to radiation are adapted for 1425
female workers who notify their employer should they become pregnant. 1426
• There are protocols, conforming to respective state, national and international 1427
regulations, for the handling and management of brachytherapy and unsealed sources. 1428
• There are protocols based on defence-in-depth principles for radiation emergency 1429
situations that include communication with all qualified staff. 1430
• Records of the calibration of all radiation survey measurement devices are maintained. 1431

Version 3, 2021
STANDARD 14—INCIDENT MONITORING PROGRAM 1434
Participation in incident monitoring programs provides confidence that radiation is 1435
safely delivered in a radiation oncology facility with a safety-conscious culture 1436
focused on learning and prevention of error. 1437
1438
CRITERION 14.1 1439
The radiation oncology facility participates in an incident monitoring program. 1440
1441
SUPPLEMENTARY COMMENTARY 1442
Governance ensures accountability of clinical performance and the delivery of safe treatment. 1443
1444
All incidents and adverse events that occur within the facility must be recorded. Not all will be 1445
directly related to the physical delivery of radiation therapy. The RSO must ensure immediate 1446
internal reporting of any radiation incident or unplanned exposure, including assessments of 1447
significance, results of investigation and any corrective action taken. 1448
1449
Incident reporting mechanisms such as root cause analysis, micro systems analysis and 1450
failure mode and effects analysis are methods of documenting and analysing errors and may 1451
be used to audit risk management interventions. A register of all incidents and errors occurring 1452
in a radiation oncology practice is an essential part of a quality program.[7] 1453
1454
Documentation and records of clinical data should be detailed enough to enable reconstruction 1455
of events in the future.[37,60,99,103,106] 1456
1457
An open disclosure policy is supported by management. The staff members are trained in 1458
open disclosure processes. 1459
1460
SUPPLEMENTARY EVIDENCE 1461
• There is a non-punitive reporting system that encourages feedback on safety issues that 1462
includes clinical performance. 1463
• In the event of unintended dose being delivered there are copies of reports to the 1464
relevant authority and any subsequent advice received from the authority. 1465
• There is evidence of open disclosure practice. 1466
• There is a process that enables the sharing of information on lessons learned from 1467
adverse events with other parts of the health system and other facilities. 1468

Version 3, 2021
STANDARD 15—DOSIMETRIC INTERCOMPARISON 1470
Regular participation in dosimetric intercomparisions ensures confidence that 1471
radiation dose is accurately delivered in a radiation oncology facility. 1472
1473
CRITERION 15.1 1474
The radiation oncology facility participates in ongoing dosimetric intercomparisons of at least 1475
one photon beam and one electron beam every two (2) years, and on commissioning any new 1476
equipment. 1477
1478
CRITERION 15.2 1479
Intercomparisons include at least one level III dosimetric intercomparison every four (4) years 1480
using a treatment scenario relevant for the particular centre. 1481
1482
SUPPLEMENTARY COMMENTARY 1483
The IAEA recommends that all teletherapy equipment outputs are compared at least once 1484
every two years in a regional, national or international program for independent dose 1485
verification.[45] Dosimetric intercomparison is necessary to independently verify the 1486
performance of the radiation equipment and should ideally be performed by an independent 1487
centre. Examples for this are the Radiological Physics Centre in Houston 1488
(http://rpc.mdanderson.org/RPC/home.htm) or the EQUAL network in Europe (EQUAL via 1489
http://www.estro.be/) and now the Australian Clinical Dosimetry Service (ACDS). 1490
1491
Three different levels of complexity are defined for dosimetric intercomparisons:[105] 1492
• Level I: This constitutes an independent check of beam calibration under reference 1493
conditions in a physical phantom, usually water. It typically consists of only one 1494
measurement point. Such services are offered; for example, by the ACDS, Radiological 1495
Physics Center (Houston) and the IAEA. 1496
• Level II: A level II intercomparison verifies not only the dose under reference conditions 1497
but also the accuracy of some other factors required for treatment planning. As electron 1498
dosimetry intrinsically requires a verification of depth dose to determine the appropriate 1499
point of measurement and the electron energy, electron intercomparisons are necessarily 1500
a level II dosimetric exercise.[106] The measurements in level II dosimetric intercomparisons 1501
are done in a physical phantom, however, this may include inhomogeneities and/or surface 1502
contour changes.[107] 1503
• Level III: A level III intercomparison requires the use of an anthropomorphic phantom 1504
which is planned and treated as similar to a patient as possible. This can be a full 1505
anthropomorphic phantom[108] or a semi-anatomical phantom.[109-111] 1506
1507
The advantage of a level III dosimetric intercomparison is that the entire treatment chain from 1508
the acquisition of diagnostic images to the treatment set-up and delivery can be verified. The 1509
disadvantage of verifying many steps in one procedure is that it is often difficult to identify 1510
which step has contributed to a particular outcome. As such it is required to repeat 1511
measurements and check smaller segments of the treatment chain if the overall level III check 1512
identifies a problem. 1513
1514
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 41
Version 3, 2021
A level III dosimetric intercomparison also records the influences of differences in treatment 1515
technique and equipment available in participating centres. 1516
1517
Intercomparisons are also useful to verify other aspects of the radiation therapy delivery. 1518
Examples are brachytherapy [112] and electron irradiation.[106] 1519
1520
Participation in clinical trials requires rigorous quality assurance. Dosimetric intercomparisons 1521
constitute an important part of the process ensuring that treatment in all centres participating 1522
in a multicentre trial is performed in a similar way. 1523
1524
Dosimetric intercomparisons reduce the risk of a serious error. Many of the incidences 1525
reported in IAEA safety report series 17[89] could have been prevented if regular dosimetric 1526
intercomparisons were performed. 1527
1528
Participation in dosimetric intercomparisons itself improves performance—centres who have 1529
previously participated in an external dosimetric audit are less likely to be outside of an 1530
accepted limit on further dosimetric audits than centres that never participated in an 1531
intercomparisons.[113] 1532
1533
SUPPLEMENTARY EVIDENCE 1534
• The radiation oncology facility also participates in dosimetric intercomparisons of at 1535 least one kilovoltage (kV) beam every two years. 1536
1537

Version 3, 2021
STANDARD 16 — CLINICAL TRIALS AND EVIDENCE BASED PRACTICE 1538
Any participation in human clinical trials is supported by governance and 1539
infrastructure to ensure quality care oversight. 1540
1541
Evidence based practice ensures the integration of the best current evidence with 1542
clinical expertise to provide optimal care to each patient. 1543
1544
CRITERION 16.1 1545
Participation in clinical trials conforms to international guidelines of good clinical practice. 1546
1547
SUPPLEMENTARY COMMENTARY 1548
Optimal models of cancer care describe improvements in quality that occur through 1549
participation in clinical trials, based on better outcomes for trial participants and changes in 1550
culture that arise from clinical research. These include changes in attitude to reviewing the 1551
evidence base of treatment, compliance with protocols, and an improvement in evidence-1552
based practice. 1553
1554
Clinical trials are research investigations in which people volunteer to test new treatments, 1555
interventions or tests as a means to prevent, detect, treat or manage various diseases or 1556
medical conditions.[114] 1557
1558
The World Health Organization (WHO) definition for a clinical trial is 1559
‘any research study that prospectively assigns human participants or groups of humans to 1560 one or more health-related interventions to evaluate the effects on health outcomes’. 1561
In Australia, all research involving humans must comply with the principles set out in the 1562 following guidelines: 1563
• National Statement on Ethical Conduct in Human Research (2007) — updated 1564 2018 (National Health and Medical Research Council)(link is external) 1565
• Australian Code for the Responsible Conduct of Research (link is external) 1566 (developed jointly by the National Health and Medical Research Council, the 1567 Australian Research Council and Universities Australia) 1568
• Applicable State and Territory guidelines. 1569 1570
Clinical trials of medicines and medical devices also must comply with: 1571
• ICH Guideline for Good Clinical Practice (link is external) - (Therapeutic Goods 1572 Administration) 1573 1574
Clinical trials of medical devices must also comply with: 1575
• ISO 14155:2020 Medical devices (link is external) - Clinical investigation of medical 1576 devices for human subjects: Good clinical practice (ISO) 1577
1578
The infrastructure required for participation in clinical trials is dependent on factors related to 1579
the individual trial. This means that the indicators used by most multi-centre trials groups relate 1580
to accrual, and data completeness and accuracy (see figure 1 and table 1 below). 1581
1582
Radiation Oncology Practice Standards Part B: Guidelines

Version 3, 2021
Figure 1 [115,116] 1583
• Knowledge and experience of conducting and managing patients in a clinical trial. 1584 • Adequate funding and infrastructure support for clinical trials activity, particularly with the 1585
appointment of a local data manager/clinical trial coordinator, file storage space, and technology 1586 requirements. 1587
• Systems in place to ensure staff work to appropriate guidelines and standards. 1588 • Systems in place to provide training, education and development. 1589 • Ability to work within ethical and legal framework, such as International Committee on 1590
Harmonisation, Good Clinical Practice, Therapeutic Goods Administration. 1591

A multidisciplinary model of care is believed to provide the best outcomes and participation by 1595
the following groups should be considered: ROs, ROMPs, RTs, physicians, surgeons, 1596
radiologists, pathologists, pharmacists, nurses, data managers and clinical trial coordinators. 1597
1598
If the trial necessitates advanced, complex planning or treatment radiation techniques, a 1599
higher level of QA is required when compared to a trial incorporating standard radiotherapy.[115] 1600
1601
As part of research governance, centres should have a research review meeting as a quality 1602
process to review the operational aspects of research, including infrastructure, feasibility, 1603
accrual, protocol compliance, and other technical issues; for example, dosimetric aspects of 1604
compliance. 1605
1606
The Code of Practice for Exposure of Humans to Ionizing Radiation for Research Purposes 1607
requires all research involving the use of ionising radiation conducted in facilities shall be in 1608
accordance with legislation as described in the Radiation Protection Series No. 8.[118] 1609
1610
16.2 EVIDENCE BASED PRACTICE 1611
All clinical services are provided using evidence based or best practice principles. 1612
Commentary 16.2 1613
Evidence based practice underpins the provision of safe, quality care in all aspects of 1614 radiation oncology. 1615
Evidence-based clinical practice guidelines and recommendations are designed to assist 1616 decision making and guide best practice in the management of cancer. 1617
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 44
Version 3, 2021
These guidelines are based on the best evidence available at the time of publication and are 1618 a guide to appropriate practice, to be followed subject to the clinician’s judgement and the 1619 person’s preference in each individual case. 1620
As new evidence becomes available, existing resources may be updated or topic-specific 1621 updates may be developed to act as supplements to existing documents. [119,120] 1622
As per the Australian Commission On Safety And Quality In Health Care action 1.27[2]: 1623
The health service organisation has processes that: 1624
a. Provide clinicians with ready access to best-practice guidelines, integrated care 1625 pathways, clinical pathways and decision support tools relevant to their clinical 1626 practice 1627
b. Support clinicians to use the best available evidence, including relevant clinical care 1628 standards developed by the Australian Commission on Safety and Quality in Health 1629 Care 1630
Good clinical governance promotes clinical practice that is effective and evidence based. 1631 Provides clinicians with ready access to best-practice guidelines, integrated care pathways, 1632 clinical pathways, decision support tools, and the clinical care standards.[2,116,121] Radiation 1633 Oncology departments that, due to size and restricted resources, cannot develop their own 1634 practice guidelines are encouraged to identify and endorse clinical guidelines and pathways 1635 appropriate to their service. 1636
Radiation oncology services can contribute to the generation and promotion of evidence based 1637 practice through peer reviewed research, presentations and publications of locally run 1638 research activities within the accepted ethical rules and hierarchies of evidence. 1639
1640 SUPPLEMENTARY EVIDENCE 1641
• Ethics approval of all clinical trials from a committee in accordance with NHMRC or 1642
Health and Disability Ethics Committee (HEDC) guidelines. 1643
• The governance of clinical trial research is consistent with national and international 1644
standards, in particular those related to informed patient consent. 1645

Version 3, 2021
DEFINITIONS 1659
1660 Acceptance testing The process of verifying that equipment (both hardware and
software) operates to performance specifications agreed between the vendor and customer according to a mutually agreed acceptance protocol.
Accuracy Closeness of the agreement between the result of a measurement and a true value of the measurand (International vocabulary of basic and general terms in Metrology (VIM) draft 2004 revision, definition 3.5). If the true value cannot be determined, then an accepted value may be used as a substitute.
Brachytherapy Radiation treatment using radioactive material (mostly an encapsulated source) brought into close contact with the treatment area (often by surgical means).
Bolus Material (typically equivalent in density to normal tissue) placed directly on the patient in order to alter the dose distribution within the patient.
Commissioning The process of acquiring all the data from a piece of equipment that is required to make it clinically useable in a specific department. Therefore, the commissioning procedure will depend on clinical requirements in a particular centre and other equipment available. For radiation delivery devices commissioning can be divided into three phases: • data acquisition • beam modelling • verification.
Contouring A procedure that involves outlining regions and anatomical structures of interest including, but not limited to external patient contour, GTV/CTV/PTV, OAR, air cavities, bolus, artefacts and fiducial markers—using manual and/or computer-assisted methods.
Dosimetry The measurement of absorbed dose in matter resulting from exposure to ionising radiations. In the context of the standards ‘Dosimetry’ refers to the measurement of physical dose and the provision of these dose measurements for the purpose of treatment planning. Dosimetry can be classified as relative or absolute dosimetry.
Equipment In the context of the standards, the term equipment applies to all hardware and software used in a radiation therapy department.
Facility A real entity that provides radiation therapy services. Facility infrastructure
The framework of the amenities, both physical and operational, that support an organisational unit’s operation and function. This basic architecture and its ‘fit’ with the environment determine how well the unit functions and how adaptive it is to change and future requirements.
Incident An error, a near miss or any adverse event relating to patient care or patient, visitor and staff safety.
Intensity modulated radiation therapy
This term is used to describe the attempt to optimise the dose distribution during external beam radiation therapy delivery. Each radiation field is divided into small segments with varying radiation intensity which allows for target shape, location and the geometry of overlaying tissues. IMRT fields are typically designed using computer driven (or aided) optimisation. This is often referred to as ‘inverse treatment planning’.
Radiation Oncology Practice Standards Part B: Guidelines
RO Practice Standards Working Group Page 46
Version 3, 2021
Interlock A device which can inhibit radiation from commencing or terminate an irradiation process when a certain condition occurs (e.g. someone entering the treatment room).
In-vivo dosimetry The measurement of absorbed dose to the patient at the time of treatment. The measured dose is compared with the planned dose to verify dose delivery. Doses are commonly measured with small detectors which will not affect the therapeutic dose distribution. These detectors may be diodes, thermoluminescent dosimeters (TLDs) or similar devices.
Isocentre A point at the intersection of the rotational axes of gantry, collimator and treatment couch.
Monitor units A MU corresponds to a known amount of charge collected on the internal ion chamber of a linear accelerator. The ion chamber can be calibrated so that the number of MUs relates to the absorbed dose of radiation delivered to the reference point under reference conditions. A MU is a measure of linear accelerator output. Commonly, linear accelerators are calibrated for a specific energy such that 100 MU gives an absorbed dose of 1 Gy under reference conditions.
Multileaf collimator A device that is mounted in the collimator or replaces one of the collimator pairs. It consists of movable leaves which can be positioned freely to allow conformal shielding of organs at risk.
Organisation The legal entity to which a radiation oncology service is affiliated. Operational infrastructure
The management and business systems, structure and processes of the unit, the unit’s services and staff.
Patient pathway A patient’s progress through a facility. Phantom In radiation therapy, the term ‘phantom’ is used to describe a
material and structure which models the radiation absorption and scattering properties of human tissues of interest.
Quality assurance All the planned and systematic activities implemented within the quality system, and demonstrated as needed, to provide adequate confidence that an entity will fulfill requirements for quality.
Quality care Care based on commonly accepted best practice and the associated patient outcomes.
Quality control The techniques and methods built into an organisation’s operations to control individual processes.
Quality improvement Actions taken to review and enhance the quality of a process and/or service.
Quality program Encompasses all quality activities as listed. Radiation oncology medical physicist
A person who is qualified in medical physics to perform the necessary dosimetric calculations, measurements and monitoring in radiation oncology. A suitable person will: (a) be on the Qualified Medical Physics Specialists (QMPS) Register in Radiation Oncology held by the Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM); or (b) have an equivalent level of training, skills, knowledge and expertise to a person listed on the ACPSEM Qualified Medical Physics Specialists (QMPS) Register in Radiation Oncology as determined by a relevant authority.
Radiation oncologist A person who is registered as a medical practitioner by the relevant Medical Board and is a fellow of the RANZCR or equivalent and is licensed to prescribe radiation therapy.
Radiation oncology patient record
The primary source of information and includes the treatment chart (prescription and treatment sheet; paper based or electronic), all

Version 3, 2021
dosimetry and calculation data, as well as localisation and position verification data and images.
Radiation oncology service
The sum total of all affiliated radiation oncology facilities.
Radiation therapist A person who is qualified to standards set by the ASMIRT or registered to practise according to jurisdictional requirements.
Radiation therapy equipment
For the purposes of the standards such equipment is defined as all hardware and software relevant to:
• patient imaging whether radiation emitting or not;
• the planning and calculation of radiation dose to a patient;
• the delivery of radiation treatment to a patient; and
• monitoring, measuring and/or otherwise controlling radiation dose.
Radiation safety officer
A suitably qualified and experienced person who oversees all activities involving ionising radiation in a workplace. As such, the RSO is also responsible for training of others. Consequently, some of the duties may be delegated. The role and responsibilities of an RSO are defined by national standards.
Ready for care Is when the patient is ready to commence radiation treatment as agreed between the patient and the radiation oncologist. Patients are not considered to be ready for care if:
• the radiation oncologist considers treatment should not commence because the patient is in a postoperative healing phase and/or a post chemotherapy phase;
• any existing morbidities require prior therapy; or
• a delay is requested by the patient. Responsible person The person who has the overall management responsibility and
control of the radioactive source, radiation-producing equipment or medical practice. It may be a natural person, a corporation, chief executive officer or director of medical services for example [104]
Service See radiation oncology service. Suitably qualified Means registered (for regulated professions) or eligible for
registration on the ACPSEM Register of Qualified Medical Physics Specialists (for medical physicists), and licensed (where required) to practice according to relevant jurisdictional legislation and the defined scope of practice for that profession; and within any organisationally defined credentialing requirements applicable to specific aspects of practice.
Technical quality of care
Refers to the delivery of correct dose to the correct patient to the correct anatomical site as prescribed.
Treatment planning system
The computer hardware and software (including dose calculation algorithms) used to develop, evaluate and display a radiation treatment plan.
Treatment verification
The process of imaging and evaluating the position of the treatment isocentre, radiation treatment field and/or its shape, or anatomical volume against that determined in the treatment planning process.
Verification Sometimes referred to as Record and Verify or R&V, commonly refers to the matching of a simulated or planned treatment parameter with that set on the treatment unit for treatment delivery.
Waiting time The interval between the ready for care date and first radiation treatment being delivered.
