Products used for any/all stages in
reprocessing (i.e., cleaning, disinfection,
sterilization) must be approved by the
committee responsible for product
selection, by an individual with
reprocessing expertise and by an
individual with infection prevention and
control expertise. (39)
13
![Page 14: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/14.jpg)
The process and products used for
cleaning, disinfection and/or
sterilization of medical
equipment/devices must be
compatible with the
equipment/devices.(42)
14
![Page 15: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/15.jpg)
Occupational Health and Safety for the
healthcare setting will review all protocols for
reprocessing medical equipment/devices to
eliminate or minimize the risk of exposure of
hcws.(19)
Appropriate personal protective equipment
(PPE) should be worn for all reprocessing
activities.(21)
15
![Page 16: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/16.jpg)

Hepatitis B. (22)
Prevent and manage injuries from sharp
objects.(23)
Immediate response to worker exposure
to blood and body fluids. (24)16
![Page 17: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/17.jpg)
Preventive maintenance program for
pasteurizing equipment must be
implemented and documented.(36)
17
![Page 18: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/18.jpg)
Reprocessing medical
equipment/devices require review
by an individual with infection
prevention and control expertise. (9)
18
![Page 19: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/19.jpg)
Audits of the cleaning process must be
done on a regular basis. (7)
The process of high-level disinfection
requires monitoring and auditing. If a
chemical product is used, the
concentration of the active ingredient(s)
must be verified and a logbook of daily
concentration test results is to be
maintained. (34)19
![Page 20: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/20.jpg)
Recall of improperly reprocessed
medical equipment/devices. (10)
The recall procedure should include
assessment of client/patient/resident risk
and a procedure for subsequent
notification of physicians,
clients/patients/residents, other facilities
and/or regulatory bodies if indicated. (73)
20
![Page 21: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/21.jpg)
Health care settings shall have a
process for receiving and
disseminating medical device alerts
and recalls originating from
manufacturers or government
agencies. (74)
21
![Page 22: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/22.jpg)
There must be a regular schedule for
environmental cleaning in the Sterile
Processing Department that includes
written procedures and clearly defined
responsibilities.(18)
Reusable medical equipment/devices
must be thoroughly cleaned before
disinfection or sterilization.(3)22
![Page 23: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/23.jpg)
If cleaning cannot be done immediately, the
medical equipment/device must be submerged
in tepid water and detergent or enzymatic
cleaner to prevent organic matter from drying
on it.(4)
The process for cleaning should include
written protocols for disassembly, sorting,
soaking, physical removal of organic material,
rinsing, drying, physical inspection, lubrication
and wrapping.(6) 23
![Page 24: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/24.jpg)
Two major methods of disinfection:
Chemical
Pasteurization
Pasteurization is a process of hot water
disinfection (minimum 71°C for 30 minutes),
which is accomplished through the use of
automated pasteurizers or washer disinfectors.
Semi-critical medical equipment/devices suitable
for pasteurization include equipment for
respiratory therapy and anesthesia. 24
![Page 25: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/25.jpg)
Disposable sheaths/condoms placed over the
endoscope reduce the numbers of microorganisms
on the scope but do not eliminate the need for
cleaning/disinfection/sterilization between uses. (47)
Endoscope cleaning shall commence immediately
following completion of the clinical procedure. (51)
Patency and integrity of the endoscope sheath
should be verified through leak testing, performed
after each use. (52)
25
![Page 26: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/26.jpg)
Critical endoscopes shall be sterilized. (54)
Semi-critical endoscopes and accessories
(excluding biopsy forceps and brushes) must
receive at least high-level disinfection after
each use. (55)
If an automated endoscope reprocessor
(AER) is used, ensure that the endoscope and
endoscope components are compatible with
the AER. (57)26
![Page 27: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/27.jpg)
Semi-critical endoscopes shall be stored
hanging vertically in a well-ventilated area in a
manner that minimizes contamination or
damage. Endoscopes shall not be coiled,
allowed to touch the floor or bottom of the
cabinet while hanging, or stored in their cases.
(59)
27
![Page 28: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/28.jpg)
Healthcare settings shall have policies in place
providing a permanent record of endoscope
use and reprocessing, as well as a system to
track endoscopes and patients/residents that
includes recording the endoscope number in
the patient/resident record. (62)
28
![Page 29: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/29.jpg)
The preferred method for sterilization of heat-
resistant equipment/devices is steam. (pre-vacuum
sterilizers are preferred). The preferred
sterilization method for heat sensitive instruments
would be low temperature sterilization. (63)
All sterilizers must be tested for performance
using physical, chemical and biological monitors
and indicators. Chemical indicators do not replace
the need to use a biological indicator. (64)
29
![Page 30: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/30.jpg)
Flash sterilization shall only be used in
emergency situations and must never be used
for implantable equipment/devices. (65)
Boiling, use of ultraviolet light, glass bead
sterilization, and use of microwave ovens are
NOT acceptable methods of sterilization. (66)
30
![Page 31: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/31.jpg)
The health care setting must have written
policies regarding single-use medical
equipment/devices. (75)
Critical and semi-critical medical
equipment/devices that are SUDs must not be
re-used unless the reprocessing is done by a
licensed reprocessor. (76)
Needles must be single-use and must not be
reprocessed. (77)31
![Page 32: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/32.jpg)
Catheters, drains and other medical
equipment/devices with small lumens
(excluding endoscopy) be designated as
SUD and not be reprocessed and re-
used, even if designated as reusable by
the manufacturer. (78)

It is not recommended that
housekeeping staff be involved in
cleaning medical devices unless they
have been trained and certified and
moved into the SSD staffing structure.
![Page 40: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/40.jpg)
Educational requirements and qualifications:
Entry level operator: high school leaving certificate
Two-year trained operator: completion of the basic
SSD curriculum
Five-year trained operator or supervisor: completion
of the intermediate SDD curriculum
More than 8 years of training or manager level:
completion of the advanced SDD curriculum
![Page 41: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/41.jpg)
Medical devices processed outside the
SSD cannot be controlled and are
considered unsafe unless these processes
are under the supervision of highly-
trained staff of a similar calibre to those
in the SSD.
41
![Page 42: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/42.jpg)
The of the SSD is to provide
safe, reprocessed, reusable, invasive
medical devices for clinical procedures,
carried out on wards, critical care areas,
ambulatory surgery, nutrition, dialysis and
endoscopy.
The of the SSD is to
receive, clean, decontaminate, package,
sterilize and distribute medical devices.
![Page 43: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/43.jpg)
All spaces used for the reprocessing
of medical instruments must be
equipped with hand hygiene facilities
at the entrance and exit points.
![Page 44: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/44.jpg)
![Page 45: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/45.jpg)
Preparing devices at the point of use does not
replace the cleaning process - it is the beginning of
the cleaning process.
![Page 46: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/46.jpg)
Cleaning is the first and most essential step before
any process of disinfection or sterilization can be
carried out.
One can clean without sterilizing, but one cannot
sterilize without cleaning!
Enzymatic cleaners are NOT disinfectants; they only
remove protein from surfaces.
![Page 47: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/47.jpg)
Brushes should be thermally disinfected and
dried at the end of the day. If this is not
possible, they should be cleaned and left dry.
Brushes must be replaced when damaged.
Chemical disinfection prior to cleaning is
unnecessary, ineffective and of little value in
the presence of organic matter.
![Page 48: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/48.jpg)
![Page 49: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/49.jpg)
Sterilization wrap made from cellulose fibres and
non-wovens made from a combination of cellulosic
and synthetic fibres may be used. Both types are
suitable for porous-load steam sterilization and
most gas processes because they are permeable to
air, steam and other gases.
Rigid reusable sterilization containers should be
suitable for the method of sterilization used and
compatible with the cleaning method and cleaning
agent
![Page 50: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/50.jpg)
Transparent pouches should be placed paper to
plastic for sterilization. Single instruments only
should be packed in pouches
![Page 51: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/51.jpg)
Metal (sterilization) drum trays with holes that can
be opened and closed manually. These do not
guarantee sterility of its contents
Newspapers, brown paper bags and other products
that do not allow air removal or penetration of
steam must not be used
Recycled material packaging because these have lost
their integrity and the bacterial barrier and do not
allow adequate air removal or steam penetration
![Page 52: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/52.jpg)
The total weight of instrument sets and
their packaging should not exceed 10 kg
and the total weight of wrapped basin sets
should not exceed 3 kg.
![Page 53: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/53.jpg)

The preferred method for
sterilization of heat-resistant critical
devices is steam/moist heat
sterilization (pre-vacuum sterilization
is preferred).

Physical (notebook, displays and printout)
Chemical (internal and external indicators)
Biological

Also known as Flash Sterilization.
This sterilization method should be avoided as
the material is sterilized without packaging and
the cycle eliminates drying. As a result, the
possibility of recontamination of the material
increases.

Any person who reprocesses or reuses a device
intended by the manufacturer for single use bears
full responsibility for its safety and effectiveness and
becomes the manufacturer.
![Page 86: APSIC and WHO Sterilization and Instrument Reprocessing Guidelines](https://reader034.vdocument.in/reader034/viewer/2022050614/5a64de6d7f8b9ac21c8b723f/html5/thumbnails/86.jpg)
A reusable device, such as a surgical instrument, is
designed to be used many times on different
patients, and the manufacturer provides detailed
instructions on how it can be safely reprocessed
between each patient.
A single-use device is designed by a manufacturer to
be used on a single patient only and then discarded.
Emphasis is on a “single patient” and a device may
be used multiple times on the same patient,
depending on its design and manufacturers’
instructions.

Don’t do it, but if you do it,
very good reprocessing systems
must be in place
