What can audit do?
• Identify weaknesses and strengths in structure, processes and outcomes of health care activities
• Help identify specific areas to target rather than feeling overwhelmed by perceived or real failure
• Offers ‘hard’ rather than ‘soft’ evidence for negotiation of resources
• Foster team spirit and morale – recognition of good practice / outcomes
• Develop critical thinking and leadership skills• Significant financial rewards (payment by results)
Limitations of audit
• Can’t offer a quick fix • Can be done to you rather than owned by you• Associated with ‘paper work’ rather than ‘real life’• Can be punitive and disheartening• Can be quite limiting – what is being measured &
what is considered ‘important’ • Quality of service or qualities that are measured?
UH Audit:
• Risk Assessment
• Documentation of Risk
• Risk factors
• Contra-indications to chemical and mechanical interventions
• Accurate prescription of TP
• Has patient received the appropriate prescription?
All Party Thrombosis Group Audit.
• Audits in 2007 & 2008• Data collection Tool sent to CEO’s
In 2008• 99% of 138 Acute Trusts surveyed replied• 86% have Thrombosis Committees• 93% of Acute Trusts have written TP policy• 70% of Acute Trusts undertake a
documented mandatory risk assessment
Real Life Experiences - Endorse
Challenges with collecting Data
– Length and complexity of form
– Time
– Recruitment of volunteers to collect data
– Lack of ownership of audit
Endorse - Local Trust Findings• Most patients have Risk Assessment Model
(RAM) in notes because it is attached to clerking performa
• Many patient’s risk assessment documentation not completed
• If RAM completed sometimes recommended thromboprophylaxis is not prescribed
• Thromboprophylaxis prescribed but no risk assessment completed
• TEDS often prescribed but not fitted
Endorse – Local Findings
• The only unit with 100% of patients risk assessed and 100 % appropriate thromboprophylaxis given was the surgical pre-assessment unit.
• Nurses perform assessment and ensure doctors write prescription.
Student Audits at UH
• 320 students to date
• Average number of patients each student audits = 30
• Total number audited = 9,600
Real Life Experience - UH course
Common Themes:– Staff unaware of existence of RA Model or TP protocol– Risk assessment not documented (assumption it hasn’t
happened)– More nurses completed risk assessment than doctors– Information from Risk Assessment not transferred to
Prescription Chart– Limited prescription of TP despite risk assessment – Many prescriptions do not follow Trust protocol (especially
for anti-embolic stockings)– Results can be influenced by where and when risk
assessment takes place in patient journey.– Having a protocol and documentation in place is not an
end in itself.
Trends
• Increase in number of Thromboprophylaxis Committees, comprehensive protocols and Risk Assessment Models
• Poor completion of Risk Assessment Models• Increased prescription of Thromboprophylaxis• Increased number of Trusts using opt out system• Continued resistance and lack of awareness
Summary
• UH student feedback support All Party Thrombosis Group findings
But• Poor quality of patient documentation • Need appropriate audit questions• Need audits that can be owned by local staff• Need to review and update audit questions as
Trusts develop their effectiveness in TP• Need feedback at unit level• Need continuous education to all staff regarding
best practice for TP
Strategy for VTE prevention auditNeeds to be relevant to ward, hospital and Trust
Ask:• Is there a Risk Assessment Model in place?• Is this Model being used?• Where and when in patient’s journey is risk assessment
taking place?• Is TP being prescribed?• Is it appropriate TP, are there contraindications and has it
been given?• Who is completing risk assessment and prescribing TP?
This should be mandatory to ensure audit assesses
quality of TP not just the presence of documentation.
