Robert Liston
• 1st Professor of Surgery UCL• 1st Operation under GA in Europe• Prior to anaesthetics:
– Speed• ↓ Pain Survival
• Quality = Speed– “the fastest knife in the West End. He could
amputate a leg in 2 ½ minutes”
![Page 7: Quality Standards for Patients Treated by PCI Peter F Ludman.](https://reader035.fdocuments.net/reader035/viewer/2022070409/56649e855503460f94b880f7/html5/thumbnails/7.jpg)
• A High Quality Service?
• Results:– Amputation 2 ½ minutes
• Patient died from gangrene
– Assistant’s fingers inadvertently cut through• Assistant died from gangrene
– Cut coat tails of distinguished surgical spectator• Died of ‘fright’

Trolley waits
• It is unacceptable that some patients have to wait on trolleys before being admitted to hospital
• 2000 target– Trolley wait to < 12 hr
• 2004 target– Trolley wait < 4 hours

Target ‘reports’• Inadequate resource Creativity
• Patients held in ambulances– clock doesn't start

• 66% of all patients are sent to ward in last 10 min of 4 hours deadline
• ? Correct decision
• ? Correct wards

Measurement of Quality
• Aim– Highest quality of care for patients– Outcomes are the true measure of quality
• But– No single outcome captures results of care– Measures may be too narrow
• single department / single intervention• May destabilize care in unmeasured area
– Measures may be too broad• entire hospital rates of acquired infection
– Measure of process are convenient but surrogates– Measurement leads to gaming

Features for Outcome measures
• Important to patients
• Occurrence sufficiently frequent
• Features to incorporate entire hierarchy
• Practical issues regarding measurement– Care with measures that encourage gaming– Objective, standardised and clearly defined– Methods for gathering data

Quality Standards
• Specific concise statements that:– Act as markers of high quality, cost-effective
patient care across a pathway or clinical area– Derived from best available evidence– Produced collaboratively with NHS and social
care, with their partners and service users

Use of Quality Standards• Patients and Public
– Information regarding the quality of care they can expect to receive
• Clinical staff– Ensure care provided is based on latest evidence and best practice
• Audit• Governance• Professional development and revalidation
• Provider organisations– A framework for Quality Accounts– Assess the quality of care being delivered– Highlight areas for improvement and monitor changes
• Commissioners– Ensure best care being delivered via contracting process– Incentive payments (Commissioning for quality improvement CQUIN)– Demonstration of World Class commissioning competencies

• Overview of the politics of ‘Quality Standards’• Clinical governance and quality of patient care is
underpinned by standards
• Not measured not assessed• Once measured inevitable change in its value• Many hidden traps to what you measure and
