Robert Liston 1794-1847
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”
Robert Liston
• 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

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

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
Quality Standards
http://www.nice.org.uk/guidance/qualitystandards/
• 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
National Quality Board
• Established 2009
• Champion quality and ensure alignment
in quality throughout NHS
• ‘Multi-stakeholder’ board

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

Conclusion
• 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
how you use it to improve a service
