Changing culture: Perspectives on transforming clinical microbiological practice Dr Valerie Bevan Head of Department for Evaluations, Standards and Training valerie.bevan@hpa.org.uk www.evaluations-standards.org.uk Celebrating 25 years of the BSMT 14 May 2010
Influencing factors Health and safety Quality Methods Technology Other influences Political Financial Education & training Science Professional Customer Cultural Equality and diversity (race, disability, gender, age, sexual orientation, religion and belief) Structure of talk
Health and safety • 1957 lab workers 2-9 times more likely to die of TB than others • 1969-70 Edinburgh - hepatitis outbreak (8 pts; 3 staff died) • 1973 London School of Hygiene - Smallpox escape • Perceptions of risk
Health and Safety • Health and Safety at Work etc Act 1974 • Howie Report 1978, 1983 (JW Howie and CH Collins) • Report of the Working Party to Formulate a Code of Practice for the Prevention of Infection in Clinical Laboratories (the "Howie Report") • The Howie Code (1978) • Code of Practice for the Prevention of Infection in Clinical Laboratories and Post-mortem Rooms (the “Howie Code")
Howie Report • Although an early draft had been "leaked“ and was published in a trades union journal the Report has not been published by the Department. • The reasons for this were never made clear to members of the Working Party which produced it, nor to the newspapers which supported publication. • It may be relevant here to note that only one of the five recommendations made in the Report (testing of equipment by the PHLS) has been implemented. • For details see Howie and Collins ‘The Code of Practice’
H&S Legislation • Health and Safety (Dangerous Pathogens) Regulations 1981 • Control of Substances Hazardous to Health Regulations 1988 (COSHH) (EC Directive 80/1107/EEC) • Amended 1996, 1887, 1998, 2001 • Replaced by 2002 COSHH Regulations (EC Directive 98/24/EC) (amended 2003, 2004)
H&S • Advisory Committee on Dangerous Pathogens (ACDP) "Categorisation of biological agents according to hazard and categories of containment" 4th ed, 1995 • ACDP "The management, design and operation of microbiological containment laboratories" published 2001 • Health Services Advisory Committee (HSAC) guidance, "Safe working and the prevention of infection in clinical laboratories and similar facilities" (updated in 2003) • ACDP 2005 "Biological agents: managing the risks in laboratories and healthcare premises"
Is it true that more Americans who were in the Twin Towers have died in car crashes since 9/11/2001 than died in the 9/11 atrocity? • Car crashes kill 400 times more people than international terrorism does in developed countries
History of Quality • Guilds system (12th-19th Century - master craftsmen, journeymen) • Industrial revolution (18th-19th Century, mass production) • Rise of technology (tools, machines, factories, iron prod) • Mass production (Ford cars) • 1st World War (munitions) • Need for inspection • Technical Inspection Association (1919) • Walter Shewart (QC stats 1920s)
History of Quality • Post WW2 quality (Japan, Toyota) • 1980s (quality revolution in US) • 1990s (service industries, JIT, TQM, Six Sigma, ZDP, Benchmarking, LEAN etc) • 1970 external quality assessment (40th anniversaries) • Late 1980s (CPA-UK) lab accreditation • ISO 9001:2000 – Quality Management System • ISO 13485:2003 – QMS for Medical Devices
Quality • IVD Directive 98/79/EC on in vitro Diagnostic Medical Devices • 2002 UK - Medical Devices Regulations – consumer protection • 2008-9 (CPA-UKAS) • ISO 15189:2003 – International standards for medical laboratories • EC Medical Devices Directives – Guidance Notes on in vitro Diagnostic medical devices 98/79/EC (The CE Marking) • NICE • EBM
What do we mean by “Quality”? • “The degree to which a set of inherent characteristics fulfils requirements” • ISO 9000
What do we mean by “Quality”? • What do you look for in a car? • Point A to point B? • Speed? • Colour? • Manual vs Automatic? • Diesel vs Petrol? • Good stereo? • Practicality vs styling?
What do we mean by ‘Quality’? A subjective term for which each person has his or her own definition • In technical usage, quality can have two meanings: • the characteristics of a product or service that bear on its ability to satisfy stated or implied needs • a product or service free of deficiencies • Source: American Society for Quality http://www.asq.org/glossary/q.html
Quality in the laboratory • The right result on the right specimen from the right patient that is accurate, timely, and properly interpreted

What do we mean by Quality Management? Quality Management System (QMS) • Quality manual • Meeting accreditation standards • Adequate quality assurance (EQA, IQC, IQA) • Validated methods, equipment & kits • Having good SOPs
What do we mean by assuring quality? • Having a ‘service culture’ focussed on the user / clinician and patient • Timely, high quality clinical advice and interpretation of results • Good reporting of all diseases for surveillance • Public health focus
Quality Accounts DH expectations • Quality Accounts should assume the same significance for NHS as financial accounts • For the first time, all organisations will account publicly for the quality of care they provide • The first Quality Accounts will (subject to legislation) be published in 2010, based on information about quality improvement in 2009/10 • Measures therefore need to be identified and in place prior to April 2009
