NO CONFLICT OF INTEREST TO DECLARE
Audit: Background Clinical Governance –The systematic approach to maintaining and improving the quality of patient care in a health system Recognisably high standards of care Transparent responsibility and accountability for those standards A constant dynamic of improvement
Clinical Governance Education and training –continued professional development Clinical effectiveness –the appropriateness, efficacy, cost effectiveness and safety of different therapies. Research and development –the application of new research findings into clinical practice and guideline development. Openness –Poor practice can thrive if it occurs out of the scrutiny of peers, and while openness is important, it must respect appropriate individual patient and practitioner confidentiality. Risk management –addressing and minimising risks to patients, physicians and organisations. Clinical audit
Clinical Audit Greatest potential to assess quality of care Domains –Structure –Appropriateness –Process –Outcomes

Randomised Control Trials Strengths –Randomisation –Ability to test hypotheses –Cause and effect conclusions –Precise and robust analysis Weakness –Focused entry criteria –costs limit patient number and FU duration ESC STEMI Guidelines 13% based on RCTs (Tricoci P JAMA 2009;301:831) Euro Heart Survey up to 89% wld be excluded from RCTs (Hordijk_Trion M EHJ 2006;27:671)
Registry Strengths –Generalised entry full spectrum including high risk patients included –Population outcomes –Long follow up –Large numbers of patient assessed –Suited to Risk Modelling Weaknesses –Non randomised –Observational –Hypothesis generating (cause v effect uncertain)
