The Myocardial Ischaemia National Audit Project (MINAP)

Quality Of Care Interventions: Feedback to hospitals, ambulance services and cardiac networks regarding benchmarking of performance against national standards and targets.

Setting: All 230 acute hospitals in England and Wales. Years: 2000-present.

Population: Consecutive patients, unconsented. Current number of records: 735 000.

Startpoints: Any acute coronary syndrome, including non-ST-elevation myocardial infarction, ST-elevation myocardial infarction and unstable angina.

Baseline Data: 123 fields covering demographic factors, co-morbid conditions and treatment in hospital. No blood resource.

Data Capture: Manual entry by clerks, nurses or doctors onto Lotus Notes; non-financial incentives at hospital level.

Data Quality: Hospitals perform an annual data validation study, where data are re-entered from the case notes in 20 randomly selected records that are held on the server. In 2008 data were >90% complete for 20 key fields, with >80% completeness for all but four of the remaining fields.

Endpoints And Linkages To Other Data: All-cause mortality is obtained through linkage with Office for National Statistics. No other linkages exist at present.

Access To Data: Available for research and audit by application to the MINAP Academic Group. http://www.rcplondon.ac.uk/CLINICAL-STANDARDS/ORGANISATION/PARTNERSHIP/Pages/MINAP-.aspx.
