British Cardiovascular Intervention Society registry framework: a quality improvement initiative on behalf of the National Institute of Cardiovascular Outcomes Research (NICOR).

AIMS
The British Cardiovascular Intervention Society (BCIS) percutaneous coronary intervention (PCI) registry is hosted by the National Institute of Cardiovascular Outcomes Research (NICOR) at Bart's Heart Centre and collects clinical characteristics, indications, procedural details and outcomes of all patients undergoing PCI in the United Kingdom. The data are used for audit and research to monitor and improve PCI practices and patient outcomes.


INTERVENTIONS
Bespoke live data analysis and structured monthly reports are used to provide real time feedback to all participating hospitals about the provision of care. Risk-adjusted analyses are used as a quality metric and benchmarking PCI practices.


POPULATIODN & SETTINGS
Consecutive patients undergoing PCI in all PCI performing hospitals in the UK.


YEARS
From 1994 to present.


BASELINE DATA
113 variables encompassing patient demographics, indication, procedural details, complications and in-hospital outcomes are recorded.


DATA CAPTURE
Prospective data is collected electronically and encrypted before transfer to central database servers.


DATA QUALITY
Data is validated locally and further range checks, sense checks and assessments of internal consistency are applied during data uploads. Analyses of uploaded data including an assessment of data completeness are provided to all hospitals for validation, with repeat validation rounds prior to public reporting.


ENDPOINTS
In-hospital PCI complications, bleeding and mortality. All-cause mortality is obtained via linkage to the Office of National Statistics. No other linkages are available at present.


DATA ACCESS
Available for research by application to NICOR at http://www.nicor.org.uk/ using a data sharing agreement.
