Quality of Care for Percutaneous Coronary Intervention: Development of Canadian Cardiovascular Society Quality Indicators

Abstract

Currently there are more than 40 centres in Canada that perform more than 65,000 percutaneous coronary interventions (PCIs) in a year. Considering the high volume of procedures and number of operators, the potential for variation in processes of care is high, and might lead to variation in the quality of care. As part of its quality initiative, the Canadian Cardiovascular Society convened a working group to develop a set of PCI Quality Indicators (QIs) that would be relevant, scientifically acceptable, and feasible to measure and report. The working group was comprised of clinical experts from across Canada and members of provincial and federal organizations involved in promoting the quality of health care. Using the Canadian Cardiovascular Society "Best Practices for Developing Cardiovascular Quality Indicators" methodology, a total of 23 QIs were proposed. Subsequent ranking and discussion led to the selection of 8 QIs. The selection and ranking of QIs were on the basis of clinical importance and relevance, scientific acceptability, and feasibility of their operationalization at a national level. The data definitions and technical notes of the QIs were refined after feasibility testing and Web consultation. Feasibility testing indicated that standardization and enhancements of knowledge infrastructure are essential to provide the comprehensive patient data necessary to evaluate the quality of PCI across Canada.
