Issues influencing development of the Canadian Cardiovascular Information Network.
The 1995 Consensus Conference of the Canadian Cardiovascular Society on "Indications for and Access to Revascularization" recommended that Canadian centres with invasive cardiovascular facilities should participate in a national observational database that monitors the selection of patients, as well as evaluate outcomes. The Canadian Cardiovascular Society, the Heart and Stroke Foundation of Canada, and Health Canada with IBM as a partner, initiated a process to identify factors influencing the development of the Canadian Cardiovascular Information Network. IBM's "Business Discovery Methodology" was adapted for health care. Structured interviews with representatives of health organizations, cardiovascular databases and research institutes were conducted across Canada, followed by a workshop to identify goals, issues and challenges. Participants identified goals for a cardiovascular database (eg, evidence-based decision-making), project related issues (eg, respecting the integrity of existing databases) and health care related issues (eg, cardiac waiting lists). Challenges included initial mistrust between representatives of provincial cardiovascular databases and national agencies, and a lack of sustained funding. A Project Team was formed to address 'cardiac waiting lists'. Analysis of Alberta and Ontario data identified differences in definitions, such as when the waiting time for bypass surgery began, that impeded detailed comparisons. Development of a centralized national database was not feasible at this time for political, technical and financial reasons. However, provincial cardiovascular database representatives agreed to work together and to share aggregate data and analyses. A first step toward developing a national surveillance system for cardiovascular services will be achieving consensus about standardizing data definitions. This process will require sustained funding.
