Cost of illness for chronic stable angina patients enrolled in a self-management education trial

BACKGROUND: Chronic stable angina (CSA) is a major debilitating health problem in Canada. A paucity of relevant cardiovascular data sets has precluded a detailed examination of the impact of interventions on CSA-related costs and its broader economic burden. OBJECTIVES: As part of a larger clinical trial, the authors sought to determine the short-term impact of a standardized self-management training program on CSA-related costs. A secondary objective was to estimate the total annualized cost of CSA per patient from a societal perspective. METHODS: Pre- and three-month post-test cost data were collected oil 117 participants using the Ambulatory Home Care Record. Mean annualized direct, indirect and system-related CSA costs (1003 to 2005) were estimated; total per-patient CSA costs from a societal perspective were calculated as the sum of these costs. RESULTS: The mean (+/- SD) age of participants was 68 +/- 11 years; 80% were male. The program did not impact costs in the short-term. Direct annual out-of-pocket costs, including money paid for health care, travel to appointments, medication, equipment and home support totaled $3,267. Indirect costs, reflecting the value of all unpaid time spent by those engaged in angina-related care, were $12,963. System costs, including costs paid by public and private insurers, were $2,979. Total estimated annual CSA costs from a societal perspective ware $19,209 per patient. CONCLUSIONS: These data suggest that CSA imposes a major economic burden, comparable with other prevalent conditions such as chronic noncancer pair). Advancements in self-management training research :ire needed to help reduce the economic burden of CSA in Canada.
