OBJECTIVE: Patients with coronary artery disease with diabetes, a history of acute coronary syndromes, cerebrovascular atherosclerotic disease, or peripheral arterial disease are at particularly high risk for a cardiovascular (CV) event and can be defined as having high-risk atherosclerotic cardiovascular disease (ASCVD). The objective of this study is to examine healthcare resource utilization (HRU) and total healthcare costs (THC) for patients with ASCVD in a commercially insured population. METHODS: A retrospective cohort study was conducted using a large, US employer-based, claims database. Patients with an ASCVD diagnosis between October 1, 2008 to September 30, 2009 who met eligibility requirements were included. All-cause and ASCVD-related HRU and THC for the first and second year of follow-up were examined for all patients and by the number of arterial beds affected. Adjusted THC were compared across groups with and without polyvascular disease. RESULTS: The analysis included 152,290 patients with ASCVD. Use of CV-related medications, hospitalizations, and office visits were highest among patients with three arterial beds affected. Mean all-cause THC for patients with ASCVD were ∼$19,000 per patient in Year 1 or Year 2, with medical costs as the main driver. ASCVD-related THC were also similar for Year 1 ($8699) and Year 2 ($7925) across all patients. Adjusted all-cause and ASCVD-related THC for both years were greatest for patients with three affected arterial beds compared with one or two affected beds (p < 0.001 for each comparison). CONCLUSIONS: This is the first study in a managed care setting to systematically estimate all-cause and ASCVD-related THC for an aggregated population of ASCVD patients at high risk for a CV event. The economic burden of ASCVD in working-age patients in the US is substantial. Significantly higher HRU and costs were found in patients with polyvascular disease compared with those with only one affected bed.
