OBJECTIVES: We sought to estimate the direct costs (in-hospital and 30-day) associated with an intraprocedural thrombotic event (IPTE) among patients with non-ST-segment elevation acute coronary syndromes (NSTEACS) undergoing percutaneous coronary intervention (PCI). BACKGROUND: Patients with IPTE have higher rates of in-hospital and 30-day major adverse cardiac events than patients without IPTE. The extent to which IPTE also add to medical costs is unknown. METHODS: Hospital costs for patients in the ACUITY Trial were compared between patients with and without IPTE. Adjusted comparisons were performed using generalized linear models (GLMs). All costs are reported in 2012 US dollars. RESULTS: A total of 1,307 patients with both core laboratory-based angiographic assessment and detailed economic data were included in the final study population. IPTE occurred in 52 patients (4.0%). Median in-hospital costs were higher in patients with IPTE than in those without IPTE ($23,719 vs. $18,419, P = 0.01). Thirty-day median costs were also higher for IPTE patients ($23,719 vs. $19,556, P = 0.05). After adjusting for baseline differences, IPTE was associated with 19.5% (95% CI: [2.8-38.8%], P = 0.02) and 18.9% (95% CI: [1.2-39.7%], P = 0.04) increases in in-hospital and 30-day costs, respectively. These relative differences represent median increases of $3,592 in initial hospital costs and $3,696 in 30-day costs. CONCLUSIONS: The occurrence of IPTE during the index PCI in patients with NSTEACS is associated with substantial increases in-hospital and 30-day costs. These findings suggest that strategies to prevent IPTE may be associated with important cost offsets as well as improved clinical outcomes.
