Safe and rapid disposition of low-to-intermediate risk patients presenting to the emergency department with chest pain: A 1-year high-volume single-center experience
2014
Abstract Background Coronary CT angiography (CTA) is a powerful tool for the evaluation of chest pain in the emergency department (ED). Some debate persists regarding its cost-effectiveness in a low-to-intermediate risk population. Objective This study sought to evaluate the safety and cost-effectiveness of coronary CTA for low-to-intermediate risk patients presenting to the ED with chest pain in a closed-loop referral system. Methods Chest pain patients were evaluated in the ED via a local rapid coronary CTA protocol and tracked prospectively for ED throughput, disposition, chest pain recidivism, and cost utilization as compared with an age-matched cohort evaluated for chest pain treated with usual care. Results One hundred eighty-three patients underwent the rapid coronary CTA protocol compared with an age-matched cohort of 184 patients treated with usual care. The median follow-up period for major adverse cardiovascular events in the coronary CTA group was 9.0 months (range, 1.8–14.5 months) and 11.1 months (range, 0–14.0 months) for the age-matched cohort. The median ED length of stay (LOS) was 5.8 hours (range, 2.6–12.3 hours) for the rapid coronary CTA cohort and 12.2 hours (range, 1.7–40.3 hours) for the age-matched cohort ( P P P P Conclusions Coronary CTA for ED risk stratification and disposition within a closed referral system resulted in the shortest ED LOS published to date while being safe and cost-effective.
