Abstract

BACKGROUND: Chest pain is among the most common reasons for presentation to the emergency department (ED) worldwide. Additional studies on most cost-effective ways of differentiating serious vs. benign causes of chest pain are needed.

OBJECTIVES: Our study aimed to evaluate the effectiveness of a novel risk stratification pathway utilizing 5

METHODS: A retrospective chart review was performed 6 months prior to and after the implementation of a novel risk stratification pathway that combined hs-cTnT with HEART score to guide evaluation of adult patients presenting with nontraumatic chest pain at a large academic quaternary care ED. Primary outcome was ED length of stay (LOS); secondary outcomes included cardiology consult rates, admission rates, number of ED boarders, and number of eloped patients.

RESULTS: A total of 1707 patients and 1529 patients were included pre- and postimplementation, respectively. Median overall ED LOS decreased from 317 to 286 min, an absolute reduction of 31 min (95% confidence interval 22-41 min), after pathway implementation (p < 0.001). Furthermore, cardiology consult rate decreased from 26.9% to 16.0% (p < 0.0001), rate of admission decreased from 30.1% to 22.7% (p < 0.0001), and number of ED boarders as a proportion of all nontraumatic chest pain patients decreased from 25.13% preimplementation to 18.63% postimplementation (p < 0.0001).

CONCLUSIONS: Implementation of our novel chest pain pathway improved numerous ED throughput metrics in the evaluation of nontraumatic chest pain patients.
