Background: Extracorporeal membrane oxygenation (ECMO) has several applications as a resuscitative intervention, including extracorporeal cardiopulmonary resuscitation (ECPR). ECPR is rarely initiated in the emergency department (ED) by emergency physicians outside regional academic institutions. Objectives: To evaluate whether ECPR improves clinical outcomes after cardiac arrest when initiated by emergency physicians (EPs) in a nonacademic hospital. Methods and Materials: We performed a retrospective analysis of prospectively identified consecutive EP-initiated ECMO subjects from a single community hospital over a 7-year period. Logistic regression and propensity models tested the association between ECPR and survival to hospital discharge compared with concurrent ECPReligible control subjects. Results: Over 7 years (2010-2017), EPs initiated ECMO on 58 subjects; 44 (76%) were venoarterial cases (43 ECPR) initiated in the ED. Of those, 11 (25%) survived to discharge (n = 9 with cerebral performance category score 1) and most were still alive after 5 years (66%). Adjusting for known covariates, ECPR subjects were more likely than concurrent controls to survive to discharge (odds ratio 8.4; 95% confidence interval 1.2-60.4). Propensity analysis revealed a favorable trend toward survival to discharge after ECPR (odds ratio 2.0; 95% confidence interval 0.51-7.8). Conclusions: Emergency physicians initiated ECMO with promising clinical outcomes. Prospective trials are needed to define the efficacy, safety, and costeffectiveness of EP-initiated ECMO.
