ABSTRACT
PURPOSE:
Emergency medical services (EMS) response time is one of prehospital factors associated with survival rate of patients with out-of-hospital cardiac arrest (OHCA). The objective of this study was to determine whether short EMS response time was associated with improved neurologic outcome of patients with OHCA through prospective analysis.METHODS:
We performed a prospective observational analysis of collected data from KoCARC registry between October 2015 and December 2016. OHCA patients aged 18â¯years or older with presumed cardiac etiology by emergency physicians in emergency department were included in this study.RESULTS:
Of 3187 cardiac arrest patients enrolled in the KoCARC registry, 2309 patients were included in the final analysis. Response time threshold was 11.5â¯min for prehospital return of spontaneous circulation and 7.5â¯min for survival to discharge and favorable neurologic outcome. Patients in the ≤7.5â¯min response time group showed increased odds of survival to discharge (OR 1.54, 95% CI 1.13-2.10, pâ¯=â¯.006) and favorable neurologic recovery (OR 2.01, 95% CI 1.36-2.99, pâ¯=â¯.001). When response time was decreased by 1â¯min, all outcomes were improved (survival to discharge, OR 1.08; 95% CI 1.04-1.12, pâ¯<â¯.001; favorable neurological outcome, OR 1.14, 95% CI 1.07-1.21, pâ¯<â¯.001).CONCLUSION:
We found that shorter EMS response time could lead to favorable neurologic outcome in patients with OHCA of presumed cardiac origin. EMS response time threshold associated with improved favorable outcome was ≤7.5â¯min.Palavras-chave
