Cardiopulmonary resuscitation outcomes in the emergency department of a tertiary health care centre in north India

Abstract

Background: The purpose of this study was to examine the outcomes of cardiopulmonary resuscitation (CPR) including return of spontaneous circulation (ROSC), survival to hospital discharge and neurological outcome in the emergency department (ED). Methods: This prospective observational study included 233 patients with 51 cases of Out-Of-Hospital Cardiac arrests (OHCA) and 182 cases of In-Hospital cardiac arrests (IHCA). The study was performed in the ED of a tertiary health care centre in North India from July 2018 to June 2021. Results: The majority of the study subjects (67.8%) were males, and the median age of patients was 47 years. 35.6% of cases (N=83) had a sustained ROSC after the first attempt of CPR. Survival to inpatient admission was seen in 20.2% of cases (N=47), and survival to hospital discharge was observed in 3.9% of cases (N=9). Out of 9 cases who survived, 7 cases (3%) were discharged with good neurological outcomes (mRS 0-2). For OHCA, the predictors of survival were witnessed arrest (Odds Ratio [OR]=4.58, 95% CI: 1.08-19.38), bystander CPR (OR=3.78, 95% CI: 1.78-18.13), and time to reach the hospital (OR=0.70, 95% CI: 0.55-0.89). Whereas in IHCA, patients with initial shockable rhythm had increased odds of survival (OR=1.49, 95% CI: 1.35-1.74). Conclusion: In our study, in contrast to the developed countries, the survival to hospital discharge in cardiac arrest patients presenting to ED was very low. Therefore, this study proposes the development of a robust cardiac arrest registry in India, to address the gaps in the existing knowledge and facilitate future research.
