Aim: Cardiac arrests are a critical public health issue, especially in developing countries like India, where access to timely advanced medical care is limited. This study aims to determine the predictors of mortality among patients sustaining in-hospital cardiac arrest (IHCA). Materials and Methods: This retrospective observational cohort study in a tertiary hospital emergency department analyzed one-year IHCA patients. Demographics, causes, and outcomes were recorded from institutional database. Data entered in Excel were analyzed using SPSS version 25.0. Multivariate logistic regression was used to identify independent predictors of mortality among patients presenting with IHCA. Results: Among 267 IHCA patients (mean age 52+/-17 years, male preponderance), hypoxia (43.44%) and coronary thrombosis (25.84%) were the most common reversible causes. Return of spontaneous circulation (ROSC) was achieved in 214 (80.14%) patients, while only 22 (8.23%) had favorable neurological outcomes (mRS <3) at hospital discharge. Logistic regression identified inability to attain ROSC and prolonged resuscitation (>20 minutes) as independent predictors of mortality. Conclusion: Our study underscores the critical importance of achieving ROSC within 20 minutes, through early management of reversible causes, and consistent high-quality chest compressions, which are pivotal for favorable neurological outcomes among survivors.
