Predictors of Mortality in Out-of-hospital Cardiac Arrest (OHCA) Patients: A Retrospective Cross-sectional Study from the Sultanate of Oman

Background: Out-of-hospital cardiac arrest (OHCA) is a significant global health challenge with high incidence and low survival rates; this study aimed to predict mortality in these patients. Methods: This 5-year retrospective chart review, conducted at the emergency departments (EDs) of two tertiary hospitals, systematically categorized, coded, and analyzed variables to assess mortality risk in OHCA patients. Overall, 49 patients (8.4%) survived to hospital discharge. Conclusion: Elderly males with hypertension, diabetes, respiratory ailments, and multiple comorbidities constituted a significant risk group. Factors such as prior episodes of chest pain and fluid overload were associated with higher mortality. Patients with asystole and PEA had low survival rates.
