Relative Factors for Survival Outcome of Out Hospital Cardiac Arrest Patient in Det-Udom District, Ubon Ratchathani

Introduction: This study aimed to identify factors related to the survival outcome of out-of-hospital cardiac arrest patients in the emergency department at Det-Udom Crown Prince Hospital. Methods: This retrospective descriptive study collected data of out-of-hospital cardiac arrest patients at the emergency department during January 2022 and December 2023 from the hospital database. The data was analyzed by descriptive statistics and the Chi-square test or Fisher’s exact test. Results: Among the 168 patients, 72% were male, age average, 55 years. Incidents occurred at home (56.5%), and cause of cardiac arrest by accidents being (31.5%). The sustained return of spontaneous circulation was 25.8%. The survival to hospital admission was 24.1%, and survival with a good neurological outcome (Cerebral Performance Category; CPC) Cat I-II was 2.15%. The factors significantly associated with out-of-hospital cardiac arrest survival (P-value<0.05) were as follows: The associated factors of failure in resuscitation were diabetes (Odd = 2.676), hypertension (Odd = 2.333), and cardiac arrest due to accidents (Odd = 2.509). During transportation factors associated with improved patient survival; defibrillator use (Odd = 0.430), chest compressions (Odd = 0.417), fluid administration (Odd = 0.430), and adrenaline administration (Odd = 0.467). Additionally, factors related to emergency medical services include response time, on-scene time, chest compression techniques, opening the airway, oxygenation, and type of ventilation. Conclusion: Enhancing cardiopulmonary resuscitation (CPR) skills, expanding emergency medical response units to cover broader areas, and ensuring rapid access to emergency medical services can significantly increase the survival rate of out-of-hospital cardiac arrest patients.
