Factors Affecting Survival Outcome in Out-Of-Hospital Cardiac Arrest Patients at Emergency Room, Banglamung Hospital, Chonburi

Abstract

Out-of-hospital cardiac arrest (OHCA) has shown low rate of survival. There were benefits from studing factors affecting survival outcome in out-of-hospital cardiac arrest and learned from problems for improving emergency medical services (EMS). These could increase the survival rate of OHCA patients. This retrospective study aimed to study factors affecting survival outcome in out-of-hospital cardiac arrest at emergency room, Banglamung hospital; collecting data from OHCA medical records database, between January 2023 and December 2023. There were 110 patients enrolled; return of spontaneous circulation (ROSC) was observed in 40.9% of the cases, survival to admit 10.9% and survival to refer 9.1%. As for the result from data analysis; significant factor affecting survival outcome (p<0.05) was time to first dose adrenaline within 30 minutes. Thereby OHCA patients who got first dose adrenaline within 30 minutes had greater chance of ROSC, 3.53 times than those who got first dose adrenaline more than 30 minutes (95%CI: 1.49 - 8.34, p<0.05). Therefore, OHCA patients should got first dose adrenaline as soon as possible to increase the chance of survival.
