Prevalence and Predictive Factors of Return of Spontaneous Circulation in Traumatic Out-of-Hospital Cardiac Arrest in Samutsakhon Hospital

Abstract

Accident-related injuries are the leading cause of out-of-hospital deaths worldwide. Traumatic cardiac arrest has a low survival rate. Currently, there is no clear prognostic factor for predicting the outcome in this patient group. The researchers are interested in studying the prevalence, survival rate, and predictive factors of return of spontaneous circulation (ROSC) in traumatic out-of-hospital cardiac arrest, through a retrospective study involving patients with traumatic out-of-hospital cardiac arrest presenting to the Emergency Department at Samutsakhon Hospital, between October 2017 and September 2025. The study calculated the prevalence and to calculate the prevalence and predictive factors associated with emergency department (ED) survival. Chi-square test or Fisher Exact test was used for categorical data, while independent t-test was used for normally distributed continuous data. In cases where the data were not normally distributed, the Mann-Whitney U-test was applied. The results showed that among the 166 patients with traumatic out-of-hospital cardiac arrest in this study, there were 44 successful resuscitations in the emergency department, accounting for 26.5%, and 4 patients survived to be discharged home, representing 2.4%. Prehospital ROSC was the only factor significantly associated with ED survival, increasing the chance of successful resuscitation in the emergency department by 5.8 times.
