Abstract
Background: Out-of-hospital cardiac arrest (OHCA) is a major public health problem. Because of the low surviving rate, caring for OHCA patients is time-sensitive and requires an effective emergency medical services (EMS) team. The COVID-19 outbreak in Thailand may affect clinical outcomes in these patients. Objective: To study the impact of the COVID-19 outbreak on survival in OHCA patients Methods: This was a retrospective cohort research. We studied 198 adult non-traumatic OHCA patients treated by the Chonburi Hospital's EMS team between 1 Feb 2018 and 31 Dec 2021. We set the period after 13 Feb 2020 as the COVID-19 outbreak in Thailand. Multiple logistic regression was used to analyze the effect of the COVID-19 outbreak on survival outcomes. Results: Most of the subjects were male (68.21%). The average age was 59.63±16.70 years. The proportions for return of spontaneous circulation (ROSC), 48-hour survival, and survival to discharge for all patients were 39.29%, 4.59%, and 3.06%, respectively. There were differences in age, time shift of incident, initial EKG rhythm, and total cardiopulmonary resuscitation (CPR) of the patients during the COVID-19 outbreak. There was no statistically significant effect of the COVID-19 outbreak on the survival of the patients. The factors that affected survival was shockable EKG, the on-scene time, and total CPR time. Conclusion: The COVID-19 outbreak in Thailand had no impact on the survival of non-traumatic OHCA patients
