Abstract

Introduction: The survival rates of out-of-hospital cardiac arrest (OHCA) depend not only on rapid access to emergency medical services (EMS) but also critically on the ability and actions of bystanders.

Research objectives: This study aimed to examine factors associated with the return of spontaneous circulation (ROSC) in patients experiencing OHCA within 30 minutes prior to hospital arrival.

Research methodology: This retrospective study used data from medical records identified by the ICD-10 code for OHCA. The data came from a community hospital that provided outpatient and emergency services 24 hours a day. There were 90 cases included in the analysis. The research instrument was a structured data collection form for OHCA patients. It consisted of two parts: 1) general patient information and 2) variables derived from the conceptual framework. Content validity was assessed using the Index of Item-Objective Congruence. Values ranged from 0.60 to 1.00 for all items. Descriptive statistics, Chi-square tests,
and independent t-tests were used for statistical analysis.

Results: Age and comorbidities did not differ significantly between ROSC and non-ROSC groups (p > .05). In contrast, the suspected cause of cardiac arrest was the only covariate with a statistically significant difference between groups (p < .05). These three variables were analyzed for survival outcomes without covariate adjustment. EMS transport was significantly associated with ROSC (p < .05). No significant associations were found between the presence of a witness and ROSC, or between bystander CPR before hospital arrival and ROSC (p > .05).

Conclusions: The time from the emergency call to hospital arrival via EMS does not affect survival rates. Chest compressions performed by bystanders before EMS arrival do not significantly increase survival chances.

Implications: Efforts should focus on enhancing the quality of CPR delivered by community bystanders and optimizing EMS performance. Furthermore, the deployment of advanced life support teams is essential to provide timely and effective resuscitation.
