The cardiopulmonary resuscitation team performance, the resuscitation outcomes, and the associated factors in a teaching hospital in Iran

Introduction: The outcomes of Cardiopulmonary Resuscitation (CPR) depend on the performance of the CPR team. Poor team performance endangers patient safety and leads to poor CPR outcomes. Objective: This study aimed to evaluate the performance of CPR teams in teaching hospitals of Zanjan, Iran, the resuscitation outcomes (patient survival/death), and the associated factors. Materials and Methods: This observational descriptive-analytical study was conducted from June 2024 to February 2025 in two teaching hospitals affiliated with Zanjan University of Medical Sciences, Zanjan, Iran. Fifty in-hospital CPR events were evaluated over 10 months (five per month) using the Team Emergency Assessment Measure (TEAM). A total of 290 team members participated in these 50 events. Statistical analysis was performed using descriptive statistics, the Kolmogorov-Smirnov test, Spearman's correlation test, and the Mann-Whitney U test. Results: The patients had a mean age of 71.38 ±6.68 years, were mostly male (60%), and had cardiac disease as the primary cause of CPR (74%). The total TEAM score was 30.20±7.02 (out of 44). The highest mean score was in the task management domain (5.88±1.45), and the lowest was in the leadership domain (4.84±1.71). The analysis revealed a significant difference in total TEAM score based on CPR outcome (P = 0.001). There was a significant negative relationship with the call-to-arrival interval and total TEAM score (r = –0.582, P = 0.001), a signifcant positive correlation between experience in critical care units and the teamwork domain score (r = 0.323, P = 0.022), and a signifcant negative correlation between team size and the teamwork domain score (r = –0.303, P = 0.033). Conclusion: The results reveal the suboptimal performance of the CPR team in teaching hospitals of Zanjan, particularly in the leadership domain. Education of teamwork and leadership skills and shortening of the call-to-arrival interval can improve the CPR team performance and CPR outcomes.
