Simulation-based training: Assessment of impact on medical students’ performance, confidence in CPR, and patient outcomes – A single-center study

BACKGROUND: Cardiopulmonary resuscitation (CPR) is an essential life-saving procedure. Traditional training methods may not sufficiently prepare medical students for real-world emergencies. Simulation-based training offers a high-fidelity, immersive approach to teaching CPR skills. To assess the effectiveness of simulation-based CPR training on medical students’ performance and confidence, and to evaluate its impact on real patient outcomes. MATERIALS AND METHODS: A single-center, prospective observational study was conducted at Chettinad Academy of Research and Education (CARE) from January 2022 to June 2024. A total of 1000 medical students underwent AHA-certified BLS and ACLS training. Performance was assessed pre- and post-training using standardized AHA checklists. Student confidence was measured using structured surveys developed by the Department of Community Medicine. Patient outcome data from 103 real-life resuscitation cases involving these students were analyzed. RESULTS: Post-training, mean BLS and ACLS scores improved from 65% to 85% and 60% to 80%, respectively. Significant gains were observed in chest compression (70% to 90%), ventilation (60% to 85%), defibrillation (55% to 80%), and protocol adherence (60% to 85%). Student confidence rose from 40% to 85%. Patient outcomes improved notably, with return of spontaneous circulation (ROSC) rates increasing from 60% to 78%. CONCLUSION: Simulation-based CPR training significantly enhanced both skill performance and confidence among medical students, and contributed to improved patient survival during clinical resuscitation events.
