Key Points

To assess the effectiveness of simulation-based CPR training on medical students' performance and confidence, and its impact on patient outcomes.
Single-center, prospective observational study with 1000 medical students.
Participants underwent AHA-certified BLS and ACLS training with performance evaluated using standardized checklists.
Confidence measured via structured surveys, analyzed alongside patient outcome data from 103 resuscitation cases.
Mean BLS and ACLS scores improved from 65% to 85% and 60% to 80%, respectively.
Chest compression, ventilation, and defibrillation performances significantly increased, with ROSC rates rising from 60% to 78%.
Student confidence increased from 40% to 85%.

Abstract

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.
