Relevance of Simulation Practices for Improving the Internalization of Cardiopulmonary Arrest Management Protocols

Effective training in cardiopulmonary arrest (CPA) management is crucial for future healthcare professionals, as timely actions impact survival. Despite standardized AHA protocols, their practical internalization remains difficult. Simulation-based medical education (SBME), particularly with structured debriefing like the PEARLS model, has become essential for developing competencies in safe environments. The objective of this study was to evaluate the relevance of deliberate simulation practices (zones 1 and 2) in improving theoretical understanding and CPA protocol adherence among medical students. Objective Methods: A quasi-experimental pre-post study was conducted at the Clinical Simulation Laboratory (LaSiC), Faculty of Medical Sciences, University of Buenos Aires. Ten teams of final-year medical students participated voluntarily in a 30-hour simulation workshop over five weeks. The program included asynchronous theoretical content and in-person sessions: basic skills training (Zone 1) and eight high-fidelity scenarios (Zone 2) emphasizing teamwork. After each scenario, a structured debriefing based on the PEARLS model was conducted, fostering self-assessment, facilitation, and feedback. Internalization was measured via an anonymous pre-post questionnaire. Results: Correct questionnaire responses improved significantly, from a pre-test average of 66.24% to 83.3% in the post-test. Some scenarios showed increases of up to 56.3%, indicating effective protocol incorporation. Deliberate practices across simulation zones supported the development of individual and team competencies. The PEARLS model was key for reflection and consolidation. Despite limitations (no control group, indirect measurement), findings suggest a strong association between the intervention and improved outcomes Conclusion: A simulation workshop using deliberate practices and structured debriefing (PEARLS model) is an effective strategy to enhance CPA protocol internalization and develop essential technical and non-technical skills in medical students
