Introduction Simulation-based interprofessional education (Sim-IPE) enables health professions students to collaborate in a realistic, safe, simulated clinical environment. Debriefing is a critical component of simulation, facilitating reflective learning and improvement in team performance. Instructor-led (IL) debriefing is considered the gold standard but is resource-intensive and may not be feasible in settings with limited faculty availability. Peer-led (PL) debriefing offers a potentially cost-effective alternative; however, its impact on debriefing quality, interprofessional competencies and professional identity in Sim-IPE remains underexplored. This study aims to compare PL and IL debriefing in terms of perceived quality and impact on interprofessional outcomes. Methods and analysis This manuscript reports a prospectively registered protocol for a single-centre, parallel-group, non-inferiority randomised controlled trial to be conducted at Qatar University Simulation Centre (Tamayuz). The trial consists of two arms: an IL debriefing arm (control) and a PL debriefing arm (intervention). A total of 120 students will undergo a comprehensive simulation experience, including pre-briefing and simulation, followed by random assignment to one of the debriefing arms. Outcome measures will include the Debriefing Assessment for Simulation in Healthcare Scale, Satisfaction with Simulation Experience tool, Modified McMaster Ottawa Scale for Teams and Extended Professional Identity Scale. At the time of the original submission, participant recruitment had not yet commenced. Ethics and dissemination This study was approved by the Institutional Review Board of Qatar University (QU-IRB 237/2025-EA). All participants in this study will provide informed consent prior to participation in the study. Findings of this study will be submitted to peer-reviewed journals and may be presented at conferences. Trial registration This study is prospectively registered on the International Standard Randomised Controlled Trial Number registry, a recognised clinical trial registry, prior to participant enrolment. Trial registration number ISRCTN52780669 .
