BACKGROUND: Routine clinical debriefings (RCDs) have been shown to improve communication, team reflexivity, and safety in clinical settings. When combined with incident reports (IRs), RCDs offer a potential tool for enhancing quality improvement frameworks. This study aimed to identify and compare healthcare safety-related information captured through RCDs and IRs in a Belgian emergency department operating across two distinct facilities. METHODS: This study employed a quasi-mixed-method design with a monostrand conversion approach. Information was collected from 90 RCDs and 263 IRs. Data were analyzed using two frameworks: the World Health Organization's Incident Report Classification Grid and the Debriefing and Organizational Lessons Learned Grid. RESULTS: The findings revealed significant differences in the types of information captured by RCDs and IRs. RCDs predominantly highlighted teamwork, internal organization, and procedural issues, while IRs focused more on care processes, patient concerns, and patient flow. These complementary insights demonstrate the value of integrating RCDs and IRs to create a comprehensive understanding of patient and clinician safety. CONCLUSIONS: This study highlights the complementary nature of RCDs and IRs in addressing healthcare safety. RCDs foster team reflexivity and promote open discussions about systemic challenges, directly improving team cohesion, resilience, and learning. Combining RCDs and IRs provides actionable insights for enhancing safety and driving organizational improvements.
