Abstract Incident reporting in Emergency Medical Services (EMS) is vital for enhancing patient safety and system performance, but time constraints often impede efficient documentation. Hamad Corporation Ambulance Service Group (HMCASG) implemented a streamlined “Occurrence, Variance, Accident” (OVA) to address these challenges. This study evaluated the effectiveness of this reducing incident report completion time. A “Lean” approach was used streamline process. Four‐hundred eighty‐two OVA...
