30-day survival and injury severity in traffic accidents in Iran: A mixed-method study protocol

This mixed-methods study will be conducted in three phases: 1. Phase 1 (Quantitative): A prospective cohort study will investigate the relationship between injury severity (as measured by scales such as ISS)and 30-day survival rates. 2. Phase 2 (Qualitative): Purposive sampling will be used to conduct semi-structured interviews with stakeholders (victims, families, EMTs, healthcare providers, etc.). Qualitative data will be analyzed via inductive content analysis (Hsieh & Shannon approach) to identify challenges and solutions in traffic accident management. 3. Phase 3 (Integration): Findings from Phases 1 and 2 will be finalized and presented to policymakers, managers, and experts. The Delphi method will be used to prioritize challenges/solutions and finalize evidence-based recommendations.Results will be disseminated through: Peer-reviewed publications in reputable journals. Policy briefs tailored for officials to improve traffic accident management.
