Motorsport medical preparedness in compact urban environment: Lessons from Hong Kong in 5 years

Background: Motorsport events necessitate medical services from first aid to intensive care due to high-velocity impacts and fire hazards. Urban circuits pose unique logistical challenges. We report the adaptations, operational experience and lessons learnt from four international Fédération Internationale de l’Automobile (FIA)-tier motorsport events in Hong Kong. Methods: This mixed-methods observational study used the Data Reporting, Evaluation, and Analysis for Mass-Gathering Medicine Model, analysing medical usage rates, stakeholder interviews and protocol observations. Data from anonymised patient records and debrief notes were descriptively analysed. Key stakeholders, including the Chief Medical Officer and FIA delegates, were interviewed. Results: Between 2017 and 2023, Hong Kong hosted four FIA-level events on temporary street circuits. Planning evolved from reactive, ad hoc collaborations to proactive, simulation-driven multi-agency strategies. Service provision improved with more advanced life support, refined medical roles, and structured communication. Across the events, 87% of presentations were minor. Patient presentation rates ranged 0.416–0.83 per 1000 attendees, and no competitors required hospital transfer from on-track crashes, highlighting the high-acuity, low-occurrence nature of incidents. Key measures included a Unified Communication Channel, a Joint Agency Command Centre, and specialized extrication training. These measures enhanced situational awareness and streamlined resource allocation, providing effective for managing complex motorsport events in urban setting. Conclusions: Medical preparedness for urban circuits requires clear command, centralised communication, risk-based resource allocation, and targeted training. The Hong Kong experience offers transferable strategies for infrequent, high-profile city events. Prospective, comparative studies across global events are recommended to further improve practices and ensure safety for all participants.
