Abstract
BACKGROUND: Physician-based prehospital teams provide advanced critical care services in the UK (eg, prehospital anaesthesia). The last review of such teams in 2009, which included England, Wales and Northern Ireland, reported only one physician-based prehospital team available 24/7. Helicopter Emergency Medical Services (HEMS) across the UK offer paid physician-based teams, while other organisations may provide physician-based teams on a voluntary ad hoc basis. The primary aim of this study was to determine if access to a physician-based HEMS team has changed in the past 12 years. METHODS: An online survey was distributed to all UK HEMS organisations in January 2024. The primary outcome measure was the number of physician-based teams operated by HEMS in 2024 and the operational hours of such teams. Secondary outcomes included interventions offered by HEMS teams and any additional medical teams offered (eg, paramedic only). RESULTS: All 21 HEMS responded. The number of potentially available physician-based HEMS teams has increased from 11 in England, Wales and Northern Ireland in 2009 to 28 in 2024, with two services in Scotland (total=30). HEMS providing consistent 24/7 physician-based prehospital teams increased from one (5.9%) in 2009 to 11 (52.4%) in 2024. The East of England has the highest 24/7 availability, with Northern Ireland, South West England and Northern England the least. Within physician-based teams, variation remains in advanced interventions available-for example, 19 services (90.4%) offer blood transfusion while only one (4.7%) offers resuscitative balloon occlusion of the aorta. Only one service is completely government funded; the others are funded by charity alone or a combination of charity and government sources. CONCLUSION: Both geographical and temporal variations in access to a physician-based HEMS remain across the UK, although there has been improvement since 2009. However, within this provision, variation exists in terms of interventions provided such as the provision of blood products.
