![]() This analysis also employed multiple logistic regression and adjustment for centre effect. ![]() These were patients receiving either HEMS, GEMS with a Medical Emergency Response Incident Team (MERIT) or GEMS with standard crew taken to a TU but requiring time critical interventions (transferred to MTC within 48 h or died within 4 h). Firstly, all patients directly admitted to MTCs with a recorded prehospital time (n = 29,371) were compared by mode of arrival with HEMS or ground emergency medical services (GEMS) using logistic regression, propensity score matching and sensitivity analysis with random intercept modelling for centre effects.Ī second analysis compared three similar patient cohorts admitted to both MTCs and TUs (n = 17,682). Two methods of analyses were employed to attempt to control for confounders. Main outcome measures: The main outcome measure was odds of mortality at 30 days post injury. Participants: A total of 116,258 patients were identified with known outcomes and grouped according to mode of arrival to hospital. Setting: All data from trauma units (TUs) and major trauma centres (MTCs) in England were examined from January 2012 to March 2015. Objectives: To establish the true impact of Helicopter Emergency Medical Services (HEMS) in England on survival for patients with major trauma.ĭesign: As randomized controlled trials are not feasible for this study, a comparative cohort design was employed using data prospectively collected from the TARN national trauma registry. ![]()
