Abstract

OBJECTIVE: To assess the effect of the development of an experimental trauma centre and regional trauma system on the survival of patients with major trauma. DESIGN: Controlled before and after study examining outcomes between 1990 and 1993, spanning the introduction of the system in 1991-2. SETTING: Trauma centre in North Staffordshire Royal Infirmary and five associated district general hospitals in the North West Midlands regional trauma system, and two control regions in Lancashire and Humberside. SUBJECTS: All trauma patients taken by the ambulance services serving the regions or arriving other than by ambulance with injury severity scores > 15, whether or not they had vital signs on arrival at hospital. MAIN OUTCOME MEASURES: Survival rates standardised for age, severity of injury, and revised trauma score. RESULTS: In 1990, 33% of major trauma patients in the experimental region were taken to the trauma centre, and by 1993 this had risen to only 39%. Crude death rates changed by the same amount in the control regions (46.5% in 1990-1 to 44.4% in 1992-3) as in the experimental region (44.8% to 41.3%). After standardisation, the estimated change in the probability of dying in the experimental region compared with the control regions was -0.8% per year (95% confidence interval -3.6% to 2.2%); for out of hours care, the change was 1.6% per year (-2.3% to 5.6%), and, for multiply injured patients, the change was -1.6% (-6.1% to 2.6%). CONCLUSION: Any reductions in mortality from regionalising major trauma care in shire areas of England would probably be modest compared with reports from the United States.
