Zusammenfassung:Abstract Aim This study aimed to determine factors linked to hypothermia ( 15. Demographic, injury, environmental, care and clinical status factors were considered. Results A total of 2182 patients were included; 124 (5.7%) had hypothermia on admission to the definitive care hospital, while a further 156 (7.1%) developed hypothermia during hospitalisation. Factors associated with hypothermia on admission included winter, direct admission to a definitive care hospital, an ISS ≥ 40, a Glasgow Coma Scale of 3 or ventilated and sedated, and hypotension on admission. Hypothermia on admission to the definitive care hospital was an independent predictor of mortality (odds ratio [OR] = 4.05; 95% confidence interval [CI] 2.26–7.24) and hospital length of stay (incidence rate ratio [IRR] = 1.22; 95% CI 1.03–1.43). Hypothermia during definitive care hospitalisation was independently associated with mortality (OR = 2.52; 95% CI 1.52–4.17), intensive care admission (OR = 1.73; 95% CI 1.20–2.93) and hospital length of stay (IRR = 1.18; 95% CI 1.02–1.36). Conclusions Trauma patients in a predominantly sub-tropical climate are at risk of accidental and endogenous hypothermia, with associated higher mortality and care requirements. Prevention of hypothermia is important for all severely injured patients.
