Background:triage trauma scores are utilised to determine patient disposition,interventions and prognostication in the care of trauma *** rate variability(HRV)and heart rate complexity(HRC)reflect the autonomic nervous system and are derived from electrocardiogram(ECG)*** this study,we aimed to develop a model incorporating HRV and HRC,to predict the need for life-saving interventions(LSI)in trauma patients,within 24 h of emergency department ***:We included adult trauma patients(≥18 years of age)presenting at the emergency department of Singapore General Hospital between October 2014 and October *** excluded patients who had non-sinus rhythms and larger proportions of artefacts and/or ectopics in ECG *** obtained patient demographics,laboratory results,vital signs and outcomes from electronic health *** conducted univariate and multivariate analyses for predictive model ***:Two hundred and twenty-five patients met inclusion criteria,in which 49 patients required *** LSI group had a higher proportion of deaths(10,20.41%vs 1,0.57%,ptriage trauma scores and selected vital signs in predicting the need for LSIs but needs to be validated in larger patient populations.
