Prevalence and Factors Predicting Preventable Trauma Induced Mortality

Introduction: Trauma is one of the most common causes of morbidity and mortality worldwide. Since the definition of preventable death has been described many studies, like current one, were conducted to evaluate this issue.Materials and Methods: This cohort retrospective study investigated archived medical files of trauma victims from 2017 to 2020 in a referral single-center trauma hospital. Registered demographic data, vital signs, Glasgow coma scale (GCS), timing of trauma and death, executed interventions, type and mechanism of trauma in addition to time errors, clinical mismanagements and missed injuries were extracted. Injury severity score (ISS), revised trauma score (RTS) and probability of survival (Ps) based on TRISS method for each case were calculated. Eventually preventable and non-preventable death groups were compared.Results: Finally from the all 413 trauma victims 246(54.9%) files were enrolled. Victims aged from 18 to 95 years. Of all 189(76.8%) were males. Analysis manifested 135(54.9%) of all deaths were potentially and 2(0.08%) were certainly preventable; while the other 49.1% were non-preventable for expiration(p=0.001). Data showed that from all variables systolic blood pressure (SBP) ≥80mmHg, respiratory rate (RR) ≥20 per minute, GCS ≥8, higher RTS, road traffic accidents and control of external bleeding were contribute to prediction of preventable trauma related mortality.Conclusion: This study implied on frequency of trauma related preventable death was regionally high and associated factors that could be lessen the number of these mortalities including of SBP, RR, GCS, RTS, mechanism of trauma and external bleeding of trauma patients should be paid more attention.Trial registration: Retrospectively registered.
