Predicting factors for major trauma patient mortality analyzed from trauma registry system.

OBJECTIVE We investigated the predictors of mortality in major trauma patients using a trauma registry system database. METHODS Data were obtained from the trauma registry of a level I trauma center for all patients aged ≥18 years admitted to an intensive care unit (ICU) between January 1, 2006 and December 31, 2013. Models were adjusted for patient demographics, injury mechanism, preexisting comorbidity, Glasgow coma scale (GCS), injury severity score (ISS), emergency department (ED) and ICU procedures, surgical procedures, and complications. Multivariate logistic regression analysis was used to determine predictors of mortality and odds ratios of its associated factors. RESULTS In total, 1561 patients met the inclusion criteria. The overall mortality rate was 13.4%. After controlling for all variables in a logistic regression model, the factors associated with increased mortality risk (P   24; GCS score < 8 and 8-12; fall accident; preexisting comorbidity of renal insufficiency; ED cardiopulmonary resuscitation (CPR) procedures; ICU blood transfusion; and cardiovascular, respiratory, digestive system and infection complications. CONCLUSION Our data showed some predictors of patient mortality after major trauma, most of which were determined during the trauma event. Only those treatment complications may be improved when performing the treatment procedures.
