BACKGROUND:We aimed to explore the impact of the emergency department length of stay (EDLOS) on the outcome of trauma patients.
METHODS:A retrospective study was conducted on all trauma patients requiring hospitalization between 2015 and 2019. Patients were categorized into 4 groups based on the EDLOS (<4 h, 4-12 h,12-24 h and >24 h). Data were analyzed using Chi-square test (categorical variables), Student's t-test (continuous variables), correlation coefficient, analysis of variance and multivariate logistic regression analysis for identifying predictors of short EDLOS and hospital mortality.
RESULTS:The study involved 7,026 patients with a mean age of 32.1±15.6 years. Onefifth of patients had a short EDLOS (<4 h) and had higher level trauma team T1 activation (TTA-1), higher Injury Severity Score (ISS), higher shock index (SI), and more head injuries than the other groups (P=0.001). Patients with an EDLOS >24 h were older (P=0.001) and had more comorbidities (P=0.001) and fewer deaths (P=0.001). EDLOS was significantly correlated with ISS (r=-0.047), Glasgow Coma Scale (GCS) (r=0.087), and Revised Trauma Score (r=0.102). Multivariate regression analysis showed that the predictors of short EDLOS were female gender, GCS, SI, hemoglobin level, ISS, and blood transfusion. The predictors of mortality were TTA-1 (odds ratio [OR]=4.
