| 1 | The impact of emergency department length of stay on the outcomes of trauma patients requiring hospitalization: a retrospective observational study显示文摘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). 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]=4.081, 95%CI: 2.364–7.045), head injury(OR=3.920, 95%CI: 2.413–6.368), blood transfusion(OR=2.773, 95%CI: 1.668–4.609), SI(OR=2.132, 95%CI: 1.364–3.332), ISS(OR=1.077, 95%CI: 1.057–1.096), and age(OR=1.040, 95%CI: 1.026–1.054). CONCLUSIONS: Patients with shorter EDLOS had different baseline characteristics and hospital outcomes compared with patients with longer EDLOS. Patients with prolonged EDLOS had better outcomes;however, the burden of prolonged boarding in the ED needs further elaboration. | Ahmed Faidh Ramzee Ayman El-Menyar Mohammad Asim Ahad Kanbar Khalid Ahmed Bahaa Daoud Saji Mathradikkal Ahmad Kloub Hassan Al-Thani Sandro Rizoli | 2023 | World Journal of Emergency Medicine2023，14，2： | 1 |
