Mortality Rate of Trauma Patients with ESI Triage Level 1-2 Who Underwent Computerized Tomography-PANSCAN versus Conventional Computerized Tomography Scan.

Objective: The treatment of severe trauma patients requires a fast and accurate method to diagnose life-threatening conditions. Computerized tomography (CT)-PANSCAN has been widely used for the last 20 years to diagnose many patients in critical condition. However, no research has been performed into the efficacy of CT-PANSCAN. This research aims to compare the mortality rate of trauma patients who underwent CT-PANSCAN versus conventional CT scan.

Methods: This retrospective cohort study enrolled patients who were at triage ESI level 1-2 in the emergency department of Ramathibodi Hospital from January 2013 to December 2018 and analyzed the mortality rate between those who underwent CT-PANSCAN and conventional CT scan.

Results: The study enrolled 123 trauma patients; 61 patients underwent CT-PANSCAN, whereas 62 patients underwent conventional CT scan. There were 1 and 7 patients who expired in the CT-PANSCAN and conventional CT scan groups, respectively. After multivariate regression analysis, the result revealed that patients who underwent CT-PANSCAN had a lower mortality rate (adjusted odds ratio = 0.023; p-value = 0.018; 95% CI 0.001-0.518).

Conclusion: Undergoing a CT-PANSCAN can reduce the mortality rate in trauma patients, especially in ESI level 1, 2 traumatic patients, and CT-PANSCAN available facilities.
