Prospective with historical control, case-matched cohort study of the tertiary survey beneficial in critically severe trauma patients

Abstract

Background The tertiary survey is an evaluation process conducted after the primary and secondary surveys. It aims to identify missed injuries. This research aims to study the benefits of tertiary surveys in severely traumatized patients. Methods This prospective with historical control, case-matched cohort was conducted on critically-ill trauma patients who were admitted to the surgical intensive care unit (SICU) of Thammasat University Hospital. The study compared the period before and after the implementation of the tertiary survey. Tertiary survey record form was used in all severely traumatized patients with Injury Severity Score (ISS) > 15 within the first 24 hours and before discharge from SICU between August 2022 and February 2023. The comparison data were retrieved from electronic medical records of patients admitted to SICU with ISS > 15 between April 2020 and July 2022. Results We identified 55 type II missed injuries in 39 of 100 cases prior to implementation and 1 type II missed injury after implementation. Type II missed injury decreased from 31% to 4%, and the missed injury detection rate was 56% after implementing the tertiary survey. However, there is no statistically significant difference in morbidity and mortality rates from missed injuries before and after implementation. Conclusions Using tertiary surveys can reduce missed injury rates and increase missed injury detection rates. This research highlights the importance of implementing tertiary surveys as a routine part of trauma evaluation to improve patient care. However, there is no effect on the outcomes, which may require more sample size. Clinical Trials Registry (reference number TCTR20230625001).
