Traumatic Brain Injury Under Triage Risk: A Rural Trauma System Experience

Abstract

Background The process of interfacility transfer may cause a delay in the necessary medical treatment, which could lead to poor outcomes and increased mortality rates. The ACS-COT considers an acceptable under triage rate of <5%. The aim of this research was to identify the likelihood of under triage among transferred-in traumatic brain injury (TBI) patients. Methods This is a single-center study of Trauma Registry data, from July 1, 2016, to October 31, 2021. The inclusion criteria were based upon age (≥40 years), ICD10 diagnosis of TBI, and interfacility transfer. Under triage using the Cribari matrix method was the dependent variable. A logistic regression was performed to identify additional predictor variables on the likelihood that an adult TBI trauma patient experienced under triage. Results 878 patients were included in the analysis; 168 (19%) experienced an under triage. The logistic regression model was statistically significant (N = 837, P < .01). In addition, several significant increases in odds for under triage were identified, which included increasing injury severity score (ISS; OR 1.40, P < .01), increasing AIS head region (OR 6.19, P < .01), and personality disorders (OR 3.61, P = .02). In addition, a reduction in odds in TBI adult trauma under triage is the comorbidity of anticoagulant therapy (OR .25, P < .01). Conclusions The likelihood of under triage in the adult TBI trauma population is associated with increasing AIS head injuries and increasing ISS and among those with mental health comorbidities. This evidence and additional protective factors, such as patients on anticoagulant therapy, may aid in education and outreach efforts to reduce under triage among the regional referring centers.
