Background: Early identification of trauma patients who need specialized healthcare resources may facilitate goal-directed resuscitation and effective secondary triage.
Objective: To estimate associations between Denver Emergency Department (ED) Trauma Organ Failure (TOF) Score and healthcare resource utilization.
Methods: Retrospective study of adult trauma patients at Denver Health Medical Center. The outcome was resource utilization including: intensive care unit (ICU) length of stay (LOS), hospital LOS, procedures, and costs. Multivariable regression analyses were used to estimate associations between moderate- or high-risk patients, as determined by the Denver ED TOF Score, and healthcare resource utilization.
Results: We included 3000 patients with a median age of 42 (IQR 27-56) years, 71% male, median injury severity score 9 (IQR 5-16), and 83% blunt mechanism. Among the cohort, 1379 patients (46%) were admitted to the ICU and 122 (4%) died. The adjusted relative risk for high- and moderate-risk as compared to low risk for number of procedures performed was 2.31 (95% CI 2.07-2.57) and 1.80 (95% CI 1.59-2.03) respectively; ICU LOS was 2.87 (95% CI 2.70-3.05) and 1.71 (95% CI 1.60-1.83) respectively; hospital LOS was 3.33 (95% CI 3.21-3.45) and 1.97 (95% CI 1.90-2.05) respectively. The adjusted geometric mean for high-, moderate-, and low-risk for costs was $48,881 (95% CI $43,799-$54,552), $27,890 (95% CI $25,460-$30,551), and $12,983 (95% CI $12,493-$13,492), respectively.
Conclusions: The Denver ED TOF Score predicts healthcare resource utilization, and is a useful bedside tool to identify patients early after injury that are likely to require significant healthcare resources and specialized trauma care.
