Outcomes of Geriatric Burn Patients Presenting to the Trauma Service: How Does Frailty Factor in?

Introduction: Frailty has been known to negatively affect the outcomes of geriatric trauma patients. However, there is a lack of data on the effect of frailty on the outcomes of geriatric trauma patients with concomitant burn injuries. The aim of our study was to compare the outcomes of frail versus nonfrail geriatric trauma patients with concomitant burn injuries. Methods: We performed a retrospective analysis of American College of Surgeons Trauma Quality Improvement Program (2018). We included geriatric (>= 65 y) trauma patients who sustained a concomitant burn injury with >= 10% Total Body Surface Area affected. Patients with body region-specific AIS >= 4 were excluded. Patients were stratified into Frail and Nonfrail, using 5-factor modified Frailty Index. Primary outcomes measured were mor-tality. Secondary outcomes measured were complications, and hospital and intensive care unit (ICU) length of stay (LOS). Multivariable logistic regression was performed to identify independent predictors of mortality.Results: A total of 574 patients were identified, of which 172(30%) were Frail. Mean age was 74 +/- 7 y and median [interquartile range] ISS was 3[1-10]. Overall, the rate of mortality was 23% and median hospital LOS was 14[3-31]. After controlling for potential confounding factors, frailty was not identified as an independent predictor of mortality (adjusted odds ratio:1.059, P = 0.93) and complications (adjusted odds ratio:1.10, P = 0.73). However, frail patients had longer hospital (13: 5.01, P = 0.002) and ICU LOS (13: 2.12, P < 0.001). Conclusions: Among geriatric trauma patients with concomitant burn injuries, frailty is asso-ciated with longer hospital and ICU LOS, and higher rates of thrombotic complications, but not higher mortality or overall complications. Future research should investigate the impact of early assessment of frailty as well as tailored interventions on outcomes in this population.(c) 2023 Elsevier Inc. All rights reserved.
