118 The Clinical and Demographic Predictors Associated with Physical Function in Pediatric Burn Survivors: A Burn Model System National Database Study

Abstract

Abstract Introduction Burns are a common pediatric injury, and severe burns can interfere with a child’s physical function. Rehabilitation for these patients continues to evolve; however, little is known about how clinical and demographic factors affect long-term physical function outcomes. This study will evaluate the association between Patient Reported Outcome Measurement Information System-29 (PROMIS) physical function-mobility subscale scores (PF) and various clinical and demographic factors among pediatric burn survivors. Methods Data were collected from the Burn Model System National Database (1994–2020) and was compiled from five ABA verified burn centers. The data requested included pediatric self-report PROMIS PF scores assessed at 6 months post-burn. A linear regression model was performed with PF total score at 6 months as the dependent variable and total body surface area (TBSA) burned, age, sex, etiology of the burn, length hospital of stay (LOS), and race/ethnicity as independent variables. Results A total of 82 patients between the ages of 8–17 were included in the regression analysis. The mean physical function scores for the participants was 46.2 (SD=11.9), 20.0–57.1 with 50 (SD=10) being the average for the general population. The mean % TBSA burned was 37 (SD=19), 2–90. The regression model revealed an association (n=82; F=7.85; p< 0.001; R2=0.2648) of PF to the predictors LOS (p < 0.001; regression coefficient= -0.18) and White ethnicity compared to Hispanic (p< 0.001; regression coefficient=8.89). Conclusions In this study, pediatric burn patients’ self-reported physical function was associated with ethnicity and hospital stay, with longer hospital stay and Hispanic ethnicity resulting in lower PF.
