The association between neighborhood disadvantage and patient-reported outcomes in burn survivors.

ABSTRACT

BACKGROUND: Burns can cause long-term complications including pain and poor physical function. While neighborhood disadvantage is associated with burn severity, its effect on long-term complications has not been investigated. We hypothesized that patients from areas of higher area of deprivation index (ADI) will report poorer long-term outcomes. METHODS: We linked patient data from the Burn Model System with ADI state decile (1 = least, 10 = most disadvantaged) using year and residence at time of injury. We performed bivariate analyses to identify associations between ADI and patient and burn characteristics and multivariate regressions to determine whether ADI was associated with PROMIS-29 pain and physical function 6- and 24-months post-burn. RESULTS: We included 780 patients; 69 % male, median age = 46 years, median ADI = 6, and median TBSA = 8 %. Multivariate regressions adjusting for TBSA, race, age, sex, anxiety, depression, and pain interference demonstrated that higher ADI was a significant predictor of higher pain intensity 6- (p = 0.001) and 24-months (p = 0.037) post-burn but not worse physical function 24-months post-burn (p = 0.089). CONCLUSIONS: Higher neighborhood disadvantage was associated with higher long-term pain intensity post-burn. This study highlights the importance of socioeconomic factors that may impact long-term outcomes and the use of aggregate markers to identify patients at risk for worse outcomes.
