58 The Homelessness Crisis and Burn Injuries: A Cohort Study

The United States is facing a growing homelessness crisis. We characterize the demographics and outcomes of homeless patients who sustain burn injury and compare them to a cohort of domiciled patients. A retrospective cohort study was performed at the Los Angeles County + University of Southern California Regional Burn Center for consecutive acute burn admissions in adults from June 1, 2015, to December 31, 2018. Patients were categorized as either domiciled or homeless at the time of their injury. Prevalence rates were estimated using data from the regional homeless count. From 881 admissions, 751 (85%) had stable housing and 130 (15%) were homeless. The rate of burn injury requiring hospitalization for homeless adults was estimated at 88 per 100,000 persons. Homeless patients had a significantly larger median burn size (7 vs 5%, P <.05) and a greater rate of flame burns (68 vs 42%, P <.001). For the homeless, rates of assault and self-inflicted injury were 4- (18 vs 4%, P <.001) and 2-fold higher (9 vs 4%, P <.001), respectively. Homeless patients had higher rates of mental illness (32 vs 12%, P <.001) and substance abuse (88 vs 22%, P <.001), and were less likely to follow-up as outpatients (54 vs 87%, P <.001). There was no difference in mortality. Homeless patients had a longer median length of stay (LOS; 11 vs 7 days, P <.001) without significant differences in LOS per percentage TBSA. Homeless individuals should be considered a high-risk population for burn injury. This distinction serves as a call to action for the development of burn prevention strategies.
