40 Wildfire Burn Victims: A Unique Population

Abstract

Abstract Introduction In the past ten years, wildfires have burned an average of 6.8 million acres annually. The frequency of wildfires is expected to increase with climate change. Wildfire burn victims have not been previously well characterized in the literature. As we prepare for more wildfires it is necessary to target populations at risk for sustaining burns with prevention efforts and to prepare hospital systems to meet these patients’ needs. Methods A retrospective review of patients admitted to a burn center between 2016 and 2019 was performed. Patients who were admitted after sustaining a burn attributable to wildfires were identified from the burn center database. Controls were matched to wildfire burn patients by age, gender and total body surface area of burn. The primary outcome was mortality. Secondary outcomes included number of operations, length of stay (LOS), intensive care unit (ICU) LOS, development of wound infections and pneumonia, wound culture microbiology. Results A total of 16 patients who had sustained burns in wildfires were identified and matched with 32 controls. There was no difference in mortality (19% wildfire vs. 9% non, p=0.386), LOS (18 days wildfire vs. 15 days non-wildfire, p=0.406), ICU LOS (17 days wildfire vs. 11 days non-wildfire, p=0.991) and number of skin grafts (1 wildfire vs. 0.5 non-wildfire, p=0.519). Patients who had sustained burns in a wildfire trended towards higher rates of pneumonia (31% wildfire vs. 13% non-wildfire, p=0.117), and higher rates of wound infection (31% wildfire vs. 19% non-wildfire, p=0.361). On evaluation of wound cultures for the 5 wildfire patients and the 7 non-wildfire patients who developed wound infections, more patients who sustained burns in wildfires had gram positive bacteria cultured from their wounds (100% wildfire vs. 29% non-wildfire, p=0.027). Patients who had sustained burns in wildfires trended towards increased likelihood of readmission (23% wildfire vs. 3% non-wildfire, p=0.080). Conclusions Patients who sustain burns in wildfires are likely at increased risk of readmission, of developing pneumonia and of developing gram-positive wound infections. Interventions for these patients should focus on pneumonia prevention and assistance with wound care after discharge.
