Geospatial Analysis of Pediatric Burns Reveals Opportunities for Injury Prevention.

Abstract

Background: Geospatial analysis is useful for identifying hot spots for preventable injuries and for informing prevention efforts. We hypothesize that specific populations of children in South Florida are at increased risk of burn injury.

Methods: We used a regional burn center registry to geocode burn cases treated from July 2013 to December 2022 for patients <18 years. Spatial analysis was utilized to identify high-density areas and potential spatial clusters of patients living in Palm Beach, Broward, and Miami-Dade Counties. Sociodemographic factors, burn etiology, and physiologic characteristics were analyzed using geospatial and statistical analyses.

Results: 689 patients (58% male, median age 2 [1-8] years) were identified. The annual incidence of burns was 5.5 per 100,000 children. There was no seasonal variation in injury patterns. Most patients were Black (51%) and non-Hispanic (73%). Scald burns (72%) represented the most common etiology, followed by flame (10%) and contact with hot objects (9%). Most patients (58%) required inpatient admission. Scald and contact burns occurred in younger patients compared to other mechanisms (median [IQR] age: 2 [1-6] vs. 8 [4-12] years, p < 0.001). Race, ethnicity, and insurance status were not associated with inpatient admission (all p > 0.05). Overall, there was a higher rate of pediatric burn injuries affecting Black residents, with a paucity of injuries in predominately high-income areas.

Conclusions: A disproportionate amount of pediatric burn injuries occur in low-income and predominantly Black neighborhoods. Additionally, scald and contact burns are a target for injury prevention in South Florida. These data may inform public health implementation to reduce morbidity in vulnerable populations.

Level of evidence: Level III.

Type of study: Retrospective comparative study.
