Epidemiology and trend of US pediatric burn hospitalizations, 2003-2016.

BACKGROUND: Thermal injury is a leading cause of unintentional pediatric trauma morbidity and mortality.

METHODS: This retrospective analysis of the 2003-2016 Kids' Inpatient Database (KID) included children <18 years old with a burn principal diagnosis. The objectives were to describe the trend of US pediatric burn hospital admissions and the patient and hospital characteristics of admitted children in 2016. The trends (2003-2012) and (2012-2016) were evaluated separately due to the 2015 implementation of International Classification of Diseases, Tenth Revision (ICD-10).

RESULTS: The population rate of pediatric burn admissions decreased by 4.6% from 2003 to 2012, but the proportion of admissions to hospitals with burn pediatric patient volumes≥100 increased by 63.9%. The overall mortality rate of hospitalized burn patients decreased by 48.1%. Median length of stay increased slightly for patients with a burn ≥20% total body surface area (TBSA) but decreased for patients with TBSA burn <20%. From 2012 to 2016, the population rate decreased by 13.4%. In 2016, an estimated 8160 children were admitted with a burn principal diagnosis, and 41.4% transferred in from other facilities. Children age 1-4 years were the most commonly admitted age group (49.7%). Patients with ≥20% TBSA burns accounted for 7.8% of admissions (95% confidence interval [CI]: 5.1-10.4%). Burn-related complications were documented in 5.9% of admissions (95% CI: 4.6-7.1%).

CONCLUSION: Pediatric burn hospitalizations and burn-related mortality have decreased over time. The increases in transfers and admissions to hospitals with high pediatric burn volumes suggest increasing regionalization of care.
