Background: Trauma is the leading cause of mortality in children. Burn injury involves intensive resources, especially in pediatric patients. We hypothesized that among pediatric trauma patients, combined burn-trauma (BT) patients have increased length of stay (LOS) and mortality compared to trauma-only (T) patients. Methods: The Pediatric Trauma Quality Improvement Program (2014-2016) was queried and BT patients were 1:2 propensity-score-matched to T patients based on age, gender, hypotension on admission, injury type and severity. Results: 93 BT patients were matched to 186 T patients. There were no differences in matched characteristics. BT patients had a longer median LOS (4 vs 2 days, p <0.001) with no difference in mortality (1.1% vs 1.1%, p =1.00), intensive care unit (ICU) LOS (3 vs 3 days, p =0.55), or complications including decubitus ulcer (0% vs 1.1%, p =0.32), deep vein thrombosis (0% vs 0.5%, p =0.48), extremity compartment syndrome (1.1% vs 0%, p =0.16), and urinary tract infection (1.1% vs 1.1%, p =1.00). Conclusion: Pediatric BT patients had twice the LOS compared to a matched group of pediatric T patients. There was no difference between the cohorts in ICU LOS, complications or mortality rate. When evaluating risk-stratified quality metrics such as LOS, concomitant burn injury should be incorporated. (c) 2020 Elsevier Ltd and ISBI. All rights reserved.
