IntroductionLittle is known about the costs of treating burn patients after a mass casualty event. A devastating Color Dust explosion that injured 499 patients occurred on June 27, 2015 in Taiwan. This study was performed to investigate the economic effects of treating burn patients at a single medical center after an explosion disaster.MethodsA detailed retrospective analysis on 48 patient expense records at Chang Gung Memorial Hospital after the Color Dust explosion was performed. Data were collected during the acute treatment period between June 27, 2015 and September 30, 2015. The distribution of cost drivers for the entire patient cohort (n=48), patients with a percent total body surface area burn (%TBSA)≥50 (n=20), and those with %TBSA <50 (n=28) were analyzed.ResultsThe total cost of 48 burn patients over the acute 3-month time period was $2,440,688, with a mean cost per patient of $50,848 ±36,438. Inpatient ward fees (30%), therapeutic treatment fees (22%), and medication fees (11%) were found to be the three highest cost drivers. The 20 patients with a %TBSA ≥50 consumed $1,559,300 (63.8%) of the total expenses, at an average cost of $77,965±34,226 per patient. The 28 patients with a %TBSA <50 consumed $881,387 (36.1%) of care expenses, at an average cost of $31,478±23,518 per patient.ConclusionsIn response to this mass casualty event, inpatient ward fees represented the largest expense. Hospitals can reduce this fee by ensuring wound dressing and skin substitute materials are regionally stocked and accessible. Medication fees may be higher than expected when treating a mass burn cohort. In preparation for a future event, hospitals should anticipate patients with a %TBSA≥50 will contribute the majority of inpatient expenses.Copyright © 2016 Elsevier Ltd. All rights reserved.
