AbstractThe present study aimed to investigate the appropriate timing of excision or skin grafting of burn wounds in patients with severe burns. We retrospectively analyzed data from the Diagnosis Procedure Combination Database, a nationwide inpatient database in Japan. Patients with severe burns (burn index ≥10) who underwent excision or skin grafting within 7 days from September 2010 to March 2019 were included. We defined the early surgery group as patients who underwent excision or skin grafting within 2 days of admission and the delayed surgery group as those who underwent surgery within 3-7 days of admission. Propensity score matching was used to compare the in-hospital mortality between the two groups, yielding a cohort of 389 pairs. A total of 2362 eligible patients were categorized into the early surgery group (n = 626) and delayed surgery group (n = 1736). The overall in-hospital mortality was 19.6%. In-hospital mortality did not differ significantly between the early surgery (15.9%) and the delayed surgery groups (17.2%; p = 0.70). These results suggest that excision or skin grafting within 2 days of admission was not associated with improved in-hospital mortality compared with surgery thereafter for patients with severe burns.Copyright © 2023 The Authors.
