IntroductionPatients with major burns can undergo temporary coverage while skin graft donor sites heal, where dermal templates have an emerging role. The aim of this study was to evaluate the clinical outcomes and resource utilisation in patients with major burns treated with a bilayer biodegradable synthetic matrix (NovoSorb BTM).MethodThis retrospective cohort study included patients admitted to the Royal Brisbane and Women's Hospital Adult Burn Unit with burns to at least 40 % TBSA who survived their acute admission. Patients treated from July 2017 to June 2022 with BTM were compared with patients with similar injuries treated using cadaveric allograft as temporising full thickness wound coverage between January 2013 and June 2017. Outcomes measures included number of operations, total operative time, hospital and intensive care unit (ICU) length of stay (LOS), cadaveric allograft and BTM use, and blood product use. Unadjusted comparisons were made with Wilcoxon Rank-Sum tests and Fisher's exact tests. Multivariate linear regression was used to adjust for the effect of TBSA on each outcome.ResultsFifty-five patients were included (78 % male), 22 of whom were treated with BTM. We found no significant differences in age, sex, or TBSA between groups. One patient had half of the BTM removed due to infection and replaced with allograft. Patients treated with BTM had significantly less operative theatre time (median 1361.5 min [BTM] vs 1768 min [no BTM], P = 0.044). Number of operations, allograft use, hospital and ICU LOS, and blood product use were similar between groups. Adjusted models accounting for TBSA supported unadjusted models.ConclusionResource utilisation and clinical outcomes were similar in patients with at least 40 % TBSA treated with BTM and those who were treated with allograft before the introduction of BTM. Patients treated with BTM had significantly less total operative time and no difference in number of operations, allograft use and ICU LOS.Copyright © 2023 The Authors. Published by Elsevier Ltd..
