We reported the efficacy of soft silicone multilayered foam dressings in preventing intraoperatively acquired pressure injuries (IAPIs) in the prone position using a Relton-Hall frame (BOSS trial). The aim of this study was to clarify the incidence and extract the risk factors for IAPIs in cases in which polyurethane film dressing was used against IAPIs before the BOSS trial period. This study conducted as a retrospective dual-center cohort study between August 2014 and Jun 2015 using the medical records in the operating room. The incidence of IAPIs that developed within 24 hours after surgery was 7.1% (7/99). The multivariate logistic regression analysis revealed that body mass index (BMI) (P = .0016, odds ratio [OR]: 1.22, 95% confidence interval (CI) 1.08-1.4) and length of surgery (P < .0001, OR 2.47, 95% CI 1.86-3.51) were independently associated with the development of IAPIs. Since high BMI was not extracted in BOSS trial, we conclude that the application of soft silicone multilayer foam dressings is important for preventing the development of IAPIs in patients with high BMI values.
