Efficacy of Reusable Rubber Moulage on Mannequin Versus Conventional Method for Burn Size Estimation

Abstract

Background: Burn size estimation is crucial to burn fluid resuscitation. Therefore, training and practice to improve the accuracy of burn size estimation is important. Using reusable rubber moulage (RRM), the newly developed equipment to cooperating with simulation might help improve the accuracy of burn size estimation compared to conventional picture illustration. Objectives: To compare the accuracy of burn size estimation in simulation between picture illustration and RRM application, and to validate the face and content validity of RRM. Methods: Medical students, ER residents, EP staff, and paramedics were recruited and randomized into 2 groups. Each group completed 2 different burn pattern stations consisting of one RRM-decorated mannequin station and one picture illustration station. The estimation of total body surface area (TBSA) percentage was statistically analyzed to determine the difference between the 2 methods. Face and content validation were analyzed by a Likert scale. Results: A total of 70 participants were recruited. The means of total %TBSA of pattern 1 from RRM and picture illustration were 42.29% and 41.24% (P = .61), respectively. The means of pattern 2%TBSA estimation were 41.24% and 42.65% (P = .34), respectively. Participants rated RRM quality by Likert scale with means score more than 4 out of 5 in all questions. Written comments showed a preference toward RRM. Conclusions: There were no significant %TBSA differences between RRM decorated mannequin and picture illustration in terms of %TBSA. However, participants were satisfied with RRM quality and preferred RRM decorated mannequin.
