The aim of this study was to compare the ease and accuracy of measuring the surface area of a severe burn through the use of a mobile software application (BurnMed) to the traditional method of assessment, the Lund and Browder chart. BurnMed calculates the surface area of a burn by enabling the user to first manipulate a three-dimensional model on a mobile device and then by touching the model at the locations representing the patient's injury. The surface area of the burn is calculated in real time. Using a cohort of 18 first-year medical students with no experience in burn care, the surface area of a simulated burn on a mannequin was made using BurnMed and compared to estimates derived from the Lund and Browder chart. At the completion of this study, students were asked to complete a questionnaire designed to assess the ease of use of BurnMed. Users were able to easily and accurately measure the surface area of a simulated burn using the BurnMed application. In addition, there was less variability in surface area measurements with the application compared to the results obtained using the Lund and Browder chart. Users also reported that BurnMed was easier to use than the Lund and Browder chart. A software application, BurnMed, has been developed for a mobile device that easily and accurately determines the surface area of a burn. This system uses a three-dimensional model that can be rotated, enlarged, and transposed by the health care provider to easily determine the extent of a burn. Results show that the variability of measurements using BurnMed is lower than the measurements obtained using the Lund and Browder chart. BurnMed is available at no charge in the Apple™ Store.
本研究的目的是比较使用移动软件应用程序（BurnMed）测量严重烧伤表面积的便捷性和准确性与传统评估方法——伦德和布劳德图表。BurnMed通过让用户首先在移动设备上操作三维模型，然后在代表患者受伤部位触摸该模型来计算烧伤的表面积。烧伤表面积实时计算得出。以18名无烧伤护理经验的一年级医学生为一组，使用BurnMed测量人体模型上模拟烧伤的表面积，并与根据伦德和布劳德图表得出的估计值进行比较。在本研究结束时，要求学生完成一份旨在评估BurnMed易用性的问卷。用户能够使用BurnMed应用程序轻松、准确地测量模拟烧伤的表面积。此外，与使用伦德和布劳德图表获得的结果相比，该应用程序测量的表面积变异性更小。用户还报告说，BurnMed比伦德和布劳德图表更易于使用。已为移动设备开发了一款软件应用程序BurnMed，它能轻松、准确地确定烧伤的表面积。该系统使用一个三维模型，医疗保健人员可以对其进行旋转、放大和转换，以轻松确定烧伤的范围。结果表明，使用BurnMed测量的变异性低于使用伦德和布劳德图表测量的变异性。BurnMed在苹果™ 商店免费提供。
