The accurate measurement of diabetic foot ulcer (DFU) wound size is essential as the rate of wound healing is a significant prognostic indicator of the likelihood of complete wound healing. Mobile phone photography is often used for surveillance and to aid in telemedicine consultations. However, there remains no accurate and objective measurement of wound size integrated into these photos. The NDKare mobile phone application has been developed to address this need and our study evaluates its accuracy and practicality for DFU wound size assessment. The NDKare mobile phone application was evaluated for its accuracy in two- (2D) and three-dimensional (3D) wound measurement. One hundred and fifteen diabetic foot wounds were assessed for wound surface area, depth and volume accuracy in comparison to Visitrak and the WoundVue camera. Thirty five wounds had two assessors with different mobiles phones utilizing both applications to assess the reproducibility of the measurements. The 2D surface area measurements by NDKare showed excellent concordance with Visitrak and WoundVue measurements (ICC: 0.991 [95% CI: 0.988, 0.993]) and between different users (ICC: 0.98 [95% CI: 0.96, 0.99)]. The 3D NDKare measurements had good agreement for depth and fair agreement for volume with the WoundVue camera. The NDKare phone application can consistently and accurately obtain 2D measurements of diabetic foot wounds with mobile phone photography. This is a quick and readily accessible tool which can be integrated into comprehensive diabetic wound care.
准确测量糖尿病足溃疡（DFU）伤口大小至关重要，因为伤口愈合速度是伤口完全愈合可能性的重要预后指标。手机摄影常用于监测和辅助远程医疗会诊。然而，这些照片中仍没有对伤口大小进行准确、客观的测量。已开发出NDKare手机应用程序来满足这一需求，我们的研究评估了其在DFU伤口大小评估中的准确性和实用性。对NDKare手机应用程序在二维（2D）和三维（3D）伤口测量方面的准确性进行了评估。与Visitrak和WoundVue相机相比，对115个糖尿病足伤口的伤口表面积、深度和体积准确性进行了评估。35个伤口由两名使用不同手机的评估者使用这两种应用程序来评估测量的可重复性。NDKare进行的2D表面积测量与Visitrak和WoundVue测量结果显示出极好的一致性（组内相关系数：0.991 [95%置信区间：0.988, 0.993]），并且在不同用户之间也具有良好的一致性（组内相关系数：0.98 [95%置信区间：0.96, 0.99]）。NDKare的3D测量结果与WoundVue相机在深度方面具有良好的一致性，在体积方面具有中等一致性。NDKare手机应用程序可以通过手机摄影一致且准确地获取糖尿病足伤口的2D测量结果。这是一个快速且易于使用的工具，可整合到全面的糖尿病伤口护理中。
