The objective of this study was to compare live and photographic assessments of clinical signs of diabetic foot disease using a new photographic foot imaging device. High quality colour photographs of the plantar foot surface were collected in 20 diabetic feet using a prototype device and in 19 diabetic feet using a definitive version of the device with optimized illumination settings. All photographs were assessed independently by four observers for presence of ulceration, abundant callus, or absence of signs and compared with live and repeated photographic assessments of the feet by the same observers. Agreement between assessments was moderate to good for all outcomes using the prototype device (56-92%) and improved using the definitive version of the device (74-100%). The data seem to suggest that important signs of diabetic foot disease can be diagnosed from high quality photographs using the photographic foot imaging device. Intended for use as telemedical monitoring device in the patients' home, frequent remote assessments may potentially contribute to the early recognition and treatment of foot disease, which may prevent further complications.
本研究的目的是使用一种新型足部摄影成像设备，比较糖尿病足病临床体征的现场评估和摄影评估。使用原型设备为20只糖尿病足采集了足底表面的高质量彩色照片，使用具有优化照明设置的设备最终版本为19只糖尿病足采集了照片。四名观察者独立评估所有照片中是否存在溃疡、大量胼胝或无体征情况，并将其与同一观察者对足部的现场评估和重复摄影评估进行比较。使用原型设备时，所有结果的评估之间的一致性为中等至良好（56%-92%），使用设备最终版本时一致性有所提高（74%-100%）。数据似乎表明，使用足部摄影成像设备从高质量照片中可以诊断出糖尿病足病的重要体征。该设备旨在用作患者家中的远程医疗监测设备，频繁的远程评估可能有助于早期识别和治疗足部疾病，从而预防进一步的并发症。
