记录慢性下肢溃疡愈合过程的伤口测量在这些患者的管理中具有重要作用。智能手机中的数码相机随处可得，使用方便，拍摄伤口照片正在成为专业部门的常规。使用适当的软件分析数字图像为临床医生提供了一种快速，干净，易于使用的工具来测量伤口面积。一组25个数字照片的平原足和腿部溃疡是这项研究的基础。用iPhone 6S（Apple Inc，库比蒂诺，CA）将尺子放置在伤口旁边与健康皮肤平行地拍摄照片，iPhone 6S具有使用闪光灯的1200万像素的相机。用ImageJ 1.45s免费软件（National Institutes of Health，Rockville，MD; http：//imagej.net/ImageJ）可视化数字照片。伤口面积测量由4名评估者进行：科室负责人、伤口护理护士、医生和医学生。我们使用组间相关系数评估了评定者内和评定者间的可靠性。为了确定观察者内部的可靠性，2名评定者在第一次阅读后1周重复测量该集合。评价者间模型显示的组间相关系数为0.99，95%置信区间为0.999至1.000，显示出良好的可靠性。两个考官的intrarater模型显示出良好的可靠性。总之，使用ImageJ分析腿部溃疡的数字图像估计伤口面积具有良好的可靠性。该方法提供了一种免费、快速和准确的方法来测量伤口，并可在日常临床实践中常规用于记录伤口愈合。
Wound measurement to document the healing course of chronic leg ulcers has an important role in the management of these patients. Digital cameras in smartphones are readily available and easy to use, and taking pictures of wounds is becoming a routine in specialized departments. Analyzing digital pictures with appropriate software provides clinicians a quick, clean, and easy-to-use tool for measuring wound area. A set of 25 digital pictures of plain foot and leg ulcers was the basis of this study. Photographs were taken placing a ruler next to the wound in parallel with the healthy skin with the iPhone 6S (Apple Inc, Cupertino, CA), which has a camera of 12 megapixels using the flash. The digital photographs were visualized with ImageJ 1.45s freeware (National Institutes of Health, Rockville, MD; http://imagej.net/ImageJ). Wound area measurement was carried out by 4 raters: head of the department, wound care nurse, physician, and medical student. We assessed intra-and interrater reliability using the interclass correlation coefficient. To determine intraobserver reliability, 2 of the raters repeated the measurement of the set 1 week after the first reading. The interrater model displayed an interclass correlation coefficient of 0.99 with 95% confidence interval of 0.999 to 1.000, showing excellent reliability. The intrarater model of both examiners showed excellent reliability. In conclusion, analyzing digital images of leg ulcers with ImageJ estimates wound area with excellent reliability. This method provides a free, rapid, and accurate way to measure wounds and could routinely be used to document wound healing in daily clinical practice.
