BACKGROUND/PURPOSE: The color of a wound bed reflects its degree of 'cleanness' and serves as an indicator in evaluating the progression of wounds toward healing. We were aiming to develop a standard tool, for use in clinical research studies, which would analyze and provide objective data as to the color distribution of wound surfaces. To this end, we designed the 'Scaled Healing Assessment Index' algorithmic tool to provide a scoring system to determine the average color of wound surfaces.
The scale is graded from 1 to 10, with 1 representing the most unclean yellow wound, and 10 representing the optimal red wound. In order to test the accuracy of the software, 102 chronic wounds in 88 patients were examined. Each wound was assessed using a grading from 1 to 10, according to its color, using three separate methods: (1) by three dermatologists [average clinical score (ACS)] in the outpatient clinic; (2) by three other dermatologists with the same wounds presented on a computer screen [average photo score (APS)]; and (3) by the Scaled Healing Assessment Index [software score (SS)]. The results of the three methods were examined statistically using Pearson's correlation.
We found a high correlation between the ACSs and the SSs (0.86), between the APSs and the SSs (0.863), as well as the ACSs with the APSs (0.95).
The Scaled Healing Assessment Index algorithm provides objective and reliable data, and can be used in research studies aimed at examining the beneficial effect of products intended for wound healing.
背景/目的：伤口床的颜色反映其“清洁”程度，是评估伤口愈合进程的一项指标。我们旨在开发一种用于临床研究的标准工具，该工具能够分析并提供有关伤口表面颜色分布的客观数据。为此，我们设计了“标准化愈合评估指数”算法工具，以提供一个评分系统来确定伤口表面的平均颜色。
该量表从1到10进行分级，1代表最不干净的黄色伤口，10代表最佳的红色伤口。为了测试该软件的准确性，对88例患者的102处慢性伤口进行了检查。根据伤口颜色，使用三种不同方法对每个伤口进行1至10级评分：（1）由门诊的三位皮肤科医生进行评分[平均临床评分（ACS）]；（2）由另外三位皮肤科医生在电脑屏幕上查看相同伤口进行评分[平均照片评分（APS）]；（3）通过标准化愈合评估指数进行评分[软件评分（SS）]。使用Pearson相关性对三种方法的结果进行统计学检验。
我们发现ACS与SS之间的相关性较高（0.86），APS与SS之间的相关性较高（0.863），ACS与APS之间的相关性也较高（0.95）。
标准化愈合评估指数算法可提供客观可靠的数据，可用于旨在研究伤口愈合产品有益效果的研究。
