Ulcer area is a critical parameter in diabetic foot ulcer assessment but existing methods have deficiencies for routine measurement.
We hypothesized that the Image J-based Computer Analysis method has a high level of agreement with the commonly used Maximum Length and Width and the Transparent Dressing-based Square Grid methods and aimed to test the consistency and verify the feasibility of the Image J-based Computer Analysis method in the routine assessment of ulcers.
Outpatient attendees with diabetic foot ulcers at the Department of Endocrinology of Sun Yat-sen Memorial Hospital were enrolled between October 2020 and October 2021. The three methods sequentially assessed the area of 65 included ulcers. Results were analysed using one-way analysis of variance and Bland-Altman plots to perform consistency analysis.
The mean ± standard deviation ulcer area measured using the three methods were 14.79 ± 5.39, 14.35 ± 5.26, and 14.30 ± 5.26 cm , respectively. The measurement differences among the three groups or between any two were not statistically significant. Bland-Altman plots showed good consistency between the Image J-based Computer Analysis and the other two methods.
The Image J-based Computer Analysis method can be interchanged with the other methods to assess ulcer areas. It is freely accessible, accurate and home-operable, thus worth consideration by nurses for routine ulcer area assessment.
溃疡面积是糖尿病足溃疡评估中的一个关键参数，但现有方法在常规测量方面存在不足。
我们假设基于Image J的计算机分析方法与常用的最大长度和宽度法以及基于透明敷料的方格法具有高度一致性，并旨在测试基于Image J的计算机分析方法在溃疡常规评估中的一致性并验证其可行性。
2020年10月至2021年10月，招募了中山大学孙逸仙纪念医院内分泌科门诊的糖尿病足溃疡患者。三种方法依次评估了65例纳入研究的溃疡面积。使用单因素方差分析和Bland-Altman图进行结果分析以进行一致性分析。
三种方法测量的溃疡面积的平均值±标准差分别为14.79±5.39、14.35±5.26和14.30±5.26cm²。三组之间或任意两组之间的测量差异均无统计学意义。Bland-Altman图显示基于Image J的计算机分析方法与其他两种方法之间具有良好的一致性。
基于Image J的计算机分析方法可与其他方法互换使用以评估溃疡面积。它免费可用、准确且可在家操作，因此值得护士在溃疡面积常规评估中考虑。
