摘要

目的我们在早期开发了一款糖尿病足溃疡智能测量APP，命名为糖尿病足智能APP。方法我们选取了 150 张糖尿病足溃疡图像，使用智能 APP 软件包、尺子法和金标准 Image J 软件三种评估工具测量溃疡面积，并比较了三种工具的测量结果和测量时间。结果 Image J 软件显示的中位溃疡面积为 4.02 cm2，平均测量时间为 66.37 ± 7.95 s；直尺法显示的中位溃疡面积为 5.14 cm2，平均测量时间为 171.尺法与黄金标准 Image J 软件之间存在显著差异（Z = -4.123，p < 0.05），但 APP 软件与 Image J 软件之间没有显著差异（Z = 1.103，p > 0.05）。结论糖尿病足智能 APP 是一种快速可靠的测量工具，测量精度高，可方便地用于临床实践中对 DFU 溃疡面积的测量：中国临床试验注册号：ChiCTR2100047210。

Application of a Diabetic Foot Smart APP in the measurement of diabetic foot ulcers

Aims

In the early stage, we developed an intelligent measurement APP for diabetic foot ulcers, named Diabetic Foot Smart APP. This study aimed to validate the APP in the measurement of ulcer area for diabetic foot ulcer (DFU).

Methods

We selected 150 DFU images to measure the ulcer areas using three assessment tools: the Smart APP software package, the ruler method, and the gold standard Image J software, and compared the measurement results and measurement time of the three tools. The intra-rater and inter-rater reliability were described by Pearson correlation coefficient, intra-group correlation coefficient, and coefficient of variation.

Results

The Image J software showed a median ulcer area of 4.02 cm², with a mean measurement time of 66.37 ± 7.95 s. The ruler method showed a median ulcer area of 5.14 cm², with a mean measurement time of 171.47 ± 46.43 s. The APP software showed a median ulcer area of 3.70 cm², with a mean measurement time of 38.25 ± 6.81 s. There were significant differences between the ruler method and the golden standard Image J software (Z = −4.123, p < 0.05), but no significant difference between the APP software and the Image J software (Z = 1.103, p > 0.05). The APP software also showed good inter-rater reliability and intra-rater reliability, with both reaching 0.99.

Conclusion

The Diabetic Foot Smart APP is a fast and reliable measurement tool with high measurement accuracy that can be easily used in clinical practice for the measurement of ulcer areas of DFU.
