Monitoring wound progression to healing in diabetic foot ulcers using three-dimensional wound imaging.
Malone M et al
J Diabetes Complications. 2019 Nov 4

AIM:
3D wound imaging has provided clinicians with even greater wound measurement options. No data is available to guide clinicians as to which 3D measurements may yield the most reflective marker of wound progression to healing.

METHOD:
A prospective pilot study was undertaken to assess the accuracy of five 3D wound measurements that best reflect metrics of interest to clinicians. Twenty-one diabetic foot ulcers were enrolled from initial ulcer presentation, through to healing. The relationship between mean wound healing measurement variables was examined using linear regression and Pearsons correlation coefficient, in addition to assessing clinician inter-rater reliability of measurements using Intra-class correlation coefficients (ICC).

RESULTS:
Statistical analysis demonstrated a linear healing slope for each wound measurement as having a value greater than R 0.70 and a statistical significance of p = 0.0001. This suggests that all five wound measurements are useful prognostic markers of wound progression to healing. Low variability of measurements between users indicates good inter-observer reliability.

CONCLUSION:
3D wound measurements demonstrate a linear correlation between the measurement and time to healing. This suggests they could be effective prognostic markers of a wounds progression to healing and closure. It may also provide important early identification of wounds not responding to standard care. Larger studies are required to validate our results.

There is a lifetime risk of 15% to 25% of development of diabetic foot ulcers (DFUs) in patients with diabetes mellitus. DFUs need to be followed up on and assessed for development of complications and/or resolution, which was traditionally performed using manual measurement. Our study aims to compare the intra- and inter-rater reliability of an artificial intelligence-enabled wound imaging mobile application (CARES4WOUNDS [C4W] system, Tetsuyu, Singapore) with traditional measurement. This is a prospective cross-sectional study on 28 patients with DFUs from June 2020 to January 2021. The main wound parameters assessed were length and width. For traditional manual measurement, area was calculated by overlaying traced wound on graphical paper. Intra- and inter-rater reliability was analysed using intra-class correlation statistics. A value of <0.5, 0.5–0.75, 0.75–0.9, and >0.9 indicates poor, moderate, good, and excellent reliability, respectively. Seventy-five wound episodes from 28 patients were collected and a total of 547 wound images were analysed in this study. The median wound area during the first clinic consultation and all wound episodes was 3.75 cm2 (interquartile range [IQR] 1.40–16.50) and 3.10 cm2 (IQR 0.60–14.84), respectively. There is excellent intra-rater reliability of C4W on three different image captures of the same wound (intra-rater reliability ranging 0.933–0.994). There is also excellent inter-rater reliability between three C4W devices for length (0.947), width (0.923), and area (0.965). Good inter-rater reliability for length, width, and area (range 0.825–0.934) was obtained between wound nurse measurement and each of the C4W devices. In conclusion, we obtained good inter-rater and intra-rater reliability of C4W measurements against traditional wound measurement. The C4W is a useful adjunct in monitoring DFU wound progress.
