Abstract

Background. Objective assessment of wound dimensions is essential for tracking progression and determining treatment effectiveness. A reliability study was designed to establish intrarater and interrater reliability of a novel mobile 3-dimensional wound measurement (3DWM) device. Methods. Forty-five wounds were assessed by 2 raters using a 3DWM device to obtain length, width, area, depth, and volume measurements. Wounds were also measured manually, using a disposable ruler and digital planimetry. The intraclass correlation coefficient (ICC) was used to establish intrarater and interrater reliability. Results. High levels of intrarater and interrater agreement were observed for area, length, and width; ICC = 0.998, 0.977, 0.955 and 0.999, 0.997, 0.995, respectively. Moderate levels of intrarater (ICC = 0.888) and interrater (ICC = 0.696) agreement were observed for volume. Lastly, depth yielded an intrarater ICC of 0.360 and an interrater ICC of 0.649. Measures from the 3DWM device were highly correlated with those obtained from scaled photography for length, width, and area (ρ = 0.997, 0.988, 0.997, P < 0.001). The 3DWM device yielded correlations of ρ = 0.990, 0.987, 0.996 with P < 0.001 for length, width, and area when compared to manual measurements. Conclusion. The 3DWM device was found to be highly reliable for measuring wound areas for a range of wound sizes and types as compared to manual measurement and digital planimetry. The depth and therefore volume measurement using the 3DWM device was found to have a lower ICC, but volume ICC alone was moderate. Overall, this device offers a mobile option for objective wound measurement in the clinical setting.
