Wound management is a challenge in terms of the way, duration and cost of treatment both for the patient and health providers. The healing of skin wounds is a highly multi-step coordinated process. Objective monitoring of treatment at every stage is necessary to assess the applied therapy.
To show the possibility of using the AutoCad software (ACS) as a tool with a slight measurement error for accurate measurement of the venous leg ulcers on the lower limbs.
To determine the error of the measurement method Circle Templates For Drafting for four different sizes were used as ulcer models. Seventy-six wounds of various sizes from patients with venous leg ulcers (VLUs) were photographed and outlined with a marker on a transparent foil. The wounds were measured both using ACS and digital planimetry with C-Geo software (CGS). Data were analysed using Wilcoxon test, intraclass correlation coefficient (ICC) and Bland-Altman analysis.
The mean relative error of the surface wound model area measured by the ACS was 0.30 ±0.31% (range: 0.004-1.25) and a median of 0.18%. Areas and perimeters measured with ACS were higher than areas and perimeters measured with CGS, and the difference was statistically significant.
The analysis of the wound images obtained in the ACS showed a very high potential of the software in terms of the accuracy of the analysed areas, which significantly increases the possibility of the analysis and reduces the measurement error in relation to planimetry using a digital digitizer.
伤口管理对于患者和医疗服务提供者而言，在治疗方式、持续时间和成本方面都是一项挑战。皮肤伤口的愈合是一个高度多步骤协调的过程。在每个阶段对治疗进行客观监测对于评估所应用的疗法是必要的。
展示使用AutoCad软件（ACS）作为一种测量误差较小的工具来精确测量下肢静脉性腿部溃疡的可能性。
为确定测量方法的误差，使用四种不同尺寸的绘图圆模板作为溃疡模型。对76例患有静脉性腿部溃疡（VLU）患者的各种大小的伤口进行拍照，并在透明箔纸上用记号笔勾勒出轮廓。使用ACS和C-Geo软件（CGS）的数字平面测量法对伤口进行测量。使用Wilcoxon检验、组内相关系数（ICC）和Bland-Altman分析对数据进行分析。
ACS测量的伤口模型表面面积的平均相对误差为0.30±0.31%（范围：0.004 - 1.25），中位数为0.18%。用ACS测量的面积和周长高于用CGS测量的面积和周长，且差异具有统计学意义。
对在ACS中获得的伤口图像进行分析表明，该软件在分析区域的准确性方面具有很高的潜力，这显著增加了分析的可能性，并相对于使用数字数字化仪的平面测量法减少了测量误差。
