Advances in digital imaging and archiving have made the measurement and documentation of wound areas possible over time. To assess the reproducibility and precision of digital image measurements, we used WoundMatrix Web (http://www.woundmatrix.com/) and recruited a group of caregivers from the Johns Hopkins Wound Center to measure the size of wounds on digital images by measuring length and width and tracing the circumference of the same wounds. One set of images was provided by WoundMatrix (WoundMatrix Inc, Chadds Ford, PA) and a second set used our own photographs taken at the Johns Hopkins Wound Center. Our results demonstrate that digital analysis with WoundMatrix Web is reproducible and precise with acceptable variation among readers. This supports the use of digital images of wounds to follow clinical progress as well as analyze the effects of new clinical interventions in clinical trials.
数字成像和存档技术的进步使得随时间推移对伤口面积进行测量和记录成为可能。为了评估数字图像测量的可重复性和精确性，我们使用了WoundMatrix Web（http://www.woundmatrix.com/），并从约翰霍普金斯伤口中心招募了一组护理人员，通过测量长度和宽度以及描绘相同伤口的周长来测量数字图像上伤口的大小。一组图像由WoundMatrix（WoundMatrix公司，宾夕法尼亚州查兹福特）提供，另一组使用我们在约翰霍普金斯伤口中心拍摄的照片。我们的结果表明，使用WoundMatrix Web进行数字分析具有可重复性和精确性，读者之间的差异可接受。这支持使用伤口的数字图像来跟踪临床进展以及分析临床试验中新临床干预措施的效果。
