Facial redness is a common concern in dermatology, affecting patients with conditions such as rosacea, post-inflammatory erythema, and other vascular irregularities. Despite its prevalence, existing tools for quantifying facial redness are limited in their clinical utility and ease of use.
To develop a high-performing redness scale.
This study introduces the Kesty Redness Scale (KRS), outlines its development and validation process, and discusses its potential clinical applications.
The investigators rated the scale as useful and easy to use, and the majority stated they would use it in clinical practice to document patient characteristics. The results of the evaluation utilizing Gwet's AC2, Kendall's W, Spearman's ρ, Weighted Cohen's kappa, and Bland-Altman analysis -showcasing strong ordinal agreement, robust rank concordance, and negligible bias-demonstrate that this new rating system is both reliable and valid for measuring skin hyperpigmentation on a 0-3 scale.
The KRS is a reliable, easy-to-use tool that enhances the assessment of facial redness in dermatology. Its validation through expert evaluation and statistical analysis underscores its potential to improve clinical practice and research.
面部发红是皮肤科常见问题，影响酒渣鼻、炎症后红斑及其他血管异常疾病的患者。尽管其很常见，但现有的面部发红量化工具在临床实用性和易用性方面存在局限。
开发一种高性能的发红量表。
本研究介绍了凯斯蒂发红量表（KRS），概述了其开发和验证过程，并讨论了其潜在的临床应用。
研究者们认为该量表有用且易于使用，大多数人表示会在临床实践中使用它来记录患者特征。利用Gwet's AC2、肯德尔W系数、斯皮尔曼ρ系数、加权科恩kappa系数和布兰德-奥特曼分析进行评估的结果——显示出强烈的序数一致性、稳健的秩一致性和可忽略的偏差——表明这个新的评分系统在0至3级量表上测量皮肤色素沉着既可靠又有效。
KRS是一种可靠、易于使用的工具，可增强皮肤科对面部发红的评估。通过专家评估和统计分析对其进行验证，凸显了其改善临床实践和研究的潜力。
