Abstract

Background: Telangiectasia is a prominent feature of rosacea leading to a high demand for effective treatment. To ensure consistent clinical and scientific evaluations and assess treatment response accurately, standardized assessment tools are necessary for grading the severity of telangiectasia. However, no validated grading scales for this condition are currently available.

Aim: To develop and validate a photonumeric scale for assessing the severity of telangiectasia in rosacea patients.

Methods: The five-point photonumeric Telangiectasia in Rosacea Severity Assessment (TRoSA) scale was developed for the severity of telangiectasia in rosacea. Sixteen experts participated in the validation process, evaluating 50 images of rosacea patients in two rounds. Interrater and intrarater reliability were analyzed using the intraclass correlation coefficient (ICC) and weighted kappa, respectively.

Results: Interrater reliability was found to be "almost perfect" in both validation rounds (Round 1: ICC 0.847; Round 2: ICC 0.828). The mean weighted kappa indicated "substantial" intrarater reliability between the two rounds with a weighted kappa of 0.719. A bubble plot of the two rounds illustrated a diagonal order, confirming the consistency of the intrarater agreement.

Conclusions: The TRoSA scale demonstrated high interrater and intrarater reliability indicating that it is a consistent and reproducible tool for grading the severity of telangiectasia in rosacea. This scale can standardize clinical assessments, assisting in diagnosis, treatment planning, and evaluation of therapeutic efficacy.

用于评估红斑痤疮毛细血管扩张的光敏数字量表的验证。

背景：毛细血管扩张是红斑痤疮的一个显著特征，因此对有效治疗的需求很高。为了确保临床和科学评价的一致性，并准确评估治疗反应，有必要使用标准化的评估工具对毛细血管扩张的严重程度进行分级。目的：开发并验证用于评估红斑痤疮患者毛细血管扩张严重程度的光敏数字量表：方法：针对红斑痤疮毛细血管扩张的严重程度，开发了五点光敏数字式红斑痤疮毛细血管扩张严重程度评估量表（TRoSA）。16 位专家参与了验证过程，分两轮对 50 张酒糟鼻患者的图像进行了评估。分别使用类内相关系数（ICC）和加权卡帕分析了交互信度和交互信度：结果：在两轮验证中，评分者之间的可靠性 "几乎完美"（第一轮：ICC 0.847；第二轮：ICC 0.828）。加权卡帕平均值为 0.719，表明两轮验证的内部评分可靠性 "相当高"。两轮问卷的气泡图显示了对角线顺序，证实了研究者内部一致性：结论：TRoSA量表显示出较高的研究者间和研究者内可靠性，表明它是对酒糟鼻毛细血管扩张严重程度进行分级的一致且可重复的工具。该量表可使临床评估标准化，有助于诊断、治疗计划和疗效评估。
