The development of the objective risk assessment indicator for incontinence-associated dermatitis

尿失禁相关性皮炎（IAD）是一种常见的皮肤疾病，在患者的粪便和/或尿失禁。然而，还没有确定哪些特定的皮肤状况有IAD的高风险。这项研究的重点是皮肤浸渍作为IAD的危险因素。结果表明：浸泡组角质层和真皮水化水平、经皮失水和皮肤pH值显著高于未浸泡组。本研究表明，皮肤浸渍不仅影响表皮，而且影响真皮层，导致皮肤屏障功能低下。此外，对浸渍分类的ROC分析显示，在其他视觉变量中，红斑指数（Erythema Index， EI）是最好的浸渍分类器。EI可以作为医疗保健专业人员正确诊断浸渍的有用工具。

Incontinence-associated dermatitis(IAD) is a common skin disorder in patients with faecal and/or urinary incontinence. However, it has not been determined which specific skin conditions have a high risk of IAD. This study focused on skin maceration as a risk factor for IAD. The results showed that the hydration level in the stratum corneum and dermis, transepidermal water loss and skin pH levels were significantly higher in the maceration group than in the non-maceration group. This study demonstrated that skin maceration affects not only the epidermis but also the dermis and leads to poor skin barrier function. Additionally, ROC analysis for classification of maceration showed that Erythema Index(EI) is the best classifier of maceration among other visual variables. EI could be a useful tool for healthcare professionals to make a correct diagnosis of maceration.
