To explore the current status of knowledge, attitudes, and practices (KAP) regarding incontinence-associated dermatitis (IAD) among clinical nurses in China and identify factors influencing these three aspects, this study adopted a cross-sectional design and was conducted in a tertiary hospital in Fujian Province, China, with 1,153 nurses completing the questionnaire.
