BACKGROUND: Incontinence-associated dermatitis (IAD) is a prevalent and distressing form of irritant contact dermatitis caused by prolonged exposure to urine and/or faeces. Not all incontinent individuals develop IAD, suggesting that additional prognostic factors contribute to its onset. The quality of empirical evidence supporting risk factors for IAD development is moderate to very low. Therefore, it is necessary to systematically compile and analyse expert knowledge on this topic.

AIM: This study aimed to identify and prioritise key prognostic factors for IAD development through an international expert consultation.

MATERIALS AND METHODS: A cross-sectional expert survey was conducted among international experts using an electronic survey platform. Participants rated the importance of 26 pre-identified prognostic factors, ranked relevant factors and suggested additional factors. Data were analysed to determine expert consensus and factor rankings.

RESULTS: A total of 45 experts participated, with a response rate of 39 %. The highest-ranked prognostic factors included double incontinence, faecal incontinence, loose stools, stool frequency, urinary incontinence, and impaired mobility. Other important factors were advanced age, friction and shear forces, cognitive impairment, and poor nutrition. In addition, experts highlighted systemic factors such as caregiver knowledge gaps and staff shortages as potential contributors to IAD risk.

CONCLUSION: Study results support established risk factors for IAD development such as stool frequency and limited mobility. Experts also identified factors, such as higher age and the presence of loose or liquid stool, that are considered relevant by experts but are not yet fully supported by empirical evidence. Findings will inform a future large-scale cohort study.
