Disease State: Incontinence-associated dermatitis (IAD)


Incontinence-associated dermatitis (IAD) is an irritant contact dermatitis from prolonged contact with urine or faeces as a result of incontinence. It occurs in all age groups but the prevalence is highest in aged care settings and geriatric populations. The lack of comparable trial outcomes is a major challenge in the field of evidence-based IAD prevention and treatment. Core outcome sets may be helpful to improve the value of clinical incontinence-associated dermatitis research.

Project Goal

After reviews and international Delphi studies five core outcome domains were proposed: erythema, erosion, maceration, incontinence-associated dermatitis-related pain and patient satisfaction. The goal is now to identify outcome measurement instruments per domain.
