[Incontinence-associated dermatitis: a position paper]

Incontinence-associated dermatitis (IAD) describes damage to the skin caused by repeated and prolonged contact with urine and/or feces. Patients of all ages can be affected; the diagnosis is preferably used in adults and adolescents. The predilection sites are perineal, perianal, the inner thighs and the convex areas of the buttocks. Increased moisture on the skin surface, increased pH, occlusion, feces digestive enzymes and repeated skin cleansing procedures are pathophysiologically relevant factors. Typical clinical signs of IAD are erythema, erosions, excoriations and pain. Diagnosis is often difficult because there are many relevant differential diagnoses, some of which may occur together with an IAD. In particular, pressure ulcer, contact dermatitis and intertrigo need to be differentiated and treated. Effective strategies of prevention and therapy of IAD are continence management, the use of efficient, absorbent products as well as consistent skin protection and care. IAD is a skin disease that is often not or incorrectly diagnosed. It should be treated as early as possible, together with the causative factors such a fecal and/or urinary incontinence, as otherwise it can lead to an unnecessarily long duration and severity of the symptoms.
