Moisture Associated Skin Damage (MASD) - ANS inflammation and erosion of the skin caused
by prolonged exposure to various sources of moisture
Intertriginous Dermatitis (ITD) - ANS a type of MASD, inflammation and skin erosion involving
body folds and friction of skin to skin

associated with effluent exposure such as urine or stool
Periwound MASD (PWMASD) - ANS inflammation and erosion of the skin around a chronic
wound associated with sustained contact of wound exudate
Incontinence Associated Dermatitis (IAD) - ANS a type of MASD, inflammation caused by the
prolonged exposure to urine, feces, or dual incontinence
Medical Adhesive-Related Skin Injury (MARSI) - ANS erythema (or other manifestation) of
cutaneous abnormality that persists 30 minutes of more after removal of adhesive dressing or
tape, types: maceration, mechanical trauma (i.e. skin tear), tension blister, folliculitis
