To explore the feasibility of Jefcare Sterile Medical Sheets in preventing incontinence-associated dermatitis and maintaining a stable local skin microclimate in adult patients in the intensive care unit.

Jefcare Sterile Medical Sheet is an incontinence care product designed by researchers following the Expert consensus on the clinical application of disposable absorbent care products for adults with incontinence. The product has good laboratory test indicators and has the potential to prevent incontinence-associated dermatitis and maintain the stability of the local skin microclimate.
