Abstract

Aim: To compare the isolated and identified bacterial species colonizing on the genital skin between patients with and without incontinence-associated dermatitis. Methods: This cross-sectional study included 102 patients with stroke admitted to an acute hospital in Japan. Swabs were collected, and bacterial species found in swabs were isolated and identified using a selective agar medium and simple identification kits. In addition to demographic information, severity of incontinence-associated dermatitis and the total bacterial counts were measured. Results: Incontinence-associated dermatitis was present in 53.9% of the participants. Staphylococcus aureus was found in 50% of the participants with incontinence-associated dermatitis and only 17.9% of those without incontinence-associated dermatitis (P = 0.0029). Bacterial species distribution by erythema and skin erosion, which denote severity of incontinence-associated dermatitis, was different, but not significant; additionally, the total number of bacterial colonies was equivalent. Conclusions: Bacterial species distribution differed between patients with and without incontinence-associated dermatitis, whereas the total number of bacterial colonies was equivalent. A high detection rate of S. aureus on genital skin sites potentially affects the presence of incontinence-associated dermatitis and its severity. Geriatr Gerontol Int 2023; 23: 537–542.
