OBJECTIVES: We aimed to determine (1) the prevalence of constipation among inpatients, (2) the prevalence and symptoms of difficult defecation among constipated inpatients, and (3) the factors associated with constipation. METHODS: We performed a retrospective cohort study over a single day at one university hospital. We analyzed the nursing records for inpatients who had been hospitalized for at least 3 days. The survey items included the symptoms associated with defecation difficulty and nutritional intake. The symptoms of difficult defecation were defined as (1) fewer than three spontaneous bowel movements per week; (2) lumpy or hard stools (Bristol stool form scale types 1-2); (3) straining during defecation; and (4) the sensation of incomplete evacuation during defecation, based on the Roma-IV diagnostic criteria. Constipation was defined as the presence of two or more symptoms of defecation difficulty. Univariate and multivariate analyses were performed to determine the constipation status of the patients. RESULTS: The prevalence of constipation in the university hospital was 12.2%, and the department with the highest prevalence of difficulty with defecation was the Psychiatry Department (64.1%). Of the patients with constipation, 36.8% exhibited symptoms of defecation difficulty other than low frequency of defecation. The factor that was significantly associated with constipation after admission was pre-admission constipation (odds ratio=8.92, p<0.01). CONCLUSIONS: Subjective assessment has limitations for the accurate determination of constipation status. In addition, patients with a history of constipation before admission require early interventions to aid defecation following their admission.

We aimed to investigate the association between the presence of cutaneous urease-producing bacteria and the development of incontinence-associated dermatitis (IAD) using an original urea agar medium as a step toward developing advanced preventive measures. In previous clinical assessments, we developed an original urea agar medium to detect urease-producing bacteria via the medium's colour changes. In a cross-sectional study, specimens were collected via the swabbing technique at genital skin sites in 52 stroke patients hospitalised in a university hospital. The primary objective was to compare the presence of urease-producing bacteria between the IAD and no-IAD groups. Determining the bacterial count was the secondary objective. The prevalence of IAD was 48%. A significantly higher detection rate of urease-producing bacteria was observed in the IAD group than in the no-IAD group (P = .002) despite the total number of bacteria being equivalent between them. In conclusion, we discovered that there was a significant association between the presence of urease-producing bacteria and IAD development in hospitalised stroke patients.
