Objectives-Evaluate effects of a multi component intervention on fecal (FI) and urinary incontinence (UI) outcomes
Design-Randomized controlled trial
Setting-Six nursing homes
Participants-One hundred and twelve Nursing Home (NH) residentsIntervention-Intervention subjects offered toileting assistance, exercise, and choice of food / fluid snacks every 2 hours for 8 hours per day over 3 months.Measurements-Frequency of UI and FI and rate of appropriate toileting as determined by direct checks from research staff. Anorectal assessments were completed on subset of 29 residents.Results-Intervention significantly increased physical activity, frequency of toileting and food/ fluid intake Urinary incontinence improved (p<.05) as did frequency of bowel movements (p<.01) and percent of bowel movements (p <.01) in toilet. The frequency of fecal incontinence did not Corresponding Author: John F.

Most subjects (89%) who underwent anorectal testing showed a dyssynergic voiding pattern which could explain the lack of efficacy of this intervention program alone on fecal incontinence.
Conclusion-The multi-component intervention significantly changed multiple risk factors associated with fecal incontinence and increased bowel movements without decreasing fecal incontinence. The dyssynergic voiding pattern and rectal hyposensitivity suggest that future interventions may have to be supplemented with bulking agents (fiber) and/or biofeedback therapy to improve bowel function.
