Quality of Life in Adults Impaired Functioning - A Randomized Controlled Trial of Bidet vs Usual Toileting

Our expectations (hypotheses) are:

Primary outcome

1. Regular bidet use will improve quality of life around elimination in adults with impaired functional status. Functional status will be measured by activities of daily living (ADL).

2. Regular bidet use by adults with impaired functional status will improve the quality of life around toileting for their caregivers.


3. Regular bidet use will reduce the incidence, frequency and severity of constipation (as measured by self-report) in adults with impaired functional status.

4. Regular bidet use will reduce the incidence of urinary tract infection (UTI) in adult women with impaired functional status.

Stanford is currently not accepting patients for this trial.
