Outcome Measures

Primary Outcomes (10)

  • Number of Participants Recruited

    The ability to recruit 10 caregivers who were eligible for the study was used with other variables to assess feasibility

    5 months

  • Number of Caregivers Retained

    Retain 10 caregivers was used with other variables to assess feasibility

    At study completion (2 months [treatment] or 3 months [waitlist control])

  • Number of Participants With Ability to Install the Automated Bidets, Including Any Modifications Needed

    Installation of the automated bidets and a record of any modifications needed was used with other variables to assess feasibility

    30 days post-installation

  • Number of Caregivers' or Care Recipients' Who Can Operate the Bidet

    Demonstrate ability to operate the bidet successfully which was used with other variables to assess feasibility

    30 days post-installation

  • Acceptability

    8-item process evaluation: rated on a scale of 0 (strongly disagree) to 4 (strongly agree) with higher scores indicating greater acceptance of the intervention

    30 days post-installation

  • Preliminary Efficacy: Performance

    In-Home Occupational Performance Evaluation for Providing Assistance impact on caregiver outcomes rated on a scale of 1 to 5 with higher scores indicating better performance was used with other variables to assess feasibility

    2 months (treatment) or 3 months (waitlist control)

  • Preliminary Efficacy: Satisfaction

    In-Home Occupational Performance Evaluation for Providing Assistance: impact on caregiver outcomes rated on a scale of 1 to 5 with higher scores indicating better satisfaction was used with other variables to assess feasibility

    2 months (treatment) or 3 months (waitlist control)

  • Preliminary Efficacy: Self-efficacy

    In-Home Occupational Performance Evaluation for Providing Assistance: impact on caregiver outcomes rated on a scale of 1 to 5 with higher scores indicating better self-efficacy was used with other variables to assess feasibility

    2 months (treatment) or 3 months (waitlist control)

  • Preliminary Efficacy: Physical Environmental Barriers

    In-Home Occupational Performance Evaluation for Providing Assistance: reduction of physical barriers to toileting (rated on a scale from 0 (independent) to 5 (no activity/dependent) was used with other variables to assess feasibility

    2 months (treatment) or 3 months (waitlist control)

  • Adverse Events

    Number of adverse events was used with other variables to assess feasibility

    At study completion (2 months [treatment] or 3 months [waitlist control])

Study Arms (2)

Treatment

EXPERIMENTAL

Participants assigned to this group will receive an automated bidet (TOTO Washlet S300e with remote control) and an occupational therapy intervention over 2-3 in-home visits.

Behavioral: Automated Bidet

Waitlist Control

ACTIVE COMPARATOR

Caregivers will wait for 30 days and then will be offered the intervention.

Other: No Intervention

Interventions

Automated BidetBEHAVIORAL

During the first intervention visit, a licensed contractor will install the bidets in participants' homes. The OT will then educate and train the caregiver and care recipient to successfully use the bidet, and make any modifications to the remote as needed. Throughout the intervention, the OT will use motivational enhancement strategies. The OT will make minor modifications to the remote as needed. A second intervention visit will occur 1-2 weeks post-installation to address any new difficulties. Check-in phone calls will be offered to the caregiver and care recipient if needed.
