Outcome Measures

Primary Outcomes (1)

  • Rate of Urinary Tract Infection (UTI)

    The proportion of participants in each arm who experience a urinary tract infection (UTI) within 90 days will be compared

    90 days following treatment initiation

Secondary Outcomes (2)

  • Vulvovaginal Symptom Questionnaire (VSQ)

    VSQ administered prior to randomization and at 6 weeks, 12 weeks, and 24 weeks post-randomization

  • Urinary Distress Inventory (UDI-6)

    UDI-6 administered prior to randomization and at 6 weeks, 12 weeks, and 24 weeks post-randomization

Other Outcomes (1)

  • Participant Satisfaction with Virtual Recruitment

    Upon completion of the intervention period, 90 days after randomization

Study Arms (2)

ACTIVE COMPARATOR

Sterile water perineal lavage following defecation

Drug: Sterile Water

Interventions

Masking Details
Participants will be blinded to their assigned treatment. All participants will receive a box containing their randomized intervention and identical use instructions. Opaque bottles will contain either a sterile water solution or 2% chlorhexidine. Spray bottles will be identical in external appearance.

Model Details: Individuals meeting inclusion criteria will be randomized to the treatment (2% chlorhexidine perineal lavage following defecation) or control (sterile water perineal lavage following defecation) and rates of urinary tract infection will be compared. Balanced randomization will be performed via computer-generated assignments in REDCap with random permuted blocks varying in size between 8 and 10.
