Randomized Trial of Culture Directed Versus Empiric Antibiotics for Urinary Tract Infections in Older Women

Phase 4
Completed
Conditions
UTI
Interventions
Drug: Antibiotics
Registration Number
NCT05726318
Lead Sponsor
Megan Bradley
Brief Summary

To evaluate the feasibility of recruiting eligible subjects into a randomized trial of a culture-directed versus empiric antibiotic strategy for patient-reported UTI symptoms in older women and the adherence to study procedures.

Detailed Description

To evaluate A) the feasibility of recruiting eligible subjects into a randomized trial of a culture-directed versus empiric antibiotic strategy for patient-reported UTI symptoms in older women and B) the adherence to study procedures. We will recruit and enroll women with a history of rUTI from the Women's Center for Bladder and Pelvic Health and the University of Pittsburgh's Clinical and Translational Science Institute (CTSI) Pitt+Me® Research Registry. Once enrolled and randomized, women will be followed for a total of 28 days to document both clinical resolution at day 7 from symptom onset and adverse events. H1) Enrolling a total of 70 subjects in \<1 year (at least 10% of eligible patients) will demonstrate feasibility of recruitment and H2) Documenting at least 70% patient compliance with study procedures will confirm patient adherence to study protocol. Exploratory Aim: To explore the safety of a culture-directed UTI treatment strategy and preliminary secondary outcomes of assigned treatments. H1) There will be an overall low number of adverse events and H2) Preliminary outcome data will help power future trial.

GroupInterventionDescription
Culture-directed antibioticAntibioticsParticipants will be directed to refrain from taking antibiotics until results of urine culture are reported, which is expected within 48-72h.
Empiric antibioticAntibioticsAntibiotic Protocol. For participants in the empiric Rx arm, we will choose an antibiotic with consideration of patient reported allergies, current medications and current IDSA guidelines. If there is a contraindication to the first antibiotic on the list they will progress to the next option until a suitable selection is achieved.
