  Purpose

Urinary tract infections (UTIs) affect over 7 million men and women per year and cost the health care industry over 1 billion dollars annually. The incidence of UTI increases markedly in elderly institutionalized persons and leads to excessive antimicrobial usage, emergency room visits, hospitalization, sepsis, and death. The use of antimicrobials to prevent UTI in elderly nursing home patients is not recommended and is fraught with problems such as adverse reactions, drug interactions, and the development of drug-resistant organisms. There is no accepted method of preventing UTI in residents of nursing homes, a vulnerable and understudied population with significant morbidity from UTI.

The overall goal of this proposal is to conduct a prospective cohort pilot study that evaluates the feasibility of using cranberry to prevent UTI in nursing home residents. Each of the aims is critical for the optimal design of a larger placebo-controlled, definitive trial of cranberry for prevention of UTI in nursing home residents and will provide the essential preliminary data for future larger studies.

Primary Outcome Measures:
  • Number of Urine Cultures Collected Out of the Total Number Expected to be Collected. [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Urine cultures were collected at baseline and monthly for six months. The total number of urine cultures collected out of the total number that were expected to be collected are shown.


Secondary Outcome Measures:
  • Number of Participants With E.Coli Isolated From Urine Culture [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Urine cultures were obtained at baseline and monthly for six months. Any participant that had E.coli isolated at least once is listed as meeting the outcome.

  • Number of Participants With >100,000 Colony Forming Units Per Milliliter of Any Organism Isolated From Urine Culture [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Urine cultures were obtained at baseline and monthly for 6 months. If a urine culture had >100,000 colony forming units per milliliter of any organism on any of the urine cultures obtained, the participant is noted as meeting the outcome.

Detailed Description:

Cranberry products represent a novel, non-antimicrobial method for prevention of UTI. There is evidence for a plausible mechanism and efficacy for UTI prevention in healthy premenopausal women. Limited clinical studies of cranberry products in elderly men and women have demonstrated reductions in bacteriuria but have not been of adequate size or quality to support the use of cranberry in this population or result in changes in patient care. Thus, a properly designed, definitive study demonstrating efficacy of cranberry in preventing UTI in this population is needed. However, before a large-scale, placebo-controlled trial can be justified, the complexities inherent to studying older nursing home residents need to be addressed. These include issues related to collecting uncontaminated urine samples, understanding the microbiology of UTI in this population, and devising an acceptable intervention regimen. The overall goal of this proposal is to conduct a prospective cohort pilot study that evaluates the feasibility of using cranberry to prevent UTI in nursing home residents. Each of the aims listed below is critical for the optimal design of a larger placebo-controlled, definitive trial of cranberry for prevention of UTI in nursing home residents and will provide the essential preliminary data for a future RO1 level grant application.
