  Purpose

Urinary tract infection (UTI) is the most common infection in nursing home residents, and bacteriuria is the greatest trigger for antimicrobial therapy in the nursing home setting. The primary aim of this study is to test the efficacy of two oral cranberry capsules per day in the prevention of bacteriuria in female nursing home residents. The secondary aim is to compare the occurrence of urinary tract specific symptoms in the cranberry capsule versus placebo groups. These aims will be accomplished by conducting a double blind randomized placebo controlled efficacy trial of two oral cranberry capsules daily versus placebo in a cohort of Connecticut female nursing home residents.

Primary Outcome Measures:
  • Number of urine cultures with bacteriuria (>100,000 cfu/ml) plus pyuria (>10 WBC) [ Time Frame: One year ] [ Designated as safety issue: No ]
    Clean catch urine cultures and urinalyses will be obtained every two months for each participant for study purposes.


Secondary Outcome Measures:
  • Number of episodes of UTI [ Time Frame: One year ] [ Designated as safety issue: No ]
    UTI episodes that are recorded in the medical record by the primary provider will be collected by chart review.

  • Number of hospitalizations [ Time Frame: One year ] [ Designated as safety issue: Yes ]
  • Number of deaths [ Time Frame: One year ] [ Designated as safety issue: Yes ]
  • Number of antibiotic prescriptions [ Time Frame: One year ] [ Designated as safety issue: No ]
    Chart review will be performed to determine the names and duration of antibiotic prescriptions prescribed by the primary provider on each participant.

  • Number of multi-drug resistant organisms in each participant [ Time Frame: One year ] [ Designated as safety issue: No ]
    Chart review will be performed to determine if multi-drug resistant organisms were isolated from clinical samples (e.g., sputum, urine, blood cultures) submitted by the primary provider.


Other Outcome Measures:
  • Number of adverse events in participants [ Time Frame: One year ] [ Designated as safety issue: Yes ]
  • Adherence to capsule intake by all participants [ Time Frame: One year ] [ Designated as safety issue: No ]
