Cranberry Products for the Prevention of Catheter-Associated Urinary Tract Infections

Abstract

In this review, we examine the current literature regarding the use of cranberry and other complimentary methods for the prevention of catheter-associated urinary tract infections (CAUTIs). Some studies have suggested cranberry products may have a positive effect in reducing the incidence of CAUTIs in patients with normal bladder function receiving short-term catheterization, while other studies have failed to show the benefits of cranberry products for the reduction of CAUTIs. While there is some data suggesting cranberry-derived products may reduce CAUTIs in specific patient populations, there is currently overall insufficient clinical data to recommend broad usage of cranberry products for the reduction of CAUTIs. Many of the studies reviewed have significant limitations in size, design, and lack standardization.
