Taking cranberry capsules did not reduce urinary tract infections (UTIs) in older women living in nursing homes, a US randomised trial has shown.
UTIs are very common among nursing home residents: bacteriuria is detected in 25-50% of women living in nursing homes, and pyuria is present in 90% of these. Cranberry products have been of interest in preventing UTIs in this group of people, to reduce unnecessary use of antibiotics.
