Women over age 65 are being over-diagnosed with and over- treated for urinary tract infections, according to a new study.

Rhode Island Hospital researchers examined medical records of women over 65 who were diagnosed with a UTI during an ER visit. They found 57% had a urine culture that confirmed the diagnosis, yet 95% had antibiotics.

The researchers also noted inserting a temporary catheter into the bladder is a more accurate way to make a diagnosis compared to the “clean catch” method. 

Results were in the Journal of the American Geriatrics Society
