The Effect of Surface Acoustic Waves on Bacterial Load and Preventing Catheter- associated Urinary Tract Infections (CAUTI) in Long Term Indwelling Catheters

Abstract

The authors evaluate a novel Surface Acoustic Wave Actuator and its effect on preventing CAUTI. This is a double blinded randomized control trial, of the Uroshield™ device. 55 patients in a skilled nursing facility chain being treated with long term indwelling catheters were evaluated. There was a significant difference between the treated group and the placebo group in the number of Colony Forming Units present upon evaluation, as well as on the number of treated UTI’s. The effect lasted beyond the time of active treatment.
