Effect of Active Drain Line Clearance on Catheter-Associated Bacteriuria

Effect of Active Drain Line Clearance With or Without Silver on Catheter-Associated Bacteriuria (The CAB Study)

Catheter-associated urinary tract infections (CAUTI) are the most common nosocomial infections in critically ill patients and are responsible for high morbidity rates, increased hospital stays and associated costs.

The purpose of this study is to evaluate whether active drain line clearance by the Accuryn Monitoring System reduces the incidence of CAUTI in hospitalized patients requiring catheters.

Urinary tract infection (UTI) is the most common healthcare associated infection (HAI) acquired in hospitals and is estimated to account for approximately 13% of hospital infections in the United States, of which 75% are associated with indwelling urinary catheters. It is estimated that between 12-16% adult inpatients will receive an indwelling urinary catheter during their hospital stay. The rate of catheter-associated UTI (CAUTI) are highest in burn ICUs, followed by inpatient medical wards and neurosurgical ICUs.

The purpose of this study is to evaluate whether active drain line clearance by the Accuryn Monitoring System reduces the incidence of bacteriuria and/or CAUTI in patients requiring catheters for more than 72 hours. This study will also evaluate the efficacy in reducing bacteriuria of the Accuryn silver fabricated silicone catheters.
