Eliminating Catheter-Associated Urinary Tract Infections in a Pediatric Cardiac ICU

To eliminate catheter-associated urinary tract infections in a pediatric cardiac ICU.

Quality improvement methodology.

Twenty-five bed cardiac ICU in a quaternary freestanding children's hospital.

All patients with an indwelling urinary catheter admitted to the cardiac ICU.

Catheter-associated urinary tract infection was defined according to National Healthcare Safety Network criteria. Failure modes and effects analysis and Pareto charts were used to determine etiology of process failures. We implemented a team-based multi-interventional approach in 2012 using the Model for Improvement, which included as follows: 1) establish indications for inserting and/or maintaining bladder catheterization, 2) standardization of maintenance care for the indwelling urinary catheters, 3) protocol for management of the leaking urinary catheters, 4) incorporation of urinary catheter days and prompts for removal in daily rounds, and 5) review of all cases of prolonged indwelling urinary catheter use (> 3 d). Process control charts were used to evaluate change.

From 2011 to 2018, we showed an early and sustained improvement in catheter-associated urinary tract infection prevention standards compliance from 44% to 96% (52% improvement). These interventions showed a reduction and then elimination of catheter-associated urinary tract infections from January 2012 to the present day, despite fluctuations in total indwelling urinary catheter days.

Utilization of quality improvement methodology allowed us to identify components of care that contributed to catheter-associated urinary tract infections. After addressing these issues, we noted a substantial reduction and then elimination of catheter-associated urinary tract infections in our pediatric cardiac ICU. Widely disseminating these interventions across multiple pediatric hospitals to determine the ability to achieve similar results are important next steps.
