Using statistical process control charts to measure changes from a nurse-driven protocol to remove urinary catheters.

Implementing a nurse-driven protocol (NDP) to remove indwelling urinary catheters is a strategy to reduce catheter-associated urinary tract infections (CAUTI). The purpose of this project was to implement a comprehensive NDP to reduce indwelling urinary catheter utilization and CAUTI rates at a large academic health system.

Statistical process control (SPC) charts, a quality improvement method, was used to identify special cause variation. A formal protocol was developed to provide guidance for nurses to remove IUCs when no longer indicated. Changes were also made within the electronic health record.

Signals of improvement were not noted on the SPC charts for urinary catheter utilization or CAUTI rates. The frequency with which the NDP was documented (process measure) was assessed, showing it is used approximately 600 times each month. Of those catheters removed by the NDP, an average of 6% were reinserted within 48 hours (balancing measure).

Our findings differed from other literature as we did not see a reduction in urinary catheter utilization after implementing a NDP. However, our project adds to the literature as we also evaluated process and balancing measures.

A NDP for urinary catheter removal provides nurses with the autonomy to remove catheters when no longer indicated; however, other interventions should be added to a comprehensive CAUTI-prevention program.
