Catheter-Associated Urinary Tract Infection Prevention

Catheter-associated urinary tract infections (CAUTIs) are the most common healthcare-associated infection and a significant target for quality improvement. CAUTI prevention focuses on two primary strategies: avoiding unnecessary catheter insertion and removing catheters as soon as they are no longer needed. CPHQ candidates should understand prevention approaches and quality measurement for CAUTI.

Appropriate Indications

The first line of CAUTI prevention is ensuring catheters are placed only for appropriate clinical indications. Accepted indications include acute urinary retention, accurate output measurement in critically ill patients, perioperative use for selected surgeries, management of urinary incontinence to promote healing of open wounds, and patient comfort at end of life. Convenience of nursing care and urine specimen collection are not appropriate indications.

Insertion Best Practices

When catheter placement is indicated, evidence-based insertion practices reduce infection risk. These include hand hygiene before insertion, use of sterile technique, proper perineal cleaning, use of the smallest appropriate catheter size, securing the catheter to prevent movement, and connecting to a closed drainage system. Standardized catheter insertion kits and training programs support consistent practice.

Maintenance and Removal

Ongoing catheter maintenance is essential for CAUTI prevention. Key practices include maintaining a closed drainage system, keeping the drainage bag below the level of the bladder, performing routine perineal hygiene, and avoiding routine catheter changes. Most importantly, daily assessment of continued catheter necessity should be performed, and catheters should be removed as soon as the clinical indication resolves.

Nurse-Driven Removal Protocols

Nurse-driven catheter removal protocols are a highly effective strategy for reducing catheter days and CAUTI rates. These protocols empower nurses to remove urinary catheters when specific criteria are met without requiring a physician order. Research demonstrates that nurse-driven protocols significantly reduce catheter utilization rates and CAUTI incidence.

Quality Measurement

CAUTI rates are reported to NHSN and publicly reported through CMS Hospital Compare. Metrics include the CAUTI standardized infection ratio, catheter utilization ratio (catheter days divided by patient days), and catheter days. Organizations should also track compliance with insertion indications, maintenance practices, and daily necessity assessments. These process measures help identify specific areas for improvement.
