Reducing CAUTI Rates in the ICU Using the PDSA Cycle
This paper presents a quality improvement (QI) initiative designed to reduce catheter-associated urinary tract infections (CAUTI) in the intensive care unit (ICU). Using the Plan-Do-Study-Act (PDSA) cycle, a multidisciplinary team of nurses and physicians developed and implemented evidence-based insertion and maintenance protocols, including catheter necessity reviews, hand hygiene standards, aseptic techniques, and alternative catheter options. Following implementation, compliance rose from 55% to 100%, and CAUTI rates dropped from 7.6 to 3.9 infections per 1,000 device days. The paper also outlines recommendations for a second PDSA cycle aimed at achieving the ultimate goal of zero CAUTI.

What makes this paper effective
- The paper follows a clear, logical structure that mirrors the PDSA cycle itself, making it easy to trace the QI process from planning through evaluation.
- Quantitative outcomes (compliance rising from 55% to 100%; CAUTI rates dropping from 7.6 to 3.9 per 1,000 device days) provide concrete evidence of improvement and strengthen the argument.
- The Act Phase goes beyond reporting results by offering specific, actionable recommendations for a subsequent PDSA cycle, demonstrating forward-thinking QI thinking.
Key academic technique demonstrated
This paper effectively uses an established improvement framework — the PDSA cycle — as both its organizational structure and its analytical lens. By anchoring each section to a phase of the cycle, the writer demonstrates how quality improvement methodology translates into real clinical practice, grounding recommendations in cited evidence rather than opinion.
Structure breakdown
The paper opens with a brief introduction establishing the clinical problem and the goal. Four body sections map directly onto the PDSA phases: the Plan section details protocol design, the Do section covers training and rollout, the Study section reports compliance and infection rate data, and the Act section proposes five concrete next steps. A short conclusion synthesizes the outcome and emphasizes the iterative nature of QI work. The paper is supported by three peer-reviewed citations.
Introduction
Catheter-associated urinary tract infections (CAUTI) are among the most prevalent hospital-acquired infections, contributing significantly to morbidity and mortality among patients. The most common causes of CAUTI include extended periods of catheter use and poor catheter care (Rubi et al., 2022). To address this issue, a quality improvement (QI) initiative was developed and implemented by a multidisciplinary team of nurses and physicians using the Plan-Do-Study-Act (PDSA) cycle. The primary goal was to reduce CAUTI rates in the ICU by 25% within six months, with the ultimate goal of eliminating CAUTI altogether.
Plan Phase: Developing Evidence-Based Protocols
The team collaborated to develop a plan consisting of guidelines for when catheter insertion is clinically necessary, alternatives such as condom catheters and PureWick devices, and maintenance standards. Maintenance standards included daily review of continued catheter necessity, hand hygiene, proper positioning (below bladder level and off the floor), regular drainage bag evacuation, and aseptic techniques for sampling at the port. These guidelines were grounded in evidence-based best practices (Lim, 2023).
Do Phase: Implementation and Staff Training
The approved protocols and care bundles were implemented across the ICU, and all staff members participated in training on the new procedures. Training ensured that every staff member understood the new protocols, the rationale behind them, and the importance of consistent adherence.
Study Phase: Monitoring Compliance and Outcomes
An infection preventionist conducted daily rounds during the first two weeks post-implementation to monitor compliance and address staff questions. Compliance with the new insertion and maintenance protocols rose from 55% to 100%. The impact of these changes was reflected in monthly CAUTI rates, which decreased from 7.6 infections per 1,000 device days to 3.9 infections per 1,000 device days.
Conclusion
The first PDSA cycle saw meaningful progress in reducing CAUTI rates in the ICU, but the ultimate goal of zero CAUTI was not reached and still requires ongoing effort. The recommendations outlined for the next cycle are intended to strengthen the intervention and improve outcomes. As with all quality improvement work, continued evaluation and refinement will be necessary in each subsequent PDSA cycle.
