Review of Evidence-Based Practice to Decrease CAUTIs
Impact of the Problem on the Patient
Catheter-associated urinary tract infections (CAUTIs) continue to be a significant source of preventable harm for hospitalized patients across the United States. Research shows that 15% to 25% of inpatients will require an indwelling urinary catheter during their hospital stay, and about 75% of hospital-acquired urinary tract infections (HAUTIs) are related to catheter use (Shadle et al., 2021). The insertion of these catheters substantially increases the risk of bacterial colonization, leading to infections that extend hospital stays, increase patient morbidity and mortality, and generate higher treatment costs—estimated at around $14,000 per patient affected by CAUTIs (Shadle et al., 2021).
Patients suffering from CAUTIs may experience symptoms such as pain, discomfort, and fever, with the potential for severe complications like sepsis. These infections delay recovery and adversely affect the patient’s overall quality of life. Consequently, preventing CAUTIs is crucial for improving clinical outcomes, enhancing patient satisfaction, and reducing unnecessary healthcare costs. Implementing effective infection control protocols is essential not only for patient safety but also to nurture a healthcare culture that prioritizes quality and safety.
Impact of the Problem on the Organization
From the healthcare institution’s perspective, CAUTIs are classified as hospital-acquired infections (HAIs), which must be reported to regulatory bodies such as the National Healthcare Safety Network (NHSN) and the Centers for Medicare & Medicaid Services (CMS). These infections impact critical hospital performance metrics, reimbursement schemes, and accreditation processes (Rubi, Mudey, & Kunjalwar, 2022).
Healthcare organizations invest significant resources in infection control measures, including ongoing staff training and surveillance aimed at reducing CAUTI rates. Successfully lowering these rates aligns with national patient safety goals and value-based purchasing programs, which incentivize improved patient outcomes and reduced readmissions. Ultimately, reducing CAUTIs enhances hospital reputation, operational efficiency, and cost savings by minimizing financial penalties and shortening patients’ length of stay.

Daily Bathing with 4% Chlorhexidine Gluconate in Intensive Care Settings: A Randomized Controlled Trial
Background Introduction
Palloto et al. (2019) conducted a randomized controlled trial (RCT) to assess the effectiveness of daily bathing with 4% chlorhexidine gluconate (CHG) in preventing hospital-acquired infections, especially within intensive care units (ICUs). This study was driven by growing evidence that CHG decreases microbial colonization and transmission of multidrug-resistant organisms, thereby lowering infection rates such as CAUTIs and ventilator-associated pneumonia (VAP).
Methodology
The study was a single-blind, parallel-group RCT conducted between August 2015 and April 2016 in both an ICU and a post-cardiac surgery ICU (PC-ICU). Eligible participants were adults aged 18 years or older who were admitted for at least one night. Patients were randomly assigned to receive daily CHG bathing or standard bathing care (Palloto et al., 2019).
Level of Evidence
According to the Johns Hopkins Nursing Evidence-Based Practice (JHNEBP) model, this study is classified as Level I evidence, representing the highest quality research.
Data Analysis
Statistical analysis was performed using R software, with significance set at p < 0.05. Tests including the Kolmogorov–Smirnov test assessed data normality, and Mann–Whitney and chi-square tests with Yate’s correction compared groups (Palloto et al., 2019).
Ethical Considerations
Ethical approval was obtained from the institution’s review board before data collection. Written informed consent was secured from capable participants, with consent waivers applied as necessary. Patients unable to consent initially were re-consented once able, in line with the Declaration of Helsinki (Palloto et al., 2019).
Quality Rating
Using the JHNEBP appraisal tool, this trial was rated Grade A (High Quality), reflecting a rigorous design, ethical soundness, and reliable statistical methods.
Analysis of Results and Conclusions
The trial found that daily CHG bathing significantly reduced hospital-acquired infections, including CAUTIs and VAP, without increasing adverse events or mortality. Across the study, 108 infections occurred among 91 patients, with CAUTI rates dropping to 4.9 per 1,000 patient-days (Palloto et al., 2019). This provides strong evidence supporting the clinical efficacy and safety of daily CHG bathing in ICU settings.
Alignment to the EBP Question
This research directly supports the evidence-based practice question by confirming daily CHG bathing as an effective intervention to reduce CAUTI incidence in hospitalized patients (Palloto et al., 2019).

Short-Term Urinary Catheters and Their Risks: An Integrated Systematic Review
Background Introduction
Gyesi-Appiah, Brown, and Clifton (2020) performed an integrated systematic review focusing on risks associated with short-term urinary catheterization. They found that the risk of urinary tract infection (UTI) increases by 3% to 7% each day a catheter remains in place.
Type of Evidence
The review synthesized findings from 12 primary studies conducted between 2013 and 2018, analyzing urinary catheter use and related complications (Gyesi-Appiah et al., 2020).
Level of Evidence
This integrative review is categorized as Level V evidence under the JHNEBP model, representing a synthesis of non-experimental studies.
Quality Rating
The review earned a Grade B (Good Quality) rating, reflecting a thorough search strategy and methodological rigor, with sources from databases like CINAHL, Medline, and the British Nursing Index (Gyesi-Appiah et al., 2020).
Authors’ Recommendations
The authors strongly recommend removing urinary catheters promptly once medically unnecessary, emphasizing that early removal is critical in lowering CAUTI rates—supporting the current EBP question.
Recommended Practice Change
Research and review findings consistently support implementing daily CHG bathing combined with timely catheter removal as effective strategies to reduce CAUTI incidence. To achieve sustainable outcomes, hospitals should adopt a multifaceted infection prevention bundle. This approach includes continuous staff education, routine auditing, and adherence monitoring.
Demonstrating both clinical efficacy and cost benefits will encourage stakeholder engagement and facilitate institutional acceptance of these practices.
Key Stakeholders
| Stakeholder | Role and Importance |
|---|---|
| Patients | Central beneficiaries; experience fewer infections, reduced hospital stays, and improved comfort. |
| Nurses | Key personnel in implementing CHG bathing and monitoring catheter use. |
| Physicians | Responsible for ordering catheter insertions and ensuring timely removal. |
| Hospital Administration | Oversees compliance, infection reporting, and financial evaluations related to infection control efforts. |
Barriers to Implementation
Significant barriers include staff workload and high patient-to-nurse ratios, which may delay catheter removal. Patient comfort preferences and clinical uncertainty about catheter necessity can also limit adherence to infection control protocols.
Strategies to Overcome Barriers
Hospitals can address these challenges through targeted staff education highlighting infection prevention benefits, daily interdisciplinary safety briefings, and enhanced communication among care teams. Implementing continuous feedback, performance monitoring, and recognition programs will promote staff engagement and compliance (Palloto et al., 2019; Gyesi-Appiah et al., 2020).
Indicators to Measure Outcomes
Key metrics for evaluating CAUTI prevention efforts include:
| Indicator | Description |
|---|---|
| Audit Frequency | Documentation of daily CHG bathing and catheter duration. |
| Infection Rates | Number of CAUTI cases per 1,000 catheter-days. |
| System Metrics | Readmission rates and reimbursement data via CMS and NHSN monitoring. |
Continuous assessment ensures ongoing quality improvement and the effectiveness of infection prevention protocols.
Conclusion
CAUTIs remain a preventable yet serious healthcare issue affecting both patient well-being and hospital performance. Evidence supports that daily chlorhexidine bathing alongside timely catheter removal substantially reduces CAUTI rates in hospitalized patients. Maintaining these improvements requires ongoing interprofessional collaboration, patient engagement, and diligent monitoring to foster a culture of safe, high-quality care.
