PICOT and Statement Literature Search Nursing Practice Problem
Doctors use urinary catheters to empty urine from patients who have impaired urinary systems. Such patients might suffer from kidney failure due to pressure exerted on their kidneys, which can cause permanent damage. However, urinary catheters may cause potential complications, including urinary tract infections (UTIs), kidney damage, urethral injury, bladder stones, blood in the urine, septicemia, and allergic reactions. Research indicates that most patients with indwelling urinary catheters develop UTIs, especially when the catheters are used for prolonged periods.
The PICOT question focuses on older pediatric patients aged 65 and above and examines the influence of the duration of catheter use on the risk of catheter-associated urinary infections (CAUTIs). Specifically: "For pediatric patients 65 years and older (P), how does the use of catheters for a longer time (I) compared to shorter durations (C) influence the risk of CAUTI (O) during the first ten weeks of indwelling catheter use (T)?" The purpose is to determine strategies to minimize infection risks associated with long-term catheterization, as prolonged use increases the likelihood of infections and other complications.

Urinary catheterization is a common medical procedure used to manage urinary retention, monitor urine output, or facilitate treatment in patients with impaired urinary function. Despite its utility, indwelling urinary catheters pose significant risks, particularly urinary tract infections (UTIs), which can lead to severe morbidity, increased healthcare costs, and in some instances, mortality. This paper discusses the implications of prolonged catheter use in older patients, the pathophysiology behind CAUTIs, and evidence-based interventions to reduce infection rates based on a comprehensive review of recent literature.
Introduction
Urinary catheterization has been integral to urological management for decades, yet its use is increasingly scrutinized due to associated risks. Indwelling urinary catheters, or Foley catheters, are susceptible to microbial colonization, which can lead to CAUTIs. Older adults, especially those over 65, are particularly vulnerable due to age-related immune decline, comorbidities, and reduced mobility, which further complicate infection control efforts. Given the high incidence and adverse outcomes associated with CAUTIs, it is critical to evaluate the influence of catheter duration and implement effective infection prevention strategies.
Pathophysiology of CAUTIs
CAUTIs predominantly result from microbial introduction into the bladder via the catheter. Pathogens may originate from endogenous flora or external contamination. Flores-Mireles et al. (2015) elucidate that bacteria can ascend periurethrally or intraluminally, forming biofilms on the catheter surface. These biofilms shield microorganisms from host defenses and antimicrobials, making infections persistent once established. The risk of bacteriuria increases by approximately 10% daily, reaching nearly 100% in patients with catheters in place for a month. Prolonged catheterization fosters biofilm formation and microbial resistance, escalating the difficulty of treatment.
Impacts of Prolonged Catheterization
Extended use of indwelling catheters correlates with higher incidences of UTIs, urethral trauma, and systemic infections. Lee et al. (2016) show that patients with catheter durations exceeding seven days exhibit significantly increased risk of bacteriuria and symptomatic UTIs. Such infections not only prolong hospitalization but also predispose patients to sepsis, kidney injury, and increased healthcare costs. Furthermore, excessive catheterization contributes to antimicrobial resistance through selective pressure and biofilm-associated microbial persistence.
Strategies for Prevention
Evidence-based guidelines recommend several measures to mitigate CAUTI risk. Meddings et al. (2014) emphasize the importance of adhering to aseptic techniques during insertion, maintaining a closed drainage system, and timely removal of catheters. They suggest that clinicians should avoid routine catheterization unless absolutely necessary and should remove or replace catheters within 2-3 weeks for those requiring long-term use.
Proper catheter care includes maintaining unobstructed drainage, preventing backflow, and ensuring the insertion site remains clean and dry. Regular staff training on sterile techniques and adherence to institutional policies have demonstrated reductions in CAUTI rates (Conway & Larson, 2012). Furthermore, implementing checklists and standardized protocols for catheter maintenance enhances compliance and minimizes breaches in infection control practices.
Evidence-Based Practice Change
Conway and Larson (2012) advocate for strategic changes in clinical practice based on current guidelines. They recommend that healthcare providers perform daily assessments of catheter necessity, encouraging prompt removal when no longer indicated. Use of antimicrobial-impregnated catheters and antimicrobial stewardship programs have also shown promise in reducing bacteriuria rates. Training nurses and physicians in aseptic insertion techniques, coupled with ongoing education and audits, significantly decreases CAUTI incidence.
In pediatric and older adult populations, special precautions are warranted. Lee et al. (2016) highlight that shorter catheterization durations and comprehensive staff training are particularly vital for vulnerable groups. These practices, aligned with guidelines from the Centers for Disease Control and Prevention (CDC), contribute to safer patient outcomes.
Conclusion
Prolonged indwelling catheter use remains a significant risk factor for CAUTIs, especially in older, immunocompromised patients. Evidence underscores the necessity for judicious catheter use, strict adherence to aseptic techniques during insertion, and prompt removal to minimize infection risks. Implementing standardized protocols rooted in current research and guidelines can substantially reduce CAUTI incidence, improve patient safety, and decrease healthcare-associated costs. Continuous education, surveillance, and quality improvement initiatives are essential components of an effective infection prevention strategy in healthcare settings.
