Use of Indwelling Urinary Catheters in Nursing Homes: Implications for Quality Improvement Efforts

Catheter-associated Urinary Tract Infections-Online Questionnaire: Status Quo in Central European Urological Management of Catheter-associated Urinary Tract Infection

Background and objective

Catheter-associated urinary tract infections (CAUTIs) represent a significant burden in health care and its management is challenging. This study aims to assess and compare central European CAUTIs regarding diagnostics, treatment, and prophylaxis.

Methods

An anonymized online questionnaire was distributed among urologists in Austria, France, Germany, and Switzerland between January and October 2023, consisting of demographic questions on catheter management and diagnostics, treatment, and prophylaxis of CAUTIs. An analysis was performed per country. Comparisons were done with the Fisher's exact test (statistical significance with p < 0.05).

Key findings and limitations

Out of 423 participating urologists, most regularly performed catheter changes and managed catheter-related issues, except for French urologists. Swiss urologists tended to change the catheter after a longer interval. In France, a higher estimated number of CAUTIs were observed. Diagnostic symptoms and measures varied significantly between countries. French urologists prescribed more antimicrobials per patient and administered longer treatment regimens. The choice of antimicrobial agents differed notably for nonfebrile and febrile CAUTIs, with cotrimoxazole/nitrofurantoin being common for nonfebrile cases and cephalosporin/amoxicillin for febrile ones. Follow-up protocols were similar among urologists, while prophylactic measures showed variations.

Conclusions and clinical implications

CAUTI management varied notably across countries in terms of diagnostics, treatment, and prophylaxis. Discrepancies in antimicrobial therapy could be influenced by local resistance rates; yet, nonrecommended drugs and prolonged regimens, as compared with guideline recommendations, were common. This trend, along with inappropriate diagnostics and prophylaxis, may increase antimicrobial resistance and CAUTI morbidity. This study emphasizes the necessity for diagnostic and antimicrobial stewardship interventions, and proper training in CAUTI management.

Patient summary

In this questionnaire-based study examining the clinical practices for managing urinary tract infections in patients with bladder catheters (CAUTIs), significant disparities were observed among European urologists regarding diagnosis, treatment, and prophylaxis. These findings underscore the critical need for clear guidelines and comprehensive training in CAUTI management.

Prevalence of indwelling urinary catheters in nursing home residents: Systematic review

BACKGROUND

This systematic review examines the prevalence of indwelling urinary catheters in nursing home residents.

METHODS

MEDLINE via PubMed, CINAHL, and EMBASE were searched from inception to 9 August 2022. Cross-sectional studies and longitudinal studies with cross-sectional analyses reporting catheter prevalence in nursing home residents were identified and summarized descriptively. Study quality was assessed using the Joanna Briggs Institute's tool.

RESULTS

Sixty-seven studies (92.5 % cross-sectional) were included. The reported number of included residents ranged from 73 to 110,656. The median catheter prevalence was 7.3 % (interquartile range 4.3-10.1 %; n = 65 studies). It was higher in Germany (10.2 % [9.7-12.8 %]; n = 15) than in the United States of America (9.3 % [6.3-11.9 %]; n = 9), United Kingdom (6.9 % [4.8-8.5 %]; n = 7), and Sweden (7.3 % [6.4-7.9 %]; n = 6). Furthermore, it was higher among men (17.0 % [16.0-26.0 %]) than among women (5.3 % [4.0-9.5 %]) (n = 9). Only one study investigated differences by age. The prevalence was higher for transurethral (5.7 % [5.6-7.2 %]; n = 12) than for suprapubic (1.2 % [0.6-2.5 %]; n = 13) catheters. Most catheterized residents were long-term catheterized (n = 6) and had their catheter changed within 3 months (n = 2). Symptomatic urinary tract infections were more common among catheterized than among non-catheterized residents (n = 4).

DISCUSSION

Catheter prevalence in nursing home residents varies between studies and countries. Prevalence differences by sex, age, and catheter type as well as duration of catheterization, catheter change intervals, and catheter-associated urinary tract infections are rarely reported because most studies do not primarily focus on catheters. Future studies should focus on the circumstances of urinary catheter use and care in nursing home residents.

Health Care-Associated Infections in Older Adults: Epidemiology and Prevention

Health care-associated infections (HAIs) are a global public health threat, which disproportionately impact older adults. Host factors including aging-related changes, comorbidities, and geriatric syndromes, such as dementia and frailty, predispose older individuals to infection. The HAI risks from medical interventions such as device use, antibiotic use, and lapses in infection control follow older adults as they transfer among a network of interrelated acute and long-term care facilities. Long-term care facilities are caring for patients with increasingly complex needs, and the home-like communal environment of long-term care facilities creates distinct infection prevention challenges.

Racial Differences in Urinary Catheter Use Among Female Nursing Home Residents

OBJECTIVE

To assess racial differences in prevalence of indwelling urinary catheterization and intermittent catheterization among female NH residents in the United States (US).

METHODS

We performed a cross-sectional analysis using the 2019 Minimum Data Set 3.0 and developed a multivariable logistic regression model to examine the association between catheter use and race. Moderation analyses were performed to clarify significant associations.

RESULTS

Our study cohort was composed of 597,966 women, who were predominantly of White race with a median age of 80 years. Eight percent (n=47,799) of female residents had indwelling catheters, and 0.5% (n=2,876) used intermittent catheterization. Black residents had a 7% lower odds of having an indwelling catheter (aOR 0.93, 95% CI 0.90-0.96), and a 38% lower odds of utilizing intermittent catheterization (aOR 0.62, 95% CI 0.54-0.71) compared to White residents when controlling for common factors associated with catheter use. In moderation analyses, Black residents with age under 80 years and BMI of 35 kg/m2 or greater were less likely to have an indwelling catheter than age- and BMI-matched White residents.

CONCLUSION

Racial differences in both indwelling and intermittent catheterization prevalence exist in female NH residents. These disparities should be further clarified to reduce bias in NH care.

Diagnosis, Treatment, and Prevention of Urinary Tract Infections in Post-Acute and Long-Term Care Settings: A Consensus Statement From AMDA's Infection Advisory Subcommittee

The diagnosis and management of urinary tract infections (UTIs) among residents of post-acute and long-term care (PALTC) settings remains challenging. Nonspecific symptoms, complex medical conditions, insufficient awareness of diagnostic criteria, and unnecessary urine studies all contribute to the inappropriate diagnosis and treatment of UTIs in PALTC residents. In 2017, the Infection Advisory Subcommittee at AMDA-The Society for Post-Acute and Long-Term Care Medicine convened a workgroup comprised of experts in geriatrics and infectious diseases to review recent literature regarding UTIs in the PALTC population. The workgroup used evidence as well as their collective clinical expertise to develop this consensus statement with the goal of providing comprehensive guidance on the diagnosis, treatment, and prevention of UTIs in PALTC residents. The recommendations acknowledge limitations inherent to providing medical care for frail older adults, practicing within a resource limited setting, and prevention strategies tailored to PALTC populations. In addition, the consensus statement encourages integrating antibiotic stewardship principles into the policies and procedures used by PALTC nursing staff and by prescribing clinicians as they care for residents with a suspected UTI.

Restoring trust: COVID-19 and the future of long-term care in Canada

The Royal Society of Canada Task Force on COVID-19 was formed in April 2020 to provide evidence-informed perspectives on major societal challenges in response to and recovery from COVID-19. The Task Force established a series of working groups to rapidly develop policy briefings, with the objective of supporting policy makers with evidence to inform their decisions. This paper reports the findings of the COVID-19 Long-Term Care (LTC) working group addressing a preferred future for LTC in Canada, with a specific focus on COVID-19 and the LTC workforce. First, the report addresses the research context and policy environment in Canada’s LTC sector before COVID-19 and then summarizes the existing knowledge base for integrated solutions to challenges that exist in the LTC sector. Second, the report outlines vulnerabilities exposed because of COVID-19, including deficiencies in the LTC sector that contributed to the magnitude of the COVID-19 crisis. This section focuses especially on the characteristics of older adults living in nursing homes, their caregivers, and the physical environment of nursing homes as important contributors to the COVID-19 crisis. Finally, the report articulates principles for action and nine recommendations for action to help solve the workforce crisis in nursing homes.

Factors associated with long-term urinary catheterisation and its impact on urinary tract infection among older people in the community: a population-based observational study in a city in Japan

OBJECTIVES

This study aimed to identify factors associated with long-term urinary catheterisation (LTUC) in community-dwelling older adults and to evaluate the risk of urinary tract infection (UTI) among people with LTUC.

DESIGN

Population-based observational study.

SETTING

Medical and long-term care insurance claims data from one municipality in Japan.

PARTICIPANTS

People aged ≥75 years living at home who used medical services between October 2012 and September 2013 (n=32 617).

OUTCOME MEASURES

(1) Use of LTUC, defined as urinary catheterisation for at least two consecutive months, to identify factors associated with LTUC and (2) the incidence of UTI, defined as a recorded diagnosis of UTI and prescription of antibiotics, in people with and without LTUC.

RESULTS

The 1-year prevalence of LTUC was 0.44% (143/32 617). Multivariable logistic regression analysis showed that the male sex, older age, higher comorbidity score, previous history of hospitalisation with in-hospital use of urinary catheters and high long-term care need level were independently associated with LTUC. The incidence rate of UTI was 33.8 and 4.7 per 100 person-years in people with and without LTUC, respectively. According to multivariable Poisson regression analysis, LTUC was independently associated with UTI (adjusted rate ratio 2.58, 95% CI 1.68 to 3.96). Propensity score-matched analysis yielded a similar result (rate ratio 2.41, 95% CI 1.45 to 4.00).

CONCLUSIONS

We identified several factors associated with LTUC in the community, and LTUC was independently associated with the incidence of UTI.

A National Implementation Project to Prevent Catheter-Associated Urinary Tract Infection in Nursing Home Residents

IMPORTANCE

Catheter-associated urinary tract infection (UTI) in nursing home residents is a common cause of sepsis, hospital admission, and antimicrobial use leading to colonization with multidrug-resistant organisms.

OBJECTIVE

To develop, implement, and evaluate an intervention to reduce catheter-associated UTI.

DESIGN, SETTING, AND PARTICIPANTS

A large-scale prospective implementation project was conducted in community-based nursing homes participating in the Agency for Healthcare Research and Quality Safety Program for Long-Term Care. Nursing homes across 48 states, Washington DC, and Puerto Rico participated. Implementation of the project was conducted between March 1, 2014, and August 31, 2016.

INTERVENTIONS

The project was implemented over 12-month cohorts and included a technical bundle: catheter removal, aseptic insertion, using regular assessments, training for catheter care, and incontinence care planning, as well as a socioadaptive bundle emphasizing leadership, resident and family engagement, and effective communication.

MAIN OUTCOMES AND MEASURES

Urinary catheter use and catheter-associated UTI rates using National Healthcare Safety Network definitions were collected. Facility-level urine culture order rates were also obtained. Random-effects negative binomial regression models were used to examine changes in catheter-associated UTI, catheter utilization, and urine cultures and adjusted for covariates including ownership, bed size, provision of subacute care, 5-star rating, presence of an infection control committee, and an infection preventionist.

RESULTS

In 4 cohorts over 30 months, 568 community-based nursing homes were recruited; 404 met inclusion criteria for analysis. The unadjusted catheter-associated UTI rates decreased from 6.78 to 2.63 infections per 1000 catheter-days. With use of the regression model and adjustment for facility characteristics, the rates decreased from 6.42 to 3.33 (incidence rate ratio [IRR], 0.46; 95% CI, 0.36-0.58; P < .001). Catheter utilization was 4.5% at baseline and 4.9% at the end of the project. Catheter utilization remained unchanged (4.50 at baseline, 4.45 at conclusion of project; IRR, 0.95; 95% CI, 0.88-1.03; P = .26) in adjusted analyses. The number of urine cultures ordered for all residents decreased from 3.49 per 1000 resident-days to 3.08 per 1000 resident-days. Similarly, after adjustment, the rates were shown to decrease from 3.52 to 3.09 (IRR, 0.85; 95% CI, 0.77-0.94; P = .001).

CONCLUSIONS AND RELEVANCE

In a large-scale, national implementation project involving community-based nursing homes, combined technical and socioadaptive catheter-associated UTI prevention interventions successfully reduced the incidence of catheter-associated UTIs.

Comparing Catheter-Associated Urinary Tract Infection Prevention Programs Between Veterans Affairs Nursing Homes and Non-Veterans Affairs Nursing Homes

OBJECTIVE The impact of healthcare system integration on infection prevention programs is unknown. Using catheter-associated urinary tract infection (CAUTI) prevention as an example, we hypothesize that US Department of Veterans Affairs (VA) nursing homes have a more robust infection prevention infrastructure due to integration and centralization compared with non-VA nursing homes. SETTING VA and non-VA nursing homes participating in the AHRQ Safety Program for Long-Term Care collaborative. METHODS Nursing homes provided baseline information about their infection prevention programs to assess strengths and gaps related to CAUTI prevention via a needs assessment questionnaire. RESULTS A total of 353 of 494 nursing homes from 41 states (71%; 47 VA and 306 non-VA facilities) responded. VA nursing homes reported more hours per week devoted to infection prevention-related activities (31 vs 12 hours; P<.001) and were more likely to have committees that reviewed healthcare-associated infections. Compared with non-VA facilities, a higher percentage of VA nursing homes reported tracking CAUTI rates (94% vs 66%; P<.001), sharing CAUTI data with leadership (94% vs 70%; P=.014) and with nursing personnel (85% vs 56%, P=.003). However, fewer VA nursing homes reported having policies for appropriate catheter use (64% vs 81%; P=.004) and catheter insertion (83% vs 94%; P=.004). CONCLUSIONS Among nursing homes participating in an AHRQ-funded collaborative, VA and non-VA nursing homes differed in their approach to CAUTI prevention. Best practices from both settings should be applied universally to create an optimal infection prevention program within emerging integrated healthcare systems.
