Reducing catheter-associated urinary tract infection in high dependency unit: an eighteen-month quality improvement intervention study period.

ABSTRACT:

Background

The urinary catheter usually leads to a catheter-associated urinary tract infection (CAUTI) contributing to further morbidity and mortality. There is very limited data on the CAUTI incidence rate in high-dependency units (HDUs) in the Kingdom of Saudi Arabia. The institutional CAUTI incidence rate in HDU was six times higher compared to the United States National Healthcare Safety Network (US-NHSN) in 2021.

Objective

To reduce 50% CAUTI incidence rate by the end of 2022.

Method

A prospective study was conducted in tertiary HDU from January 2022 to June 2023. A gap analysis was assessed between the hospital practices and the Society Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA/IDSA) basic recommendations. The Kotter and Rathgebers' changing behavior model was applied at the beginning of the project. Formal education and prevention of CAUTI were applied using the National Strategy Model. Surveillance and statistical data analysis were carried out using US-NHSN guidelines.

Results

The overall CAUTI incidence rate declined from 7.07- to 3.57/1000 urinary catheter days despite of significant increase in the utilization ratio from 0.79 to 0.94 (P value 0.0001). The compliance rate of the bundle CAUTI prevention was improved and sustained above 90%. A CAUTI incidence rate reduction was observed following the combination of the changing behavior and SHEA/IDSA of CAUTI prevention models over 18 months.

Conclusion

We assumed the combination of the changing behavior and the prevention models for a long period is useful in reducing the CAUTI incidence rate and possibly applied to reduce other healthcare-associated infections.

Project description:IntroductionDespite advances in infection prevention and control, catheter-associated urinary tract infections (CAUTIs) are common and remain problematic. A number of measures can be taken to reduce the risk of CAUTI in hospitals. Appropriate urinary catheter insertion procedures are one such method. Reducing bacterial colonisation around the meatal or urethral area has the potential to reduce CAUTI risk. However, evidence about the best antiseptic solutions for meatal cleaning is mixed, resulting in conflicting recommendations in guidelines internationally. This paper presents the protocol for a study to evaluate the effectiveness (objective 1) and cost-effectiveness (objective 2) of using chlorhexidine in meatal cleaning prior to catheter insertion, in reducing catheter-associated asymptomatic bacteriuria and CAUTI.Methods and analysisA stepped wedge randomised controlled trial will be undertaken in three large Australian hospitals over a 32-week period. The intervention in this study is the use of chlorhexidine (0.1%) solution for meatal cleaning prior to catheter insertion. During the first 8 weeks of the study, no hospital will receive the intervention. After 8 weeks, one hospital will cross over to the intervention with the other two participating hospitals crossing over to the intervention at 8-week intervals respectively based on randomisation. All sites complete the trial at the same time in 2018. The primary outcomes for objective 1 (effectiveness) are the number of cases of CAUTI and catheter-associated asymptomatic bacteriuria per 100 catheter days will be analysed separately using Poisson regression. The primary outcome for objective 2 (cost-effectiveness) is the changes in costs relative to health benefits (incremental cost-effectiveness ratio) from adoption of the intervention.DisseminationResults will be disseminated via peer-reviewed journals and presentations at relevant conferences.A dissemination plan it being developed. Results will be published in the peer review literature, presented at relevant conferences and communicated via professional networks.EthicsEthics approval has been obtained.Trial registration number12617000373370, approved 13/03/2017. Protocol version 1.1.

Project description:Background and objectiveCatheter-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.MethodsAn 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 limitationsOut 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 implicationsCAUTI 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 summaryIn 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.

Project description:BackgroundReducing the need for antibiotics is crucial in addressing the global threat of antimicrobial resistance. Catheter-associated urinary tract infection (CAUTI) is one of the most frequent device-related infections that may be amenable to prevention. Interventions implemented nationally in England target behaviours related to catheter insertion, maintenance and removal, but the extent to which they target barriers to and facilitators of these behaviours is unclear. This strategic behavioural analysis applied behavioural science frameworks to (i) identify barriers to and facilitators of behaviours that lead to CAUTI (CAUTI-related behaviours) in primary, community and secondary care and nursing homes; (ii) describe the content of nationally adopted interventions; and (iii) assess the extent to which intervention content is theoretically congruent with barriers and facilitators.MethodsA mixed-methods, three-phased study: (1) systematic review of 25 studies to identify (i) behaviours relevant to CAUTI and (ii) barriers to and facilitators of CAUTI-related behaviours, classified using the COM-B model and Theoretical Domains Framework (TDF); (2) content analysis of nationally adopted CAUTI interventions in England identified through stakeholder consultation, classified using the Behaviour Change Wheel (BCW) and Behaviour Change Techniques Taxonomy (BCTTv1); and (3) findings from 1 and 2 were linked using matrices linking COM-B and TDF to BCW/BCTTv1 in order to signpost to intervention design and refinement.ResultsThe most frequently reported barriers to and facilitators of CAUTI-related behaviours related to 'environmental context and resources'; 'knowledge'; 'beliefs about consequences'; 'social influences'; 'memory, attention and decision processes'; and 'social professional role and identity.' Eleven interventions aiming to reduce CAUTI were identifed. Interventions were primarily guidelines and included on average 2.3 intervention functions (1-5) and six BCTs (2-11), most frequently 'education', 'training' and 'enablement.' The most frequently used BCT was 'information about health consequences' which was used in almost all interventions. Social professional role and identity and environmental context and resources were targeted least frequently with potentially relevant BCTs.ConclusionsInterventions incorporated half the potentially relevant content to target identifed barriers to and facilitators of CAUTI-related behaviours. There were missed opportunities for intervention as most focus on shaping knowledge rather than addressing motivational, social and environmental influences. This study suggests that targeting motivational, social and environmental influences may lead to more effective intervention design and refinement.
