Epidemiology, Microbiology and Outcomes of Catheter-Associated Urinary Tract Infection and Complicated Urinary Tract Infection in the USA

Real world utilization of nurse-driven urinary catheter removal protocol in patients with epidural pain catheters

BACKGROUND

Surgeons use indwelling bladder catheters (IBCs) to avoid urinary retention in patients with epidural analgesic catheters. Reduction of IBC-days is associated with improved catheter-associated urinary tract infection rates (CAUTI). This study investigates real world application of a Nurse-Driven Catheter Removal Protocol (NDCRP) to reduce IBC-days in this patient population.

METHODS

Patients with epidural catheters and IBC were targeted for IBC removal on post-operative day 1 (POD1). Patients were followed for application of the NDCRP, catheterization need, IBC re-anchoring, and complications.

RESULTS

One hundred and thirty-three patients had IBCs removed on POD1 (Protocol Group) and 50 patients did not (Non-Protocol Group). There was a reduction in IBC-days in the Protocol Group despite incomplete adherence to the NDCRP (1.55 days vs 4.64 days; P < .001). Ninety-three patients (70%) were able to spontaneously void after early IBC removal. Fourteen patients (11%) were able to spontaneously void after serial in-and-out catheterization (I/O). No significant difference in re-anchoring was found between the protocol and non-protocol groups (26 vs 4 patients; P = .09).

CONCLUSIONS

Early removal of IBCs (POD1) in patients with epidural catheters with the assistance of an NDCRP is a safe and successful strategy to reduce IBC-days in the hospital.

Antibacterial data synthesis challenges: a systematic review of treatments for complicated gram-negative urinary tract infections

Aim: To determine the suitability of network meta-analysis (NMA) using antibacterial treatment evidence in complicated urinary tract infection. Materials & methods: We conducted a systematic literature review to identify published clinical trial data for complicated urinary tract infection treatments. We performed a feasibility assessment to determine whether the available evidence would support the creation of a robust NMA, considering key assumptions of homogeneity, similarity and consistency. Results: Twenty-five trials met eligibility criteria. Risk of bias was low, and individual studies met their primary end point(s). Assumptions central to the conduct of a robust NMA were not met. Heterogeneity was ubiquitous, including baseline pathogen, treatment and patient characteristics. Conclusion: Limited and heterogeneous data identified make the use of NMA to compare novel antibacterial agents impractical and likely unreliable.

Patient and Family Engagement in Catheter-Associated Urinary Tract Infection (CAUTI) Prevention: A Systematic Review

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) are detrimental to health and are largely preventable with adherence to CAUTI prevention guidelines. Patient and family engagement in CAUTI prevention is often encouraged in these guidelines; however, little is known about how this engagement is operationalized in practice. A systematic review was conducted to synthesize the content, format, and outcomes of interventions that engage patients and/or families in CAUTI prevention.

METHODS

Two reviewers independently screened records from four databases up to March 2021 and searched reference lists of final articles. Included articles were primary research, tested an intervention, involved indwelling urinary catheters, and described at least one patient and/or family engagement method. Articles were appraised for quality using the Downs and Black checklist.

RESULTS

After 720 records were screened, 12 were included. Study quality ranged from good to poor, scoring lowest in internal validity. The most common formats of patient/family engagement were flyers/handouts (83.3%) and verbal education (58.3%). Common content areas were urinary catheter care and maintenance strategies. Most study outcomes (83.3%) measured CAUTI rates, and half measured patient/family-related outcomes. Improvements were seen in at least one outcome across all studies, but less than half (41.7%) showed statistically significant results.

CONCLUSION

The researchers found that most interventions lacked sufficient detail on the content, delivery, and/or outcome measurement of patient/family engagement, which limits transferability. More high-quality, generalizable trials are warranted in this area. Future research should focus on integrating publicly available resources into practice that can be tested for comprehension and revised based on feedback from target audiences.

Examining instruments used to measure knowledge of catheter-associated urinary tract infection prevention in health care workers: A systematic review

BACKGROUND

Catheter-associated urinary tract infection (CAUTI) is the most frequently occurring health care-associated infection among hospitalized patients. Adequate knowledge of CAUTI in health care workers supports effective prevention and control of the infection. This systematic review assesses instruments used to assess knowledge of CAUTI prevention in health care workers to inform future research. The catheter lifecycle model was used to evaluate the conceptual framework upon which the measurement instruments were based. Finally, the psychometric quality of these instruments was evaluated.

METHODS

Five electronic databases were searched for published studies and instruments. The COnsensus-based Standards for the selection of health status Measurement INstruments checklist was used to assess the psychometric quality reporting of the instruments.

RESULTS

Fifteen studies met the review inclusion criteria and 13 instruments were available for review. Most of the instruments did not address all knowledge components essential for CAUTI prevention as defined by the catheter lifecycle model. The psychometric quality of the instruments was not sufficiently evaluated.

CONCLUSIONS

Few instruments are available for CAUTI prevention knowledge measurement. The instruments were not closely aligned with the catheter lifecycle model as a framework. If CAUTI knowledge cannot be measured accurately using an effective instrument, this has the potential to impact negatively on clinical care and the focus of interventions. There is a need for a standardized instrument for the evaluation of CAUTI prevention knowledge so that targeted interventions can address knowledge deficits.
