Housestaff Knowledge Related to Urinary Catheter Use and Catheter-Associated Urinary Tract Infections

Urinary Tract Infections: 2021 Update

Catheter-associated urinary tract infection (CAUTI) remains one of the most prevalent, but preventable, health care-associated infections and predominantly occurs in patients with indwelling urinary catheters. Duration of urinary catheterization is the most important modifiable risk factor for development of CAUTI. Alternatives to indwelling catheters should be considered in appropriate patients. If indwelling catheterization is necessary, proper aseptic practices for catheter insertion and maintenance and use of a closed catheter collection system are essential for preventing CAUTI. The use of intervention bundles and collaboratives helps in the effective implementation of CAUTI prevention measures.

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.

Change in staff perspectives on indwelling urinary catheter use after implementation of an intervention bundle in seven Swiss acute care hospitals: results of a before/after survey study

OBJECTIVE

To evaluate changes in staff perspectives towards indwelling urinary catheter (IUC) use after implementation of a 1-year quality improvement project.

DESIGN

Repeated cross-sectional survey at baseline (October 2016) and 12-month follow-up (October 2017).

SETTING

Seven acute care hospitals in Switzerland.

PARTICIPANTS

The survey was targeted at all nursing and medical staff members working at the participating hospitals at the time of survey distribution. A total of 1579 staff members participated in the baseline survey (T₀) (49% response rate) and 1527 participated in the follow-up survey (T₁) (47% response rate).

INTERVENTION

A multimodal intervention bundle, consisting of an evidence-based indication list, daily re-evaluation of ongoing catheter need and staff training, was implemented over the course of 9 months.

MAIN OUTCOME MEASURES

Staff knowledge (15 items), perception of current practices and culture (scale 1-7), self-reported responsibilities (multiple-response question) and determinants of behaviour (scale 1-7) before and after implementation of the intervention bundle.

RESULTS

The mean number of correctly answered knowledge questions increased significantly between the two survey periods (T₀: 10.4, T₁: 11.0; p<0.001). Self-reported responsibilities with regard to IUC management by nurses and physicians changed only slightly over time. Perception of current practices and culture in regard to safe urinary catheter use increased significantly (T₀: 5.3, T₁: 5.5; p<0.001). Significant changes were also observed for determinants of behaviour (T₀: 5.3, T₁: 5.6; p<0.001).

CONCLUSION

We found small but significant changes in staff perceptions after implementation of an evidence-based intervention bundle. Efforts now need to be targeted at sustaining and reinforcing these changes, so that restrictive use of IUCs becomes an integral part of the hospital culture.

Urinary Tract Infections

Catheter-associated urinary tract infection (CAUTI) remains one of the most prevalent, yet preventable, health care-associated infections and predominantly occurs in patients with indwelling urinary catheters. Targeted strategies for prevention of CAUTI include limiting urinary catheter use; physician reminder systems, nurse-initiated discontinuation protocols, and automatic stop orders have successfully decreased catheter duration. Alternatives to indwelling catheters should be considered in appropriate patients. If indwelling catheterization is necessary, proper aseptic practices for catheter insertion and maintenance and closed catheter collection system is essential for preventing CAUTI. The use of "bladder bundles" and collaboratives aids in the effective implementation of CAUTI prevention measures.
