Variations in indwelling urinary catheter use in four Australian acute care hospitals

AIMS AND OBJECTIVES

To identify the point prevalence of indwelling urinary catheters (IDCs) in adult inpatients in acute care hospitals, and to describe the indications for IDC insertion based on patient age, gender, specialty and hospital.

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) are preventable healthcare-associated infections. IDC duration is the strongest predictor of CAUTI, and little is known about characteristics of patients who receive an IDC.

DESIGN

Two single-day point prevalence surveys collected baseline patient data as part of a larger pre-post control-intervention study.

METHODS

Surveys were conducted at four acute care hospitals in NSW, Australia, for all adult patients. Data collection included IDC presence, insertion details and urine culture collection. Point prevalence data were linked with electronically extracted patient demographic data. This study is presented in line with STROBE checklist (See Supplementary File 1).

RESULT

Data from 1,630 patients were analysed, with 196 patients (12%) identified as having an IDC on the survey dates. IDC prevalence rates were higher in males (13%) than in females (11%). Critical care had the highest rate of patients with IDCs (42%). Urine cultures were collected in 70 patients with an IDC (43%).

CONCLUSIONS

Findings indicated similar rates of IDC use in males and females, and there was no significant difference in age between patients with or without an IDC. However, indication for IDC varied by patient age and gender. High rates of urine culture collection may represent routine collection.

RELEVANCE TO CLINICAL PRACTICE

IDC use is found across genders, all age groups and specialties. Nurses should be aware that any of their patients may have an IDC and be particularly aware of certain indications based on patient age and gender. Routine urine culture collection is not advised, and instead, nurses should be guided by clinical decision-making tools.

Avoiding inappropriate urinary catheter use and catheter-associated urinary tract infection (CAUTI): a pre-post control intervention study

Background

Urinary tract infection (UTI) as the most common healthcare-associated infection accounts for up to 36% of all healthcare-associated infections. Catheter-associated urinary tract infection (CAUTI) accounts for up to 80% of these. In many instances indwelling urinary catheter (IDC) insertions may be unjustified or inappropriate, creating potentially avoidable and significant patient distress, embarrassment, discomfort, pain and activity restrictions, together with substantial care burden, costs and hospitalisation. Multifaceted interventions combining best practice guidelines with staff engagement, education and monitoring have been shown to be more effective in bringing about practice change than those that focus on a single intervention. This study builds on a nurse-led initiative that identified that significant benefits could be achieved through a systematic approach to implementation of evidence-based practice.

Methods

The primary aim of the study is to reduce IDC usage rates by reducing inappropriate urinary catheterisation and duration of catheterisation. The study will employ a multiple pre-post control intervention design using a phased mixed method approach. A multifaceted intervention will be implemented and evaluated in four acute care hospitals in NSW, Australia. The study design is novel and strengthened by a phased approach across sites which allows for a built-in control mechanism and also reduces secular effects. Feedback of point prevalence data will be utilised to engage staff and improve compliance. Ward-based champions will help to steward the change and maintain focus.

Discussion

This study will improve patient safety through implementation and robust evaluation of clinical practice and practice change. It is anticipated that it will contribute to a significant improvement in patient experiences and health care outcomes. The provision of baseline data will provide a platform from which to ensure ongoing improvement and normalisation of best practice. This study will add to the evidence base through enhancing understanding of interventions to reduce CAUTI and provides a prototype for other studies focussed on reduction of hospital acquired harms. Study findings will inform undergraduate and continuing education for health professionals.
