Preventing catheter-associated urinary tract infections in hospital
Indwelling urinary catheters can be essential for patients with acute urinary retention, critical illness, complex surgery or precise fluid monitoring. They can also introduce bacteria into the urinary tract, particularly when left in place longer than clinically necessary. Catheter-associated urinary tract infection (CAUTI) is therefore a preventable hospital-acquired complication and a practical target for safer care.

Prevention begins before insertion. A clear indication, aseptic technique, suitable equipment and a daily review should work together as one process. In Australia, this approach aligns with antimicrobial stewardship and the safety principles promoted by the Australian Commission on Safety and Quality in Health Care.

Risk is shaped by the patient, the device and the environment. Older adults, people with diabetes, impaired immunity or urinary obstruction may be vulnerable, while breaks in the closed drainage system and poor hand hygiene increase exposure to pathogens. Hospitals in Sydney, Melbourne, Brisbane and regional centres also need systems that work across busy wards, emergency departments and transfers between facilities.
Patients and families can support prevention by understanding why a catheter is present and reporting pain, fever, new confusion, lower abdominal discomfort, cloudy urine or leakage. Clear explanations matter: cloudy or strong-smelling urine alone does not always indicate infection, and unnecessary urine cultures can lead to avoidable antibiotics.
| Approach | Main benefit | Important limitation |
|---|---|---|
| Intermittent catheterisation | Reduces continuous foreign-body exposure | Requires staff skill, timing and patient suitability |
| Indwelling urethral catheter | Provides reliable drainage for selected indications | Infection risk rises with duration |
| External urine collection device | Avoids urethral insertion in some patients | May be unsuitable with retention or skin problems |
| Suprapubic catheter | Can be useful for selected long-term needs | Requires a procedure and ongoing site care |
| Bladder ultrasound with a clinical plan | Helps assess retention without automatic catheterisation | Must be linked to appropriate escalation |
Use a catheter only for a clear indication
Appropriate indications include acute urinary retention, bladder outlet obstruction, selected urological procedures, prolonged immobilisation with a specific clinical need, and accurate urine output measurement in critically ill patients. A catheter should not be used simply because a patient is incontinent, staff need convenience, or a urine specimen is difficult to obtain.
Alternatives may include a urinal, commode, continence pad, timed toileting, bladder scanning or intermittent catheterisation. In Australian hospitals, local policies may differ between health services, but the principle is consistent: document the indication at insertion and define what must happen before removal.
A bladder scan can help distinguish retention from low urine production, although the result should be interpreted alongside symptoms, renal function and the wider clinical picture. For a patient transferred from an emergency department or another ward, the receiving team should confirm the indication rather than allowing the device to continue by default.
Insert the device using aseptic technique
Hand hygiene should occur immediately before and after catheter handling. Sterile equipment, sterile gloves for insertion, appropriate antiseptic preparation and a correctly sized catheter reduce the chance of introducing organisms. Staff should receive practical training and competency assessment, especially when caring for patients with difficult anatomy or previous urological surgery.
The smallest suitable catheter should be selected, with the balloon inflated only to the manufacturer’s recommended volume using sterile fluid. Force should never be used. If insertion is difficult, repeated attempts can cause urethral trauma and bleeding; early assistance from an experienced clinician or urology team is safer.
Patient dignity is part of safe technique. Explain the procedure, provide privacy and use positioning that minimises contamination. In a large metropolitan hospital or a small rural service, a standard insertion pack and an easily accessible protocol can reduce variation between clinicians and shifts.
Maintain a closed drainage system
After insertion, the catheter, tubing and drainage bag should remain a closed system. Unnecessary disconnections create opportunities for contamination. The bag should stay below bladder level, remain off the floor and be emptied using a clean container without allowing the outlet to touch the container or surrounding surfaces.
Tubing should be checked for kinks, compression and dependent loops that obstruct flow. Securement reduces traction and urethral movement, while routine personal hygiene with soap and water is generally sufficient. Antiseptic cleaning of the meatus, bladder irrigation and antibiotic bladder washes are not routine substitutes for good catheter care.
Staff should avoid manipulating the catheter to obtain a specimen. If a culture is clinically indicated, the sample should be collected from the designated sampling port using aseptic technique. Urine from the drainage bag is unsuitable for diagnosing a new infection because it may have been standing for an extended period.
Review the need every day
Duration is one of the strongest modifiable risk factors. A daily question—“Does this patient still need the catheter?”—should be visible during ward rounds, nursing handover and electronic documentation. Automatic stop orders or nurse-led removal protocols can help where governance arrangements permit them.
Removal should occur as soon as the indication ends, followed by a plan for monitoring voiding, bladder discomfort and retention. Some patients may need a post-void bladder scan, a timed toileting schedule or intermittent catheterisation. Re-catheterisation should be based on assessment rather than anxiety about a single high residual volume.
Electronic prompts can be useful, but they should support clinical judgement rather than create alert fatigue. A catheter dashboard may track insertion date, indication, ward and expected review date. In facilities using electronic medication and clinical records, integrating device review into routine workflows can make prevention more reliable.
Recognise infection without over-treating
CAUTI requires clinical assessment, not a positive urine culture alone. Bacteria in urine are common after catheterisation and may represent asymptomatic bacteriuria, which usually should not be treated with antibiotics. Fever, rigors, haemodynamic instability, flank pain or other compatible symptoms require prompt evaluation, including consideration of non-urinary sources.
New delirium or functional decline in an older person should trigger a broad assessment rather than an automatic diagnosis of UTI. A urine dipstick or culture can be misleading when used without symptoms. Unnecessary testing may expose patients to antibiotics, adverse effects and resistant organisms while diverting attention from the real cause of deterioration.
When infection is suspected, clinicians should assess the catheter’s age, drainage, obstruction and ongoing necessity. Replacing a long-standing catheter may be considered when clinically appropriate and according to local policy, particularly if a fresh specimen is required. Antibiotic selection should reflect local guidelines, allergies, renal function and culture results.
Build prevention into hospital culture
Successful programmes combine education, surveillance and feedback. Nurses, doctors, allied health professionals, assistants in nursing, patients and cleaners all influence catheter safety. Short bedside reminders, simulation training and audits of insertion technique can be more effective than a policy stored on an intranet page.
Measurement should include catheter days, device utilisation, documented indications, timely removal and confirmed infections. Results can be shared with ward teams in a constructive format. A service in Perth may face different staffing and transfer patterns from one in Canberra or regional Queensland, so improvement work should account for local workflow rather than copy a metropolitan model without adaptation.
Urological research also helps clinicians place catheter care within wider urinary tract practice. For example, reading about shock-wave stone treatment can clarify how stone disease and obstruction may affect drainage decisions, while broader evidence on metabolic syndrome and erectile function reinforces the importance of considering diabetes, vascular health and long-term urological wellbeing together.
Patient education should be practical and culturally safe. Explain how to keep the bag below the bladder, avoid pulling the tubing and request help before walking. Hospitals can provide translated information and interpreter support where needed. Online material should also be evaluated carefully: a general discussion of lemon water and acidity is not a substitute for advice about catheter symptoms or infection treatment, and home remedies should never delay clinical review.
Staff wellbeing supports reliable infection prevention. Busy shifts, interruptions and fatigue make small breaches more likely, so teams should design supplies and documentation around real working conditions. Even background choices in a staff space, such as using music for a calmer environment, should complement—not replace—adequate staffing, clear escalation pathways and respectful communication.
Hospitals can start with three actions: remove catheters without a current indication, standardise insertion and maintenance practice, and review every suspected infection for both clinical accuracy and prevention lessons. Patients should receive a clear plan at discharge if a catheter remains in place, including who will manage it, when it will be reviewed and which symptoms require urgent care.
Clinicians and hospital leaders can strengthen care by auditing catheter use this week, discussing results at the next ward meeting and aligning local procedures with Australian safety and antimicrobial stewardship guidance. Consistent daily decisions protect patients from avoidable infection while preserving catheterisation for the situations in which it genuinely improves care.
