Catheter Care Training for Care Staff: What Good Practice Looks Like

Catheter care is one of the most common clinical tasks care staff support, and one of the easiest places for infection risk to creep in unnoticed. A resident with a long-term catheter depends on staff getting the basics right every single day - hand hygiene, a closed drainage system, correct bag positioning, and prompt reporting of anything that looks wrong.

This guide sets out what good catheter care looks like in a care home or domiciliary setting, why catheter-associated urinary tract infection (CAUTI) is such a persistent risk, and where the line sits between catheter care (which most care staff can safely support) and catheter changing (a nurse-delegated clinical task). For a wider grounding in the principles behind all of this, see Learnsignal's CPD training courses for care staff.

What Is a Urinary Catheter and Why Is It Used?

A urinary catheter is a thin, flexible tube inserted into the bladder to drain urine when a person cannot empty their bladder normally. The most common type in care settings is an indwelling (Foley) catheter, held in place by a small balloon inflated inside the bladder and connected to a drainage bag via closed tubing. Catheters are used for a range of clinical reasons: urinary retention, certain neurological conditions, skin protection at the end of life, or short-term use after surgery or injury. They are a clinical intervention, not a convenience, and current guidance is consistently clear that a catheter should only be in place while there is a genuine clinical need, with regular review of whether it can be removed.

CAUTI: The Infection Risk Every Care Worker Needs to Understand

Catheter-associated urinary tract infection is widely recognised as one of the most common healthcare-associated infections, and the majority of urinary tract infections acquired in care settings are linked directly to catheter use (US Centers for Disease Control and Prevention, 2024). The risk is cumulative: every day a catheter remains in place adds to the chance that bacteria will travel along the tube into the bladder, which is why UK infection prevention guidance (NICE) places such heavy emphasis on only catheterising when necessary, reviewing the ongoing need regularly, and maintaining meticulous care of the catheter and drainage system while it remains in place (NICE, Healthcare-associated infections: prevention and control in primary and community care, CG139).

For care staff, the practical takeaway is simple: a catheter is not a "fit and forget" device. Every contact with it - emptying the bag, repositioning a resident, assisting with personal care - is a moment where poor technique can introduce infection, and every shift is an opportunity to reduce that risk through consistent, correct practice. This sits alongside the wider infection control principles covered in Learnsignal's infection prevention and control training for healthcare staff.

What Good Catheter Care Looks Like

NICE and Royal College of Nursing (RCN) guidance converge on a consistent set of practical standards. These are the elements every care worker supporting catheter care should be trained in and checked against.

Hand Hygiene and Personal Care

Hands must be decontaminated and a new pair of clean, non-sterile gloves worn before any contact with the catheter or drainage system, with hands washed again afterwards. Daily meatal hygiene - washing the area where the catheter enters the body with plain soap and water, not antiseptic solutions - is recommended, with attention to correct technique (front to back for women; retracting the foreskin fully for uncircumcised men before cleaning and returning it afterwards).

Keeping the Closed Drainage System Intact

The catheter should remain connected to a sterile, closed drainage system at all times. Breaking that connection unnecessarily - disconnecting tubing, opening the system to "check" something - is one of the single biggest infection risks, because it gives bacteria a direct route into the bladder. Any disconnection should only happen for a clear clinical reason, following the manufacturer's and provider's protocol.

Secure Fixation

The catheter should be secured to the resident's leg or abdomen with an appropriate securement device to stop it being pulled or tugged during movement. Unsecured catheters increase the risk of urethral trauma and can dislodge the retention balloon, causing pain, bleeding, or bypassing.

Bag Positioning and Emptying

The drainage bag must always be positioned below the level of the bladder - never lifted above it during transfers or repositioning - and must never rest on the floor. Positioning below the bladder relies on gravity to keep urine flowing away from the bladder rather than back towards it. Bags should be emptied regularly enough to keep urine flowing freely and to stop the bag becoming overfull, using a clean, non-touch technique for the outlet valve and a separate, clean container for each resident.

Recognising and Escalating Signs of Infection or Blockage

Care staff are often the first to notice something has changed, which makes recognition and prompt escalation one of the most valuable parts of catheter care training. Signs that should always be reported to a nurse or supervisor without delay include:

• Cloudy, dark, foul-smelling, or blood-stained urine
• No urine draining into the bag, or a sudden significant drop in output despite adequate fluid intake
• Leaking or urine bypassing around the catheter itself
• Pain or tenderness in the lower abdomen, back, or around the catheter site
• Fever, shivering, or feeling generally unwell
• In older residents, new or worsening confusion can be an early sign of infection and should never be dismissed as "just their age" - NICE guidance specifically flags acute confusion as a possible UTI indicator in older people

None of these signs need a care worker to diagnose the cause - that is a clinical judgement for a nurse. What matters is that staff recognise the sign, report it promptly, and document it accurately, because early escalation is what prevents a treatable infection turning into sepsis. Staff should be confident in both directions: recognising the red flags here, and recognising when a resident's deterioration may be sepsis, covered in Learnsignal's sepsis recognition and management training for care staff.

Who Should - and Should Not - Change a Catheter

This is one of the most important boundaries in catheter care, and one that training must make explicit. Catheter care - hygiene, checking the system, emptying and monitoring the bag, reporting problems - can be carried out by trained care staff as part of their normal duties. Catheter insertion or changing is a different matter entirely: it is a clinical procedure that should only be carried out by a registered nurse or other professional who has been assessed as competent to do it, or delegated to a suitably trained member of staff under clear supervision, in line with the Nursing and Midwifery Council's delegation principles (RCN, Catheter Care guidance).

Complex problems - a blocked catheter, a catheter that keeps bypassing, or one that has come out - should never be treated as routine care tasks for untrained staff. RCN guidance is explicit that assessing the underlying cause of a blocked or bypassing catheter requires clinical knowledge and skill, which makes it inappropriate to delegate to a healthcare assistant without that training. The safe default for care staff is: report, don't attempt.

Why This Matters for CQC Compliance

For registered providers in England, catheter care sits squarely under CQC Regulation 12 (Safe care and treatment), which requires providers to assess and manage clinical risks, prevent and control the spread of infection, ensure equipment is used safely, and make sure staff have the competence and training to carry out the tasks they are asked to do. A care home where staff are unclear on closed-system technique, bag positioning, or when to escalate is a clear Regulation 12 risk - and it is exactly the kind of practical, observable detail inspectors look for during a visit. Robust documentation of catheter care and any concerns raised also links directly to wider good governance expectations for providers.

Because catheter care intersects with skin integrity, hydration, and infection control more broadly, it is worth training staff on these areas together rather than in isolation - for example alongside guidance on pressure ulcer prevention in care homes, since immobility, moisture, and infection risk are closely linked for many of the same residents.

Building Catheter Care Into Your Training Programme

Good catheter care training should be practical and competency-based, not a one-off slide deck. It should cover the underlying "why" (infection risk, dignity, comfort), the observable "how" (hygiene technique, closed system, bag position, emptying), and a clear, memorable escalation pathway for anything abnormal. Refresher training matters as much as initial training - technique drifts over time, and new staff need to be checked against the same standard as experienced colleagues, not assumed to know it. Providers should be able to show, not just tell, that every member of staff supporting catheter care has been assessed as competent, and that the boundary between catheter care and catheter changing is understood by everyone on the rota.

Frequently Asked Questions

Can care assistants empty and check a catheter bag without nurse supervision?

In most care settings, yes - emptying and checking a catheter bag is considered catheter care rather than a clinical procedure, provided the care assistant has been trained and assessed as competent by their employer. What they should not do without appropriate clinical training and delegation is change the catheter itself, or attempt to resolve a blockage or bypassing catheter.

How often should a catheter drainage bag be emptied?

There is no single fixed interval that applies to every resident - it depends on fluid intake and bag capacity - but the guiding principle from NICE and RCN guidance is to empty frequently enough to maintain steady urine flow and prevent the bag becoming overfull, using a clean technique each time.

What is the single most important thing to get right in day-to-day catheter care?

Keeping the closed drainage system intact is generally regarded as the most critical factor, since breaking that closed connection unnecessarily is one of the clearest routes for infection to enter the bladder. Correct hand hygiene before and after any contact with the system runs a close second.

Is confusion in an older resident ever linked to a catheter problem?

Yes - new or worsening confusion in an older person can be an early sign of a urinary tract infection, including a catheter-associated one, and NICE guidance specifically highlights this. It should always be reported and never assumed to be unrelated or simply age-related without clinical assessment.

Catheter care is a small set of daily actions with a large safety margin - get them right consistently, and CAUTI risk drops significantly; get them wrong even occasionally, and a resident can end up in hospital with a preventable infection. Structured, competency-based training is what turns "we've told staff about this" into practice that actually protects residents and stands up to CQC scrutiny.
