A catheter-associated urinary tract infection (CAUTI) is one of the most common infections connected to medical devices — and per the CDC, it’s both preventable and treatable. Good day-to-day catheter care at home is most of what prevents it.
The single biggest risk factor
Per the CDC, prolonged catheter use is the most important risk factor for developing a CAUTI. This is why an ongoing catheter shouldn’t be treated as a permanent fixture without periodic review — it’s worth asking a healthcare provider directly whether it’s still needed, rather than assuming it stays in indefinitely by default.
What good catheter care actually looks like
| Do | Don’t |
|---|---|
| Wash hands before and after touching the catheter | Tug or pull on the tubing |
| Keep the urine bag positioned below the level of the bladder at all times | Twist or kink the catheter tubing |
| Ask periodically whether the catheter is still medically necessary | Assume routine hygiene isn’t necessary because the catheter “handles it” |
That bag position rule matters more than it sounds like it should — a bag positioned above bladder level can allow urine (and the bacteria in it) to flow backward toward the bladder, which is exactly the mechanism that causes many of these infections.
Signs of infection that need medical attention
- Burning or pain below the stomach
- Fever
- Burning sensation associated with urination
- Urinating more frequently than usual (in someone without a catheter) or unusual changes in output for someone catheterized
Most CAUTIs are treated with antibiotics, removing or changing the catheter, or both — a healthcare provider determines the right approach, but the earlier a change is reported, the more straightforward treatment tends to be.
Types of catheters, briefly
- Indwelling catheter — a tube left in place through the urethra, connected to a closed collection system. The most common type for ongoing home use.
- Intermittent (“in-and-out”) catheterization — inserted briefly to drain urine, then removed, repeated as needed.
- External catheter — a device (commonly a soft external sheath) that doesn’t enter the body, generally lower infection risk than indwelling catheters.
- Suprapubic catheter — surgically placed through the lower abdomen rather than the urethra.
Why this is a nursing task, not a general aide task
Catheter care — assessment, maintenance, recognizing early signs of a developing problem — is a skilled nursing function. A home health aide can assist with related daily tasks, but ongoing catheter management and monitoring calls for an RN or LPN involved in the care plan.
Our skilled nursing team provides catheter care and monitoring for clients across Brooklyn and Queens, including through private duty nursing for more continuous needs. Call (718) 232-2777 or use our contact page if you’re arranging care for someone with an ongoing catheter.
Frequently asked questions
What is the biggest risk factor for a catheter-associated infection?
Prolonged catheter use. It’s worth periodically confirming with a healthcare provider whether the catheter is still needed rather than assuming it stays in place indefinitely.
Where should the catheter bag be positioned?
Below the level of the bladder at all times. A bag positioned higher can allow urine to flow backward, which raises infection risk.
What are the signs of a catheter-related infection?
Burning or pain below the stomach, fever, burning during urination, and unusual changes in urinary frequency or output. These need medical attention.
Can a home health aide manage catheter care?
Ongoing catheter assessment and management is a skilled nursing task, requiring an RN or LPN — not something a home health aide is trained or licensed to handle independently.
How are catheter infections treated?
Typically with antibiotics, removal or replacement of the catheter, or both, as determined by a healthcare provider.
