Catheter-associated urinary tract infections

Catheter-associated urinary tract infections (also called CAUTIs) happen when a tube called a catheter, used to drain urine from the bladder, gets infected. They are often used in hospitals before or after surgery and in people who have trouble with bladder control.

The symptoms of a catheter-associated UTI are like those of a regular urinary infection:

• Pain or burning when peeing.
• Cloudy, foul-smelling, or bloody urine.
• Blood in your urine.
• Fever or chills.
• Feeling the need to pee often or urgently.
• Lower belly pain or discomfort.
• Feeling tired or weak.
• Urine leaking around your catheter.

Older adults might not have the usual symptoms of an infection. Instead, they may feel confused or suddenly seem different mentally. If this happens to you or someone you care about, it’s important to see a doctor right away.

You will only be given a urinary catheter if your doctor believes it is necessary and it will be taken out as soon as possible. 

There are a few things you can do to lower the chances of a catheter-associated UTI coming back:

• Keep the drainage bag lower than your bladder.
• Empty the drainage bag multiple times a day.
• Make sure the catheter tube isn’t bent or blocked.
• Change the catheter at least once a month.
