A catheter-associated urinary tract infection (CAUTI) is one of the most common infections a person can contract in the hospital, according to the American Association of Critical-Care Nurses.
Indwelling catheters are the cause of this infection. An indwelling catheter is a tube inserted into your urethra. It drains urine from your bladder into a collection bag. You may need a catheter if you have had surgery or cannot control your bladder function, and there is a need to closely monitor how much urine your kidneys are producing.
A CAUTI has similar symptoms to a typical urinary tract infection (UTI). These include:
CAUTIs can be difficult to diagnose in if you are already hospitalized because similar symptoms may be part of your original illness. In elderly people, changes in mental status or confusion can be signs of a CAUTI.
If you have a catheter and notice any localized discomfort, tell your nurse or doctor right away.
Bacteria or fungi may enter your urinary tract via the catheter. There they can multiply, causing an infection.
There are a number of ways infection can occur during catheterization. For example:
Clean insertion and removal techniques can help lower the risk of a CAUTI. Daily catheter care is required as well. Catheters shouldn’t be left in longer than needed, as longer use is associated with a higher risk of infection.
A CAUTI is diagnosed using a urine test. Urinalysis can detect blood cells in your urine. Their presence may signal an infection.
Another useful test is a urine culture. This test identifies any bacteria or fungi in your urine. Knowing what caused the infection can help your doctor treat it.
Sometimes, your bladder doesn’t move urine out of your body quickly enough. This can happen even with a catheter. Retained urine is more likely to grow bacteria. Infection risk increases the longer urine stays in your bladder. Your doctor may recommend an imaging test of your bladder, such as an ultrasound scan, to see if you’re retaining urine.
Prompt treatment of a CAUTI is essential. An untreated UTI can lead to a more serious kidney infection. In addition, people with catheters may already have conditions that compromise their immune systems. Fighting off a CAUTI can cause further immune system stress. This makes you more vulnerable to future infections.
CAUTIs tend to be more resistant to treatment than other UTIs. This is true in general for hospital-acquired infections. CAUTIs are dangerous because they can lead to severe kidney infections. This makes prompt diagnosis and treatment vital for your long-term health.
Your doctor will likely prescribe antibiotics to kill off any harmful bacteria. In most cases, these will be oral antibiotics. You may be given antibiotics intravenously in the case of a severe infection. If the infection causes bladder spasms, your doctor may prescribe an anti-spasmodic to lessen bladder pain.
Increasing your fluid intake can also help you feel better by flushing bacteria from your urinary system. Certain fluids should be avoided. These include:
CAUTIs are one of the most common hospital-related infections. Therefore, many healthcare organizations place great emphasis on prevention.
Your doctor will carefully consider whether a catheter is necessary. They’ll also remove a necessary catheter as soon as possible.
In addition, you or the hospital staff should:
Frequent hand-washing and good hygiene practices on the part of hospital staff can also help prevent CAUTIs.
