From the Guidelines
For a urinary tract infection (UTI) in a patient with a chronic indwelling Foley catheter, I recommend empiric treatment with antibiotics and consideration of catheter replacement if it has been in place for more than 2 weeks, as this approach is supported by the most recent guidelines 1. When managing a UTI in a patient with a chronic indwelling Foley catheter, it is essential to consider the following key points:
- Only treat symptomatic UTIs, not asymptomatic bacteriuria, as the presence of symptoms such as fever, suprapubic pain, flank pain, altered mental status, or malaise indicates the need for antibiotic therapy.
- Before starting antibiotics, obtain a urine culture to guide treatment and consider changing the catheter if it has been in place for more than 2 weeks, as recommended by the Infectious Diseases Society of America 1.
- Empirical treatment decisions can be made based on review of the individual patient’s urinary tract anatomy or dysfunction, allergies medication list for interactions, microbiological and prior treatment history, the type of UTI (eg, cystitis vs pyelonephritis), and the clinical severity of presentation 1.
- Long-term prevention strategies include maintaining a closed drainage system, ensuring proper catheter care, considering intermittent catheterization instead of indwelling catheters when possible, and removing the catheter as soon as medically appropriate.
- The recommended duration of antimicrobial treatment for patients with CA-UTI who have prompt resolution of symptoms is 7 days, and 10–14 days of treatment is recommended for those with a delayed response, regardless of whether the patient remains catheterized or not 1. Some possible antibiotic regimens for the treatment of UTI in patients with a chronic indwelling Foley catheter include:
- Trimethoprim-sulfamethoxazole (TMP-SMX) 160/800 mg twice daily for 7 days
- Ciprofloxacin 500 mg twice daily for 7 days
- Nitrofurantoin 100 mg four times daily for 7 days It is crucial to note that the choice of antibiotic should be guided by the results of the urine culture and susceptibility testing, as well as the patient's medical history and potential allergies.
From the FDA Drug Label
Patients with a resistant pathogen, recurrent UTI, women over age 55 years, and with an indwelling catheter were initially excluded, prior to protocol amendment which took place after 30% of enrollment The FDA drug label does not answer the question.
From the Research
Treatment Options for UTI in Patients with Chronic Indwelling Foley Catheter
- The treatment of urinary tract infections (UTIs) in patients with a chronic indwelling Foley catheter should be tailored to the specific needs of the patient, taking into account the presence of the catheter and the potential for antibiotic resistance 2, 3.
- First-line empiric antibiotic therapy for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females is not directly applicable to patients with a chronic indwelling Foley catheter, as they are considered to have a complicated UTI 2.
- For patients with a chronic indwelling Foley catheter, treatment options may include:
- Fluoroquinolones, such as ciprofloxacin or levofloxacin, which have been shown to be effective in treating UTIs in patients with indwelling catheters 4, 5.
- Broad-spectrum penicillins, such as amoxicillin-clavulanate, in combination with a beta-lactamase inhibitor 6.
- Cephalosporins, such as cefepime or ceftazidime, which have a broad spectrum of activity against Gram-negative bacteria 2, 6.
- Aminoglycosides, such as gentamicin or tobramycin, which may be used in combination with other antibiotics 2, 6.
- It is essential to use the new antimicrobials wisely for treatment of UTIs caused by multidrug-resistant (MDR) organisms to avoid resistance development 2.
- Prevention of recurrent UTI in patients with a chronic indwelling Foley catheter is crucial, and may involve the use of prophylactic antibiotics, as well as measures to minimize the risk of catheter-associated UTIs, such as proper catheter management and hygiene 3.
