Foley Catheter Management Guidelines

Insertion Technique

• The Centers for Disease Control and Prevention recommends using maximal sterile barrier precautions, including cap, mask, sterile gown, sterile gloves, and sterile full body drape during insertion 1, 2
• Prepare the insertion site with an appropriate antiseptic, such as 0.5% chlorhexidine preparation with alcohol, and allow it to dry completely according to manufacturer's recommendations before catheter insertion 2, 3

Catheter Selection and Maintenance

• Connect the catheter to a closed drainage system to minimize infection risk, as recommended by the Centers for Disease Control and Prevention 1, 2
• Position the drainage bag below bladder level but not touching the floor, to prevent backflow and minimize infection risk 4
• Do not disconnect the catheter from the drainage system unless absolutely necessary, to maintain a closed system and prevent infection 1

Dressing Management

• Use either sterile gauze or sterile, transparent, semi-permeable dressing to cover the catheter insertion site, and replace gauze dressings every 2 days 3, 4
• Replace transparent dressings at least every 7 days, or immediately if they become damp, loosened, or visibly soiled 3, 4

Catheter Replacement Schedule

• Do not replace catheters at routine, fixed intervals; instead, change the catheter based on clinical indications such as obstruction, infection, or visible biofilm formation 1, 2
• Change the catheter every 2-4 weeks, or as needed based on individual patient factors and catheter performance, as recommended by the Centers for Disease Control and Prevention 1, 2

Irrigation Recommendations

• Use aseptic technique when irrigating the catheter, and use a closed irrigation system when possible, to minimize infection risk 1
• Use sterile irrigation solution, and document the reason for irrigation, amount and type of solution used, and patient response 4

Infection Prevention

• Perform hand hygiene before and after handling the catheter or drainage system, to prevent the spread of infection 1, 4
• Maintain a closed drainage system at all times, and do not use topical antibiotic ointments at the insertion site, to minimize infection risk 1, 3, 4
• Regularly assess for signs of infection, such as fever, suprapubic pain, cloudy urine, or hematuria, and remove the catheter as soon as it is no longer needed 2, 4, 5

Common Pitfalls to Avoid

• Do not submerge the catheter or insertion site in water, and avoid routine catheter irrigation, which can introduce pathogens 1, 4
• Do not clamp the catheter unnecessarily, as this can lead to bladder distension and increased infection risk 6
• Avoid using force when inserting or removing catheters, to prevent urethral trauma and patient discomfort 4
