Permicath Infection Prevention and Management
Infection Risk Factors
- Permicath-related infections are primarily caused by migration of skin organisms at the insertion site into the cutaneous catheter tract with subsequent colonization of the catheter tip, which is the most common route of infection for permanently implanted catheters 2
- Contamination of the catheter hub contributes substantially to intraluminal colonization of long-term catheters 2
- The most common pathogens causing permicath infections include Gram-positive bacteria, such as coagulase-negative staphylococci, Staphylococcus aureus, and Enterococcus species, as well as Gram-negative microorganisms, which account for approximately 20% of infections 1
- Catheter material plays a significant role in infection risk, with catheters made of polyvinyl chloride or polyethylene being less resistant to microbial adherence compared to those made of Teflon, silicone elastomer, or polyurethane 3
Infection Prevention Strategies
- The American College of Surgeons and other medical societies recommend using maximal sterile barrier precautions during insertion, including cap, mask, sterile gloves, gown, and sterile full-body drape, to reduce infection risk 1
- Proper hand hygiene before catheter insertion and maintenance is crucial, as emphasized by the Centers for Disease Control and Prevention (CDC) 1
- The use of >0.5% chlorhexidine skin preparation with alcohol for antisepsis at the insertion site is recommended by the Infectious Diseases Society of America (IDSA) 4
- Selecting the optimal insertion site, such as the subclavian site, can reduce infection risk, as suggested by the Society of Interventional Radiology 3
- Implementing ultrasound guidance during insertion can reduce the number of catheter placement attempts and subsequent infection risk, as recommended by the American Institute of Ultrasound in Medicine (AIUM) 1
Ongoing Maintenance
- Educating and designating only trained healthcare personnel for catheter care can reduce infection risk, as emphasized by the Association for Professionals in Infection Control and Epidemiology (APIC) 1
- Using sutureless securement devices with needle-less connectors can minimize the risk of catheter-related infections, as recommended by the CDC 1
- Applying sterile, transparent dressings and changing them according to protocol can reduce bacterial colonization, as suggested by the World Health Organization (WHO) 1
- Using chlorhexidine-impregnated dressings at the exit site and exchanging them weekly can decrease bacterial colonization, as recommended by the Society for Healthcare Epidemiology of America (SHEA) 5
- Maintaining aseptic technique during all catheter manipulations is crucial, as emphasized by the CDC 6
Catheter Selection
- Choosing catheters with the minimum number of lumens necessary for patient management can reduce infection risk, as recommended by the IDSA 1
- Selecting catheters made of materials that resist microbial adherence, such as Teflon, silicone elastomer, or polyurethane, can reduce infection risk, as suggested by the Society of Interventional Radiology 3
- Considering antimicrobial-impregnated catheters for patients at high risk of infection can reduce infection risk, as recommended by the SHEA 5
Management of Permicath Infections
- For suspected catheter-related bloodstream infections (CRBSI), obtaining blood cultures from both the catheter and a peripheral vein is recommended by the IDSA 6
- If the patient has unexplained sepsis or erythema at the catheter site, the catheter should be removed as soon as possible, as emphasized by the CDC 6
- Complete device removal is the definitive management strategy whenever feasible, as colonization significantly increases the risk of clinical infection, as recommended by the SHEA 5
- For empiric therapy, selecting antimicrobials based on likely pathogens associated with the specific device, such as using vancomycin if MRSA risk is high, is recommended by the IDSA 5
Special Considerations
- Patients receiving chemotherapy, total parenteral nutrition, or who are neutropenic for a prolonged period are at increased risk for catheter-related infections, as noted by the American Cancer Society 1
- The average cost per episode of CRBSI is approximately $45,814, making prevention strategies highly cost-effective, as reported by the CDC 1
- Biofilm formation on catheters can make infections difficult to eradicate and confer inherent resistance to antibiotics, as noted by the National Institutes of Health (NIH) 6
- Femoral insertion sites should be avoided when possible due to higher infection rates and increased risk of deep venous thrombosis, as recommended by the Society of Interventional Radiology 3
