Background
Microbiology
- May differ between oncology and non-oncology patients[1]
- In that study, the most common causes were coagulase-negative staphylococci, Staphylococcus aureus, Enterobacterales, and enterococci
- Others common causes include Pseudomonas aeruginosa and Candida species
- Far less common causes included streptococci and Stenotrophomonas
Definition
Infection Control
- For surveillance purposes, a CLABSI is essentially a bloodstream infection attributed to a catheter that was in place within 48 hours of blood culture
IDSA
- Catheter-related bloodstream infection (CRBSI) is defined by the IDSA
- Confirmed
- Peripheral culture and catheter tip culture both positive for same organism
- Peripheral culture and catheter lumen culture both positive for same organism with either
- Quantitative cultures showing ≥3-fold higher CFU from the catheter
- Time-to-positivity of the catheter culture 2 hours earlier than that of the the peripheral
- Possible
- Quantitative cultures from two different lumens of the same catheter positive for the same organism with ≥3-fold difference in CFU between lumens
Management
Short-term CVC or arterial line infection
- Uncomplicated: no other foci of infection, fever resolves promptly ≤72h, no other intravascular hardware, no evidence of endocarditis or suppurative thrombophlebitis, and (if S. aureus) no active malignancy or immunosuppression
- Coagulase-negative staphylococci: remove catheter and treat with antibiotic for 5-7 days; if catheter not removed, do lock therapy and treat for 10-14 days
- Staphylococcus aureus: remove catheter and treat with antibiotic for ≥14 days
- Enterococcus: remove catheter and treat with antibiotic for 7-14 days
- Gram-negative bacillus: remove catheter and treat with antibiotic for 7-14 days
- Candida: remove catheter and treat with antifungal for 14 days from first negative blood culture
- Complicated: anyone not meeting above definition of uncomplicated
- Remove catheter and treat with antimicrobial for 4-6 weeks, or for 6-8 weeks if osteomyelitis
Long-term CVC or port infection
- Definitions of complicated and uncomplicated are same as above
- Uncomplicated
- Coagulase-negative staphylococci: may retain and treat with lock therapy and antibiotic for 10-14 days; remove catheter if clinical deterioration or relapse
- Staphylococcus aureus: remove catheter and treat with antibiotic for 4-6 weeks (some exceptions apply)
- Enterococcus: may retain and treat with lock therapy and antibiotic for 7-14 days; remove catheter if clinical deterioration or relapse
- Gram-negative bacillus: remove catheter and treat with antibiotic for 7-14 days; if attempting salvage, treat with lock therapy and antibiotic for 10-14 days and reassess
- Candida: remove catheter and treat with antifungal for 14 days from first negative blood culture
Prevention
- Perform hand hygiene, use aseptic technique when manipulating catheter, use barrier precaution for insertion
- Remove catheters as soon as they are no longer needed
- Antimicrobial-impregnated catheters may be helpful
