Central Line-Associated Bloodstream Infection Management

Central Line-Associated Bloodstream Infection Management: Suspected CLABSI → Blood Cultures → Empiric Antibiotics → Remove Central Line? → LINE REMOVAL ...

Pathway Overview

14 steps

Algorithm Steps

14 total

  1. 01Start

    Suspected CLABSI

    Bacteremia + central line with no other source

  2. 02Action

    Blood Cultures

    Paired peripheral and catheter cultures

    • At least 2 sets from different sites
    • One from catheter hub, one peripheral
    • Differential time to positivity may help diagnosis
  3. 03Action

    Empiric Antibiotics

    Cover gram-positive, consider gram-negative

    • Vancomycin 15-20mg/kg IV q8-12h
    • ADD Gram-negative coverage if: Severe sepsis, immunocompromised, femoral line
    • Piperacillin-tazobactam or Cefepime
  4. 04Decision

    Remove Central Line?

    Preferred for most CLABSI

  5. 05Action

    LINE REMOVAL Recommended

    For most situations

    • S. aureus: Always remove
    • Candida: Always remove
    • P. aeruginosa: Always remove
    • Tunnel infection/port abscess: Remove
    • Septic shock/endocarditis: Remove
  6. 06Decision

    Organism Identification

  7. 07Action

    S. aureus

    High risk for complications

    • Remove line (mandatory)
    • TEE for endocarditis
    • Duration: 4-6 weeks if complicated, 2 weeks if uncomplicated
    • MSSA: Nafcillin; MRSA: Vancomycin/Daptomycin
  8. 08Action

    Echocardiogram

    TEE preferred for S. aureus

    • Recommended for all S. aureus CLABSI
    • Consider for persistent bacteremia
    • Assess for endocarditis
  9. 09Outcome

    Resolved

    Negative cultures, completed therapy

  10. 10Warning

    Complications

    Endocarditis, septic thrombosis, metastatic infection

  11. 11Action

    Coag-Negative Staph

    Most common pathogen

    • Can attempt salvage if uncomplicated
    • Duration: 5-7 days if line removed
    • 10-14 days if line retained + lock therapy
  12. Path rejoins step 09Shared downstream outcome
  13. 12Action

    Candida

    Fungemia

    • Remove line (mandatory)
    • Echinocandin: Caspofungin, Micafungin, or Anidulafungin
    • Duration: 14 days from first negative culture
    • Dilated eye exam for endophthalmitis
  14. Path rejoins step 09Shared downstream outcome
  15. 13Action

    Gram-Negative Rod

    P. aeruginosa high-risk

    • Pseudomonas: Remove line, 7-14 days
    • Enterobacteriaceae: 7-14 days
    • Targeted therapy based on susceptibilities
  16. Path rejoins step 09Shared downstream outcome
  17. 14Action

    Salvage (Keep Line)

    Limited situations only

    • CoNS without complications
    • No tunnel infection, no endocarditis
    • Line is critical/difficult to replace
    • Antibiotic lock therapy + systemic antibiotics
  18. Path rejoins step 06Shared downstream outcome
