Immediate Catheter Management

The Infectious Diseases Society of America (IDSA) guidelines recommend removing the infected temporary catheter immediately for gram-negative bacilli, including Klebsiella, in short-term catheters 2, 3, 4
For hemodialysis patients, insert a temporary (non-tunneled) catheter at a different anatomical site, and do not exchange over a guidewire unless absolutely no alternative sites exist 1
The IDSA guidelines explicitly state that short-term catheters should be removed from patients with CRBSI due to gram-negative bacilli, S. aureus, enterococci, fungi, and mycobacteria 2, 3, 4

The IDSA guidelines recommend starting empirical therapy immediately with vancomycin plus gram-negative coverage while awaiting culture susceptibility results 1
The IDSA guidelines for hemodialysis CRBSI recommend vancomycin plus coverage for gram-negative bacilli based on local antibiogram (third-generation cephalosporin, carbapenem, or β-lactam/β-lactamase combination) 1

Treat for 10-14 days after catheter removal for uncomplicated CRBSI 1, 6
If bacteremia persists >72 hours after catheter removal despite appropriate antibiotics, extend therapy to 4-6 weeks 1, 6, 2
For complicated infections (endocarditis, suppurative thrombophlebitis, or osteomyelitis), treat for 4-6 weeks (or 6-8 weeks for osteomyelitis in adults) 1, 6, 2

Obtain repeat blood cultures 72 hours after initiating therapy to document clearance of bacteremia 1, 2, 3, 4
If blood cultures remain positive at 72 hours, this indicates treatment failure and necessitates extended therapy (4-6 weeks) and evaluation for metastatic infection 1, 2

If the patient develops severe sepsis, unexplained persistent fever, or hemodynamic instability, remove the catheter immediately regardless of other factors 8, 1
Patients should wear surgical masks during catheter removal procedures, and healthcare staff must use appropriate PPE 5
Monitor for post-removal site infection as a potential complication 5
