  • Background: Immunocompromised children (ICC) with long-term central venous catheters or ports (CVCP) are at increased risk for bloodstream infections (BSI). National guidelines recommend CVCP removal when BSI are caused by certain pathogens, however compliance is unknown.

    Methods: Retrospective cohort analysis of ICC (age ≤ 21 years) with CVCP hospitalized from 1/2009-12/2015 with BSI due to Staphylococcus aureus, Pseudomonas spp., Enterococcus spp. or Candida spp. Relapse and recurrence were defined as isolation of the same pathogen from CVCP blood cultures at <14d and 14-60d, respectively from the date of the initial BSI. Demographic, clinical, laboratory, and outcome data were recorded.

    Results: Fifty-three children (median age 6.2 y, range 0.5-21 y) had 108 BSI episodes requiring 84 hospitalizations. Underlying medical conditions included malignancy (n=18, 34%), bone marrow (n=16, 30%) or solid organ transplant (n=4, 8%) recipients, and need for therapies via CVCP (n=15 (28%): biologics, hemodialysis or parenteral nutrition). Results are summarized in Table 1. All patients received appropriate antimicrobial therapy for a median of 14d [range 11-17d]. Antibiotic lock therapy was administered in 12 (19%) and ethanol lock in 4 (6%) episodes of retained CVCP.

    Conclusion: Despite national guidelines, the majority of CVCP were retained in our cohort of ICC. A 1.5-fold increase in complication rates was observed in patients with retained CVCP, with no mortality observed in those with CVCP removal. This data supports the need for CVCP removal, particularly in ICC with BSI from Candida spp. and Pseudomonas spp.
