Severe Neutropenia at the Time of Implantable Subcutaneous Chest Port Insertion Is Not a Risk Factor for Port Removal at a Tertiary Pediatric Center

Abstract

Purpose To determine if severe neutropenia at the time of chest port insertion is a risk factor for port removal and central catheter–associated bloodstream infection (CCABSI) in pediatric patients. Materials and Methods From May 2007 to June 2015, 183 consecutive patients (mean age, 9.9 y; range, 0.75–21 y) had a port inserted at a single tertiary pediatric center. Seventy-two had severe neutropenia at the time of port insertion (absolute neutrophil count [ANC] range, 0–500/mm3; mean, 185/mm3). Follow-up until port removal or death and CCABSI events were recorded. Results Within the first 30 days, similar incidences of CCABSI (12.5% of patients with severe neutropenia [n = 9] vs 4.5% of patients without [n = 5]), port removal for infection (2.8% [n = 2] vs 2.7% [n = 3]), and local port infection (2.8% [n = 2] vs 0.9% [n = 1]) were observed in both groups (P >.05), but the rate of CCABSI per 1,000 catheter-days was higher for patients with severe neutropenia (P =.045). Overall, similar incidences of CCABSI (18.1% [n = 13] vs 16.2% [n = 18]), port removal for infection (2.8% [n = 2] vs 7.2% [n = 8]), local port infection (2.8% [n = 2] vs 2.7% [n = 3]), and CCABSIs per 1,000 catheter-days (0.332 vs 0.400) were observed in both groups (P >.05). Conclusions Port placement in patients with severe neutropenia can be performed without an increased incidence of port removal for infection. The majority of CCABSIs were successfully treated without port removal.
