RESUMO
BACKGROUND AND AIMS: Central line-associated bloodstream infections (CLABSIs) are the main complication in children with home parenteral nutrition (HPN) and some patients develop recurrent CLABSIs (REC-CLABSIs), defined as two or more infections within six months. Our aims were to assess the incidence and to characterize the risk factors of REC-CLABSIs in children with HPN. METHODS: We characterized 79 HPN children from 2014 to 2019 and calculated the incidence of CLABSIs. To minimize the risk of bias related to the exposure time of the septic risk, we paired the patients according to their central venous catheter (CVC) dwell time. After analyzing the whole cohort, a univariate and multivariate unconditional logistic regression was performed on the paired cohort. RESULTS: We included 75 (94.9%) children with a mean age of 7.11 years. The rate of septicemia was 1.55/1000 CVC days, mainly with Staphyloccocus sp. The patients with recurrent CLABSIs (REC group) represented 25% of the cohort, with an incidence of 2.99/1000 CVC days. In the whole cohort, a higher risk of recurrent infections was significantly associated with a longer CVC dwell time (OR = 1.04, IC 95% [1.01-1.06], p = 0.004), and with care located in rehabilitation care facilities (RCF) compared to home (OR = 6, IC 95% [1.5-26.6], p = 0.012). When children were paired according to their CVC dwell time, only in univariate analysis did the care in RCF remain significant (OR = 6.27, IC 95% [1.21-32.5], p = 0.03). CONCLUSIONS: Recurrent CLABSIs incidence was 2.99/1000 CVC days. Our study suggests that preventive measures should be implemented especially in RCFs to reduce the proportion of children with recurrent infections. A multicenter study is needed to confirm our results in a larger cohort with several RCFs.
