Objective: Identify risk factors for central line-associated bloodstream infections (CLABSI) in pediatric intensive care settings in an era with high focus on prevention measures.
Design: Matched, case-control study.
Setting: Quaternary children's hospital.
Patients: Cases had a CLABSI during an intensive care unit (ICU) stay between January 1, 2015 and December 31, 2020. Controls were matched 4:1 by ICU and admission date and did not develop a CLABSI.
Methods: Multivariable, mixed-effects logistic regression.
Results: 129 cases were matched to 516 controls. Central venous catheter (CVC) maintenance bundle compliance was >70%. Independent CLABSI risk factors included administration of continuous non-opioid sedative (adjusted odds ratio (aOR) 2.96, 95% CI [1.16, 7.52], = 0.023), number of days with one or more CVC in place (aOR 1.42 per 10 days [1.16, 1.74], = 0.001), and the combination of a chronic CVC with administration of parenteral nutrition (aOR 4.82 [1.38, 16.9], = 0.014). Variables independently associated with lower odds of CLABSI included CVC location in an upper extremity (aOR 0.16 [0.05, 0.55], = 0.004); non-tunneled CVC (aOR 0.17 [0.04, 0.63], = 0.008); presence of an endotracheal tube (aOR 0.21 [0.08, 0.6], = 0.004), Foley catheter (aOR 0.3 [0.13, 0.68], = 0.004); transport to radiology (aOR 0.31 [0.1, 0.94], = 0.039); continuous neuromuscular blockade (aOR 0.29 [0.1, 0.86], = 0.025); and administration of histamine H2 blocking medications (aOR 0.17 [0.06, 0.48], = 0.001).
Conclusions: Pediatric intensive care patients with chronic CVCs receiving parenteral nutrition, those on non-opioid sedative infusions, and those with more central line days are at increased risk for CLABSI despite current prevention measures.
