Abstract
Abstract
Background:
Central line-associated bloodstream infection (CLABSI) causes significant harm in neonatal intensive care unit (NICU) patients. However, data regarding risk factors and prevention strategies for CLABSI in NICU patients is limited.
Objective:
To examine risk factors for CLABSI in a NICU population, with particular interest in central line type and site placement.
Design:
Retrospective case–control study.
Setting:
NICU (Level IV, 67 bed) at a pediatric hospital in South Texas.
Participants:
All central line insertions and subsequent CLABSI cases were extracted from the EHR for NICU admissions occurring from January 1, 2018, to November 3, 2022 (N = 1,356), along with potential CLABSI risk factors.
Methods:
Central line insertions resulting in CLABSI (N = 35) were compared to instances without CLABSI (N = 1,321) using bivariate and multivariate analysis, with propensity score matching.
Results:
Multivariate risk factors include implantable device (odds ratio [OR] = 14.5, P < .001), neck site placement (OR = 7.2, P < .001), and device dwell time (OR = 5.6, P = .001), as well as years 2021 (OR = 5.1, P = .017) and 2022 (OR = 5.9, P = .011). This indicates the odds of contracting CLABSI are 14.5 times higher when an implantable central line is used compared to the reference category (PICC devices). When cases are paired with matched controls, likelihood of CLABSI is 7.1% higher in patients with an implantable device than in similar patients with other central lines (p = 0.034).
Conclusions:
Implantable central lines are an independent risk factor for CLABSI in NICU patients at this facility.
