Impact of an Evidence-Based Bundle on Catheter-Associated Sepsis Incidence in Neonatal Intensive Care: A Quality Improvement Project

Year: 2025

Type: article

Abstract: Background: Central line-associated bloodstream infections (CLABSIs) in neonatal intensive care units (NICUs) pose a significant risk, especially for very low birth weight infants due to their immature immune systems and the need for invasive procedures. The implementation of evidence-based bundles, as recommended by international guidelines, has proven effective in significantly reducing CLABSI rates, improving clinical outcomes, and lowering hospital costs. However, evidence from long-term, real-world quality-improvement programs in European NICUs—especially those using repeated PDSA cycles and detailed monitoring across multiple periods—remains limited. Methods: This quality improvement prospective study, conducted in the NICU of “V. Buzzi” Children’s Hospital, aimed to reduce high CLABSI rates using a plan-do-study-act (PDSA) framework. A multidisciplinary team developed and implemented a new evidence-based central line bundle in 2021, focusing on standardized practices, enhanced training, and monitoring. The study analyzed 594 CVCs placed in 348 neonates across a total 4-years period (P1–P12). Results: Implementation of a central line bundle significantly reduced CLABSI rates from 29.1 to 2.2 per 1000 CVC days (p-value 0.002), with notable variations during intermediate periods. Birth weight and study period progression were the only variables significantly associated with CLABSI reduction. Conclusions: Infection rates dropped significantly post-intervention, achieving zero in one of the latest periods: continuous monitoring, staff training, and targeted interventions were pivotal. Future efforts will focus on refining practices, increasing tunneled centrally inserted central catheter (CICC) use, and sustaining prevention measures.
