A Process Evaluation Approach to Central Line-Associated Bloodstream Infection Reduction in a Neonatal Population

To reduce the rate of central line-associated bloodstream infections (CLABSI) in the M Health Fairview Neonatal Intensive Care Unit (NICU) from 2.15 infections per 1,000 central line days to less than one per 1,000 line days using process evaluation.

An interdisciplinary team used process mapping and Failure Modes and Effects Analysis (FMEA) to identify root causes and improvement opportunities in central line maintenance. The focus was on neonates born at <32 weeks of gestational age and weighing less than 750 g. Interventions included standardized clean space, algorithms to reduce line access, and standardized kits for line maintenance.

Over 4 years, the project achieved an 86.6% reduction in CLABSI events, decreasing from 15 events in 2019 to two in 2023. The CLABSI rate dropped by 85%, from 2.15 to 0.32 per 1,000 line days. Statistical analysis indicated a significant reduction in FMEA risk scores for the identified failure modes, with an average reduction of 33%.

The process-focused approach and interdisciplinary collaboration significantly reduced CLABSI rates in the NICU. Future efforts should aim to maintain these improvements and achieve a target of zero CLABSI events.
