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

Objective: 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.

Methods: 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.

Results: 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%.

Conclusion: 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.
