The ABBA project (Assess Better Before Access): A retrospective cohort study of neonatal intravascular device outcomes.

Background: Venous access devices (VADs) play a vital role within the neonatal intensive care unit. However, there are significant risks associated with the use of VADs, with complications such as infection, thrombosis, device occlusion, and infiltration/extravasation frequently contributing to device-related failures and increasing the risk of significant patient harm or injury. This study aimed to explore the relationships between risk factors and different venous access device complications in the neonatal setting, and then use that evidence to develop an algorithm based on observational data.
