Central venous access trends in children
Abstract:
Purpose: To evaluate central venous access placement trends for radiology and non-radiology services over the last decade.
Materials and methods: Children who had central venous access procedures included in a large administrative database of 49 pediatric institutions in the United States between 2010 and 2020 were included. Patient demographics and patient specific factors were compared between groups. The percentage of procedures performed by interventional radiology (IR) and non-radiology services were compared over time and by region.
Results: A total of 483,181 vascular access encounters were recorded (45.3% female; median age 2 years (IQR 0-11 years)). Approximately one quarter of vascular access encounters were IR-led, with a slight increase of 3.8% between 2010 and 2020. Children who underwent IR-placed vascular access were older (median age of 4 years compared to 1 year in non-radiology encounters). Interventional radiology-placed access was greatest in the Midwest (33.5%) with a decrease of 5.9% over the study period; in the other three regions, IR-performed encounters increased. Patient comorbidities more prevalent in the IR encounters were technology dependence (42.4% of all radiology encounters), gastrointestinal (34.9%), respiratory (20.8%), and transplant (8.1%), while those which were more prevalent in the non-radiology encounters were nephrology/urology (21.4% of all non-radiology encounters), prematurity/neonatal (17.3%), and malignancy (17.3%).
Conclusions: Interventional radiology-provided vascular access services have slightly increased over the last decade without significant service-line transfer to other specialties. Underlying comorbidities in IR-led vascular access encounters vary across institutions based on referral patterns, possibly reflecting the adoption of ultrasound guidance by other pediatric subspecialties.
