Background:
Access site complications are among the most common complications following peripheral vascular interventions. Previous studies have demonstrated a reduced rate of complications with ultrasound-guided vascular access (UGVA). The objective of this study is to evaluate the regional use of UGVA within the Vascular Quality Initiative (VQI).
Methods:
The VQI peripheral intervention module between 2010 and 2018 was evaluated. Regional ID was used to compare distribution of ultrasound usage. Regions were grouped into terciles based on the rate of ultrasound use. Patients were categorized based on type of access. Primary outcome was use of ultrasound across regions. Secondary outcomes were access site complications.
Results:
Over 43,000 cases across the 18 VQI regions were evaluated. The average rate of ultrasound usage was 71% across the regions with a wide variation (range 38-97%). There is a significant difference in utilization among the top third (87%), middle third (79%), and bottom third (58%) (P < 0.001). Average sheath size was similar across all 3 groups. A higher use of ultrasound-guided access was associated with significantly fewer access site complications (top third 1.96% vs. bottom third 3.04%, P < 0.001), the most significant of which was a decreased rate of access site hematoma (top third 1.37% vs. bottom third 2.35%, P < 0.001).
Conclusions:
This is the first study to evaluate ultrasound-guided access across VQI regions. Our results demonstrate that despite strong evidence supporting the utilization of UGVA, there remains a wide variation in ultrasound usage across VQI regions. This is also the first study to show that the prevalence of ultrasound use in peripheral vascular interventions (PVI) is inversely related to access site complications. Given all of the data supporting the usage of UGVA across numerous specialties, our findings encourage the consideration of an ultrasound-first approach for vascular access in PVI and the implementation of targeted strategies and evidence-based guidelines to enhance UGVA utilization in PVI.
