BACKGROUND: Practice consolidation by vertical and horizontal integration is a growing trend in surgery. Practice consolidation has not been previously examined in vascular surgery. METHODS: The Medicare Provider Enrollment, Chain, and Ownership System data were used to identify vascular providers and vascular surgery practices in the United States in 2015 and 2020. Practices were categorized as solo (1 surgeon), small (2), medium (3-5), and large (≥6). The number of providers and the number of practices in each size group were determined. The Hirfendahl-Hirshman index (HHI), a measure of market consolidation, was calculated. Provider count, practice size, and HHI were additionally analyzed by urban and rural regions. All values were calculated for each time point and compared. RESULTS: Vascular providers increased in number from 2929 to 3154 (7.7%) from 2015 to 2020. The number of practices decreased from 1351 to 1090 (19.3%). The number of large practices increased by 49.4%; the number of small or solo practices decreased by 42.1%. The mean HHI increased from 0.486 in 2015 to 0.498 in 2020. Both urban and rural regions had a decrease in solo practices (43.3% and 2.3%, respectively) and an increase in HHI (from 0.499 to 0.509 and 0.793 to 0.818, respectively). All changes were statistically significant. CONCLUSIONS: From 2015 to 2020, there is a trend toward vascular providers working in larger practice groups and a corresponding increase in measures of market consolidation.
