A retrospective cross-sectional study was conducted to quantify trends in ophthalmology practice consolidation in the United States from 2015 to 2022. The study found that there was a decrease in the number of ophthalmologists and practices, while the percentage of ophthalmologists in larger group practices increased. Consolidation trends were significant across all regions, sexes, and years of experience in practice.
Purpose: To quantify trends in ophthalmology practice consolidation in the United States. Design: A retrospective cross-sectional study. Participants: Providers in the Centers for Medicare and Medicaid Services (CMS) National Downloadable File with a primary specialty designation of ophthalmology. Methods: We used the CMS database to determine national practice consolidation trends in ophthalmology on individual physician and group practice levels and analyzed by region, sex, and years spent in practice. We used the Cochran-Armitage test to determine the statistical significance of practice size differences between 2015 and 2022. Main Outcome Measures: Temporal practice size trends for physicians and practices in ophthalmology and regional, sex-specific, and age-related trends. Results: Between 2015 and 2022, the number of ophthalmologists decreased from 17 656 to 17 615 (e0.2%), whereas the number of practices decreased from 7149 to 5890 (-18%). The percentage of ophthalmologists in practices of 1 to 2 members decreased from 35% to 28%, whereas those in groups of 50 or more increased from 7% to 11%. The percentage of practices with 1 to 2 members decreased from 75% to 71%, and those with 50 or more increased from 0.2% to 0.4%. Consolidation trends were significant on individual ophthalmologist (P < 0.001) and group practice (P < 0.001) levels. All regions, sexes, and subgroups of years spent in practice demonstrated consolidation (P < 0.001). The Northeast showed the greatest increase in groups of 50 or more physicians (thorn7%) between 2015 and 2022. Proportionally fewer female than male ophthalmologists were associated with practice sizes of 1 to 2 members in 2015 (29% and 36%, respectively) and 2022 (23% and 30%, respectively). Proportionally fewer ophthalmologists with 0 to 10 years of experience in practice were associated with practice sizes of 1 to 2 members than those with more than 30 years in practice in 2015 (18% and 48%, respectively) and 2022 (14% and 40%, respectively). Conclusions: Ophthalmology has undergone practice consolidation from 2015 to 2022. A decrease in the proportion of physicians affiliated with smaller practice sizes seems to have occurred.
