Surgeon demographic and surgical volume trends in adult strabismus surgery in the United States.

PURPOSE: To explore the influence of career stage, gender, and age on procedural trends of surgeons performing strabismus surgery. METHODS: Data on ophthalmologists who performed strabismus surgery and on the Medicare beneficiaries who underwent surgery between 2012 and 2017 was retrieved from Medicare Provider Utilization and Payment Data. RESULTS: A total of 133 strabismus surgeons (78.9% male and 21.1% female) were reimbursed by Centers for Medicare and Medicaid Services for 10,598 strabismus procedures during the study period. The overall number of strabismus surgeries increased (P = 0.039) over time. Most surgeons were 50-59 years of age (n = 45 [33.8%]), with an average age of 54.5 ± 9.5 years. The number of services per physician did not differ by gender (85 ± 97 procedures/male surgeon and 60 ± 149 procedures/female surgeon [P = 0.13]). There was no difference in the gender proportion of physicians, with 0-9 post-fellowship years of experience (P = 0.32), but there were significantly more men with 10-19 (P = 0.003), 20-29 (P < 0.001), and 30-39 (P < 0.001) years of post-fellowship experience. There was no difference in the number of procedures performed between women and men 30-39 (P = 0.83) or 60-69 (P = 0.48) years of age; however, women 40-49 (P = 0.009) and 50-59 (P < 0.001) years of age performed significantly fewer procedures per surgeon than men. CONCLUSIONS: Women performed significantly fewer surgeries midcareer compared to their male counterparts.
