ABSTRACT: Importance:An increased awareness of the interactions between the medical industry and health care professionals may lead to lower health care costs and more effective health care practices. Objective:To assess the characteristics of industry payments made to ophthalmologists between 2013 and 2017. Design, Setting, and Participants:This analysis included data reported in the June 29, 2018, update of the Centers for Medicare & Medicaid Services Open Payments Database (OPD). The OPD contains public records of industry payments made to physicians and teaching hospitals from August 1, 2013, to December 31, 2017, as reported by the medical industry. All general or research payments distributed to US ophthalmologists and contained in the OPD were included in this study. Data are summarized by practitioner, manufacturer, payment category, and geographic location. Main Outcomes and Measures:Main outcomes were the distribution, quantity, and value of payments made to ophthalmologists practicing in the United States or US territories. The financial characteristics of payment category, manufacturer, product, and location were also assessed. Results:This analysis revealed that the OPD showed industry reporting a total of 20?943 ophthalmologists receiving 736?517 payments worth $543?679?603.53 (1.67% of all industry-reported funds in the OPD). The median payment value was $22.44. Most payments were for food and beverages (581?588 [78.96%]), whereas most funds were allocated toward research ($310?142?151.88 [57.05%]) and consulting fees ($73?565?327.71 [13.51%]). The median payout to each ophthalmologist was $637.75 (interquartile range, $167.33-$2065.54). California was the highest-grossing state, receiving $101?135?980.34 (18.60%) of all payments. Fifteen companies were responsible for 87.68% of all funds distributed ($476?719?470.11) and were mostly involved in the production of pharmaceutical agents (anti-vascular endothelial growth factor agents, glaucoma eyedrops, and ocular lubricants) and surgical devices (cataract and glaucoma). Conclusions and Relevance:Although there is no way to know the veracity of these reports, the findings suggest the financial ophthalmologist-industry relationship is substantial. These relationships may be adding to health care costs and affecting the quality of care, although those associations were not evaluated in this study.
