Impact of US industry payment disclosure laws on payments to surgeons: a natural experiment.

Objectives: To compare changes in the number and amount of payments received by orthopedic and non-orthopedic surgeons from industry between 2014 and 2017.

Methods: Using the Centers for Medicare and Medicaid Services (CMS) Open Payment database from 2014 to 2017, we conducted a retrospective cohort study of industry payments to surgeons, including general payments and research payments.

Results: Among orthopedic surgeons, the total number of general payments decreased from 248,698 in 2014 to 241,966 in 2017, but their total value increased from $97.1 million in 2014 to $110.2 million in 2017. Among non-orthopedic surgeons, the total number decreased from 604,884 in 2014 to 582,490 in 2017, while the total value remained stable at approximately $159 million. Between 2014 and 2017, there was a differential increase in the median number of general payments received by non-orthopedic when compared to orthopedic surgeons (incidence rate ratio, 1.09; 95% CI, 1.08-1.09; p < 0.001), but a differential decline in the median value of general payments (- 8.9%; 95% CI, - 9.5%, - 8.4%; p < 0.001). Findings were consistent when stratified by nature of payment. In contrast, between 2014 and 2017, there was neither a differential change in the median number nor median value of research payments received by non-orthopedics.

Conclusion: Examination of a natural experiment of prior public disclosure of payments to orthopedic surgeons suggests that the Physician Payment Sunshine Act was associated with an increase in the number, but a decline in the value, of general payments received by non-orthopedic surgeons, but not on research payments received.
