Physician characteristics, industry transfers, and pharmaceutical prescribing: Empirical evidence from medicare and the physician payment sunshine act.

Abstract

To evaluate physician characteristics associated with pharmaceutical industry transfers and prescribing behavior after public reporting under the Sunshine Act. 2014-2016 secondary data on industry transfers to physicians from the Open Payments Dataset supplemented with Medicare Part D prescription data, Medicare service data, and practice attributes from the Physician Compare Database. Using regression analysis with county/physician fixed effects, this study examines characteristics associated with the probability/magnitude of transfers and the association between transfers and prescriptions. Using an iterative matching approach, this study identifies physicians who delivered outpatient Medicare services in 2014 (n=409041) and tracks their annual transfers between 2014 and 2016 (N=1227123) across six transfer categories. In addition, it examines their Medicare Part D prescription behavior between 2014 and 2015 (N=741659). Industry transfers dramatically declined in 2015 and 2016. Transfers are significantly associated with increased prescription costs, branded prescribing, and prescribing for High-Risk Medications (HRMs). Industry transfers have declined after public reporting. Transfers are associated with higher prescription costs and incidence of HRMs. Future research is needed to determine the causal impact on quality and cost-effectiveness of prescribed medications.
