Industry marketing payments to physicians and prescription patterns for sacubitril/valsartan in the USA.

Abstract

Objectives: Although financial interactions between physicians and pharmaceutical and medical device companies could be potential conflicts of interest, in certain instances, industry promotion targeted at physicians may facilitate the early adoption of effective, novel care for patients such as sacubitril/valsartan in the USA. This study aims to evaluate associations between industry-sponsored meal payments to physicians and their prescribing patterns for sacubitril/valsartan in the USA.

Methods: Using the publicly accessible Centers for Medicare and Medicaid Services Medicare Part D database and the Open Payments Database, this study assessed associations between industry-sponsored meal payments to physician prescribers and total amounts of Medicare claims and spending for sacubitril/valsartan between 2015 and 2021.

Results: Among 220 147 eligible physician prescribers, 60 568 (27.5%) received at least one meal payment related to sacubitril/valsartan from the manufacturer, totaling US$13.9 million. The receipt of meal payments was significantly associated with a higher proportion of sacubitril/valsartan prescriptions to all sacubitril/valsartan, angiotensin receptor blocker and angiotensin-converting enzyme inhibitor prescriptions, with an OR of 2.04 (95% CI: 1.98 to 2.10, p<0.001). Moreover, a 10% increase in the annual number of meal payments was associated with a 2.6% (95% CI: 2.5% to 2.6%, p<0.001) increase in the annual number of Medicare claims and a 7.3% (95% CI: 7.1% to 7.5%, p<0.001) increase in annual Medicare spending per physician.

Conclusions: Given the underprescription of sacubitril/valsartan in the USA, the positive associations between meal payments and physicians' prescribing patterns suggest that industry-sponsored meals may contribute to the early adoption of this cost-effective, novel heart failure drug among US Medicare beneficiaries.
