Scope and nature of financial conflicts of interest between neurologists and industry

Objective To detail the scope and nature of financial conflicts of interest (COIs) between neurologists and the pharmaceutical and medical device industries (Industry) using the Centers for Medicare and Medicaid Services Open Payments (OP) database, with a focus on trends from 2013 to 2016.

Methods Payments from Industry to US neurologists were categorized into research payments, general (nonresearch) payments, and value of ownership in Industry. We performed descriptive analyses to detail the scope and nature of these relationships and trends over time.

Results At least 9,505 neurologists received at least one payment from Industry each year. From 2013 to 2016, 1.6 million payments totaled $354 million, of which 99.5% of payments and 85.6% of payment value were for general/nonresearch-related payments. Most neurologists (between 65% and 80%) received less than $1,000 per year, but over 200 neurologists each received more than $100,000 during some years. Several received over $1 million. General payments are increasing, research payments are steady, and neurologists' ownership and investments are decreasing.

Conclusions Neurologists have extensive financial relationships with Industry, though this is driven by a well-paid minority. As a profession, we must work to establish firm rules to manage these potential COIs, ensuring that relationships with Industry yield synergistic advances while minimizing bias and maintaining public trust.
