Almost six in ten doctors in the US received more than $12 billion in payments from pharma firms in the past decade, an analysis has revealed. A study by researchers at Yale University found that 57 percent of doctors earned the huge sums from manufacturers in relation to medical drugs or devices between 2013 and 2022. Most of the money was for consulting services or fees for things such as serving as a speaker at a venue, but the physicians also received large amounts of money for food and beverages and gifts. Orthopedic surgeons were found to receive the largest total sum of payments, at $1.36bn, and the most common drugs related to payments were blood thinners Xarelto and Eliquis. 'Despite evidence that financial conflicts of interest may influence physician prescribing and may damage patients' trust in medical professionals, such payments remain pervasive,' the researchers wrote. After orthopedic surgeons, the physicians that received the largest total sum of payments were neurologists and psychiatrists, who received $1.32bn, and cardiologists, who got $1.29bn. Although the median payment to doctors was $48, payments to the top 0.1 percent of doctors were far higher and differed depending on specialty. The average amount paid to the top 0.1 percent of orthopedists was $4,826,944. For the top 0.1 percent of cardiologists, it was $3,197,675, and for the top 0.1 percent of neurologists and psychiatrists it was $2,588,819.
