Few women are on the list of doctors paid the most money by drug and medical device companies last year, according to a ProPublica analysis of new data released by the federal government. More than 90 percent of the 300 doctors who collected the most money for speaking and consulting are men, based on information from the new government database, called Open Payments. By comparison, men accounted for about 68 percent of active physicians in the United States in 2012, according to the Association of American Medical Colleges. What we found adds to a growing body of evidence that male and female doctors are paid differently and may in fact practice medicine differently, though the reasons for the discrepancy are not completely clear.
