The Medscape Physician Compensation Report is the most comprehensive and widely used physician salary survey in the United States for the eighth year in a row. Over 470,000 US physicians have used this report to access not only salary information, but also important factors affecting income, such as hours worked, time spent with patients, what they find most rewarding—and most challenging—about their jobs, and more. More than 20,000 physicians in more than 29 specialties responded to this year's Medscape compensation survey.
