Background: The Open Payments program discloses industry payments to identified physicians (‘physician payments’). We characterize these payments by oncology specialty. Methods: We analyzed the December 2014 release of Open Payments data on physician payments made from August-December 2013. We characterized physician payments by type (general or research). We also evaluate physician ownership interests in reporting manufacturers. Data were aggregated by physician and oncology specialty [medical oncology (hematology/oncology, medical oncology, pediatric hematology/oncology); radiation oncology; and surgical oncology (surgical oncology, gynecologic oncology)]. We compared the number of physicians receiving payments to the total number of active physicians in each specialty in 2012 (AMA. Physician Characteristics and Distribution in the US. Chicago: AMA; 2014). Results: There were 82,213 payments to 9,893 oncology physicians (50% vs. 46% for all medical specialties) totaling $31 million (‘M’), Table. Payments for food/beverage were most common (79%) but represent only 10% of the total value. The most common nature of payment by total value was compensation for services (excluding consulting and CME) in medical oncology (38%), consulting fees in radiation oncology (30%), and education in surgical oncology (27%). Ownership interests totaled $8M in amount invested and $12M in total value of interest. Medical oncology had the highest proportion of physicians with ownership interest (1.7%) of oncology specialties. Conclusions: These data can inform policy-making and advocacy efforts for oncology specialties. Partially supported by the NIH (Grant TL1TR00098).
