Sen. Chuck Grassley (R-IA) asked eight journals to provide information about their medical ghostwriting practices and policies, in an effort to “shed light on the role companies may play in the dissemination of information about their products through medical literature.”

Grassley’s most recent probe into ghost writing practices took the form of a letter sent to the the Annals of Internal Medicine, New England Journal of Medicine, JAMA and others. The letter requested that publishers detail their policies with respect to third parties involved in the “development and/or writing of a journal article,” and any actions taken against authors for failing to disclose this info.
