The financial relationships between the pharmaceutical and device industries and healthcare practitioners appear frequently in the spotlight because of their potential to create bias and influence prescribing choices. Public disclosure of these transactions may help patients make informed choices about their healthcare practitioners and may help reduce healthcare costs. The US Sunshine Act, a Federal law that requires disclosure of transactions between industry and healthcare practitioners, was passed in 2010. Similar disclosure laws and codes now exist globally. Unfortunately, none of the current requirements are clear about the reportability of industry support for medical writing and editorial services. Regardless, medical writers should be aware of these requirements, which can help them as they forge relationships with authors.
