Post-industrial societies confront common problems in pharmaceutical industry-physician relations. In order to promote sales, drug firms create financial relationships that influence physicians' prescriptions and sometimes even reward physicians for prescribing drugs. Three main types exist: kickbacks, gifts, and financial support for professional activities. The prevalence of these practices has evolved over time in response to changes in professional codes, law, and markets. There are certainly differences among these types of ties, but all of them can compromise physicians' independent judgment and (...) rational prescribing.Drug firms have paid kickbacks for prescribing drugs, purchasing drugs, switching brands prescribed, adding a drug to a hospital formulary, enrolling patients in post-marketing clinical trials, and writing practice guidelines that encourage the use of certain drugs.

Public policy tries to promote appropriate drug use by allowing firms to market drugs in interstate commerce only for uses that the Food and Drug Administration has found to be safe and effective. Because of their medical knowledge, physicians are authorized to prescribe drugs even for uses unapproved by the FDA. Nevertheless, physicians have relied on drug firms for information on appropriate prescribing despite the inherent tension between drug firm dissemination of information to promote sales and rational prescribing. In the (...) past, physicians often relied particularly on drug firm advertising for information on drug use. Today, physicians rely on drug firms to finance continuing medical education. A historical review reveals connections between these two different ways commercial interests have influenced the information that physicians receive and points the way to needed reforms. (shrink)
