The physician's role in this present-day notion of medicalization is similarly complex. On the one hand, the doctor remains an authority figure who prescribes pharmaceuticals to patients. However, in some countries, such as the US, ubiquitous direct-to-consumer advertising encourages patients to ask for particular drugs by name, thereby creating a conversation between consumer and drug company that threatens to cut the doctor out of the loop. Additionally, there is a widespread concern regarding the extent of the pharmaceutical marketing direct to doctors and other healthcare professionals. Examples of this direct marketing are visits by salespeople, funding of journals, training courses or conferences, incentives for prescribing, and the routine provision of "information" written by the pharmaceutical company.
