text: impractical.  Many if not most doctors, even family docs, are involved at least part time in research,  unpaid.  Much of this research is funded or even performed by pharmaceutical companies. Not to mention the scientists doing the research work for said companies full time are also physicians themselves.  and further, the pharma companies themselves get important feedback from physicians regularly.  Instead there exists rules about disclosure of said connections in any continuing ed presentation, and in any peer reviewed articles about who works for whom, and which company provided funding, so any biased interest is transparently visible.  Remember that the pharmaceutical industry is of vital importance to the health care system, to the health of the citizens.
