Well, according to this article on PharmaLive, a survey discussed in JAMA's med ed issue give more evidence on why it's needed. A snip:
Nearly 60 percent (59.6 percent) of the students simultaneously believed that sponsored grand rounds are educationally helpful and are likely to be biased. Students at one school who had attended a seminar about drug company-physician relationships were no more likely than the non-attending classmates to show skepticism. Of the respondents, 85.6 percent did not know if their school had a policy on these relationships. In a national survey of student affairs deans, among the 99 who knew their policy status, only 10.1 percent reported having school-wide policies about these interactions.
Credit card companies hook college students to get long-term customers. Does anyone think that pharma companies don't do the same thing, albeit in a different way? Let's teach the next generation of physicians to be independent thinkers, as well as good docs (and can they even be good docs if they're not independent thinkers?).
