April 8 (Bloomberg) -- Johns Hopkins University’s medical school has adopted guidelines restricting interactions between doctors and makers of drugs and medical devices.

The policy, which takes effect July 1, prohibits Hopkins doctors from accepting gifts and meals and limits consulting agreements and appearing at industry-sponsored events, the school in Baltimore said today in an e-mailed statement.

Johns Hopkins Medicine new guidelines follows Stanford University’s School of Medicine, near Palo Alto, California, which announced April 1 that faculty income from consulting with outside groups and royalty payments from inventions will be posted on a school Web site. U.S. Senator Charles Grassley has criticized the medical schools at Stanford, Harvard University in Boston, and Emory University, in Atlanta, for not disclosing industry payments.

Hopkins’ new rules bars gifts of meals of any value and prohibits consulting positions “that carry personal compensation but no real duties,” the statement said. Starting in 2010, the university will also ban free pharmaceutical samples, with exceptions made in some cases for drugs that can be given without the manufacturer’s name.
