Johns Hopkins, Yale, Harvard, Columbia and Cornell. What do these medical schools have in common? Beyond their first-rate reputations, they're also on the short list of top U.S. med schools that don't have departments of family medicine. Elite schools have long focused on training specialists and researchers, but with the federal health law's emphasis on primary care, some schools are looking harder at family medicine. Until this year, for example, the Mount Sinai School of Medicine in New York had neither a department nor any family physicians on staff.
