By the time Djigui Keita left the hospital for home, his follow-up appointment had been scheduled. Emergency health insurance was arranged until he could apply for public assistance. He knew about changes in his medication — his doctor had found less expensive brands at local pharmacy chains. And Mr. Keita, 35, who had passed out from dehydration, was cautioned to carry spare water bottles in the taxi he drove for a living. The hourlong briefing the home-bound patient received here at the Hospital of the University of Pennsylvania was orchestrated by a hospitalist, a member of America’s fastest-growing medical specialty. Over a decade, this breed of physician-administrator has increasingly taken over the care of the hospitalized patient from overburdened family doctors with less and less time to make hospital rounds — or, as in Mr. Keita’s case, when there is no family doctor at all. – From NY Times
