A Revival of Physician-Run, Group Model Managed Care?

In Florida, there are now a couple of "provider-sponsored organizations," which seem to be sort of a revival of the old physician-run, group practice model of managed care. The new organizations are nominally for-profit, but "the idea is to create a system in which a large group of physicians can deliver high-quality care under the direct supervision of physicians, not administrators trying to maximize profits." Sounds promising. See the story in the Miami Herald.
