To cut healthcare costs, the Obama administration has advocated moving away from fee-for-service payments, which reward providers for doing more procedures, to a coordinated system that pays doctors and hospitals for doing better. Under that vision, providers would be given a few years to move to performance-based medicine, in which fees and results are published, money is directed to evidence-based therapies, and harmful errors such as preventable infections are reduced. But many are worried that the president's hopes to constrain costs could result in tepid half-measures on Capitol Hill, the Washington Post reports.
