A key Obamacare initiative to get hospitals and doctors to better coordinate patient care is "off to a strong start," federal officials said Thursday as they announced $380 million in savings from the program.

Those savings by the Accountable Care Organization program, which aims to hold down Medicare costs and improve patient outcomes, met original projections for the initiative's first year, officials said. And will provide incentives for other medical providers to form their own ACOs, they predicted.
