Care coordination effort tops 2,000 doctors

"We believe that by compensating physicians for placing an increased emphasis on helping their sickest patients, particularly those with multiple chronic diseases or at greatest risk for these diseases, measurable improvements in care quality and cost savings can be achieved," CareFirst President Chet Burrell said in a statement.

Similarly, the healthcare law establishes accountable care organizations to encourage better coordination. It splits savings from ACOs between Medicare and the ACOs themselves, as an incentive for doctors, hospitals and other healthcare providers to participate.

But stakeholders have raised serious questions about the proposed framework for ACOs. Several large, integrated clinics that are similar to ACOs have said they don't plan to take part in the program unless it is changed significantly.
