Donald Berwick, an MD researcher who has focused on quality improvement has been nominated by President Obama to head the Center for Medicare and Medicaid (CMS) services. This is a key role in implementing the changes recently passed, and particularly in getting straight the Independent Medicare Advisory Community. He is very much a policy/researcher insider, as opposed to a politician. Here is the web site of the organization he now directs, Institute for Health Improvement. However, I am sure his confirmation hearing will be bumpy in the Senate.
While the public will pay less and less attention to health policy (a truly tragic turn of events), the hard work of implementation and making the system work better is just starting.
