The care of Americans with severe chronic illnesses is disorganized, unnecessarily costly, and undisciplined by sound clinical science. The federal government should invest in a crash program to improve the scientific basis of managing chronic illness, and the Centers for Medicare and Medicaid Services (CMS) should extend its pay-for-performance (P4P) agenda to ensure that within ten years all Americans with severe chronic illnesses have access to accountable health care organizations providing evidence-based prospective care. This paper recommends a strategy for achieving this goal.
