Abstract
The Patient Protection and Affordable Care Act of 2010 (ACA) is arguably the most significant health legislation enacted in generations. As remarkable a political and policy achievement as it was, what the reform will actually accomplish is largely yet to be determined. Whether it slows the growth of costs, increases access to care, or improves the quality of care will depend on how it is implemented. Although major components of the law do not go into effect until 2014, the fate of the ACA depends on the outcome of four key events in 2012.
