In July 2012, after years of consideration, Massachusetts enacted wide-ranging health care reform legislation that aims to control costs and improve quality.5 A signature feature of the act, signed into law by Deval Patrick, the state's Democratic governor, on August 6, 2012, is the creation of an annual global spending target for total health care expenditures, which is tied to the growth rate of the state's economy. Massachusetts is the first state to set statewide benchmarks to control health care costs, albeit with limited enforcement mechanisms and targets that may slow the rate of increase of health spending, but not decrease it. Stricter provisions, such as a luxury tax on high-priced health care entities and restrictions on how health systems negotiate contracts with insurers, were removed from the final version of the act. Health care entities as defined in the act include clinics, hospitals, ambulatory surgical centers, physician organizations, accountable care organizations, and payers. Health care providers are defined as persons or organizations that provide medical or health services or that furnish, bill, or are paid for delivering such services.5
