Abstract
OBJECTIVE: To analyze the effects of health reform efforts in two large states--New York and Massachusetts. DATA SOURCES/STUDY SETTING: National Health Interview Survey (NHIS) data from 1999 to 2008. STUDY DESIGN: We take advantage of the "natural experiments" that occurred in New York and Massachusetts to compare health insurance coverage and health care access and use for adults before and after the implementation of the health policy changes. To control for underlying trends not related to the reform initiatives, we subtract changes in the outcomes over the same time period for comparison groups of adults who were not affected by the policy changes using a differences-in-differences framework. The analyses are conducted using multiple comparison groups and different time periods as a check on the robustness of the findings. DATA COLLECTION/EXTRACTION METHODS: Nonelderly adults ages 19-64 in the NHIS. PRINCIPAL FINDINGS: We find evidence of the success of the initiatives in New York and Massachusetts at expanding insurance coverage, with the greatest gains reported by the initiative that was broadest in scope--the Massachusetts push toward universal coverage. There is no evidence of improvements in access to care in New York, reflecting the small gains in coverage under that state's reform effort and the narrow focus of the initiative. In contrast, there were significant gains in access to care in Massachusetts, where the impact on insurance coverage was greater and a more comprehensive set of reforms were implemented to improve access to a full array of health care services. The estimated gains in coverage and access to care reported here for Massachusetts were achieved in the early period under health reform, before the state's reform initiative was fully implemented. CONCLUSIONS: Comprehensive reform initiatives are more successful at addressing gaps in coverage and access to care than are narrower efforts, highlighting the potential gains under national health reform. Tracking the implications of national health reform will be challenging, as sample sizes and content in existing national surveys are not currently sufficient for in-depth evaluations of the impacts of reform within many states. © Health Research and Educational Trust.
