What's New in Massachusetts Health Care

  • CHIA’s 2018 Annual Report includes a calculation of statewide, per capita health care spending in comparison to the state’s cost growth benchmark, as well as other indicators used to assess the performance of the Massachusetts health care system.

  • This report concentrates on the top 10 therapeutic classes of drugs, as ranked by total expenditures incurred during fiscal year 2015. These classes accounted for 71.3% of pharmacy expenditures during that time period. In addition to presenting average costs by therapeutic class, the report contains detailed pages for each class, showing average costs for the top five most frequently prescribed drugs within the class.

  • Enrollment Trends monitors health insurance coverage in Massachusetts, where coverage is defined by unique Massachusetts residents with primary medical membership in the 13 largest commercial payers, MassHealth (Medicaid), or Medicare. The August 2018 Enrollment Trends offers insights into changes in health insurance coverage in the Commonwealth from March 2016 through March 2018.

  • CHIA has released an unprecedented amount of procedure price data through a public dataset in an effort to promote greater transparency in the Massachusetts health care system.

    See CHIA's two separate but related transparency initiatives.

  • The Commonwealth recently launched a new user-friendly health care transparency website that offers information to help Massachusetts residents be more actively engaged in, and make better decisions about their health care.

CHIA has produced several interactive maps of Massachusetts health care data. These maps allow researchers to better understand variations in health care spending and utilization by displaying recent data on a town-by-town or regional basis.
