About this dashboard

This dashboard reports on people who received services for substance use disorders. Information on these pages represent data reported to BSAS by service providers that have a contract with BSAS. As such, data presented here is not representative of all addiction services in Massachusetts.

Data available include demographics of individuals served, services provided, and the primary substances for which services were targeted. It contains an Overview report, which is a summary of 3 more detailed views about:

  • Comparisons: Demographics, substance use history, service type, and enrollment time period for different populations served.
  • Trends: Trends in enrollment over time filtered by population, time period, residence, and primary substance.
  • Maps: Distribution of enrollments by EOHHS region, county, and city/town where available.

Note: Additional notes on the data and functionality are available within the dashboard itself. Look for the "?" icon throughout the dashboard, and hover over to show additional information on the various dashboard components.

To use this dashboard, open the menu in the upper left and select one of the reporting views. Click on the dashboard title to return to the Overview. We highly encourage users to review the dashboard tutorial document where they can find more information on using the dashboard and other frequently asked questions.

If your analysis results in too many suppressed cells, consider expanding your time period and/or remove some of the filters.

The Bureau of Substance Addiction Services (BSAS) collects and organizes data from new services. The funding and management of some of these services might be transferred to other state agencies, following which the admission data may no longer be submitted to BSAS.
