On November 5, 2015, the Blue Cross Blue Shield of Massachusetts Foundation hosted a symposium for non-governmental users of the Massachusetts All-Payer Claims Database (MA APCD) administered by the Center for Health Information and Analysis (CHIA). This symposium updated users on the current state of the MA APCD, highlighted research that has been made possible as a result of the MA APCD, provided an opportunity to share best practices, and encouraged discussion about future opportunities to enhance the MA APCD in an effort to continuously support data-driven research and policy development in the Massachusetts health care sector. As a follow-up to the event, this summary, prepared by Amy Willis, Business Writing and Editing, highlights key takeaways and recommendations generated from the discussion.
