The Massachusetts Center for Health Information and Analysis' (CHIA) mission is to monitor the Massachusetts health care system and to provide reliable information and meaningful analysis for those seeking to improve health care quality, affordability, access, and outcomes. CHIA is responsible for the Massachusetts All-Payer Claims Database (APCD) and the Acute Hospital Case Mix Databases (Case Mix Databases). CHIA also currently develops, fields, and reports results from two surveys to explore insurance, affordability, and access in Massachusetts – the Massachusetts Health Insurance Survey (MHIS) which surveys individuals about their insurance status and experience accessing care, and the Massachusetts Employer Survey (MES), which surveys employers about their offering of coverage to employees. CHIA is currently reviewing the extent to which they can streamline these two surveys and part of this process involves talking to stakeholders and agencies and organizations that use their data.

JSI was contracted by CHIA to assist the agency with its use of external survey data resources – particularly national surveys – to inform future analysis and reporting of employer offerings and population coverage and access in MA.

The goals of this project are to identify secondary data sources that could inform CHIA’s analysis and reporting of health coverage, access, and affordability in MA and employer offering of coverage. These national secondary data sources will potentially supplement CHIA data sources to provide reliable and meaningful metrics. In collaboration with CHIA, JSI will finalize a list of metrics and their corresponding national data sources that are methodologically rigorous/sound, can be used for future monitoring, and could inform policymaking and support health system change. JSI is utilizing a mixed method approach to complete, including a literature review, interviews with data stewards and users, and exploratory analyses of identified secondary data sources.
