Racial and ethnic disparities in health care access, quality, and outcomes have been well documented in Massachusetts and across the country. Solutions for reducing inequities in health require investments of time and resources for which there will always be competing priorities. In understanding the value of these investments, it is critical to recognize that in addition to the human toll, they represent a significant economic burden to individuals and families, health care providers, employers, public and private sector payers, and the overall Massachusetts economy. This study, commissioned by the Blue Cross Blue Shield of Massachusetts Foundation in collaboration with the Health Equity Compact, aims to quantify that economic burden.
