Earlier this year, the Center for Health Information and Analysis (CHIA) released its Annual Report on the Performance of the Massachusetts Health Care System for 2020.  The Massachusetts Legislature relies on CHIA data when considering bills to regulate drug costs and prices. The advocacy group Health Care for All reported that CHIA data showed prescription drug spending grew by 7.7 percent in 2020, more than twice the benchmark - but the most reliable data on prescription drugs indicates that spending in 2020 was essentially flat.
