Focus on Provider Quality:
Selected Clinical Measures, 2018 and 2020
July 2022

As part of CHIA’s ongoing work to monitor health care quality in the Commonwealth, A Focus on Provider Quality: Selected Clinical Measures, 2018 and 2020 examines performance across a subset of metrics from the NCQA Healthcare Effectiveness Data and Information Set (HEDIS ®).

CHIA monitors and reports on health care quality using measures selected from the Commonwealth's Aligned Measure Set and Standard Quality Measure Set (SQMS), as well as other measures of interest. The metrics cross different domains of quality assessment, including:

  • Clinical Quality Measures
  • Hospital patient experience
  • Primary care patient experience
  • Maternity-related care
  • Hospital adherence to safe practices
  • Health care-associated infections
  • Mortality
  • Medication safety
  • Effective care processes


CHIA calculates quality performance on all-payer adult acute hospital readmissions by applying a standard methodology to the Massachusetts Hospital Inpatient Discharge Database. This measure is reported in CHIA's Annual Report on the Performance of the Massachusetts Health Care System. CHIA also displays quality information in a series of interactive online graphics found on this webpage.

For more information about the Commonwealth’s Aligned Measure Set, please visit the EOHHS Quality Measure Alignment Taskforce webpage.
