CHIA has launched a new report series providing analyses and trends sourced from the Massachusetts Acute Hospital Case Mix Database. The first report, published in December 2020, offers new insights into hospital inpatient utilization patterns in the period leading up to the outbreak of COVID-19. Massachusetts Acute Care Hospital Inpatient Discharge Data (FFY 2016-2019) presents key measures of inpatient utilization overall and by hospital, patient, and discharge characteristics.
This report establishes an important baseline of inpatient utilization that can be used for public health initiatives, analyses of preventable hospitalizations and readmissions, and comparative cost and outcomes research. To better understand the vital role of inpatient services in the continuum of health care services in the Commonwealth, CHIA has analyzed inpatient stays in Massachusetts acute care hospitals over a four-year period, from Federal Fiscal Year (FFY) 2016 to FFY 2019.
Under state law, CHIA maintains a database of stay-level encounters with acute care hospitals going back more than 20 years. Collectively known as Case Mix, the databases capture each inpatient admission, emergency department visit, and outpatient observation stay at an acute care hospitals in Massachusetts. Case Mix captures the medical reason for the visit, procedures and services provided, charges incurred, and duration of the visit, as well as patient demographics.

In addition to this report, CHIA has recently released the Massachusetts Acute Care Hospital Emergency Department Data (FFY 2016-2019) report and is developing a report for outpatient observation stays to be published in 2021.
