Opening Message 

CHIA has been busy these past few months, as the weather slowly turns to summer!

CHIA released a new research brief on the intersection between citizenship/immigration status of Massachusetts residents and health insurance coverage rates in the state. This brief is the latest installment in CHIA’s reporting series focused on health equity.

Earlier this month, CHIA reported on hospital financial performance and utilization through the annual Hospital Profiles publication, which provides information on acute and non-acute hospitals over a five-year period through HFY 2021; quarterly updates to the Hospital Inpatient Discharge Data (HIDD) dashboard and a new Emergency Department (ED) data dashboard were also launched.

CHIA’s work to produce the Hospital Profiles is featured in the “Data User Profile” section of this newsletter to highlight how CHIA uses multiple data sources to create a comprehensive view of hospital performance.

As always, the “Publications and Data Releases” and “Upcoming Events” sections of DataMatters will keep you updated on reports CHIA has released recently and events of interest to the local health data community.

We also want to know your thoughts about this newsletter—things you like, things you would like to see included, suggestions for future user profiles. Please email us at

Datamatters May 2023 Emergency Department Dashboard


Today we wanted to highlight one of CHIA’s more recent publication series. Since 2020, CHIA has produced annual reports providing analyses and trends on health care utilization in the Commonwealth sourced from each of the Case Mix databases: hospital inpatient discharge data (HIDD), emergency department data (EDD), and outpatient observation data (OOD). The most recent annual report was published in December 2022 and was sourced from the HIDD dataset.

Last week, CHIA published its first-ever interactive dashboard on emergency department (ED) visits. This dashboard uses interim data to offer timely insights into ED utilization in the Commonwealth. It presents visit-level information at a statewide level and for select measures at the hospital level from Federal Fiscal Year (FFY) 2019 through the first quarter of FFY 2023 (October 2018 – December 2022).

CHIA recently also updated its hospital inpatient utilization analyses with quarterly data through December 2022. You can see the latest quarterly HIDD updates here. Going forward, CHIA will update both these interactive dashboards on a quarterly basis as the data becomes available.

We also want to remind our readers that the hospital fiscal year (HFY) 2022 hospital inpatient discharge database (HIDD) data is now available for public application. The data includes inpatient discharges from Massachusetts acute care hospitals for the period of October 1, 2021 – September 30, 2022


Data User Profile

In each DataMatters publication, CHIA features an interview with a CHIA data user. This time we decided to highlight an internal user of our data, CHIA’s Provider Finance team, to provide an in-depth look at how they use multiple datasets that CHIA collects.

Earlier this month CHIA published its most recent Hospital Profiles publication, a comprehensive analysis of Massachusetts hospital performance for hospital fiscal year 2021 (HFY 2021). This is a continually evolving publication, with newly designed profiles with consolidated information, in addition to an interactive dashboard which allows users to filter results by individual hospital, hospital type, among other measures.

We are grateful to CHIA staff for taking the time to answer some of our questions!


Please briefly describe the reports and analyses your team produces.

The Provider Finance team primarily produces or contributes to reports on hospital financial performance. This includes quarterly and annual reports, a five-year trend analysis, and annual Hospital Profiles. These reports also include the hospital health systems and affiliated physician organizations to help develop a more complete understanding of the financial performance of a hospital in the context of the larger health system it operates within.


What CHIA data do you use for Hospital Profiles? How is it collected?

Hospital Profiles compiles financial and utilization data from hospital cost reports, standardized financial statements, relative price, and inpatient discharge data. The data is either provider or payer submitted. Our team collects and analyzes the hospital cost reports and standardized financial statements. We receive relative price (RP) results and annual analysis of the data from other CHIA teams, in addition to receiving assistance on the appropriate metrics needed from the hospital inpatient discharge data (HIDD).

Prior to creating the individual Hospital Profiles, we prepare a data verification of the cost reports for the hospitals to review and either affirm or correct their submitted data. This includes sharing 5-year trends for a variety of financial and utilization metrics such as gross patient service revenues, net patient service revenues, beds, inpatient discharges, etc. Additionally, we review the standardized financial statements submitted against the audited financial statements to confirm all data is aligned and accurate.

For data collected outside of our team, such as RP or HIDD, we work with the appropriate teams within CHIA if any questions arise when comparing the current year to previous Hospital Profiles publications.


What do you look for when analyzing this data? What are some of the key metrics you use?

In reviewing the data, we look for any significant year-over-year changes for several metrics including discharges, revenues, hospital margins, etc. Additionally, we compare the hospital data to either the statewide or peer cohort medians whenever possible.

As the pandemic impacted many financial and utilization trends, we have utilized 5-year trends for most metrics to analyze how the data and trends were affected.


How do you envision stakeholders using Hospital Profiles?

The goal of Hospital Profiles is to provide information for each of the hospitals in an easy-to-read one-page format. This allows interested parties and stakeholders to have a factsheet immediately available to them about the hospital of their interest.

The interactive dashboard allows users to view the data from different cuts, such as by hospital type, hospital system, as well as individual hospital. This allows for more comparisons to other hospitals in the state.

Last, the databook includes all of the underlying data utilized and allows users access to all of the data at once if they want to perform their own analysis.
