Previously, the Division of Health Care Finance and Policy, the predecessor to CHIA, published the Hospital Summary Utilization Data Files (HSUDF). These summary files were based on the following datasets – hospital discharge, outpatient observation visit, Emergency Department visit and 403 Cost Reports. Release of these summary data files has been discontinued. Files for FY 2005-FY 2010 are available from CHIA upon request by contacting the Center's public records office at public.records@state.ma.us.
