FY2009-FY2013 Acute Hospital Utilization Trends
in Massachusetts Report

FY2013 Databooks

The Acute Hospital Utilization Trends in Massachusetts FY2009-FY2013 report offers inpatient, emergency department, and observation stay utilization statistics for Massachusetts residents who have been discharged from Massachusetts acute care hospitals for the period beginning in October 1, 2008 to September 30, 2013 (Hospital Fiscal Year 2009 through 2013).

In addition to a statewide report, there are eight regional summaries based on hospital service areas: Cape and Islands, Central MA, Metro Boston, Metro South, Metro West, Northeast MA, Southcoast, and Western MA.

The statewide and regional reports include high level demographic information based on American Community Survey (ACS) data to highlight potential population-based drivers of utilization trends found in the report.

To accompany the reports, CHIA developed comprehensive databooks that include aggregated FY2013 data on discharges by hospital sites, MS-DRGs, principal diagnosis codes, payer type categories, age groupings, total charges, and average charges.

Please note: This analysis was produced using CHIA’s Acute Hospital Case Mix Data which are comprised of patient level discharge data submitted by Massachusetts acute hospitals prior to payment by a public payer or private insurer.
