Source Files

The HCUP Iowa inpatient files were constructed from the Statewide Database provided by the Iowa Hospital Association.

Which Hospitals

Iowa supplied discharge abstract data and some uniform bills for acute inpatient discharges from member hospitals.

Not all hospitals report a full calendar year of data. Some hospitals close during the year; other hospitals have technical problems that prevent them from reporting a full year.

Inclusion of Stays in Special Units

The documentation supplied by the Iowa Hospital Association indicates that the data include stays in acute exempt units, but exclude stays in swing bed and long-term care units.

Exclusion of Records

Beginning in data year 2001, the Iowa Hospital Association prohibits the release of two types of discharges:

  • HIV Infections (defined by MDC of 25) and
  • Behavioral Health including chemical dependency care or psychiatric care (defined by a service code of BHV).

These discharges were not included in the source file provided to HCUP and are therefore not included in the HCUP files.
