Source Files

The HCUP Maine inpatient files were constructed from the Maine Health Data Organization inpatient discharge files.

Types of Facilities Included in the Files Provided to HCUP by the Partner

These data include inpatient discharge data from general acute care hospitals, including psychiatric and rehabilitation hospitals.

A comparison of the number of hospitals included in the SID and the number of hospitals reported in the AHA Annual Survey is available starting in data year 2010.

Hospitals do not always report data for a full calendar year. Some hospitals open or close during the year; other hospitals have technical problems that prevent them from reporting data for all months in a year.

Inclusion of Stays in Special Units

The documentation provided by Maine does not indicate whether stays in special units within a hospital (e.g., psychiatric, rehabilitation, long-term care) are included in the data.

Exclusion of Records During HCUP Data Processing

Records with a discharge disposition of "still a patient" and "admitted as an inpatient" were excluded from the HCUP Maine inpatient data.
