SID Notes

Source Files

Beginning in 1996, HCUP Oregon files were constructed from discharge files supplied by the Oregon Association of Hospitals and Health Systems.

The 1993-1995 HCUP Oregon inpatient files were constructed from the Office for Oregon Health Plan Policy and Research discharge files.

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

The Oregon files consist of discharge abstract data for inpatient stays from all member hospitals. Source documentation provided by Oregon indicated that discharges from Veteran's hospitals were included in the Oregon data in 1994. Beginning in 1995, discharges from Veteran's Administration facilities were not included.

Two hospitals from the State of Washington report their data to both Oregon and Washington data organizations. Beginning in 2000, these two Washington hospitals were excluded from the HCUP Oregon SID. Prior to 2000, inpatient data for these two Washington hospitals were included in both the HCUP Oregon SID and Washington SID.

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

Stays in special units within Oregon hospitals (e.g., psychiatric, rehabilitation, long-term care) are included in the source data and therefore in the HCUP inpatient database. However, these records cannot be identified.

Exclusion of Records During HCUP Data Processing

Records with a discharge disposition of "still a patient" were excluded from the HCUP Oregon inpatient data.
