Hospital and Emergency Department Discharge Data

Welcome

Hospitals keep records every time a person is discharged (released) from an inpatient hospital or emergency department (ED). These records include important information such as the reason they were admitted, diagnoses that were made, and care that was delivered. Hospital and emergency department discharge data are used by researchers and policymakers to understand trends in hospital services and the health conditions experienced by people in Oregon.

The Hospital Reporting Program maintains a dashboard of Hospital and Emergency Department Discharge data. Explore the Oregon Hospital Discharge Data Dashboard to learn more.

Public datasets

The Office of Health Analytics makes public use files of patient hospital discharges available for a variety of purposes. The data has been de-identified using the Health Insurance Portability and Accountability Act Privacy Rule's Safe Harbor standard for de-identification. As a result, full 5-digit zip code information is not available in public use files.

Annual data files are available in comma-delimited format, accompanied by documentation, for calendar years 2008 through 2024 for inpatient discharges and 2020 through 2024 for emergency department discharges. The cost is $250 per year or $75 per quarter of data requested. The number of discharges varies by year, but are generally in excess of 350,000 records per year for inpatient discharges and 1,300,000 records per year for emergency department discharges.

Before requesting public use datasets, please review our FAQ document. Please also review the inpatient hospital discharge layout and example data sets for inpatient and/or emergency department discharges to ensure the variables are sufficient for your needs. The Office of Health Analytics will not refund fees.

To request public use datasets, please visit the Health Analytics Data Request page. After completing the request form, you will receive an email with Form D-1 to complete and instructions for mailing your completed form and payment in the form of a check.

Research datasets

More detailed information for research and analysis purposes can be obtained from Healthcare Cost and Utilization Project (HCUP) Central Distributor

HCUP datasets are not fully de-identified and will require a data use agreement, study proposal, and plan for maintaining confidentiality for access. Be aware that:

The costs varies by year requested, but averaged about $1200 per year.
Researchers and all other persons with access to the data are required to read and sign an agreement with HCUP.
Please refer to the HCUP website for further information on ordering, payments and data use requirements.

The Oregon Health Authority provides custom datasets for academic research and county public health use when discharge data from HCUP is not suitable. For more information and to indicate interest in requesting discharge data, please visit the Health Analytics Data Request page. If you have additional questions about the available data, please email HDD.Admin@odhsoha.oregon.gov.
