All Payer All Claims Data Requests

Data Request Overview

The All Payer All Claims (APAC) data request process varies depending on what type of data you are requesting. The flowchart below illustrates the request process for the different types of data available. Review the APAC Data Request Fact Sheet for more information about the data request process. To learn more about the Data Review Committee, view the Data Review Committee page.

APAC Data on Timely Topics

By design, APAC data are generally about 18 months old by the time they are released as final, but they have shed light on a range of important and timely topics, including:

  • Health impacts of wildfires
  • Balance or "surprise" billing
  • Health care costs
  • Emergency department use for mental health issues

APAC Vendor Transition

The APAC Program recently completed the transition to Human Services Research Institute (HSRI). What does this mean for data users? For more information, please consult these documents:

How to Obtain APAC Data

Public Use data set requesters must submit an APAC-2 form. The APAC-2 is reviewed by staff, a Data Use Agreement is executed and then the request is fulfilled. This process generally takes 2-4 weeks.

Limited data set requesters must submit an APAC-2 form. Staff review the APAC-2 and then prompt the requester to submit an APAC-3 form. The APAC-3 is reviewed by the Data Review Committee, a Data Use Agreement is executed and then the request is fulfilled. This process generally takes 2-4 months.


Enhanced APAC Data

All Payer All Claims (APAC) and Oregon death record data are now linked, supporting analyses and research about health care access, services and outcomes. These data are now available for request through a two-part process:

You may submit requests to the APAC program (Part A) and CHS (Part B) concurrently, and APAC and CHS will coordinate approval.  

The APAC program highly recommends that you contact us for a discussion and consultation prior to submitting your APAC-Death record linked data request.
