All Payer All Claims (APAC) data and Oregon death record data are now linked.

APAC Transitioning to New Data Vendor

The All Payer All Claims (APAC) Program is contracting with Human Services Research Institute (HSRI) for a new solution for APAC data. The solution will encompass data submitter communications, receipt and validation of files, and access to data by state staff through a data enclave.

  • ​Data created in the HSRI solution will not match files created in the Milliman solution due to different algorithms for assigning unique individual identifiers for members and providers.
  • Data on member county of residence at the time services were received will be available. This means that it will be possible to show county-level trends, although file sizes may be larger. 
  • Transparent data enhancements. APAC will share the source field and all transformation code/logic for enhancements that do not rely on third-party proprietary software and data transformations. APAC cannot violate third-party proprietary interests.
  • Some data enhancements may not be available. Milliman’s proprietary data enhancements will not be available in the HSRI solution. Third-party and national measures, including most, if not all, of the Evidence-Based Measures (EBMs) will be recreated in the new solution.
  • New data elements workbook and data dictionary.
  • Reduction in duplicative data elements. APAC will maintain the usability of the data while discontinuing data elements that do not add value. 
    • ​For example, data on PEBB or OEBB coverage are received from data submitters in two fields but currently stored/available in four different and redundant data elements. 
  • Use by Oregon agencies will continue to the extent possible throughout the process. Please contact for more information.​

  • ​APAC research analysts will work with HSRI to design the structure for the data tables that best meets our needs.
  • Public Use Files will continue to be available for request.
  • Limited data sets will have new temporary restrictions based on timing. Contact​ to discuss your specific situation.
    • For less complex requests that can be reviewed and completed quickly, APAC anticipates accepting applications through August 2020.
    • For more complex requests including those requesting restricted data elements or that have a matching or linking requirement, APAC will likely be unable to complete new requests until early next year. These requests generally take several months to review and process. APAC staff will not have access to data in the current solution after mid-December 2020.
    • Data in the new solution will be available in March 2021.
  • APAC will publish the new data elements workbook and data dictionary as soon as available. Upon publication of the new data elements workbook, we will work with data requesters to prepare requests to be fulfilled as quickly as possible once full data become available in March 2021.​

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.

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.
