NRAA HIE CROWNWeb Certification for EHR Vendors

The NRAA HIE facilitates a process for electronic health record (EHR) vendors to become certified to electronically submit data to the CROWNWeb repository through the NRAA HIE.  This certification demonstrates the vendor has the technical capability to support this process and once certification is obtained may promote this capability as a feature of their software.

The certification process consists of several preparation and testing steps to submit production data to CROWNWeb through the NRAA HIE. This process includes:

  • Preparing data files to meet the CROWNWeb format and business rules requirements
  • Testing for conformance
  • Testing for data content and business rule compliance
  • Connectivity and end-to-end testing

A complete overview and listing of steps in the certification process are outlined in the NRAA HIE CROWNWeb Certification Guide.
