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.

CROWNWeb Reference Documents

The CROWNWeb reference documents listed below provide the logic and business rules for the CROWNWeb dataset. These definitions and rules are to be incorporated into the data file build-out.      

The Kidney Data Dictionary (KDD) was replaced by the ESRD Quality Reporting System Data Dictionary (EDD) in 2018 and can be located at the following website. The new data dictionary offers more detail regarding conditional logic and clearer definitions of the field values for both the manual data entry and the electronic data interchange methods.

The new dictionary does not provide the detail related to what fields are required and optional as the Kidney Data Dictionary provided for the CROWNWeb Schema for the xml files. Therefore, the KDD has been maintained for vendor and dialysis organization reference.

Download the most frequently requested tables from the Appendix section of the KDD (provided in an Excel format) for use when developing EMR capability for producing the CROWNWeb xmls.
