FHIR Server for National Healthcare Directory Resource


IRIS’ newest FHIR venture comes from the joint FHA and Office of the National Coordinator for Health IT (ONC) Healthcare Directory Effort. This project seeks to: (1) define the architecture of a proposed national resource of validated healthcare directory data, and (2) develop an HL7 Fast Healthcare Interoperability Resources (FHIR) Based Implementation Guide, Validated Healthcare Directory (VhDir) Implementation Guide (IG), describing the exchange of information between a national resource of validated healthcare directory data and local environments (e.g. provider organizations, payers, HIEs).

The proposed national resource would include a broad set of provider data that supports a variety of healthcare directory use cases. Data would be validated against primary sources (e.g. state licensing boards for licensure information) and available to local environments through a national exchange standard. Providers would only have to attest to much of their information once for the national resource, rather than for each local environment. The draft VhDir IG has been developed and sent to FHIR for V4 Ballot.

The IRIS’ FHIR team is developing the “first iteration” of a FHIR server that supports the that will be used as the foundation for future work. The team has gathered requirements and is in the process of reviewing the VhDir IG specification to determine which of the balloted resources can be developed within the specified timeframe.


Program Management,  Project Management


  • Evaluate and recommend the most appropriate FHIR API server for this project

  • Determine the level of effort for any upgrades to V4 if the previous object is not a V4 implementation.

  • Build resources as expressed in the IG, and implementation of “get” transactions only

  • Develop and provide the initial population of any new data structures that support these implemented resources

  • Identify and record issues uncovered in the implementation guide during server development

  • Publish source code in an opensource code repository such as GitHub

  • Deliver installation instructions over and above that required for the base product that this development extended
