Provider directories form a critical capability that helps enable efficient sharing of health information and widespread interoperability. The Shared Nationwide Interoperability Roadmap includes a call to action to advance the nation’s provider directory efforts.

Participants also discussed issues with current technical standards for provider directories. Implementers have learned much from using the Healthcare Provider Directory (HPD) specification and its extensive data model, and promoted continued use of that data model. However, HPD’s cumbersome API based on yesterday’s technology has been a barrier to industry adoption. Fast Healthcare Interoperability Resources (FHIR) is seen by many as the future of healthcare interoperability, but may not support the complex relationships between individuals and organizations and does not support electronic service information. Despite these gaps, participants committed to an implementation guide for a provider directory API based on the FHIR framework in the near term and voiced support for FHIR as a common interoperability standard.
