2022 - 09 FAST National Directory US Realm & Da Vinci Payer Data Exchange Plan-Net

Review of the existing implementation guides that are part of input into the FAST Directory solution.  The existing implementation guides include the National Directory Exchange IG, the Endpoint Query IG and the Attestation and Validation IG. The FAST solution document outlines the direction that will be taken in creating the three new IGs that are part of the National Directory work effort at HL7.

The goal of the project is to create FHIR based standards for:

1) The exchange of validated healthcare directory information in a federated access environment based on the Validated Healthcare Directory standard localized for the US Realm using work completed for the PDex Plan Net FHIR IG (includes 11-14 in drawing below),

2) Query for FHIR endpoints from any federated directory instance (includes 15-16 in the drawing below), and

3) Submitting attested information to the validated directory and verifying the information against primary sources (includes 1-10 in drawing below).

This project is needed to provide standards for the population, validation, exchange and query of a federated access national healthcare directory.  It will:

1. Minimize the burden on providers in supplying this information to multiple payers, healthcare organizations, and professional societies
2. Improve the quality of demographic and relationship information associated with healthcare organizations and individuals,
3. Provide a reliable source of electronic endpoints to facilitate the exchange of healthcare information (e.g. patient records and referrals).  In particular, the standards will facilitate the creation, population, and use of a national resource to support the scaling of FHIR based exchanges to support more efficient and better informed delivery of health care services.

Role 1 Name: Federated Directory Actor

Role 2 Name: Application Query Actor

Use Case 1- Query the Federated Directory for a specific endpoint based on the name or ID of a payer organization

Scenario Step 1 Connect to Federated Directory API endpoint

Action: Query Federated Directory Endpoint

Success Criteria:  ability to access a Federated Directory API 

Scenario Step 2 Query for endpoint information for a specific Payer

Action: RESTful GET of endpoint information for a specific Payer organization

Success Criteria:  ability to return endpoint information for a specific payer organization

Scenario Step 3 Query Bulk Data endpoint 

Action: RESTful GET of streaming NDJSON file 

Success Criteria:  ability to return bulk data stream for a specific resource

Stretch Goal:  ability to query NDJSON bulk data from IPFS or BitTorrent

Security and Privacy Considerations:

FAST UDAP Security protocols required for some use case exchanges.

Plan-Net IG:

• General Search
• Provider Search
• Pharmacy Search
• Pharmacy Mix
• Plan Net Bulk Export

System roles:

• • • Payer acting as Server

• • • Third-Party App acting as Client

Role 1 Name: Server 

Server provides $export operation to enable Payer Provider Directory to be exported.

Role 2 Name: Client

Client makes $export request to download Payer Provider Directory.
