Short Description

Review and test aspects of the FAST National Directory of Healthcare & Da Vinci Plan Net

Long Description

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.

Plan Net enables patients/consumers to see which providers and pharmacies are in-network for a given organization insurance plan.

These implementation guides are recommended by CMS as one way to comply with the  Patient Access API rule.

This track will continue the work of previous connectathon tracks and focus on testing:

Plan-Net IG:

  • The Plan Net profiles and Endpoints
  • General health care service, provider, and pharmacy search
  • Pharmacy mix
  • Ability to manage provider directory list for incoming/outgoing providers

Type

Review initial implementation guide work and test associated reference implementations and third party software

Specification Information

The FAST Directory Track will use following IGs as reference information.

FAST is in the process of combining the three National Directory IGs into a single IG (National Directory for Healthcare Providers and Services – NDH) based on feedback from the community. The combined IG is located at: HL7.FHIR.US.NDH\Home - FHIR v4.0.1

The working National Directory IG is built under the branch ming1, it could found at HL7.FHIR.US.NDH\Home - FHIR v4.0.1

While useful information may be found in these IGs: 

National Directory Exchange FHIR IG: https://build.fhir.org/ig/HL7/fhir-directory-exchange/

National Directory Endpoint Query FHIR IG: https://build.fhir.org/ig/HL7/fhir-directory-query/

National Directory Attestation and Validation FHIR IG: https://build.fhir.org/ig/HL7/fhir-directory-attestation/

Please use the combined IG as the basis for the National Directory / NDH IG standard.

Prerequisites

  1. Have read the National Directory and Plan Net IGs (linked above)
  2. Have registered for an account on Touchstone (reach out to one of the leads if you need help with this)
  3. FHIR Client

    Come prepared to interact with a FHIR Server.  This can be accomplished with an application that can be configured or coded to make FHIR RESTful calls.  See the "Step by step tutorial and sample projects" under the Helpful Links below for an example of how to do this use Postman.

    FHIR Server

    Come prepared for other FHIR Clients to be able to interact with your FHIR Server.

Testing Scenario:

Role 1 Name: National Directory Actor

Role 2 Name: Distributed Access/Workflow Directory

Role 2 Name: Application Query Actor


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


Scenario Step 1 Connect to National Directory API endpoint

Action: Query National Endpoint

Success Criteria:  ability to access National Directory API 


Scenario Step 2 Query for endpoint information for a specific Organization

Action: RESTful GET of endpoint information for a specific organization

Success Criteria:  ability to return endpoint information for a specific 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.
