HPD USA National Extension Wiki Specification

HPD USA National Extension Wiki Specification

This page is what will soon become the USA National Extension specification proper. The broader context for this effort can be found in the wiki page Healthcare Provider Directory USA National Extension.

Required Queries

Implementers declaring conformance to the HPD USA National Extension MUST support the following queries.

From the S&I Framework:

1. Retrieve a list of individual providers with specific individual attribute(s)
   • This use case might be used to retrieve a list of Spanish-speaking cardiologists within a specific ZIP code.
2. Retrieve information on a specific individual provider
   • This use case might be used to retrieve the phone number, address, or Direct address for a specific provider by name or other unique attribute.
3. Retrieve a list of individual providers with specific individual attribute(s)
   • This use case might be used to retrieve a list of dermatology clinics within a specific ZIP code.
4. Retrieve information on a specific organization
   • This use case might be used to retrieve the phone number, address, or organizational relationships for an organization by legal name or other unique attribute
5. Retrieve the list of organizations for a specific individual provider
   • This use case might be used to retrieve the hospitals with which a specific provider has a relationship, such as admitting rights.
6. Retrieve the list of individuals for a specific organization
   • This use case might be used to retrieve the orthopedic surgeons associated with a specific hospital.
7. Retrieve a list of individuals and organizations with specific attributes
   • This use case might be used to retrieve all of the Spanish-speaking cardiologists with admitting rights to a hospital within a certain ZIP code.

Based on our discussions to date:

1. Find information on an individual provider.
   • The information found will be based on the HPD data model and required attributes in it. The query MUST support for querying of all required attributes as per this national extension. The query MUST allow for, and gracefully handle, queries for all optional attributes defined in this national extension, or base IHE HPD.
   • Attributes of particular focus include: contact information, address, Direct Project / secure email address, SOAP service endpoints, FHIR resources, language, specialty, and x.509 certificate.
   • Eric note: How is this different, if at all, from the next query?
2. Find a list of individual providers that match a demographic.
   • The demographic will be based on the HPD data model and required attributes. Based on the above, that needs to be (at least) address, specialty, and language.
3. Find information on an organizational provider.
   • The information may largely be the same as an individual.
4. Find a list of organizational providers that match a demographic.
   • Information may be largely the same as an individual.
   • Eric note: How is this different than finding an organizational provider?
5. Find all individual providers affiliated with an organization.
   • I’ve heard people voice a need for this query, but I’m not sure I know the user story that goes with it. Is there one?
6. Find electronic service information for an individual associated with an organization.
   • This is supported, but it is not clear to me that it is outlined in the use cases above. We may want to be explicit about this use case: “Dr. Smith’s Direct address at Community Hospital rather than Dr. Smith’s Direct address at Smith Private Practice”.
7. Find the organization, or organizations, associated with an individual or organization.
   • Depending upon how we enable organizational service endpoints, it may be necessary to walk the hierarchy. For example, if I want the XCA query endpoint for Dr. Smith, I may need to look up the XCA query endpoint for the hospital Dr. Smith is affiliated with. If I want to look up the XCA query endpoint for an ED, I may need to look up the XCA endpoint at hospital housing the ED. Think of it as “given an individual, what is the parent organization?” and “given an organization, what is the parent organization?”.
