In 2012, the HIT Standards Committee evaluated the provider directory standards suggested for the Nationwide Health Information Network and concluded that none of the current implementation guides was sufficiently mature and adopted to mandate as a certification criteria for Meaningful Use Stage 2.
This means that vendors and HIEs will continue to pilot various approaches to provider directories until Stage 3.
In Massachusetts, we chose a simple web-friendly implementation that goes live across the Commonwealth in two weeks.
We created a SOAP 1.2-based API that enables any trusted partner to query the state-wide provider directory via HTTPS per this specification.
The provider search web service provides following parameters to search a provider.
but requires one of the elements in the list below in order to perform a successful search.
With a simple SOAP query response approach and a WSDL, we have everything we need - no complicated implementation guide or non-standard use of LDAP/DNS required.
If this works well in production, it could be a model for the country.
How will we load the provider directory?
Each organization will be registered via an identity proofing process that ensures we have a fabric of trusted entities which have signed participant agreements.
As part of the registration process, the organizations will pre-load their provider data into the state directory using this spreadsheet.
Ongoing updates (adds/deletes/changes) can be sent via the same template.
Once in production, I'm sure we will refine our approach, but creating a simple SOAP-based query/response and a template for loading/updating data in batch seems to solve the Provider Directory standards gap nicely.
