1. Provider Directories - Technical Activities Update Nagesh Bashyam 1/16/2014

2. Background Which standard should a vendor implement ? – IHE HPD or IHE HPD with CP 601 – HPDPlus v1.0 or v1.1 – ModSpec Provider Directory (Federated HPD?) IHEEHR|HIE IWGONC IHE Healthcare Provider Directory Profile published for trial implementation in August 2010. S&I Provider Directory Initiative completed HPD Plus v1.0 completed IHE HPD CP 601 added to IHE HPD HPDPlus v1.1 reconciled with IHE CP 601ONC Mod Spec Provider Directory (Federated HPD) completed

3. Comparison of Standards Data Model – IHE HPD is the data model based on ISO 21091 – HPD Plus v1.0, v1.1 and IHE HPD CP 601 try to add the data elements identified by S&I Provider Directory Initiative (ESI) – Federated HPD (ModSpec PD) uses the same data model as HPDPlus Web Interface (WSDL) – WSDL is similar and compatible between IHE HPD and HPD Plus versions – Federated HPD WSDL is slightly different from the base WSDL and hence is not backward compatible

4. NYeC Pilots ONC Exemplar HIE Governance program awarded NYeC project to conduct Provider Directory pilots examining federation and implementation challenges in the PD space Environment scan and Actual pilots identified – PD Implementations are just starting, none of the existing standards is widely implemented – Implementations differ from each other in terms of standards and technologies Pilots – Snowbird Pilot – California Pilot – NATE Pilot – NY Pilot Feedback – Confusion about standards (Need a single standard to implement!!) – When the same standards were used the same value sets were not being used consistently (Need complete definition of value sets that are applicable) – Needed ONC ModSpec activity to be adopted by IHE – Most federated solutions are one-off and not adopting a standard – Complex queries are cumbersome in the existing standards

5. ONC/IHE Harmonization Activities ONC Presented Federated HPD to IHE ITI Planning Committee in Fall 2013 IHE approved a project to bring Federated HPD under IHE umbrella but as a US specific profile ONC working with IHE to create the Federated HPD as a US specific profile – Had public calls with community and implementers – After long discussions, the community is going forward with the Federated HPD work as it currently exists to solicit feedback – IHE New Directions Connectathon established for end of January to test Federated HPD and gather technical feedback – Participants will get an opportunity to showcase the test results at HIMSS New Directions Showcase.

6. Test Tools ONC publishing the PD Sandbox on SITE – http://sitenv.org http://sitenv.org – Forum to ask questions – Test Tool to help implementers test their Provider Information Directory Provider Information Consumer Provide a federation partner as necessary
