Direct Implementation Perspective 0 Mark Bamberg, Vice President Research & Development MEDfx

Overview Introduction Secure Content Delivery with DIRECT HIE Architecture Lab result delivery Heterogeneous Labs Multiplexed thru HIE Recommendations 1

Introduction - MEDfx 2 Committed member of ONC Standards and Interoperability Framework. Participating member of Transitions of Care Architecture Workgroup. Participating as Workgroup Lead for S&I Framework Transitions of Care Reference Implementation and Pilots Workgroup. Participating member of Direct Reference Implementation and Direct Implementation Geographies Workgroups. Completed Direct Project Pilot unveiled at the HIMSS 2011 ONC Interoperability Showcase with a live demonstration of NwHIN and Direct interoperability.

Introduction – MEDfx 3 Developed 1 st integration of an HIO to a government agency to provide CCD documents to SSA automating the disability determination process. Integrated the 2 nd Virtual Lifetime Electronic Record (VLER) community using the NwHIN to connect an HIO to the Veterans Administration (VA) and Department of Defense (DoD). ‘First to CMS via the NHIN’ as a participant in the C-HIEP project enhancing communication and coordination of care across multiple settings. Invited to demonstrate NwHIN integration to members of Congress as part of Health IT Week in Washington, D.C., September 2009.

Secure Content Delivery with Direct Lab Order Example 4 HIE/EHR HISP HIE/EHR HISP Lab HIE / EHR Backend HIE / EHR Portal/Client 1.EHR Portal/Client sends lab result query to EHR Backend or HIE via EDGE over secure channel 2.EHR Backend or HIE sends message to HISP using SMTPS on port HISP verifies Lab is trusted by verifying the Lab’s certificate can be located and has been digitally signed by a trusted authority (Root Anchor) 4.HISP uses Provider’s Private Key (to sign) and Lab’s Public key (encipher) to create a secure payload encode using S/MIME 5.HISP routes message via SMTP on port 25 to Lab’s HISP 6.Lab HISP verifies Provider is trusted by verifying the Provider’s certificate can be located and has been digitally signed by a trusted authority (Root Anchor) 7.Lab uses its Private key to decipher and Providers public key to verify message signature 8.HISP sends deciphered message to Lab backend 9.HISP sends receipt to Provider SMTP 1 SMTP 2 SMTP 3 LAB HISP LAB HISP

Recommendations Multiplex Lab Feeds thru HIE – Reduces complexity and cost of developing interfaces – Handles message routing – Automatic transport and content conversion – Ensures lab orders and results delivery Message failures are routed to remediation Utilize EHR Hub Solutions – When an EHR has a Hub solution, the EDGE appliance can connect to the EHR Hub for message routing 14
