AEGIS has been supporting Interoperability Testing within the HealthIT space with VA/HHS (ONC). HHS/ONC Nationwide Health Information Exchange (NwHIN) (IHE/HL7/OASIS-SAML) Healtheway Compliance Testing Body (CTB) Certification process for the eHealth Exchange OSEHRA Open Source Interoperability Work Group with a focus project of the DIL. NIST HITECH Award HITTI HL7 Conformance Testing Platform Introduction 3

AEGIS.net, Inc. - Powerful Results. Delivered. SM Definition of Interoperability (let’s agree to use IEEE). Participants and Systems Not Ready for Certification or Accreditation ◦ Dependence on Self-Attestation Understanding the Standards and Specifications ◦ Common (or Consensus based) Interpretation. Conformance vs Interoperability Syntactic vs Semantic Interoperability Interoperability vs Continuous Interoperability Challenges facing Standards Adoption 4
5
AEGIS.net, Inc. - Powerful Results. Delivered. SM Topic: Open Source Development Objective: Adherence to a Standard can be demonstrated thru implementation & testing State of Maturity HealthIT Standards 5
6
Why Interoperability is Challenging Systems Interoperability Challenges o Organizational exchange of information o Interruption thru Implementation o Common Testing Approach (Happy Path) o Limited Exception Negative Testing (due to dependence on Peer-to-Peer testing) o Change (yes, there will be change) Standards will be put under new intense pressure. 6 AEGIS.net, Inc. - Powerful Results. Delivered. SM

Robustness Principle "Be conservative in what you send, be liberal in what you accept" http://en.wikipedia.org/wiki/Robustness_principle Conservative – Happy Path Liberal – Negative and Exception Path 7 AEGIS.net, Inc. - Powerful Results. Delivered. SM
8
How to Mitigate Interoperability Risk We offer a way to Mitigate Interoperability Risk o Because – you will face Interoperability Issues Interoperability Strategies o Standards based Testing (feedback loop) o Test Early and Test Often o Infuse Interoperability into the Development Cycles thru TDD (Test Driven Development) o Embrace the goal of Continuous Interoperability thru process 8 AEGIS.net, Inc. - Powerful Results.

Standards view thru Statistics 2013 - 1,387 Implemented Test Cases*: 522 Conformance Rules applying over 36,000 checkpoints. Over 77,391 Test Case Executions starting in April 2013 ◦ By Healtheway's CTB candidate participants and vendors.

DIL Statistics More than 200+ Organizations Registered on the DIL to test 45 active Healtheway 2014 onboarding candidates (through Sept.) Healtheway 2013 Onboarding Candidates Product Vendors8 HIE Participants34 Federal Agencies3 Key Findings: 1. Neither vendors or participants are ready when they started certification testing. 2. 2-4+ month learning curve to demonstrate compliance to baseline specifications and required message conformance/interoperability expectations. 13 AEGIS.net, Inc. - Powerful Results. Delivered. SM
14
The DIL provides objective analysis of health information standards implementation and exchange problem areas: DIL Statistics DIL execution data record the root cause(s) of conformance/interoperability failures: System/product failures Test case definition defect Specification lacks sufficient implementation guidance 14

Industry Approach to Interoperability ONC Roadmap to Interoperability (10 Years) Patient Privacy (Consent Policy & DS4P) o Unstructured vs Structured Data o Granularity o Data Providence Leverage Existing HIT Infrastructure FDASIA Report (Risk Management) Jason Report (API Architecture) 15 AEGIS.net, Inc. - Powerful Results.

AEGIS.net, Inc. - Powerful Results. Delivered. SM HIE participant learning curves vary widely. One example: DIL Statistics 18 Early failures -> Learning - > Refinement -> Success
19
AEGIS.net, Inc. - Powerful Results. Delivered. SM HIE participant learning curves vary widely. BEST CASE: DIL Statistics 19 2 calendar months from DIL registration to CTB test case results submission for CCHIT review/Healtheway CC onboarding approval.
20
AEGIS.net, Inc. - Powerful Results. Delivered. SM Once past the system configuration learning curve, DIL Test Execution is FAST: DIL Statistics 20 12 MINUTES to actually execute the test cases required for Healtheway’s 2013 onboarding program.
21
AEGIS.net, Inc. - Powerful Results. Delivered. SM Product Vendor learning curve example: DIL Statistics 21 Early failures -> Learning - > Refinement -> Success Vendors should take more time—and make use of the DIL more extensively—than individual participants.
