  • 2. Agenda Topics What is Interoperability? How interoperable are current health IT systems? Key Health IT Interoperability Challenges Benefits of Increasing Health IT Interoperability Strategies for Improving Health IT Architecture Interoperability Break Out Groups Report Out from Break out groups Improving Interoperability through Effective Health IT Architectures 2
  • 3. What is Health IT Interoperability?
  • 4. How do we define interoperability? Improving Interoperability through Effective Health IT Architectures 4
  • 5. What is Interoperability? Interoperability generally refers to "the ability of two or more systems or components to communicate, to exchange data accurately, effectively, and consistently and to use the information that has been exchanged….” “In healthcare, the ability ‘to use the information that has been exchanged’ means not only that healthcare systems must be able to communicate with one another, but also that they must employ shared terminology and definitions.” Source: HL7 Coming to Terms Whitepaper Improving Interoperability through Effective Health IT Architectures 5
  • 6. How interoperable are current Health IT systems? Do all health IT systems store the same information, the same way (e.g. demographics)? Can patients move between providers/doctors and with their health history accessible? How do Health IT systems exchange data today? Do we have a common language that all business partners health IT systems speak? Interoperability between clinical and public health systems? How is security and privacy of consumers and protected health information managed across health IT systems? … Improving Interoperability through Effective Health IT Architectures 6
  • 7. Why is Health IT Interoperability important? Make improved health decisions based on all data Improve exchange of health information between health IT systems Access information across different systems, sectors, platforms Reduce cost and complexity Enable future ready solutions Continuity of care for patients Improving public health situational awareness Improving Interoperability through Effective Health IT Architectures 7
  • 8. What are real-life examples of good interoperability? Lets look the phone as an example What makes phones interoperable? Is it what material phone is made from? Is it the features, ringer, dial pad? Is it the shape, color? Calling parties have to be in the same geographic area? Is it the manufacturer? Improving Interoperability through Effective Health IT Architectures 8
  • 9. Key Health IT Interoperability Challenges HIT is a extremely fast moving train with brand new concepts, architectures, needs, etc. Nature of “Enterprise” is changing – Clinical and PH and … Interoperability is complex and not well understood Difficult to coordinate across systems and organizations What do we want to make interoperable? What is the scope of interoperablity? Siloed health it systems in different groups and programs Data elements are not common across same type of Health IT systems Coordinating security and privacy of health IT systems Lack of coordinated standards in use by all HIE players Document based vs messaging based architecture choices Strategic architectural understanding and approach Cross HIT governance is a challenge Funding Improving Interoperability through Effective Health IT Architectures 9
  • 10. Strategies for Improving Health IT Architecture Interoperability
  • 11. Interoperability Guiding Principles Adopt and leverage national HIT Architectures Adopt and leverage national HIT standards Reusable Shared Services based on Services Oriented Architecture (SOA) design principles Architect/Design with interoperability as a key requirement from start Create technology neutral architecture Stronger governance of Health IT across health organization “Enterprise Architect” role, to focus on common enterprise issues Improving Interoperability through Effective Health IT Architectures 11
  • 12. Levels of Health IT Interoperability Different levels of Health IT Interoperability 1. Not interoperable 2. Within same health organization 3. Regional HIE 4. Statewide HIE 5. National HIE 6. International Improving Interoperability through Effective Health IT Architectures 12
  • 13. Public Health IT Systems Interoperability Typical PH IT Systems Immunization Disease Surveillance Vital Records Lab Systems Registries (Cancer, STD, TB, ) Environmental Health, Lead, … There are number of common functions across health systems Are PH IT Systems integrated with other Health systems? How to improve interoperability of the PH IT systems? Improving Interoperability through Effective Health IT Architectures 13
  • 14. HIT Use Cases example Improving Interoperability through Effective Health IT Architectures 14
  • 15. Nationwide Health Information Network Highly distributed: Patient health information is retained at the local health information exchange level Local autonomy: Each HIE must make their own determinations with respect to the release of patient information Focus only on inter- organizational health exchange: The NHIN does not attempt to standardize implementations of the NHIN services and interfaces, only the communications between HIEs Use public internet: The NHIN is not a separate physical network, but a set of protocols and standards that run on the existing internet infrastructure Platform neutral: The NHIN has adopted a stack (web services) that can be implemented using many operating systems and programming languages 15 Copyright 2009.

  • 16. HIT Standards for Interoperability Enterprise Health IT Architecture leverages HIT Standards for number of reasons including Creating a reusable architecture Improve standardization Increase future adaptability Improve integration across HIT systems … Momentum and progress on HIT standards has increased substantially What are the “right” standards for what purpose?

  • 20. Reusable Shared Services in Health IT (using SOA) Why do we have so many separate or silo systems? And there are common functions/services in many of systems Lets change the paradigm of building new health systems to reusing shared services Challenges: What reusable services are needed for Health Information Exchanges? How can Service Oriented Architecture principles be applied throughout the Enterprise Architecture? Improving Interoperability through Effective Health IT Architectures 20
  • 21. Reusable Shared Services in Health IT (using SOA) Here is a starting list of potential HIE reusable services… HIE Immunization PH Case Get Enrollment Validation Reusable Reporting Health Records Shared Demographic Services Service Patient Authentication Matching Eligibility Secure Check Personal Health Get Immunization Allergy Messaging Record Update Records Check What other Shared Services are needed? Improving Interoperability through Effective Health IT Architectures 21
  • 22. Privacy and Security Support national privacy & security standards. Create standards by which data can be shared and adopt one set of clearly defined privacy standards. Implement standardized measures to safeguard protected health information (PHI). Security & Access Control Authentication Identity Management Transport Privacy HL7 v3 RBAC Kerberos Network Auth v5 LDAP XDS.b SAML EUA End User Authentication Personal White Pages WS-Trust v1.7 WS- Security OASIS XACML (2015) Challenges: How many states have common Directory/LDAP that apps use?
