Transforming Healthcare Standards with FHIR: Simplicity and Collaboration in Healthcare

Healthcare standards have long been complex, costly, and difficult to implement. However, the Fast Healthcare Interoperability Resources (FHIR) initiative is changing that paradigm. Pronounced "Fire," FHIR is based on industry best practices and prioritizes simplicity, implementability, and collaboration among stakeholders. It introduces standardized, web-based resources that are easily accessible and can be structured in common formats like XML or JSON. With a built-in framework for extensibility, FHIR enables more efficient data exchange, supports innovation in healthcare technology, and fosters an enthusiastic community for seamless interoperability.

Presentation Transcript

  1. More Than You Think HL7 is people, HL7 is ideas, HL7 is collaboration

  2. Healthcare Standards • Complex…. Slow… • Hard to use and understand • Require specialist skills, tools • Costly

  3. Healthcare Standards • Complex…. Slow… • Hard to use and understand • Require specialist skills, tools • Costly What if it didn’t have to be like that?

  4. Introducing FHIR • Fast Health Interoperability Resources • Pronounced “Fire” • Based on industry best practices, with a focus on simplicity and implementability …insert your fire related joke here….

  5. Resources Resources are: • “Things” that live on the web • Read/updated etc via HTTP • Known content and meaning • Identity (= location) – can be moved • Represented in XML or JSON (or others) • Molecules to build useful systems

  6. Extension with reference to its definition Human Readable Summary • Standard Data Content: • MRN • Name • Gender • Date of Birth • Provider

  7. Resources have 3 parts • Defined Structured Data • The logical, common contents of the resource • Mapped to formal definitions/RIM & other formats • Extensions • Local requirements, but everyone can use • Published and managed • Narrative • Human readable (fall back)

  8. Kinds of Resources • Administrative Concepts • Person, Patient, Organization, Device, Facility • Coverage, Invoice, etc. • Clinical Concepts • Allergy, Problem, Medication, Family History • Care Plan • Infrastructure Functionality • Document, Message, Conformance/Profiling

  9. Using Resources • Classic Web RESTfulapproach • Simple approach led by Facebook, Twitter, etc. • Bundles – use Atom to group them • Internet syndication (publish/subscribe) • Messages (~v2), Documents (~CDA) • Custom Services (SOA) • Same content / base rules • Portability

  10. FHIR Ethos • Simplicity / Web alignment • Implementation focused • Reference Implementations (C#, Java, etc) • Publically available test servers (now) • Connectathons • Freely available • http://hl7.org/fhir • Unencumbered – free for anyone to use

  11. License

  12. Extensions • Managing extensibility is a central problem • Everyone needs extensions, everyone hates them • FHIR tames extensibility • Built in extensibility framework (engineering level) • Define, publish, find extensions • Use them • This tames the overall specification

  13. Progress • Extensive SDO consultation • Enthusiastic Community Adoption • Geometric Growth in Connectathons • Recognition at HITSC & other national programs • Candidate and Prototype programs • Data Collection / Specification • Exchange & Integration, Analysis

  14. Collaborations Harvard Clinical Genomics resources: • Sequences / Diagnostics • Genome Expression / Analysis Progress: • Draft Resources • Prototype Implementation for exchange

  15. Future Plans • Internal preparation phase • Very solid infrastructure (implementation focus) • More work required still • September ballot cycle – DSTU • DSTU = Draft Standard for Trial Use • Publish FHIR as full DSTU end 2013

  16. Follow Up • Read the spec: http://hl7.org/fhir • Follow #FHIR on Twitter • Shape the specification: • Make comments online • Join the FHIR email list http://wiki.hl7.org/index.php?title=FHIR_email_list_subscription_instructions • Try implementing it • Come to the Connectathon! • Come to the next meeting (San Antonio in Jan)
