What is HL7?Founded in 1987, Health Level Seven International (HL7) is a not-for-profit, ANSI-accredited standards developing organization dedicated to providing a comprehensive framework and related standards for the exchange, integration, sharing, and retrieval of electronic health information that supports clinical practice and the management, delivery and evaluation of health services.

What is HL7 FHIR?FastHealthcareInteroperabilityResources
Research on FHIR: Protocol
• FHIR is a new specification based on emerging industry approaches, but informed by years of lessons around requirements, successes and challenges gained through defining and implementing HL7 v2, HL7 v3 and the RIM, and CDA.

What is HL7 FHIR®?FastHealthcareInteroperabilityResources
Research on FHIR: Protocol
• Core focus on Healthcare• Healthcare and Research differ in their
approaches– What is captured– How it is captured– How it is reported
• Healthcare data is Research data and Research data is Healthcare data
![Page 6: Protocolson FHIR –exchanging study designs with EHR systems](https://reader031.vdocument.in/reader031/viewer/2022022807/621b31760934b57a0523d804/html5/thumbnails/6.jpg)
What is HL7 FHIR®?FastHealthcareInteroperabilityResources
Research on FHIR: Protocol
• Intended for exchange• No assumptions about how the data is
maintained internally• Uses common standards for exchange
(REST)• Searchable• Versioned• Pathways to and from FHIR to CDA,
OMOP and SDTM

What is HL7 FHIR®?FastHealthcareInteroperabilityResources
Research on FHIR: Protocol
• A set of extensible well-defined, generic representational artifacts for healthcare data (Base Resources)
• System independent• Clear semantics• Links, references, external value lists• Resources have lifecycle management
through stability designations; from 0 through to Normative

What has been done?
Research on FHIR: Protocol
Mapping• CDISC EHR to CDASH• FHIR to CDISC Joint Mapping
Implementation Guide (BR&R)

How will the SoA on FHIR help?• Better data integration experience
• Better cost tracking
• Reusing integrated systems
Research on FHIR: Protocol
• Observations that pertain to research activities are linked
• Activities explicitly linked to trial protocols as well as invoicing systems
• EHR Systems have integrations that can be utilized– Patient Calendar (e.g. Epic MyCharts)– Workflow management systems– Facilities management systems
![Page 11: Protocolson FHIR –exchanging study designs with EHR systems](https://reader031.vdocument.in/reader031/viewer/2022022807/621b31760934b57a0523d804/html5/thumbnails/11.jpg)
How will the SoA on FHIR help?• Integrated process tracking
• Discoverability
• Provenance/Traceability
Research on FHIR: Protocol
• Query the EHR for status of activities
• Deployed SoA can be found directly within the EHR
• Patient load can be inferred directly
• Relationships between Resources and Attributes are traceable
![Page 12: Protocolson FHIR –exchanging study designs with EHR systems](https://reader031.vdocument.in/reader031/viewer/2022022807/621b31760934b57a0523d804/html5/thumbnails/12.jpg)
What can be done with the Schedule of Activities (SoA)?• The SoA is a key part of the Protocol• It describes what happens and when
Research on FHIR: Protocol
Planned Activities
Encounters
• It doesn't specify "how" – activities take place and observations are recorded.

FHIR Resources for SoA Specification
ResearchStudy PlanDefinition ActivityDefinition
Specifies a study'sdetails as definedin the protocol
(such as title, phase, condition,principal investigator, armetc.)
Details pre-defined groups of actions
(such as those required by a study as presented in the SoA)
Describes an activity or task
(to be undertaken as part of the study data collection, e.g. collect vital signs)

Outcomes for the Project• Using the CDISC Pilot Project (Eli-Lilly H2Q-MC-LZZT) as a ‘digital twin’
– Have ODM, Protocol, CSR, Data assets• Build out the SOA in a systematic way
– Sample ResearchStudy– Schedule of Planned Visits– Schedule of Planned Visits plus one Activity– Schedule of Planned Visits with repeated Activities– Schedule of Planned Visits with multiple Activities– Full SoA for the H2Q-MC-LZZT
• Publication of FHIR Bundles for each checkpoint so anyone can pick it up and run with it.
• Development of an Implementation Guide for Schedules of Activities

FHIR ® Implementation Guides• A set of rules of how a particular interoperability or standards problem is solved -
typically through the use of FHIR resources. This resource is used to gather all the parts of an implementation guide into a logical whole and to publish a computable definition of all the parts.
• Example Scenarios– Do we need new Resources for the SOA Use case?
• StudyArm as a derivative of a Group– Do we need to extend/specialise existing resourses?
• StudyVisitDefinition as an extension of PlanDefinition to include study specific attributes such as Planned Study Day, Study Day Window
• Published as part of the HL7 FHIR® build process
