Clinical Informatics Certification Health Information Exchange 2 — Questions and Answers
Question 1: Which protocol enables secure 'push'-based exchange of health information, functioning similarly to encrypted email between known recipients?
- CommonWell Health Alliance
- FHIR REST API
- DIRECT Protocol (Correct answer)
- IHE XDS.b
Correct answer: DIRECT Protocol
The DIRECT Protocol provides a standards-based way to send encrypted health information directly to known recipients, similar to secure email, supporting care transitions and referrals.
Question 2: What does FHIR stand for in the context of health information exchange?
- Federal Health Information Repository
- Fast Healthcare Interoperability Resources (Correct answer)
- Federated Health Information Registry
- Functional Health Interoperability Reference
Correct answer: Fast Healthcare Interoperability Resources
FHIR (Fast Healthcare Interoperability Resources) is an HL7 standard designed to enable easy exchange of healthcare information using modern web technologies and APIs.
Question 3: Which implementation guide consolidates multiple CDA-based document templates into a single standard required for Meaningful Use transitions of care?
- HL7 v3 Reference Information Model
- Continuity of Care Record (CCR)
- Consolidated CDA (C-CDA) (Correct answer)
- FHIR DocumentReference
Correct answer: Consolidated CDA (C-CDA)
The Consolidated CDA (C-CDA) was developed to harmonize various CDA implementation guides into a single standard, simplifying document exchange for Meaningful Use and HIE.
Question 4: What is the primary technical advantage of FHIR APIs over older HL7 v2 and CDA standards for HIE?
- FHIR provides stronger encryption than HL7 v2
- FHIR uses RESTful APIs and JSON/XML, enabling easier integration with modern applications (Correct answer)
- FHIR eliminates the need for patient consent in data exchange
- FHIR stores data centrally for all participants
Correct answer: FHIR uses RESTful APIs and JSON/XML, enabling easier integration with modern applications
FHIR's use of RESTful APIs and common web formats like JSON and XML makes it significantly easier to integrate with modern applications and mobile devices compared to legacy HL7 standards.
Question 5: What type of organization is IHE (Integrating the Healthcare Enterprise), which develops profiles used in HIE implementations?
- A voluntary multi-stakeholder initiative of healthcare and IT professionals (Correct answer)
- A federal government regulatory agency
- A for-profit EHR certification company
- A subsidiary of the American Medical Association
Correct answer: A voluntary multi-stakeholder initiative of healthcare and IT professionals
IHE is a voluntary initiative by healthcare professionals and industry that publishes integration profiles addressing specific clinical needs through established standards like HL7 and DICOM.
Question 6: Which FHIR resource represents a structured set of healthcare information equivalent to a clinical document, serving as the foundation for clinical summaries?
- Patient Resource
- Composition Resource (Correct answer)
- Bundle Resource
- Observation Resource
Correct answer: Composition Resource
The FHIR Composition resource represents a structured set of healthcare information analogous to a CDA clinical document, organizing multiple data elements into a coherent summary.
Question 7: What is the primary purpose of the Trusted Exchange Framework and Common Agreement (TEFCA)?
- To standardize EHR pricing across the United States
- To establish a single on-ramp for nationwide health information exchange through common legal and technical requirements (Correct answer)
- To replace all state-level HIEs with a federal system
- To mandate that all providers join a specific HIE network
Correct answer: To establish a single on-ramp for nationwide health information exchange through common legal and technical requirements
TEFCA, developed by ONC, creates a common set of legal and technical requirements enabling different health information networks to exchange data seamlessly across the country.
