CHI CHI Interoperability & Health Information Exchange 2 — Questions and Answers
Question 1: Which HL7 standard was specifically designed to support the exchange of structured clinical documents such as discharge summaries?
- HL7 v2.x ADT messages
- HL7 CDA (Clinical Document Architecture) (Correct answer)
- HL7 v3 RIM only
- HL7 FHIR Observation resource
Correct answer: HL7 CDA (Clinical Document Architecture)
HL7 CDA (Clinical Document Architecture) is an XML-based standard for exchanging structured clinical documents like discharge summaries and CCDs.
Question 2: What is the primary purpose of the Consolidated CDA (C-CDA) templates in health information exchange?
- To encrypt patient data during transmission
- To provide standardized document templates ensuring consistent clinical content (Correct answer)
- To replace ICD-10 codes with SNOMED codes
- To automate billing claim submissions
Correct answer: To provide standardized document templates ensuring consistent clinical content
C-CDA templates define standardized document structures (e.g., Continuity of Care Document) to ensure consistent, interoperable clinical content.
Question 3: Under the ONC's Trusted Exchange Framework and Common Agreement (TEFCA), Qualified Health Information Networks (QHINs) are required to:
- Replace all state HIEs
- Enable nationwide health information exchange under a common set of rules (Correct answer)
- Exclusively serve Medicare beneficiaries
- Operate only in federally designated rural areas
Correct answer: Enable nationwide health information exchange under a common set of rules
TEFCA establishes a universal policy and technical framework through QHINs to enable nationwide, trusted health information exchange.
Question 4: Which data standard provides a common vocabulary for laboratory results, enabling consistent exchange between labs and clinical systems?
- CPT-4
- LOINC (Correct answer)
- ICD-10-PCS
- NDC
Correct answer: LOINC
LOINC (Logical Observation Identifiers Names and Codes) provides universal codes for identifying laboratory and clinical observations.
Question 5: An EHR that can send and receive data with other EHRs but cannot use the received data in clinical workflows has achieved which level of interoperability?
- Functional interoperability
- Semantic interoperability
- Technical (foundational) interoperability (Correct answer)
- Organizational interoperability
Correct answer: Technical (foundational) interoperability
Technical/foundational interoperability means data can be transmitted and received, but meaningful use of the data requires higher interoperability levels.
Question 6: What does 'data provenance' refer to in health information exchange?
- The geographic origin of a patient's diagnosis
- The documented history of where data came from and how it was modified (Correct answer)
- The process of deleting outdated patient records
- A type of audit for billing compliance
Correct answer: The documented history of where data came from and how it was modified
Data provenance tracks the origin, custody, and transformation history of data to support trust and traceability in health information exchange.
