EHR Interoperability & Health Information Exchange 2 — Questions and Answers
Question 1: Which HL7 FHIR resource is used to represent a patient's allergy or intolerance information when exchanging data between systems?
- AllergyIntolerance (Correct answer)
- Condition
- Observation
- MedicationStatement
Correct answer: AllergyIntolerance
The HL7 FHIR AllergyIntolerance resource is specifically designed to capture and exchange allergy and intolerance data.
Question 2: What does the term 'semantic interoperability' mean in the context of health information exchange?
- Systems can exchange data and accurately interpret its meaning (Correct answer)
- Systems use the same network protocols
- Data is encrypted during transmission
- Systems share the same user interface
Correct answer: Systems can exchange data and accurately interpret its meaning
Semantic interoperability ensures that exchanged data is interpreted consistently and accurately across different systems.
Question 3: A hospital receives a C-CDA document from a referring physician. Which section would contain the patient's current medication list?
- Medications Section (Correct answer)
- Problems Section
- Results Section
- Plan of Treatment Section
Correct answer: Medications Section
The Medications Section in a C-CDA document is the designated location for listing a patient's current medications.
Question 4: Which query-based exchange model allows a provider to search for and retrieve patient records from multiple sources without prior knowledge of where data is stored?
- Query-based exchange via an HIE (Correct answer)
- Push-based direct messaging
- Centralized data repository
- Point-to-point interface
Correct answer: Query-based exchange via an HIE
Query-based exchange through an HIE enables providers to search across multiple repositories to find patient data on demand.
Question 5: What is the primary role of a Master Patient Index (MPI) in health information exchange?
- To uniquely identify patients across multiple healthcare organizations (Correct answer)
- To store clinical documents centrally
- To manage physician credentials
- To process insurance claims
Correct answer: To uniquely identify patients across multiple healthcare organizations
An MPI assigns and manages unique patient identifiers to correctly match patient records across different facilities.
Question 6: Which federal program requires eligible professionals and hospitals to demonstrate meaningful use of EHRs, including health information exchange capabilities?
- Medicare and Medicaid EHR Incentive Programs (Correct answer)
- HIPAA Security Rule
- Stark Law
- Anti-Kickback Statute
Correct answer: Medicare and Medicaid EHR Incentive Programs
The Medicare and Medicaid EHR Incentive Programs (now the Promoting Interoperability Programs) incentivized meaningful use of certified EHR technology.
Question 7: When two EHR systems use different local codes for the same diagnosis, which approach resolves this semantic gap during data exchange?
- Mapping local codes to a standard terminology like ICD-10 or SNOMED CT (Correct answer)
- Converting all data to plain text
- Using a shared proprietary code set
- Sending only free-text descriptions
Correct answer: Mapping local codes to a standard terminology like ICD-10 or SNOMED CT
Mapping to standard terminologies ensures that both systems interpret the diagnosis consistently regardless of their internal coding.
