EHR Interoperability & Health Information Exchange 5 — Questions and Answers
Question 1: Which SMART on FHIR component allows a third-party application to request access to a specific subset of a patient's EHR data?
- OAuth 2.0 scopes (Correct answer)
- SAML assertions
- X.509 certificates
- LDAP directory
Correct answer: OAuth 2.0 scopes
SMART on FHIR uses OAuth 2.0 scopes to define the precise data types and permissions an application is requesting on behalf of a user.
Question 2: What does 'data provenance' mean in health information exchange, and why is it important?
- Tracking the origin and history of health data to ensure its trustworthiness (Correct answer)
- Encrypting data during transport

- Converting data to a standard format
Correct answer: Tracking the origin and history of health data to ensure its trustworthiness
Provenance records who created data, when, and from where, helping clinicians assess the reliability of received information.
Question 3: Which challenge is most commonly associated with patient matching across different healthcare organizations in an HIE?
- Duplicate and mismatched patient records due to inconsistent demographic data entry (Correct answer)
- Slow network speeds
- Lack of clinical content in exchanged documents
- Insufficient storage capacity
Correct answer: Duplicate and mismatched patient records due to inconsistent demographic data entry
Inconsistent data entry (misspellings, nicknames, address variations) leads to false negatives and positives in patient matching algorithms.
Question 4: Under the ONC information blocking rule, which of the following is a legitimate exception that permits withholding patient data?
- Preventing harm to the patient or another person (Correct answer)

- To store patient records permanently
- To adjudicate insurance claims
- To certify EHR software
Correct answer: To manage security certificates and route Direct messages between senders and receivers
A HISP provides the infrastructure and certificate management needed to send and receive Direct messages securely.

- Support Electronic Referral Loops by Sending Health Information measure (Correct answer)
- Provide Patients Electronic Access to Their Health Information measure
- Health Information Exchange measure
- Immunization Registry Reporting measure
Correct answer: Support Electronic Referral Loops by Sending Health Information measure
This PI measure tracks the percentage of transitions where an electronic summary of care record is sent to the receiving provider.
