HAC Health Information Exchange & Interoperability 3

Question 1

A healthcare analytics team wants to query patient records on demand from multiple EHRs without a central repository. Which HIE model best fits this approach?

Accepted Answer

Federated HIE

Answer

A federated HIE leaves data at source systems and enables queries across them in real time, without centralizing patient records.

Question 2

Under the HIPAA Privacy Rule, which of the following is a permitted use of PHI without patient authorization for HIE purposes?

Accepted Answer

Treatment, payment, and healthcare operations (TPO)

Answer

HIPAA permits disclosure of PHI without authorization for treatment, payment, and healthcare operations activities, which are foundational to HIE.

Question 3

What is the role of a Record Locator Service (RLS) in a federated HIE?

Accepted Answer

Identifying which participating organizations hold data for a given patient

Answer

An RLS maintains a directory of which network participants have records for specific patients, enabling targeted queries without a central data store.

Question 4

Which FHIR capability allows a client system to subscribe and receive automatic notifications when patient data changes?

Accepted Answer

FHIR Subscription resource

Answer

The FHIR Subscription resource enables server-driven notifications to clients when specific resources matching defined criteria are created or updated.

Question 5

Semantic interoperability in health data exchange is primarily achieved through:

Accepted Answer

Common clinical terminologies such as SNOMED CT and LOINC

Answer

Semantic interoperability requires that systems share a common understanding of the meaning of data, achieved through standardized terminologies and ontologies.
