CAHIMS Health Information Exchange and Interoperability 1 — Questions and Answers
Question 1: Which federal legislation established the framework for a nationwide Health Information Exchange (HIE) network in the United States?
- HIPAA
- HITECH Act (Correct answer)
- ACA
- MACRA
Correct answer: HITECH Act
The HITECH Act (Health Information Technology for Economic and Clinical Health Act) of 2009 established the framework for a nationwide HIE infrastructure and incentivized EHR adoption.
Question 2: What does the term 'interoperability' mean in the context of health information systems?
- The ability to back up data across multiple servers
- The capacity of different systems to exchange and use shared information seamlessly (Correct answer)
- The encryption of data during transmission
- The process of auditing user access to health records
Correct answer: The capacity of different systems to exchange and use shared information seamlessly
Interoperability refers to the ability of different health information systems and software to communicate, exchange data, and use the exchanged data effectively.
Question 3: Which of the following best describes a Federated Health Information Exchange (HIE) model?
- All patient data is stored in a single central repository
- Data remains at the source organization and is accessed on demand (Correct answer)
- Data is replicated to all participating organizations nightly
- A third-party vendor stores and manages all participant data
Correct answer: Data remains at the source organization and is accessed on demand
In a federated HIE model, data stays at the originating organization and is queried directly when needed, rather than being stored in a central database.
Question 4: HL7 FHIR is best described as:
- A federal privacy regulation for health data
- A standard for electronic health record billing codes
- A modern interoperability standard using web-based APIs for health data exchange (Correct answer)
- A hardware specification for medical device connectivity
Correct answer: A modern interoperability standard using web-based APIs for health data exchange
HL7 FHIR (Fast Healthcare Interoperability Resources) is a modern standard developed by Health Level Seven International that uses RESTful APIs and web technologies to enable health data exchange.
Question 5: A Master Patient Index (MPI) in an HIE is primarily used to:
- Encrypt patient data during transmission between facilities
- Uniquely identify patients across multiple healthcare organizations (Correct answer)
- Store clinical decision support rules for providers
- Track insurance eligibility in real time
Correct answer: Uniquely identify patients across multiple healthcare organizations
A Master Patient Index (MPI) maintains a unique identifier for each patient across multiple systems or organizations, enabling accurate patient matching in an HIE.
Question 6: Which type of HIE architecture stores a copy of patient data in a centralized repository accessible to all participants?
- Federated model
- Hybrid model
- Consolidated model (Correct answer)
- Decentralized model
Correct answer: Consolidated model
The consolidated (or centralized) HIE model stores copies of patient data in a shared central repository that all participating organizations can query.
Question 7: The ONC (Office of the National Coordinator for Health Information Technology) 21st Century Cures Act rules primarily aim to:
- Mandate specific EHR vendors for all hospitals
- Prohibit information blocking and promote patient access to health data (Correct answer)
- Eliminate the use of paper records by 2025
- Require all providers to use FHIR by 2020
Correct answer: Prohibit information blocking and promote patient access to health data
The ONC 21st Century Cures Act rules prohibit information blocking and require certified health IT to support open APIs so patients and providers can freely access health information.
