What is the purpose of role-based access control (RBAC) in an EHR system?
Answer: Grant system access permissions based on a user's job function rather than individual identity
RBAC restricts EHR access by assigning permissions based on defined job roles, ensuring users can only access the information necessary to perform their duties.
In healthcare analytics, what is the difference between a data warehouse and a transactional database?
Answer: A data warehouse integrates historical data from multiple sources for analysis; a transactional database supports day-to-day operations
A data warehouse aggregates historical, integrated data from multiple operational systems to support complex reporting and analysis, while transactional databases are optimized for real-time operational tasks.
What is the function of a PACS (Picture Archiving and Communication System) in healthcare?
Answer: Store, retrieve, and display medical images such as X-rays and MRIs digitally
PACS stores and manages digital medical images (X-rays, CT scans, MRIs) and allows radiologists and clinicians to access them electronically from any authorized workstation.
Which federal certification program evaluates whether EHR technology meets standards for meaningful use and interoperability?
Answer: ONC Health IT Certification Program
The ONC (Office of the National Coordinator for Health Information Technology) Health IT Certification Program certifies that EHR products meet federal standards for functionality and interoperability.
What is the primary goal of a health information system implementation project's go-live phase?
Answer: Transition from the old system to the new system in the live production environment
The go-live phase is when the new system transitions from a test/training environment to the live production environment where it handles real patient data and operations.
In health informatics, what does the acronym LOINC stand for?
Answer: Logical Observation Identifiers Names and Codes
LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations in health records and exchanges.
