Which HIPAA rule specifically establishes national standards for the protection of individually identifiable health information?

In EHR systems, what does an audit trail primarily provide?

An audit trail logs all user actions within a system, providing accountability and supporting investigations of unauthorized access.
A hospital uses a system where patient demographic updates made in the registration system are automatically reflected in all connected clinical systems. What integration concept does this illustrate?
Answer: Real-time event-driven integration
Real-time event-driven integration triggers immediate data updates across connected systems when a change event occurs in one system.
Which system provides automated, evidence-based recommendations or alerts to clinicians at the point of care to guide clinical decisions?
Answer: Clinical Decision Support System (CDSS)
A CDSS analyzes patient data against clinical knowledge bases to provide alerts, reminders, and recommendations at the point of care.
What is the purpose of a data dictionary in a health information system?
Answer: Define the structure, format, and meaning of each data element in the system
A data dictionary documents the metadata for each data element, including its name, definition, data type, and allowable values.
Which approach to system implementation involves replacing the old system entirely at a single cutover date rather than a gradual rollout?
Answer: Big bang (direct cutover) implementation
Big bang implementation replaces the legacy system all at once on a specific date, which is high risk but avoids operating dual systems simultaneously.
In healthcare IT, what does 'FHIR' stand for and what is its primary purpose?
Answer: Fast Healthcare Interoperability Resources — a standard for exchanging health data via web APIs
FHIR (Fast Healthcare Interoperability Resources) is an HL7 standard that uses modern web technologies (REST APIs) to enable health data exchange.
