Which component of the FHIR specification defines the data elements, constraints, and extensions for a specific resource use case?
Answer: StructureDefinition
A FHIR StructureDefinition formally describes the structure, constraints, and extensions applied to a base FHIR resource for a specific use case.
A health system is selecting an EHR. Which procurement step involves vendors demonstrating their system meets specified functional requirements in a controlled scenario?
Answer: Scripted demonstration
Scripted demonstrations require vendors to show specific workflows using predefined scripts, allowing direct comparison against functional requirements.
In population health management, a registry most directly supports care by:
Answer: Identifying patients due for preventive services or follow-up
Disease registries aggregate patient data to proactively identify care gaps and trigger outreach for patients needing preventive or follow-up care.
Which security control best addresses the risk of an employee accessing PHI unrelated to their job duties?
Answer: Role-based access control (RBAC)
RBAC limits PHI access based on a user's organizational role, ensuring employees can only view information relevant to their job functions.
The ONC's 21st Century Cures Act final rule primarily targets:
Answer: Prohibiting information blocking and advancing interoperability
The ONC 21st Century Cures Act final rule defines information blocking prohibitions and requires standardized FHIR-based API access to patient data.
When calculating the positive predictive value (PPV) of a screening test, which variables are required?
Answer: True positives and false positives
PPV = True Positives / (True Positives + False Positives), representing the probability that a positive test result is a true case.
A health system implements a sepsis early warning algorithm. To evaluate its real-world performance, which method compares algorithm predictions against actual patient outcomes in production?
Answer: Prospective surveillance with post-hoc outcome linkage
Prospective surveillance with outcome linkage monitors algorithm alerts in real time and links them to confirmed sepsis diagnoses to assess production performance.
