Read the first 7 Information Systems flashcards as text

  1. Which security mechanism in health information systems ensures that data has not been altered during transmission?

    Answer: Data integrity controls (e.g., hashing)

    Hashing algorithms such as SHA-256 generate a unique digest of data; any alteration changes the hash, detecting tampering in transit.

  2. A radiology department uses a system to store and retrieve medical images. What is this system called?

    Answer: PACS (Picture Archiving and Communication System)

    PACS stores, retrieves, manages, and transmits digital medical images such as X-rays, CT scans, and MRIs.

  3. What does 'uptime' refer to in the context of healthcare information system availability metrics?

    Answer: The percentage of time a system is operational and accessible

    Uptime measures the proportion of time a system is available and functioning, often expressed as a percentage (e.g., 99.9%).

  4. Which approach to EHR implementation involves replacing the existing system all at once on a specific go-live date?

    Answer: Big bang implementation

    A big bang implementation switches from the old system to the new one simultaneously across all departments on a single go-live date.

  5. In healthcare IT governance, what is the primary role of a steering committee for an information system project?

    Answer: Providing strategic oversight and prioritizing resources across projects

    A steering committee provides executive-level governance, aligning IT projects with organizational strategy and allocating resources.

  6. Which type of system integration connects applications directly to each other without a central broker, creating a complex 'spaghetti' architecture?

    Answer: Point-to-point integration

    Point-to-point integration directly links each pair of systems, which becomes difficult to maintain as the number of systems grows.

  7. A health system is migrating data from an old EHR to a new one. What process ensures that the migrated data accurately reflects the original records?

    Answer: Data validation and reconciliation

    Data validation and reconciliation compare source and target datasets to confirm completeness and accuracy of the migration.
