Systems Flashcards

A hospital's system remains fully operational when one server fails because workload automatically shifts to a redundant server. This capability is called:

Answer: Failover

Failover is the automatic switching to a standby system when the primary system fails, ensuring continuous availability.

In systems analysis, a use case diagram is primarily used to illustrate:

Answer: Interactions between users (actors) and system functions

Use case diagrams depict how actors (users or external systems) interact with the system's functional capabilities.

Which system implementation strategy goes live with the new system at all locations simultaneously, replacing the old system completely?

Answer: Big bang (direct cutover) implementation

Direct cutover (big bang) switches all users to the new system at once on a set date, with the old system decommissioned immediately.

An audit trail in an EHR system records which of the following?

Answer: Who accessed or modified a record, what was changed, and when

An audit trail logs user access events, record modifications, timestamps, and user identities to support accountability and compliance.

The concept of 'data at rest' encryption in a healthcare system refers to protecting data:

Answer: Stored on servers, hard drives, or backup media

Data at rest encryption secures stored data (on disks, databases, or backups) so it is unreadable without proper decryption keys.

A health system connects multiple regional hospitals so they can share patient records in real time. This regional network is called a(n):

Answer: Health Information Exchange (HIE)

A Health Information Exchange (HIE) enables the electronic sharing of health information across different organizations in a region.

System downtime procedures in a hospital HIM department are designed to:

Answer: Allow manual, paper-based workflows until the system is restored

Downtime procedures establish manual backup processes so clinical and administrative operations can continue during system outages.
