CDS Data Lifecycle Management Flashcards

Which stage of the data lifecycle involves formally retiring data from active use while preserving it for potential future reference?

Answer: Data archiving

Data archiving moves data out of active systems but retains it in long-term storage for compliance or historical reference.

A US healthcare organization must retain patient records for a minimum of how many years under HIPAA guidelines?

Answer: 6 years

HIPAA requires covered entities to retain medical records documentation for a minimum of 6 years from creation or last effective date.

What is the primary purpose of a data retention schedule in a data lifecycle management program?

Answer: To define how long each data category must be kept and when it should be destroyed

A data retention schedule specifies retention periods and disposal rules for each data category, ensuring legal compliance and reducing storage costs.

Which disposal method is considered most appropriate for destroying sensitive data stored on magnetic hard drives?

Answer: Degaussing or physical destruction

Degaussing disrupts the magnetic field rendering data unrecoverable, and physical destruction ensures no data can be extracted from the media.

In data lifecycle management, what does 'data provenance' refer to?

Answer: The documented history of data's origin, movement, and transformations

Data provenance tracks the origin, custody chain, and all transformations a dataset has undergone, supporting auditability and trust.

Which activity is part of the 'data creation' stage in a typical data lifecycle model?

Answer: Validating data at point of entry against defined standards

Entry validation at the creation stage ensures data meets quality and format standards before it enters downstream systems.
