Under HIPAA's Minimum Necessary Standard, which practice is MOST appropriate when a health plan requests patient records?

In healthcare data management, what does 'referential integrity' mean?
Answer: Foreign key values in one table must correspond to existing primary key values in another table
Referential integrity is a database constraint ensuring relationships between tables remain consistent through valid foreign key references.
Which type of healthcare data is MOST likely to be collected through passive surveillance rather than active data collection?
Answer: Claims data from insurance billing systems
Claims data is generated automatically as a byproduct of billing and reimbursement without requiring extra effort to collect.
Which challenge is UNIQUE to analyzing Electronic Health Record (EHR) data compared to data collected in structured clinical trials?
Answer: High levels of missing data and variation in documentation practices across providers
EHR data suffers from informative missingness and inconsistent documentation since it is created for care delivery, not research.
A hospital wants to benchmark its readmission rates against national averages. Which data source would be MOST appropriate for this comparison?
