Which item would not be considered secondary data?

• A. Health record
• B. Pharmacy data
• C. Lab test results
• D. Insurance claims history

Answer: (A)

The main idea here is the difference between primary data and secondary data. Primary data are collected firsthand for the specific purpose at hand, while secondary data already exist for another purpose and are reused for a new purpose.

A health record is created during direct patient care to document clinical information, treatments, and outcomes. It’s the original source of information produced for patient management, so it’s considered primary data. The other items—pharmacy data, lab test results, and insurance claims history—are generated through routine operations for tasks like dispensing medications, performing tests, and billing. When these existing records are used for a study or analysis rather than data collected specifically for that study, they’re treated as secondary data.
