Secondary use research is defined as:

Secondary use research is defined as:

• A. Research that relies on information originally collected for a purpose other than the current research purpose.
• B. Research that generates at least two publications.
• C. Original research that is copied by a second researcher.
• D. Research that relies on information collected for the current study.

Answer: (A)

Secondary use research means using information that was originally collected for a purpose other than the current research purpose. This includes data from patient records, administrative datasets, or samples gathered for care or another study that are analyzed for a new research question. This definition fits best because it centers on reusing existing information for a purpose different from its original one, which is the core idea of secondary use. The other statements describe aims like multiple publications, copying original research, or using data collected specifically for the current study—none of which capture the idea of reusing information gathered for another purpose.
