What does HIPAA's "minimum necessary" standard apply to in human subjects research?

The "minimum necessary" standard of HIPAA (Health Insurance Portability and Accountability Act) specifically pertains to the use and disclosure of Protected Health Information (PHI) in a manner that minimizes the amount of such information that is accessed or used while still meeting the needs of the research. This standard applies to all human subjects research that uses PHI without obtaining subject authorization.

In cases where researchers are using PHI without authorization, it becomes crucial to adhere to the minimum necessary standard to ensure that only the essential information required to conduct the study is utilized. This approach not only protects the privacy of the individuals whose data is being used but also complies with HIPAA's regulations designed to safeguard personal health information.

Other options would not appropriately capture the essence of the minimum necessary standard as it specifically pertains to the usage of PHI. For instance, research involving personal health information with subject authorization does not fall under this standard since the individuals have given explicit consent, thus negating the need for minimum necessary restrictions. Similarly, studies that do not involve personal health information or those simply approved by an Institutional Review Board do not relate to HIPAA's minimum necessary requirements, as they do not engage with the fundamental concern of protecting sensitive health data.
