Which safeguards help protect privacy in public health research?

• A. Sharing raw data openly without restrictions
• B. Data de-identification, access controls, IRB oversight, and data use agreements
• C. Strengthening hospital penalties for noncompliance
• D. Banning all data collection

Answer: (B)

Safeguarding privacy in public health research hinges on combining technical, administrative, and ethical controls that limit who can access data, how it’s used, and how the research is reviewed. Data de-identification removes or masks personal identifiers so information can be analyzed without revealing who it belongs to, reducing the risk of re-identification. Access controls ensure that only authorized researchers can view or handle the data, and often require authentication and role-based permissions. IRB oversight provides independent review to ensure that privacy risks are identified and minimized, with safeguards in place to protect participants. Data use agreements spell out permitted uses, required security measures, and responsibilities to protect privacy, creating enforceable expectations about data handling. In contrast, openly sharing raw data without restrictions would significantly increase privacy risks; relying on penalties for noncompliance addresses behavior after a breach rather than preventing privacy problems, and banning all data collection would halt valuable public health research.
