Which practice helps protect patient privacy when sharing data externally?

• A. Data De-identification
• B. Encryption at rest
• C. RACI chart
• D. Health information exchange

Answer: (A)

Protecting privacy when sharing data externally hinges on removing information that could identify a person. Data de-identification achieves this by stripping or generalizing identifiers so the dataset cannot reasonably be linked to an individual. Under HIPAA, this aligns with Safe Harbor rules or an expert determination that the risk of re-identification is very low. With de-identified data, researchers or external partners can analyze trends and gain insights without exposing patient identities. Encryption at rest protects data while it’s stored, but it doesn’t address privacy once the data are shared or used—once decrypted for use, identifiers could be exposed. A RACI chart focuses on roles and responsibilities, not privacy protections. Health information exchange is the process of moving data between organizations and doesn’t inherently protect privacy without applying de-identification and access controls. So, data de-identification is the practice that best maintains patient privacy when data are shared externally.
