Which action is prohibited under HIPAA regulations?

The action of sharing PHI (Protected Health Information) without patient authorization is clearly prohibited under HIPAA regulations. HIPAA is designed to protect individuals' medical records and other personal health information, ensuring that such sensitive information is not disclosed without proper consent.

Under HIPAA, healthcare providers, plans, and clearinghouses are required to take steps to safeguard patients' information and maintain confidentiality. When patients seek medical care, they often provide sensitive information under the assumption that it will remain private. If a healthcare provider were to share this information without authorization, it would violate patients' rights and erode trust in the healthcare system.

In contrast, using patient identifiers in research with consent, documenting patient care in secure electronic systems, and training staff on privacy practices are all acceptable actions as long as they comply with HIPAA guidelines. Each of these activities is necessary for quality healthcare delivery, patient safety, and staff education. Ultimately, maintaining strict control over the sharing of PHI ensures the privacy and security of patient information, which is a cornerstone of HIPAA's mission.
