What legal term describes a patient's right to control certain personal information?

The term that best describes a patient's right to control certain personal information is "privacy." Privacy pertains to an individual's ability to manage and protect their personal information from being disclosed or accessed by others without their consent. This right is fundamental in healthcare, as it honors the individual's autonomy and confidentiality regarding their sensitive health information.

While confidentiality is related and involves the obligation of healthcare providers to protect patient information from unauthorized access or disclosure, it is more about the duty of the provider rather than the right of the patient. Access, on the other hand, refers to the patient's ability to obtain their health information, and security relates to the measures taken to safeguard that information. Thus, privacy encapsulates the broader concept of a patient’s control and discretion over their own personal information.
