Which principle focuses on the protection of personal health information from unauthorized access?

The principle that focuses on the protection of personal health information from unauthorized access is confidentiality. This principle is foundational in health information management, as it establishes the expectation that individuals' health data will be handled with privacy in mind, ensuring that sensitive information is shared only with authorized individuals or entities.

Confidentiality ensures that personal health information is not disclosed without appropriate consent, reinforcing trust between patients and healthcare providers. It is crucial for maintaining the ethical standards of the healthcare profession, as well as complying with laws and regulations designed to protect personal data.

While integrity pertains to the accuracy and completeness of information, and availability refers to ensuring that information is accessible to authorized users when needed, security encompasses measures and protocols put in place to protect both confidentiality and integrity. However, it is confidentiality that specifically addresses the concern of unauthorized access to personal health information.
