What term describes a legal framework that ensures confidentiality, integrity, and availability of medical information?

The correct term that describes a legal framework ensuring the confidentiality, integrity, and availability of medical information is HIPAA (Health Insurance Portability and Accountability Act). HIPAA was enacted in the United States to protect sensitive patient health information from being disclosed without the patient's consent or knowledge. This legislation includes provisions for the secure handling, storage, and transmission of healthcare data, thus ensuring its confidentiality, maintaining its integrity, and guaranteeing its availability when needed. These characteristics are critical in a medical context where the protection of personal health information is paramount.

The other choices represent legal frameworks that focus on different areas. SOX (Sarbanes-Oxley Act) pertains primarily to financial accountability in publicly traded companies, addressing issues related to corporate governance and accountability. PCI DSS (Payment Card Industry Data Security Standard) relates to the protection of payment card information, focusing specifically on data security within credit card transactions. FISMA (Federal Information Security Management Act) sets requirements for federal agencies regarding information security but is not specific to medical information. Each of these serves important functions within their respective domains, but only HIPAA is specifically designed to safeguard medical information.
