What is the term for a set of standards for the secure exchange of health information over the Internet?

The correct answer is the Nationwide Health Information Network (NHIN). This term refers to a set of standards, services, and policies that enable the secure exchange of health information over the Internet. The NHIN was developed to facilitate interoperability between different health information systems, ensuring that healthcare providers can exchange patient information securely and efficiently. This is critical for improving care coordination, enhancing patient safety, and streamlining healthcare processes.

On the other hand, niche applications refer to specific software solutions designed for particular tasks or populations, which do not encompass the broader standards for information exchange like NHIN does. Natural language processing involves the capability of computers to understand human language, which, while useful in health informatics, does not directly relate to standards for secure information exchange. Networked personal health records allow individuals to manage their own health information but are not comprehensive standards for secure data exchange on a wider scale. Thus, NHIN is the term that most accurately describes the set of standards for secure health information exchange.
