Glossary

A Fast Healthcare Interoperability Resources® (FHIR®) profile is a set of requirements and constraints placed on a resource. It can describe general features the system supports for that resource or information handled or produced according to a specific use case. Often, they include rules about which application programming interface features, terminologies, or resource elements the FHIR profile uses or does not use.

The feasibility criterion assesses the extent to which the specifications, including measure logic, require readily available data or could be captured without undue burden and can be implemented for performance measurement. 

The Federal Register is the official daily publication for rules, proposed rules, and notices of federal agencies and organizations, as well as executive orders and other presidential documents. The Federal Register is published by the Office of the Federal Register, National Archives and Records Administration.

Fast Healthcare Interoperability Resources® (FHIR®) is an open-source Health Level Seven International® (HL7®) standard for exchanging healthcare information electronically. FHIR provides a consistent, flexible way for different health information technology (IT) systems—such as electronic health records (EHRs), labs, and apps—to share data quickly and securely.

The Fast Healthcare Interoperability Resources® (FHIR®) Implementation Guide (IG) Registry is a centralized repository or catalog that stores and organizes IGs, which are structured documents providing instructions for how to implement specific technical standards, usually in the context of healthcare interoperability. These guides often define how data should be formatted, exchanged, and interpreted to ensure systems can communicate consistently.

The Fast Healthcare Interoperability Resources® (FHIR®) Terminology Service for Value Set Authority Center (VSAC) Resources is an online service that permits access to value sets and code systems. It works through a Representational State Transfer Application Programming Interface (REST API), so it’s designed for people who are familiar with FHIR resources. Access requires a free Unified Medical Language System (UMLS) license.

Future state is a model integrating the downstream work of informatics, implementation, communication, and evaluation into the guideline or measure development process.
