Enhancing the Logical Observation Identifiers Names and Codes Standard to Support U.S. Interoperability

Logical Observation Identifiers Names and Codes (LOINC®) is a universal coding system for health measurements, observations, and documents. The LOINC vocabulary standard is owned and developed by the Regenstrief Institute, Inc, and distributed worldwide at no cost under an open license. LOINC’s widespread implementation, adoption, and required use have made it a key and ubiquitous component of interoperable health IT solutions in the United States. In collaboration with the ONC and the diverse LOINC user community, our aims are to improve LOINC’s technical infrastructure, enrich LOINC’s content, and enhance tools for accessing its content, including via a FHIR-based terminology services Application Programming Interface (API). Accomplishing these objectives will advance interoperable health IT and better position LOINC to support the continued evolution of the USCDI.
