To facilitate broader interoperability of health data around the globe to enhance and improve the delivery of healthcare, LOINC® from Regenstrief and SNOMED International have commenced the generation of The LOINC Ontology: A LOINC and SNOMED CT interoperability solution.
The LOINC Ontology supports providers and users who implement different combinations of SNOMED CT and LOINC in health information systems and allows them to meet clinical and regulatory requirements in a single solution. Linked together in a complementary way, SNOMED CT provides the computable framework and LOINC provides laboratory and pathology content in an understood format to countries who do not currently use LOINC.
This standardized terminology initiative to facilitate health information exchange provides new opportunities for the growth of LOINC and SNOMED adoption and appreciably improves interoperability between the two standards, which serve an intersecting group of global implementers. The LOINC Ontology is fully owned by Regenstrief Institute. It will be made available without charge under the existing LOINC royalty-free license. SNOMED International members and users will be able to work with LOINC in the same format they already use for SNOMED CT.
Each organization retains editorial control of its respective standards. To date, more than 24,000 LOINC terms are included in the LOINC ontology preview which will be published in the last quarter of the 2023 calendar year for review and feedback. “The LOINC Ontology, a LOINC and SNOMED CT interoperability solution, is novel and transformative in providing clinical observation content in an integrated format and accelerates interoperability and supports stakeholders with meeting clinical, regulatory and administrative requirements,” according to Marjorie Rallins, DPM, M.S., executive director of LOINC and Health Data Standards at Regenstrief.
LOINC, short for Logical Observation Identifiers Names and Codes, is a worldwide standard, used in 193 countries and available in 20 languages, for identifying health measurements, observations, and documents enabling the identification, exchange, and collection of data across health systems. Created and maintained at Regenstrief Institute, the system is free to users. Owned and governed by 48 global Members, SNOMED International is a not-for-profit organization that is charged with setting global standards for health terminology, a critical element of safe and effective healthcare. SNOMED CT is a comprehensive, multilingual healthcare terminology created for use by healthcare professionals to capture the care of individuals in an electronic health record and facilitate sharing, decision support, and analytics, to support safe and effective health information exchange.
