Regenstrief and SNOMED International have broadened their collaboration to drive health data interoperability between LOINC and SNOMED CT data standards.

– Regenstrief Institute and SNOMED International have announced the LOINC Ontology, a standardized terminology initiative focused on facilitating broader health data interoperability.

The LOINC Ontology aims to support providers and users who implement different combinations of SNOMED CT and LOINC data standards through a single solution. Linked together, SNOMED CT provides the computable framework, and LOINC provides laboratory and pathology content in an understood format to countries that do not currently leverage LOINC.

The standardized terminology initiative provides new opportunities for advancing LOINC and SNOMED adoption and driving interoperability between the two standards.

Vaultara allows for rapid, contact-less access to essential imaging data and improved efficiency.

Plus a reduction in operational costs associated with medical image sharing.

LOINC, short for Logical Observation Identifiers Names and Codes, is a worldwide data standard used in 193 countries and available in 20 languages. The standard identifies health measurements, observations, and documents to support the identification, exchange, and collection of health data. Regenstrief Institute created and maintains the system, which is free to users.

“Significant commitment and collaboration has been invested by both teams to produce the LOINC ontology preview,” said Don Sweete, SNOMED International CEO. “This serves as an excellent illustration of how we have leveraged our mutual expertise to further the goal of interoperability for implementers globally.”

SNOMED International is a not-for-profit organization charged with setting global standards for health terminology. SNOMED CT is a comprehensive, multilingual healthcare terminology created to capture the care of individuals in EHR platforms and facilitate data sharing, clinical decision support, and analytics.

SNOWMED International and Regenstrief signed a collaborative agreement in 2022 which laid the foundation for the LOINC extension of SNOMED CT.
