This study presents a methodology for constructing a Traditional Chinese Medicine (TCM) semantic network system based on SNOMED CT, addressing challenges in terminology standardization and knowledge integration within the TCM domain. By analyzing SNOMED CT's framework and encoding rules, and incorporating TCM-specific features (e.g., property-channel tropism, efficacy classification), we designed an ontological model encompassing core concepts, attribute relationships, and terminology mapping. The system employs semantic web technologies (e.g., RDF, OWL) to establish hierarchical and associative relationships among TCM concepts (e.g., "incompatibility," "pharmacological effects") while ensuring compatibility with SNOMED CT for international standardization. Experimental validation involved constructing a prototype semantic network (e.g., nodes for Astragalus membranaceus) to demonstrate the system's efficacy in terminology normalization, knowledge reasoning, and cross-domain data linkage. This research provides a feasible solution for standardizing and enabling intelligent applications (e.g., clinical decision support, big data analytics) of TCM knowledge, while expanding SNOMED CT's applicability to traditional medicine. It aims to foster integration between TCM and Western medicine and advance the modernization and digitization of TCM through foundational semantic infrastructure.

Syadem and SNOMED International announce release of the Unified Nomenclature of Vaccines Extension Back 8 May 2025 Back SNOMED International and Syadem are pleased to announce the release of the Unified Nomenclature of Vaccines ( NUVA ) Extension. France-based Syadem owns and manages NUVA, a terminology used to capture, interpret, and process records of administered vaccines. SNOMED CT is a comprehensive, multilingual healthcare terminology created for use by healthcare professionals. It enables the care of individuals to be captured in electronic health records, facilitating information sharing, decision support and analytics for safe and effective health information exchange. SYADEM participates in the European Vaccination beyond COVID (EUVABECO) project, which is co-funded by the European Commission under the eU4Health program . By mid 2026, EUVABECO will deliver implementation plans for innovative vaccination practices to EU Member States. The plans will support the operationalization of several tools including a portable European Vaccination Card (EVC). NUVA is the intended code system for documenting administered vaccines in the EVC. The release follows the April 2024 announcement of the formal collaboration between the two organizations, which was formed to facilitate the creation of comprehensive vaccination histories for individuals over time, regardless of the original vaccine source and data format. The partners also agreed to collaborate to integrate NUVA content as an extension in SNOMED International’s Community Content Area, define processes for ensuring content alignment, and, where relevant, include NUVA concepts in the SNOMED CT International Edition. The NUVA Extension includes all of the NUVA vaccine content, including branded products, valences and medicinal product role. It facilitates alignment with, and strengthens access to, vaccine content in a SNOMED CT format, supporting both clinical and regulatory requirements for vaccine information. “Team members from both organizations have made considerable progress in achieving the goals we agreed upon a year ago,” says SNOMED International CEO Don Sweete. “As we watch a growing measles crisis unfold in North America and bird flu continue to spread, we see that the risks to human health from vaccine-preventable illnesses have not diminished in that time, and in fact, continue to increase. Our work together helps ensure the world can respond more quickly and effectively to these ongoing challenges.” “Three years ago, we realized how helpful our NUVA terminology could be to the digital health community and made the decision to offer it as a global common good,” says SYADEM scientific director Jean-Louis Koeck. “SNOMED International immediately grasped the value of that idea and helped us in maturing this solution. Now, with this first release and the constitution of a supporting network of vaccine coding experts through the International Vaccine Codes Initiative (IVC), it becomes a reality.” International Summit on Vaccine Coding & Standards Conference The SNOMED International team participating in the NUVA collaboration work are attending the International Summit on Vaccine Coding & Standards Conference on May 9, 2025, in Bordeaux, France, where the release will be formally announced. Co-organized by the American Immunization Registry Association and Syadem, the event will focus on advancing global vaccine interoperability through the International Vaccine Codes Initiative (IVC) and NUVA. The teams will also provide technical information about the NUVA Extension and alignment with SNOMED CT, and discuss the importance and benefits of the collaboration between the two organizations.

Disaster hazard research conducted by Australia’s Monash University leads to new SNOMED CT content Back 19 Jan 2024 Back Upon receiving a request from SNOMED International Member, Australia , the organization recently incorporated new and relevant climate and natural disaster concepts in the International Edition of SNOMED CT. Fulfilment of the request exemplifies the multifaceted and collaborative processes that drive the ongoing development and improvement of SNOMED CT, the world’s most comprehensive clinical terminology. Signalling the effectiveness of the content development process, it is the users, Members, researchers, clinicians and other stakeholders that identify gaps and work together with SNOMED International to discuss, model and include relevant content in SNOMED CT. The request for inclusion of climate content in SNOMED CT was driven by the findings of a study titled Evaluating the representation of disaster hazards in SNOMED CT: gaps and opportunities , published in the Journal of the American Medical Informatics Association , in which researchers from Australia’s Monash University examined gaps in clinical terminologies available to healthcare professionals during disaster-related events. In particular, it found meteorological, hydrological, extraterrestrial, geohazard, environmental, technological and societal content required coverage in SNOMED CT. The study, which mapped the United Nations Office for Disaster Risk Reduction-International Science Council ’s Hazard Information Profiles to SNOMED CT, provided a list of concepts in which climate and disaster related content fell short in SNOMED CT. For example, research revealed that SNOMED CT lacked content related to “heatwave” and “drought,” phenomena that have intensified due to climate change and that have significant impacts on human health, migration patterns and armed conflict situations globally. In response, approximately 90 percent of the requested missing concepts identified in the study and submitted by Australia’s SNOMED CT National Release Centre (NRC) have been included in SNOMED CT. “SNOMED International recognizes the work of researchers who authored this report along with the Australian NRC for requesting the addition of this content,” says SNOMED International Chief Terminologist Dr. James Case. “As an agile standards development organization, this is a great example of how we engage and work with Members to prioritize and respond to their content requests. This ensures clinical and environmental changes on the ground, including promotion of relevant content to the International Edition, are addressed as quickly as possible.” With SNOMED International’s move to releasing the International Edition monthly, the content will be available to users more quickly than in the past, when the International Edition was published twice a year. The addition of climate and natural disaster related content received, reviewed and quality assured by SNOMED International in late June of 2023 is a prime use case for the move to frequent releases, as was the rapid inclusion of COVID-19 content at the beginning of the global pandemic in 2020. The study also noted the major role that nursing, the largest professional group in healthcare, plays in defining the health indicators that will be important in the overall monitoring of health interventions to support communities in disaster mitigation, preparation, response and recovery, and climate change adaptation and mitigation. The 2021 integration of the International Classification for Nursing Practice into SNOMED CT and release as a reference set will help providers and policymakers better plan, implement and evaluate the effectiveness and impact of policies, procedures and actions related to a broad array of disaster events. ABOUT SNOMED INTERNATIONAL SNOMED International is a not-for-profit organization that owns and develops SNOMED CT, the world's most comprehensive healthcare terminology product.

The department of neurosurgery at University Hospitals Leuven, in collaboration with a terminologist, established a standardized complication registration system through an iterative consensus process. Following rigorous clinical review, 102 complications were selected, resulting in a final list of 100 concepts (91 unique SNOMED CT identifiers). Complications were categorized as: intraoperative, postoperative surgical, postoperative medical. To enable tracking the absence of complications and the proportion of completed registrations, a 'no complication' category was also included. Our standardized complication registry has been clinically operational since February 1, 2023. It documents all neurosurgical procedures (N=3501) with SNOMED CT-coded complications (or their absence) linked to surgical procedures (using local codes) in the electronic patient record (EPR) problem list and covers the period from surgery through 6 weeks of postoperative follow-up. Analysis through April 21, 2025 shows 92% coverage. Our datawarehouse integrates these procedures and complications with laboratory results, imaging reports, medications, readmissions, and survival data - providing clinicians with comprehensive patient overviews and enabling the identification of clinically relevant patterns over time Key features 1. Clinical utility: Surgeons register the complications directly in workflow using EPR templates 2. Terminology flexibility: Light version of post-coordination when needed (MRCM-compliant) 3. Future-ready: * Architecture permits eventual Clavien-Dindo integration (Grade I-V severity scoring) * Technical foundations exist for SNOMED CT procedural coding (requiring future IT development) This implementation demonstrates how SNOMED CT can support surgical outcome monitoring while pragmatically accommodating existing systems. The multidimensional linkage will enable both quality benchmarking and research applications in the future.

SNOMED responds to community call for improved diabetes insipidus terminology in SNOMED CT Back 12 Feb 2024 Back SNOMED International, responding to an external request from an international group of representatives of national and international endocrinology, nephrology and pediatric societies, is improving concepts referring to diabetes insipidus in SNOMED CT. Existing diabetes insipidus concepts will be renamed or replaced with new concepts representing current terminology for this disorder. In October 2022, the Working Group for Renaming Diabetes Insipidus published a paper outlining the rationale for the retirement of the term “diabetes insipidus” and the replacement with terms that more appropriately represent the pathophysiology of this set of conditions. Since then, a number of professional societies, as well as UpToDate , a primary source of truth for SNOMED CT, have endorsed the proposed changes, which have also been adopted by a number of primary references. A November 2022 Springer article , titled ‘ What’s in a name? That which we call diabetes does not taste sweet!’ says most health care professionals are familiar with the term “diabetes,” a shortening of the name for the common disorder “diabetes mellitus,” but the term “diabetes insipidus” is rare and many practitioners are unfamiliar with the diagnosis and its pathophysiology and management, leading to potentially serious consequences for patients. Concepts previously referring to diabetes insipidus in the SNOMED CT International Edition are affected by the changes. For each of the affected terms, either a name change or a replacement term was created to reflect the current terminology as determined by the expert group. The primary focus was to reflect the newer terminology of “arginine-vasopressin deficiency” or “arginine-vasopressin resistance,” which have been verified by subject matter experts to ensure clinical veracity to either central or nephrogenic etiologies. “We’re excited to provide the updated content related to this condition, and, hopefully, building greater awareness through correct terminology so providers have the information they need to accurately diagnose and treat patients,” says SNOMED International Chief Terminologist Dr James Case. “This process is a perfect example of how our community and SNOMED International work together to continually develop and improve SNOMED CT.” “This new nomenclature is an important step for patient safety, as many healthcare practitioners have confused diabetes insipidus with the much more common diabetes mellitus, which led to unnecessary blood sugar measurements but also much worse consequences including death,” explains Mirjam Christ-Crain, MD PhD, Professor of Endocrinology, University Hospital Basel, Switzerland. As a member of the working group to rename diabetes insipidus, I am extremely grateful to SNOMED International for this pragmatic implementation of the new names. We are already now experiencing that the new name is widely accepted, among physicians and patients alike,” she adds. The content changes have been completed and are scheduled for the February 2024 International release of SNOMED CT. Contact info@snomed.org for a list of the affected concepts.

Semantic interoperability of laboratory data is essential for enabling secondary use in research networks like the German Medical Informatics Initiative (MII). While the MII's Lab Module provides standardized HL7 FHIR-based structures for laboratory parameters using LOINC codes, harmonizing these data across institutions for analytics remains a significant challenge. This project investigates the use of precoordinated LOINC-SNOMED expressions as a scalable, computable alternative to manual aggregation mappings, aiming to support a wide range of research questions with varying data granularity needs and to lay the groundwork for future integration of increasingly precise laboratory coding, such as the growing number of LOINC codes for established domains like immunohistochemistry in oncology. Back View Map Charité Berlin / Berlin Institute Of Health (1 of 2) Beyond Manual Mappings: LOINC-SNOMED Ontology as a Computable Solution for Laboratory Data Harmonization in the MII Read More Country / Region EMEA Tags Data analytics, Mapping, Research Semantic interoperability of laboratory data is essential for enabling secondary use in research networks like the German Medical Informatics Initiative (MII). While the MII's Lab Module provides standardized HL7 FHIR-based structures for laboratory parameters using LOINC codes, harmonizing these data across institutions for analytics remains a significant challenge.

Description The scope of this project centers on evaluating approaches for aggregating laboratory data across multiple university hospitals participating in the MII. Specifically, we compared the traditional, manually curated LOINC-to-parent mappings from the INTERPOLAR project with the automated, ontology-driven relationships provided by the LOINC-SNOMED Ontology. The challenge is the harmonization of different laboratory parameters across a multitude of university hospitals. As an example: In addition to "1751-7 Albumin [Mass/volume] in Serum or Plasma", there exist at least 10 different LOINCs describing similar concepts without being identical or interchangeable at the analytical level. Our analysis focused on the 300 most frequently used laboratory parameters, assessing how each approach supports dynamic value set generation for analytics platforms. This enables researchers to quickly determine the number of patients or analyte-related measurements available for study, without resorting to overly broad aggregation that could compromise clinical relevance. The project also explores how these methods can be extended to support the integration of new, more precise LOINC codes, which facilitate structured data collection and sharing in established laboratory domains. Scope SNOMED CT was selected for its robust ontology, hierarchical relationships, and capacity for formal logical definitions. These features make it uniquely suited for supporting computable aggregation and semantic interoperability across diverse and evolving laboratory data sets. The ability to dynamically generate and expand value sets, particularly as new and more precise laboratory parameters and codes become available, positions SNOMED CT as a future-proof solution for large-scale data harmonization and analytics. The LOINC-SNOMED-Ontology is an important publically available ressource usable to aggregate different LOINCs under similar concepts. This integration with LOINC further enhances its utility for laboratory data, supporting both broad and granular research needs. How SNOMED CT will be used SNOMED CT is utilized in this project through precoordinated expressions that integrate LOINC terms as formal, computable SNOMED CT concepts in the LOINC SNOMED Ontology. This integration allows for the logical representation of laboratory parameters within SNOMED CT's hierarchical structure, enabling automated reasoning and dynamic generation of value sets. The LOINC-SNOMED Browser and downloadable distribution files are employed as a key tool for validating and visualizing both manual and ontology-based mappings, facilitating real-time exploration and identification of gaps or inconsistencies.

New process launches for proposing changes to the International Patient Summary Back 29 Sept 2025 Back A new process is now available for clinicians, standards experts, and implementers to propose changes to the International Patient Summary “suite” of standards. The International Patient Summary (IPS) is a standardized set of basic clinical data, supported by a “suite” of standards artefacts, that includes the most important health and care related facts required to ensure safe and efficient exchange of a patient’s health data across geographic borders, organizations, and health systems, independent of the country, clinical specialty, or medical condition. The publication of IPS artefacts began in 2018, with regular subsequent updates. At the 2021 UK G7 Summit, health leaders embraced the IPS, underscoring the vital importance of digital health interoperability in delivering safer, more effective care for patients around the world. In the years since, this vision has been entrusted to the Global Digital Health Partnership (GDHP), a collaboration of governments and organizations working to align digital health efforts globally. This collaboration has boosted the uptake of the IPS across the globe. The IPS has been adopted by a growing number of countries and organizations, including countries in the Middle East and South East Asia, (most notably the annual Hajj pilgrimage); Latin America and the Caribbean; Brazil; New Zealand; the European Union, and Canada. With heightened uptake of the IPS globally, it's critical for implementers to have a mechanism to propose changes to the IPS to ensure the standards remain relevant, accurate and globally applicable. A committee of the Joint Initiative Council for Global Health Informatics Standardization (JIC), the IPS Coordination Committee (IPSCC), provides a dedicated open forum for collaborating standards development organizations. Through the IPSCC they coordinate their advancement of the IPS suite of standards. IPSCC membership includes, but is not limited to, representation from: CEN/TC 251, HL7 International, IHE International, ISO/TC 215 and SNOMED International. All stakeholders are encouraged to propose changes based on their real world experience with the IPS. Such proposed changes can include, improvements and corrections to existing IPS standards, enhancements to the scope of standards, or the addition of new standards to support the implementation and use of the IPS. Current JIC Chair, Dan Vreeman (HL7), notes that as the IPS continues to gain traction globally and as it becomes more broadly deployed, it is easier to identify aspects of the IPS that require improvements, tweaks and enhancements. “We thank the pioneers who were among the first to adopt and deploy the IPS as they are well-positioned to provide feedback and suggest ways as we continue to evolve the process.” IPSCC Chair, Robert Stegwee (CEN), offers, “The IPS Coordination Committee is committed to provide transparent guidance and alignment for the ongoing development of the IPS. Real-world experience is invaluable in helping maintain the standards’ relevance, accuracy and usability, and it is through this new “Change Proposal” process that we strengthen our ties to users around the world.” Visit the International Patient Summary website to propose a change and contribute to the ongoing development of the IPS. ABOUT THE JIC The Joint Initiative Council on Global Health Informatics Standardization (JIC) is a collaboration of SDOs that seeks to enable common, timely digital health standards by addressing and resolving issues, gaps, overlaps, and redundant standardisation efforts. ABOUT THE IPSCC The IPS Coordination Committee brings together global standards development organizations to guide and align the standards artefacts that constitute the International Patient Summary (IPS). By coordinating across standards bodies, the IPSCC ensures the IPS remains a trusted, consistent, and globally applicable standard for the safe exchange of essential health information.
