Case MS, DVM, PhD, FACMI Chief Terminologist, SNOMED International AUGUST 25, 2021 SNOMED International: Delivering CT What do we mean by ● Clinical meaning captured specifically and explicitly semantic ○ Granularity harmonization? ○ No implied meaning ○ Computable definitions In the context of healthcare ● Lossless transfer between terminology standards, systems harmonization is interpreted ● Bidirectional equivalence maps as the maintenance of fidelity ● Compatible with multiple of meaning of data information models throughout its lifecycle, ● Meaning maintained when unaffected by mappings or translated to another language translation. 2 SNOMED International: Delivering CT What is the greatest opportunity for harmonizing terminology standards? ● Identification of a subset of high priority, robust, fit-for-purpose standards ○ “The nice thing about standards is that there are so many of them to choose from.” - Andrew S. Tanenbaum ○ Reliably maintained, frequent releases ○ Focus on enhancement (comprehensive coverage) ○ USCDI is a good start (limited scope) ● Collaboration among SDOs (formal agreements) ● Joint Initiative Council for Global Health Informatics Standardization (JIC) Focus on a small set of “fit-for-purpose” standards. Agreement needed for SDOs to work together 3 SNOMED International: Delivering CT What are the greatest barriers to semantic harmonization? How do we move the barrier? • Leverage experiences in other ● Extensive use of local code sets (lack of adoption of countries standards) • National strategic plan developed ● Different underlying models and editorial policies of in collaboration with stakeholders terminologies ○ vendors ● Different primary focus of terminology standards ○ healthcare enterprises ○ clinical, administrative, reimbursement, classification, use-case specificity ○ payers ● Deeply entrenched implementations ○ government ● Reluctance to change/cost of change ○ SDOs ● Intellectual property constraints • Demonstration of the benefits ○ Real-World examples Barriers are long-standing, solutions will take a long time.

  • Identifying Clinical Terms in Medical Text Using Ontology-Guided Machine Learning
    JMIR MEDICAL INFORMATICS Arbabi et al Original Paper Identifying Clinical Terms in Medical Text Using Ontology-Guided Machine Learning Aryan Arbabi1,2, MSc; David R Adams3, MD, PhD; Sanja Fidler1, PhD; Michael Brudno1,2, PhD 1Department of Computer Science, University of Toronto, Toronto, ON, Canada 2Centre for Computational Medicine, Hospital for Sick Children, Toronto, ON, Canada 3Section on Human Biochemical Genetics, National Human Genome Research Institute, National Institutes of Health, Bethesda, MD, United States Corresponding Author: Michael Brudno, PhD Department of Computer Science University of Toronto 10 King©s College Road, SF 3303 Toronto, ON, M5S 3G4 Canada Phone: 1 4169782589 Email: [email protected] Abstract Background: Automatic recognition of medical concepts in unstructured text is an important component of many clinical and research applications, and its accuracy has a large impact on electronic health record analysis. The mining of medical concepts is complicated by the broad use of synonyms and nonstandard terms in medical documents. Objective: We present a machine learning model for concept recognition in large unstructured text, which optimizes the use of ontological structures and can identify previously unobserved synonyms for concepts in the ontology. Methods: We present a neural dictionary model that can be used to predict if a phrase is synonymous to a concept in a reference ontology. Our model, called the Neural Concept Recognizer (NCR), uses a convolutional neural network to encode input phrases and then rank medical concepts based on the similarity in that space. It uses the hierarchical structure provided by the biomedical ontology as an implicit prior embedding to better learn embedding of various terms.

  • Snomed Ct® and 3M™ Hdd: the Successful Implementation Strategy
    SNOMED CT® AND 3M™ HDD: THE SUCCESSFUL IMPLEMENTATION STRATEGY Federal Health Care Agencies Take the Lead The United States government has taken a leading role in the use of health information technologies to enhance the quality of patient care. Considered by leaders in health care technology to be a necessary step towards the enhancement of patient care, a 5-year, nationwide license for SNOMED Clinical Terms® (SNOMED CT®) was purchased by agencies of the Department of Health and Human Services for perpetual use by any governmental or eligible public, for- profit and non-profit organization located, incorporated and operating in the U.S. A comprehensive, widely accessible controlled medical vocabulary (CMV) such as this is deemed a required part of any integrated clinical information system that provides the communication of accurate, detailed patient information. In January 2004 the National Library of Medicine (NLM) of the National Institutes of Health will make SNOMED CT® available via the Unified Medical Language System® (UMLS). This comprehensive set of encoded medical concepts will work within a framework of interoperability standards for the electronic exchange of clinical health information. SNOMED – CT® will be incorporated into this common set of health care information technologies to support numerous efforts within the health care industry. Projects - such as the National Health Information Infrastructure (NHII) and the paperless electronic health record - have been outlined through collaborations between industry leaders, health care associations, and the U.S. government. The widespread use of an integrated set of health information standards is considered to be essential for the success of such projects, which have the potential for improving the quality of health-related services through the seamless exchange of accurate information.

    Benefits of SNOMED CT from a clinical perspective; The Rotherham experience Tuesday 9 April 2019 SNOMED International – Business MeetinGs 2019, London, UK Monica Jones – Associate Director of Information Services TRFT & Population Health ManaGement Lead for YHCR Agenda This presentation will provide an honest account drawing on real life experience of how using SNOMED CT has impacted the Rotherham NHS Foundation Trust, over the past six years, offering insight on the processes and challenges as well as sharing lessons learned. This session focuses on the clinical benefits of implementing SNOMED CT, gaining valuable insight from a trust that has already made the changeover. From practical necessities to wider service implications, these insights and 'top tips' will enable colleagues to accurately predict and overcome likely challenges. Rotherham NHS FT - Health Informatics • A fully co-terminus health and social care community with a population of c260,000 • ‘Medium’ District General Hospital and community services. • Approx. 4,200 staff, £250M pa budGet • Rural with Industrial Centre • Shared Health Informatics Service The NHS digital strategic landscape • The focus in digital planning has shifted from trusts to the local health community, Sustainability and Transformation Partnerships (STPs) leading to Integrated Care Systems (ICS) • The national agenda has changed from technology to ‘digitisation’ • The Wachter Report to NHS England endorsed this and led to 12 Trusts being appointed ‘Global Digitisation Exemplars (GDEs)’ attracting matched funding up to £10m • Trust-based systems are still critical in driving a paper-lite NHS agenda for the 2020’s • There is an increased awareness of CyberSecurity threats to the NHS Over the past 10 years the Trust has implemented and developed core mission-critical patient systems around Meditech (Acute) and SystmOne (Community).

CPs are medical management plans designed to standardize medical activities, reduce cost, optimize resource usage, and improve quality of service. However, most CPs are still paper-based and not fully integrated with Health Information Systems (HISs).
