SNOMED CT is a standardized and multilingual clinical terminology used by clinicians and other health care providers to record and share health information. As the most comprehensive terminology in the world, SNOMED CT contains over 300,000 active clinical concepts, each representing a unique clinical meaning. These concepts are organized into hierarchies such as 404684003 |Clinical finding| , 71388002 |Procedure| , 123037004 |Body structure| and 373873005 |Pharmaceutical / biologic product|.
SNOMED CT is increasingly being used in clinical decision support (CDS) systems to support healthcare providers in making well informed clinical decisions. SNOMED CT's polyhierarchy, defining relationships and concept model are just some of the terminology's features that help to link patient records to the appropriate guidance, clinical knowledge and decision rules.
The guide Data Analytics with SNOMED CT explained how SNOMED CT may be used to support data analytics, and how integrating clinical records with decision support tools can improve the care provided to individual patients by guiding safe, appropriate and effective patient care.
The purpose of this guide is to review the approaches, tools and techniques used to implement clinical decision support with SNOMED CT, and to share developing practice in this area. It is anticipated that this guide will benefit Members, vendors and users of SNOMED CT by promoting a greater awareness of how SNOMED CT has been and can be used to enhance clinical decision support implementations.
This guide introduces the key components of clinical decision support systems, explores ways in which SNOMED CT can be used to enhance the capabilities within each of these components, and presents some case studies in which SNOMED CT has been used to support clinical decision support. The guide focuses on CDS systems that use a combination of SNOMED CT encoded knowledge artifacts (e.g. CDS rules and guidelines) and SNOMED CT encoded electronic health records. However, using SNOMED CT to enhance non-SNOMED CT enabled CDS and EHR systems is also considered.
The target audience of this guide includes:
