10. SNOMED CT • The chosen terminology for the NHS England Use of Synonyms helps cater for different expressions with the same meaning

11. Terminology / Classification Classifications are intended for population statistics and analysis.  Terminologies are designed to be used by clinicians in their recording of data in a patient record. Maps between SNOMED CT and the classifications are provided as part of the national product set to support classification coding.

32. Subsets What is a SUBSET? • SNOMED CT is extensive – it is supporting a common vocabulary for all healthcare specialisms, and all healthcare professionals, as well as keeping up to date with current practice • A subset is ‘smaller set of SNOMED CT ‘ that meets a particular requirement • A SNOMED CT subset can be a group of concepts, descriptions or relationships chosen for relevance under certain conditions or in certain contexts

33. Subsets Why SUBSETS? • It is often desirable to constrain the SNOMED CT concepts available to a subset, say to help faster data entry – so for example, all possible performed procedures in a radiology department or a theatre department

34. Subsets HOW APPLICATIONS USE SUBSETS • Supports easier navigation • Can be used to limit to specific SNOMED CT codes • Can act like a ‘favourites’ for the end user • Can be used nationally or locally –synchronised national releases • Access to subsets may be role based

35. Current Subsets Examples

36. Examples of use and benefits

37. The World Changes…

38. Summary Care Record • Patient summary record • Contains allergies, adverse reactions, medications (current repeat, discontinued repeat, acute). Additional information with patients consent such as current diagnoses e.g. diabetes, asthma • This SCR clinical data is stored using SNOMED CT • Provides consistent recording and semantic interoperability across a mixed coding domain

39. Choose and Book GP produces referral letter as template or dictation Consultant reviews and accepts referral GP and patient decide that referral is appropriate, and creates appointment request Patient makes choice of provider with information support Appt. booked by the patient via internet or phone, or in the practice
