SNOMED CT Initial Translation package Alpha Release Notes - April 2017

Background

SNOMED CT International release is published in US English, with an additional South American Spanish translation available. The initial translation sets are aimed at increasing the adoption of SNOMED CT globally and provides a set of 6,300 concepts in French, German, Simplified Chinese and Japanese. The aim of the translations are to provide access to clinicians and end-users to SNOMED CT descriptions (terms) in their own language. This approach will support the engagement of clinicians and clinical groups within the selected countries by allowing discussions based on the future format of SNOMED CT in EHR's within those countries.

Introduction

The minimum core set (initial set) describes a set of terms identified as commonly used and high usage terms by existing SNOMED CT users. The set is not intended to be a comprehensive list, but rather to provide a defined list of common terms that will support new users of SNOMED CT. The approximate size of the minimum core set is approximately 6,500 concepts.

Implementation

The initial translation sets are provided in SNOMED CT Refset format, and contain conceptId's and descriptions only. The sets are required to be implemented alongside the SNOMED CT release, with the refset providing the preferred terms for display within a system. The refsets cannot be implemented in isolation from a SNOMED CT release.

The refsets are provided with alignment to the latest SNOMED CT International Release.
