SNOMED CT reference sets provide a standard way of representing a set of references to SNOMED CT components. Reference sets are used to customize the terminology to meet a wide range of practical requirements, including constraining a search to a specific subset of SNOMED CT, or performing a map from a local code system to SNOMED CT.
This tutorial provides an introduction to SNOMED CT reference sets, and explains the purpose and design of a range of different types of reference sets. The reference set development process, and implementation considerations are also explored.
After attending this tutorial, the participant should be able to:
- Explain the difference between a subset, a value set, and a references set
- Describe the purposes for which reference sets may be used
- Summarize the different types of reference sets and provide example use cases for each
- Describe the phases of reference set development and implementation
