When developing simple reference sets, there are different methods which can be applied to determine what concepts to be included in the subset. The two overall approaches to defining the reference set members are manual enumeration and intensional definition.
Reference set development approaches
Requirements (recommendations?) for manual enumeration
Identifying reference set members by manual enumeration is useful when the number of members required is limited or when migrating from a well-specified domain. The source information may come from a variety of sources, such as:
- Subsets of concepts from other code systems
- Legacy codes (when migrating from a system that do not use SNOMED CT)
- Clinical guidelines and other knowledge resources
Additionally, manual enumeration is useful when the reference set should be stable over time....
