One of the main drivers for deploying SNOMED CT is to structure data and benefit from the ontology to gain clinical insights into patient data that may otherwise be unavailable in unstructured data. The use of maps of data already coded using local systems to SNOMED CT will help to move towards the rich analysis that SNOMED CT enables, as well as using maps to provide the step from SNOMED CT to national & international classifications for statistical reporting.
- Use maps from local code systems to SNOMED CT to enable ad hoc querying, reporting and analysis of legacy clinical data or for national or local reporting.
- Use maps to national and international classifications to enable analysis and reporting of data, including legacy and current data.
- Applications supporting data reporting, extraction and/or clinical decision support rules shall (where appropriate) use SNOMED CT’s defining relationships in the determination of the correct results or outcomes.
