A clinical registry is a database that gathers together patient information focusing on a specific diagnosis or clinical definition. The database is then used to help to improve and monitor the quality of patient care. The structure of computerised databases supports the sharing of data between registries. SNOMED CT supports both the data sharing interoperability requirement, but in addition also provides an analytical framework to provide greater insight into the data and linkages between data items. The session will explore real-world experiences of using SNOMED CT to support these purposes, and hopes to generate a broader discussion on the uptake of SNOMED CT to support this important use case.
