4) How is SNOMED CT used?
SNOMED CT itself is only a part of the solution to addressing the requirements for effective electronic health records. A terminology on its own 'does nothing'. To benefit from use of a clinical terminology, it must be implemented and used as part of an application.
The design of the software application in which it is used, and the objectives and motivation of its users, are key factors in determining success.
SNOMED CT is critical for clinical documentation, as it supports the representation of detailed clinical information in a way that can be processed automatically.
Realization of the capability of SNOMED CT to support clinical information and meaning based retrieval requires careful consideration of the actual setting, in terms of scope of use, record structure, data entry, data retrieval and communication.
