The circumstances that form the setting in which a concept can be appropriately interpreted.
Notes
- Clear recording and appropriate interpretation of context is essential for safe use and accurate analysis of electronic health records.
- The context in which a concept is used can be represented in various ways. Some of the possible representation are shown in the examples section below.
- Appropriate interpretation of different representations of context can be facilitated by terminology binding techniques that resolve multiple models of use into a common model of meaning.
Examples
- A disease such as "asthma" might be referred to in various contexts.
- A current presenting problem needing treatment
- A past history recorded during assessment for treatment of another condition
- A family history recorded routinely during a consultation
- Family history of asthma can be recorded using SNOMED CT in several ways three of which are illustrated here.
Use of a single concept from the situation with explicit context domain:
Application of a context wrapper to the concept 195967001 | Asthma (disorder)| :
Use of features of an electronic health record model, such as separate record sections for information with different contexts.
- Based on the definitions of these concepts, a description logic classifier will infer that first two representations above have precisely the same meaning. The third representation can be similarly resolved if the "Family History Record Section" has a model or meaning binding to the 57177007 | Family history with explicit context (situation)| wrapper.
