Mapping from IEEE 11073-10201 DIM to FHIR

Within the context of the ISO/IEEE 11073 Point-of-care medical device communication standards, ISO/IEEE 11073-10201 provides an abstract, object-oriented domain information model (DIM) that defines a hierarchical model for structuring medical device data as well as events and services.

DIM Object Classes

Most object classes in ISO/IEEE 11073 DIM can be mapped to FHIR resources as outlined in the following table.

DIM Object Attributes

Please refer to the Mappings tab of each profile page for mapping ISO/IEEE 11073 DIM object attributes to FHIR resource elements.

Mapping Details

Measurement Status

Observed values in ISO/IEEE 11073 DIM include a bit field that indicates measurement status. FHIR Observations do not have a single element for this purpose. Instead there is security metadata, dataAbsentReason for missing values, and interpretation to report significance of a result.
Measurement status information is mapped to Resource.meta.security, Observation.dataAbsentReason or Observation.component.dataAbsentReason, and Observation.interpretation or Observation.component.interpretation elements. The interpretation value set binding is extended to add relevant codes from the Measurement status codes defined in this implementation guide.

Note that dataAbsentReason and interpretation are mutually exclusive: dataAbsentReason shall only be present if there is no observation value, whereas interpretation adds relevant information about an existing observation value.
