8.17 Resource Substance - Content

Orders and Observations

Work Group

Maturity Level: 2

Trial Use

Security Category: Business

Compartments: Not linked to any defined compartments

A homogeneous material with a definite composition.

8.17.1 Scope and Usage

This resource allows for a material to be represented. The resource can be used to represent either a kind of a substance - e.g. a formulation commonly used for treating patients, or it can be used to describe a particular package of a known substance (e.g. bottle, jar, packet).

The composition of the material can be specified in terms of a mix of other materials, including with precise amounts if required.

8.17.2 Boundaries and Relationships

A medication is a substance that is packaged and used as an administered medication. The medication resource uses the substance resource to represent the actual ingredients of a medication.

8.17.3 References

This resource is referenced by ActivityDefinition, AdverseEvent, BiologicallyDerivedProduct, CarePlan, CatalogEntry, ChargeItem, ChargeItemDefinition, ClinicalUseIssue, Contract, Group, Ingredient, Medication, Specimen, SpecimenDefinition, itself, SubstanceDefinition, SupplyDelivery and SupplyRequest.

This resource does not implement any patterns.
