## Resource Profile: SGHI Composition

Official URL: https://fhir.slade360.co.ke/fhir/StructureDefinition/composition | Version: 0.1.0
Draft as of 2026-04-27 | Computable Name: SGHIComposition

A set of healthcare-related information that is assembled together into a single logical package that provides a single coherent statement of meaning, establishes its own context and that has clinical attestation with regard to who is making the statement. A Composition defines the structure and narrative content necessary for a document. However, a Composition alone does not constitute a document. Rather, the Composition must be the first entry in a Bundle where Bundle.type=document, and any other resources referenced from Composition must be included as subsequent entries in the Bundle (for example Patient, Practitioner, Encounter, etc.).

#### Constraints

Id | Grade | Path(s) | Description | Expression
cmp-1 | error | Composition.section | A section must contain at least one of text, entries, or sub-sections | `text.exists() or entry.exists() or section.exists()`
cmp-2 | error | Composition.section | A section can only have an emptyReason if it is empty | `emptyReason.empty() or entry.empty()`
dom-2 | error | Composition | If the resource is contained in another resource, it SHALL NOT contain nested Resources | `contained.contained.empty()`
dom-3 | error | Composition | If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource | `contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().ofType(canonical) | %resource.descendants().ofType(uri) | %resource.descendants().ofType(url))) or descendants().where(reference = '#').exists() or descendants().where(ofType(canonical) = '#').exists() or descendants().where(ofType(canonical) = '#').exists()).not()).trace('unmatched', id).empty()`
dom-4 | error | Composition | If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated | `contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()`
dom-5 | error | Composition | If a resource is contained in another resource, it SHALL NOT have a security label | `contained.meta.security.empty()`
dom-6 | best practice | Composition | A resource should have narrative for robust management | `text.`div`.exists()`
ele-1 | error | **ALL** elements | All FHIR elements must have a @value or children | `hasValue() or (children().count() > id.count())`
ext-1 | error | **ALL** extensions | Must have either extensions or value[x], not both | `extension.exists() != value.exists()`
