CareReport

This resource represents a clinical document that summarizes the care provided to a patient during a specific encounter, episode, or period. It typically includes information such as patient details, reason for care, assessments, interventions, treatments, outcomes, and recommendations for ongoing management or follow-up.

Structure

Composition	C		Composition	There are no (further) constraints on this element Element id Composition Short description A set of resources composed into a single coherent clinical statement with clinical attestation Definition 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.). Comments While the focus of this specification is on patient-specific clinical statements, this resource can also apply to other healthcare-related statements such as study protocol designs, healthcare invoices and other activities that are not necessarily patient-specific or clinical. Data type Composition Constraints dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources `contained.contained.empty()` dom-3: 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: 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: If a resource is contained in another resource, it SHALL NOT have a security label `contained.meta.security.empty()` dom-6: A resource should have narrative for robust management text.`div`.exists() Mappings rim: Entity, Role, or Act,Document[classCode="DOC" and moodCode="EVN" and isNormalAct()] workflow: Event w5: infrastructure.documents cda: ClinicalDocument fhirdocumentreference: when described by DocumentReference
id	Σ	0..1	id	There are no (further) constraints on this element Element id Composition.id Short description Logical id of this artifact Definition The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. Comments Within the context of the FHIR RESTful interactions, the resource has an id except for cases like the create and conditional update. Otherwise, the use of the resouce id depends on the given use case. Data type id
meta	Σ	0..1	Meta	There are no (further) constraints on this element Element id Composition.meta Short description Metadata about the resource Definition The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource. Data type Meta Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())`
implicitRules	Σ ?!	0..1	uri	There are no (further) constraints on this element Element id Composition.implicitRules Short description A set of rules under which this content was created Definition A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. Comments Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc. Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())`
language		0..1	codeBinding	There are no (further) constraints on this element Element id Composition.language Short description Language of the resource content Definition The base language in which the resource is written. Comments Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute). Data type code Binding IETF language tag for a human language AllLanguages (required) Additional bindings CommonLanguages (starter) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())`
text	C	0..1	Narrative	There are no (further) constraints on this element Element id Composition.text Short description Text summary of the resource, for human interpretation Alternate names narrative, html, xhtml, display Definition A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety. Comments Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later. Data type Narrative Conditions The cardinality or value of this element may be affected by these constraints: dom-6 Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: Act.text?
contained	C	0..*	Resource	There are no (further) constraints on this element Element id Composition.contained Short description Contained, inline Resources Alternate names inline resources, anonymous resources, contained resources Definition These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning. Comments This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels. Data type Resource Conditions The cardinality or value of this element may be affected by these constraints: dom-2, dom-4, dom-3, dom-5 Mappings rim: N/A
extension	C	0..*	Extension	There are no (further) constraints on this element Element id Composition.extension Short description Additional content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. Data type Extension Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` ext-1: Must have either extensions or value[x], not both `extension.exists() != value.exists()` Mappings rim: N/A
modifierExtension	Σ ?! C	0..*	Extension	There are no (further) constraints on this element Element id Composition.modifierExtension Short description Extensions that cannot be ignored Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). Requirements Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. Comments There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

url	Σ	0..1	uri	There are no (further) constraints on this element Element id Composition.url Short description Canonical identifier for this Composition, represented as a URI (globally unique) Definition An absolute URI that is used to identify this Composition when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this Composition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the Composition is stored on different servers. Requirements Allows the Composition to be referenced by a single globally unique identifier. Comments Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version. Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings w5: FiveWs.identifier
identifier	Σ	1..*	Identifier	Element id Composition.identifier Short description Version-independent identifier for the Composition Definition A version-independent identifier for the Composition. This identifier stays constant as the composition is changed over time. Comments Similar to ClinicalDocument/setId in CDA. See discussion in resource definition for how these relate.

Requirements Allows users to make use of identifiers when the identifier system is not known. Comments This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known.

status	Σ ?!	1..1	codeBinding	There are no (further) constraints on this element Element id Composition.status Short description registered \| partial \| preliminary \| final \| amended \| corrected \| appended \| cancelled \| entered-in-error \| deprecated \| unknown Definition The workflow/clinical status of this composition. The status is a marker for the clinical standing of the document. Requirements Need to be able to mark interim, amended, or withdrawn compositions or documents. Comments If a composition is marked as withdrawn, the compositions/documents in the series, or data from the composition or document series, should never be displayed to a user without being clearly marked as untrustworthy. The flag "entered-in-error" is why this element is labeled as a modifier of other elements. Some reporting work flows require that the original narrative of a final document never be altered; instead, only new narrative can be added. The composition resource has no explicit status for explicitly noting whether this business rule is in effect. This would be handled by an extension if required.

Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Requirements The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all.

The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Comments Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach.

The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). Comments This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not).

identifier	Σ C	0..1	Identifier	There are no (further) constraints on this element Element id Composition.subject.identifier Short description Logical reference, when literal reference is not known Definition An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. Comments When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation\|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any). This element only allows for a single identifier. In the case where additional identifers are required, use the http://hl7.org/fhir/StructureDefinition/additionalIdentifier extension.

reference	Σ C	1..1	string	There are no (further) constraints on this element Element id Composition.author.reference Short description Literal reference, Relative, internal or absolute URL Definition A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Comments Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

type	Σ	0..1	uriBinding	There are no (further) constraints on this element Element id Composition.author.type Short description Type the reference refers to (e.g. "Patient") - must be a resource in resources Definition The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). Comments This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a known RESTful URL) or by resolving the target of the reference.

identifier	Σ C	0..1	Identifier	There are no (further) constraints on this element Element id Composition.author.identifier Short description Logical reference, when literal reference is not known Definition An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. Comments When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation\|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any). This element only allows for a single identifier. In the case where additional identifers are required, use the http://hl7.org/fhir/StructureDefinition/additionalIdentifier extension.

focus		0..0	Reference(Resource)	There are no (further) constraints on this element Element id Composition.section.focus Short description Who/what the section is about, when it is not about the subject of composition Definition The actual focus of the section when it is not the subject of the composition, but instead represents something or someone associated with the subject such as (for a patient subject) a spouse, parent, fetus, or donor. If not focus is specified, the focus is assumed to be focus of the parent section, or, for a section in the Composition itself, the subject of the composition. Sections with a focus SHALL only include resources where the logical subject (patient, subject, focus, etc.) matches the section focus, or the resources have no logical subject (few resources). Comments Typically, sections in a doument are about the subject of the document, whether that is a patient, or group of patients, location, or device, or whatever. For some kind of documents, some sections actually contain data about related entities. Typical examples are a section in a newborn discharge summary concerning the mother, or family history documents, with a section about each family member, though there are many other examples.

To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Requirements Important for presentation and rendering. Lists may be sorted to place more important information first or to group related entries. Comments Applications SHOULD render ordered lists in the order provided, but MAY allow users to re-order based on their own preferences as well. If there is no order specified, the order is unknown, though there may still be some order. Data type CodeableConcept Binding What order applies to the items in the entry.

reference	Σ C	0..1	string	There are no (further) constraints on this element Element id Composition.section.entry.reference Short description Literal reference, Relative, internal or absolute URL Definition A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. Comments Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

type	Σ	0..1	uriBinding	There are no (further) constraints on this element Element id Composition.section.entry.type Short description Type the reference refers to (e.g. "Patient") - must be a resource in resources Definition The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). Comments This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a known RESTful URL) or by resolving the target of the reference. Data type uri Binding Aa resource (or, for logical models, the URI of the logical model).

identifier	Σ C	0..1	Identifier	There are no (further) constraints on this element Element id Composition.section.entry.identifier Short description Logical reference, when literal reference is not known Definition An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference. Comments When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation\|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any). This element only allows for a single identifier. In the case where additional identifers are required, use the http://hl7.org/fhir/StructureDefinition/additionalIdentifier extension.

display	Σ C	0..1	string	There are no (further) constraints on this element Element id Composition.section.entry.display Short description Text alternative for the resource Definition Plain text narrative that identifies the resource in addition to the resource reference.

emptyReason	C	0..0	CodeableConceptBinding	There are no (further) constraints on this element Element id Composition.section.emptyReason Short description Why the section is empty Definition If the section is empty, why the list is empty. An empty section typically has some text explaining the empty reason. Requirements Allows capturing things like "none exist" or "not asked" which can be important for most lists. Comments The various reasons for an empty section make a significant interpretation to its interpretation. Note that this code is for use when the entire section content has been suppressed, and not for when individual items are omitted - implementers may consider using a text note or a flag on an entry in these cases. Data type CodeableConcept Binding If a section is empty, why it is empty.
