StructureDefinition UKCore-Condition
For detailing any Condition related information about the proband/consultands within a test order.
It is expected that the information used to populate this resource SHOULD be sourced from the requesters EHR system. As such, there is no limit on the amount of detail that can be provided, though at a minimum the code and subject fields SHOULD be populated.
It is also highly preferred if the verificationStatus, onsetDateTime, recordedDate, recorded and abatementDateTime are populated if applicable/known.
The primary condition, being tested for SHOULD be referenced via ServiceRequest.reasonReference, additional relevant conditions SHOULD be referenced via ServiceRequest.supportingInfo.

UKCoreCondition (Condition) | I | Condition | There are no (further) constraints on this element Element idCondition Detailed information about conditions, problems or diagnoses DefinitionA clinical condition, problem, diagnosis, or other event, situation, issue, or clinical concept that has risen to a level of concern.
| |
id | Σ | 0..1 | string | There are no (further) constraints on this element Element idCondition.id Logical id of this artifact DefinitionThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. The only time that a resource does not have an id is when it is being submitted to the server using a create operation. |
meta | Σ | 0..1 | Meta | There are no (further) constraints on this element Element idCondition.meta Metadata about the resource DefinitionThe 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.
|
implicitRules | Σ ?! | 0..1 | uri | There are no (further) constraints on this element Element idCondition.implicitRules A set of rules under which this content was created DefinitionA 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. 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 it's narrative along with other profiles, value sets, etc.
|
language | 0..1 | codeBinding | There are no (further) constraints on this element Element idCondition.language Language of the resource content DefinitionThe base language in which the resource is written. 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). A human language.
| |
text | 0..1 | Narrative | There are no (further) constraints on this element Element idCondition.text Text summary of the resource, for human interpretation Alternate namesnarrative, html, xhtml, display DefinitionA 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. Contained resources do not have 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.
| |
contained | 0..* | Resource | There are no (further) constraints on this element Element idCondition.contained Contained, inline Resources Alternate namesinline resources, anonymous resources, contained resources DefinitionThese resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope. 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.
| |
extension | I | 0..* | Extension | There are no (further) constraints on this element Element idCondition.extension Additional content defined by implementations Alternate namesextensions, user content DefinitionMay 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 manageable, 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. 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.

bodyStructureR6 | I | 0..1 | Extension(Reference(BodyStructure)) | Element idCondition.extension:bodyStructureR6 An extension to replicate the changes within R6 to support adding a reference to the body part affected by the diagnosed condition. Alternate namesextensions, user content DefinitionOptional Extension Element - found in all resources. 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.

modifierExtension | ?! I | 0..* | Extension | There are no (further) constraints on this element Element idCondition.modifierExtension Extensions that cannot be ignored Alternate namesextensions, user content DefinitionMay 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 manageable, 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). 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. 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.

|
identifier | Σ | 0..* | Identifier | There are no (further) constraints on this element Element idCondition.identifier External Ids for this condition DefinitionBusiness identifiers assigned to this condition by the performer or other systems which remain constant as the resource is updated and propagates from server to server. Allows identification of the condition as it is known by various participating systems and in a way that remains consistent across servers. This is a business identifier, not a resource identifier (see discussion). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number.
|
clinicalStatus | S Σ ?! I | 0..1 | CodeableConceptBinding | Element idCondition.clinicalStatus The clinical status of the condition. DefinitionThe clinical status of the condition. The data type is CodeableConcept because clinicalStatus has some clinical judgment involved, such that there might need to be more specificity than the required FHIR value set allows. For example, a SNOMED coding might allow for additional specificity. The clinical status of the condition or diagnosis.
|
verificationStatus | S Σ ?! I | 0..1 | CodeableConceptBinding | Element idCondition.verificationStatus The verification status to support the clinical status of the condition. DefinitionThe verification status to support the clinical status of the condition. verificationStatus is not required. For example, when a patient has abdominal pain in the ED, there is not likely going to be a verification status. The data type is CodeableConcept because verificationStatus has some clinical judgment involved, such that there might need to be more specificity than the required FHIR value set allows. For example, a SNOMED coding might allow for additional specificity. The verification status to support or decline the clinical status of the condition or diagnosis.
|
category | 0..* | CodeableConceptBinding | Element idCondition.category problem-list-item | encounter-diagnosis DefinitionA category assigned to the condition. The categorization is often highly contextual and may appear poorly differentiated or not very useful in other contexts. A ValueSet to identify the category of a condition.
| |
severity | S | 0..1 | CodeableConceptBinding | Element idCondition.severity A subjective assessment of the severity of the condition as evaluated by the clinician. DefinitionA subjective assessment of the severity of the condition as evaluated by the clinician. Coding of the severity with a terminology is preferred, where possible. A subjective assessment of the severity of the condition as evaluated by the clinician.
|
code | S Σ | 0..1 | CodeableConceptBinding | Element idCondition.code Identification of the condition, problem or diagnosis. Alternate namestype DefinitionIdentification of the condition, problem or diagnosis. 0..1 to account for primarily narrative only resources. Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination. A code from the SNOMED Clinical Terminology UK with the expression (<404684003 |Clinical finding| OR <413350009 |Finding with explicit context| OR <272379006 |Event|).
|
bodySite | Σ | 0..* | CodeableConceptBinding | Element idCondition.bodySite Anatomical location, if relevant DefinitionThe anatomical location where this condition manifests itself. Only used if not implicit in code found in Condition.code. If the use case requires attributes from the BodySite resource (e.g. to identify and track separately) then use the standard extension bodySite. May be a summary code, or a reference to a very precise definition of the location, or both. Codes describing anatomical locations. May include laterality.
|
subject | S Σ I | 1..1 | Reference(Patient | Group) | Element idCondition.subject Indicates the patient or group who the condition record is associated with. Alternate namespatient DefinitionIndicates the patient or group who the condition record is associated with. Group is typically used for veterinary or public health use cases. References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.
|
encounter | Σ I | 0..1 | Reference(Encounter) | There are no (further) constraints on this element Element idCondition.encounter Encounter created as part of DefinitionThe Encounter during which this Condition was created or to which the creation of this record is tightly associated. This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter. This record indicates the encounter this particular record is associated with. In the case of a "new" diagnosis reflecting ongoing/revised information about the condition, this might be distinct from the first encounter in which the underlying condition was first "known".
|
onset[x] | Σ | 0..1 | There are no (further) constraints on this element Element idCondition.onset[x] Estimated or actual date, date-time, or age DefinitionEstimated or actual date or date-time the condition began, in the opinion of the clinician. Age is generally used when the patient reports an age at which the Condition began to occur.

abatement[x] | I | 0..1 | There are no (further) constraints on this element Element idCondition.abatement[x] When in resolution/remission DefinitionThe date or estimated date that the condition resolved or went into remission. This is called "abatement" because of the many overloaded connotations associated with "remission" or "resolution" - Conditions are never really resolved, but they can abate. There is no explicit distinction between resolution and remission because in many cases the distinction is not clear. Age is generally used when the patient reports an age at which the Condition abated. If there is no abatement element, it is unknown whether the condition has resolved or entered remission; applications and users should generally assume that the condition is still valid. When abatementString exists, it implies the condition is abated.
