1. AdverseEvent
Definition | An event (i.e. any change to current patient status) that may be related to unintended effects on a patient or research participant. The unintended effects may require additional monitoring, treatment, hospitalization, or may result in death. The AdverseEvent resource also extends to potential or avoided events that could have had such effects. There are two major domains where the AdverseEvent resource is expected to be used. One is in clinical care reported adverse events and the other is in reporting adverse events in clinical research trial management. Adverse events can be reported by healthcare providers, patients, caregivers or by medical products manufacturers. Given the differences between these two concepts, we recommend consulting the domain specific implementation guides when implementing the AdverseEvent Resource. The implementation guides include specific extensions, value sets and constraints.
Control | 0..*
Summary | false
Alternate Names | AE
Invariants | Defined on this element 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())
2. AdverseEvent.implicitRules
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.
Control | 0..1
Type | uri
Is Modifier | true
Summary | true
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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
3. AdverseEvent.contained
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.
Control | 0..* This element is affected by the following invariants: dom-2, dom-4, dom-3, dom-5
Type | Resource
Summary | false
Alternate Names | inline resources, anonymous resources, contained resources
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.
4. AdverseEvent.modifierExtension
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).
Control | 0..*
Type | Extension
Is Modifier | true
Summary | true
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.
Alternate Names | extensions, user content
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.
Invariants | Defined on this element 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())
5. AdverseEvent.status
Definition | The current state of the adverse event or potential adverse event.
Control | 1..1
Binding | The codes SHALL be taken from AdverseEventStatus Codes identifying the lifecycle stage of an event.
Type | code
Is Modifier | true
Summary | true
Comments | This is not the reporting of the event to any regulatory or quality organization. This is not the outcome of the patient's condition.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. AdverseEvent.actuality
Definition | Whether the event actually happened or was a near miss. Note that this is independent of whether anyone was affected or harmed or how severely.
Control | 1..1
Binding | The codes SHALL be taken from AdverseEventActuality Overall nature of the adverse event, e.g. real or potential.
Type | code
Is Modifier | true
Summary | true
Comments | AllergyIntolerance should be used for the initial capture or recording of the individual's propensity to an adverse reaction to a substance. If an AllergyIntolerance does not exist, then an adverse reaction should be recorded as an AllergyIntolerance. If an AllergyIntolerance does exist and the substance was given, then an adverse reaction should be recorded as an AdverseEvent due to the aberrant workflow.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. AdverseEvent.subject
Definition | This subject or group impacted by the event.
Control | 1..1
Type | Reference(Patient|Group|Practitioner|RelatedPerson|ResearchSubject)
Summary | true
Requirements | Allows for exposure of biohazard (such as legionella) to a group of individuals in a hospital.
Alternate Names | patient
Comments | If AdverseEvent.resultingEffect differs among members of the group, then use Patient as the subject.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
8. AdverseEvent.seriousness
Definition | Assessment whether this event, or averted event, was of clinical importance.
Control | 0..01
Binding | For example codes, see AdverseEventSeriousness Overall seriousness of this event for the patient.
Type | CodeableConcept
Summary | true
Comments | Using an example, a rash can have an AdverseEvent.resultingEffect.severity = severe, yet an AdverseEvent.seriousness = non-serious. Alternatively, a medication given with the wrong dose (chemotherapy given with too low of a dose) can have an AdverseEvent.resultingEffect.severity = mild, yet an adverseEvent.seriousness = serious. Another example would be a beta blocker clinical trial where patients with asthma should be excluded, yet a patient with asthma was included and had an asthmatic episode where AdverseEvent.resultingEffect.severity = mild, yet an adverseEvent.seriousness = serious.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
9. AdverseEvent.recorder
Definition | Information on who recorded the adverse event. May be the patient or a practitioner.
Control | 0..1

1. AdverseEvent
Definition | An event (i.e. any change to current patient status) that may be related to unintended effects on a patient or research participant. The unintended effects may require additional monitoring, treatment, hospitalization, or may result in death. The AdverseEvent resource also extends to potential or avoided events that could have had such effects. There are two major domains where the AdverseEvent resource is expected to be used.

The implementation guides include specific extensions, value sets and constraints.
Control | 0..*
Summary | false
Alternate Names | AE
2. AdverseEvent.id
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Control | 0..1
Type | id
Summary | true
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.
3. AdverseEvent.meta
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.
Control | 0..1
Type | Meta
Summary | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
4. AdverseEvent.implicitRules
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.
Control | 0..1

Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
5. AdverseEvent.language
Definition | The base language in which the resource is written.
Control | 0..1
Binding | The codes SHALL be taken from AllLanguages IETF language tag for a human languag
Type | code
Summary | false
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).
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. AdverseEvent.text
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.
Control | 0..1 This element is affected by the following invariants: dom-6
Type | Narrative
Summary | false
Alternate Names | narrative, html, xhtml, display
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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. AdverseEvent.contained
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.
Control | 0..* This element is affected by the following invariants: dom-2, dom-4, dom-3, dom-5
Type | Resource
Summary | false
Alternate Names | inline resources, anonymous resources, contained resources
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.
8. AdverseEvent.extension
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.

9. AdverseEvent.modifierExtension
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.

10. AdverseEvent.identifier
Definition | Business identifiers assigned to this adverse event by the performer or other systems which remain constant as the resource is updated and propagates from server to server.
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*
Type | Identifier
Summary | true
Requirements | Allows identification of the adverse event as it is known by various participating systems and in a way that remains consistent across servers.
Comments | 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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))

16. AdverseEvent.encounter
Definition | The Encounter associated with the start of the AdverseEvent.
Control | 0..1
Type | Reference(Encounter)
Summary | true
Comments | 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. For example, if a medication administration was considered an adverse event because it resulted in a rash, then the encounter when the medication administration was given is the associated encounter. If the patient reports the AdverseEvent during a second encounter, that second encounter is not the associated encounter.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
17. AdverseEvent.occurrence[x]
