DeviceUseStatement

A record of a device being used by a patient where the record is the result of a report from the patient or another clinician.

Schema

Properties

Name	Required	Type	Description
identifier		Identifier[]	External identifier for this record Details An external identifier for this statement such as an IRI.
basedOn		Reference<ServiceRequest>[]	Fulfills plan, proposal or order Details A plan, proposal or order that is fulfilled in whole or in part by this DeviceUseStatement.
status	✓	code	active | completed | entered-in-error + Details A code representing the patient or other source's judgment about the state of the device used that this statement is about. Generally this will be active or completed. DeviceUseStatment is a statement at a point in time. The status is only representative at the point when it was asserted. The value set for contains codes that assert the status of the use by the patient (for example, stopped or on hold) as well as codes that assert the status of the resource itself (for example, entered in error). This element is labeled as a modifier because the status contains the codes that mark the statement as not currently valid.
subject	✓	Reference<Patient | Group>	Patient using device Details The patient who used the device.
derivedFrom		Reference< ServiceRequest | Procedure | Claim | Observation | QuestionnaireResponse | DocumentReference >[]	Supporting information Details Allows linking the DeviceUseStatement to the underlying Request, or to other information that supports or is used to derive the DeviceUseStatement. The most common use cases for deriving a DeviceUseStatement comes from creating it from a request or from an observation or a claim. it should be noted that the amount of information that is available varies from the type resource that you derive the DeviceUseStatement from.
timing[x]		Timing, Period, dateTime	How often the device was used Details How often the device was used.
recordedOn		dateTime	When statement was recorded Details The time at which the statement was made/recorded.
source		Reference< Patient | Practitioner | PractitionerRole | RelatedPerson >	Who made the statement Details Who reported the device was being used by the patient.
device	✓	Reference<Device>	Reference to device used Details The details of the device used.
reasonCode		CodeableConcept[]	Why device was used Details Reason or justification for the use of the device.
reasonReference		Reference< Condition | Observation | DiagnosticReport | DocumentReference | Media >[]	Why was DeviceUseStatement performed? Details Indicates another resource whose existence justifies this DeviceUseStatement.
bodySite		CodeableConcept	Target body site Details Indicates the anotomic location on the subject's body where the device was used ( i.e. the target).
note		Annotation[]	Addition details (comments, instructions) Details Details about the device statement that were not represented at all or sufficiently in one of the attributes provided in a class. These may include for example a comment, an instruction, or a note associated with the statement.

Inherited Properties

Name	Required	Type	Description
id		string	Logical id of this artifact Details The 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		Meta	Metadata about the resource Details 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.
implicitRules		uri	A set of rules under which this content was created Details 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. 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		code	Language of the resource content Details The 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).
text		Narrative	Text summary of the resource, for human interpretation Details 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. 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		Resource[]	Contained, inline Resources Details These 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		Extension[]	Additional content defined by implementations Details 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 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.
modifierExtension		Extension[]	Extensions that cannot be ignored Details 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 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). 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.

Usage

These resources have not yet undergone proper review by PC, CQI, CDS, and OO. At this time, they are to be considered only as draft resource proposals for potential submission.

This resource is an event resource from a FHIR workflow perspective - see Workflow. It is the intent of the Orders and Observation Workgroup to align this resource with the workflow pattern for event resources.

This resource records the use of a healthcare-related device by a patient. The record is the result of a report of use by the patient, another provider or a related person. The resource can be used to note the use of an assistive device such as a wheelchair or hearing aid, a contraceptive such an intra-uterine device, or other implanted devices such as a pacemaker.

Relationships

This resource is different from DeviceRequest which records a request to use the device. This also is distinct from the Procedure resource which may describe the implantation or explantation of a device.
