Device Definition

$10 / year

Device is a type of a manufactured item that is used in the provision of healthcare without being substantially changed through that activity. The device may be a medical or non-medical device and this dataset has its definition.

Complexity

This resource is an administrative resource that tracks individual instances of a device and their location. It is referenced by other resources for recording which device performed an action such as a procedure or an observation, referenced when prescribing and dispensing devices for patient use or for ordering supplies, and used to record and transmit Unique Device Identifier (UDI) information about a device such as a patient’s implant.

These are the device related resources

– Device (this resource)
– DeviceDefinition – Describes a “kind” of device – not a physical instance, cut a “catalog entry” where a device is defined by the manufacturer, reseller, or regulator.
– DeviceMetric – Describes a measurement, calculation or setting capability of a medical device.

In FHIR, the “Device” is the “administrative” resource for the device (it does not change much and has manufacturer information etc.), whereas the Device Component and Device Metric (which is really a kind of Device Component) model the physical part, including operation status and is much more volatile. The physical composition of a Device is represented by the Devices pointing to their “parent”.

Devices differ from medications because they are not “used up” – they remain active in a patient in an ongoing fashion. However, the specific boundary between medications and devices is defined at the implementation level and this standard does not enforce a boundary with the exception of devices that are implanted in a patient. The Medication resource should not be used to represent implanted devices.

Fast Healthcare Interoperability Resources (FHIR) is a draft standard describing data formats and elements (known as “resources”) and an application programming interface (API) for exchanging electronic health records. The standard was created by the Health Level Seven International (HL7) health-care standards organization.

Its goal is to facilitate interoperation between legacy healthcare systems, to make it easy to provide healthcare information to healthcare providers and individuals on a wide variety of devices from computers to tablets to cell phones, and to allow third-party application developers to provide medical applications which can be easily integrated into existing systems.

FHIR provides an alternative to document-centric approaches by directly exposing discrete data elements as services. For example, basic elements of healthcare like patients, admissions, diagnostic reports and medications can each be retrieved and manipulated via their own resource URLs (Uniform Resource Locators). FHIR was supported at an American Medical Informatics Association meeting by many EHR (Electronic Health Record) vendors which value its open and extensible nature.

NameDescriptionTypeConstraints
Concept_NameName of the concept in the FHIR structurestringrequired : 1
Computer_Ready_NameA Computer-ready name (e.g. a token) that identifies the structure - suitable for code generation. Note that this name (and other names relevant for code generation, including element & slice names, codes etc) may collide with reserved words in the relevant target language, and code generators will need to handle this.string-
TypeThe type the structure describes.string-
Dollar_RefThe Dollar_Ref ($ref) string value contains a Uniform Resource Identifier (URI) which identifies the location of the JSON (JavaScript Object Notation) value being referenced.string-
DescriptionA free text natural language description of the structure and its usestring-
ItemsThe value of the keyword should be an object or an array of objects. If the keyword value is an object, then for the data array to be valid each item of the array should be valid according to the schema in this value.string-
EnumThe enum is used to restrict a value to a fixed set of values. It must be an array with at least one element, where each element is unique.string-
RequiredThe value of the keyword should be an array of unique strings. The data object to be valid should contain all properties with names equal to the elements in the keyword value.string-
ConstThe value of this keyword can be anything. The data is valid if it is deeply equal to the value of the keyword.string-
Concept NameComputer Ready NameTypeDollar RefDescriptionItemsEnumRequiredConst
DeviceDefinition_Capabilityid#/definitions/stringUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
DeviceDefinition_CapabilityextensionarrayMay be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension there is a set of requirements that SHALL be met as part of the definition of the extension.{'$ref': '#/definitions/Extension'}
DeviceDefinition_CapabilitymodifierExtensionarrayMay be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 can 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).{'$ref': '#/definitions/Extension'}
DeviceDefinition_Capabilitytype#/definitions/CodeableConceptThe type of capability - whether it is a physical attribute a customization needed. For exampl e "water ingress protection".
