DeviceMetric

Describes mandatory static properties that characterize a direct or derived, quantitative or qualitative biosignal measurement, setting, or calculation produced by a medical device component like glucometers or insulin pumps (for example; mg/dL, [iU], etc.)

The DeviceMetric resource describes mandatory static properties that characterize a direct or derived, quantitative or qualitative biosignal measurement, setting, or calculation produced by a medical device. The DeviceMetric resource can also be used to describe the non-static but highly relevant properties to the metric such as metric status, metric last calibration time and type, measurement mode, color, reference link to the parent DeviceComponent to where it belongs, and any capabilities that the metric offers (for example: setting the metric label).

This profile is most current version of the DeviceMetric resource which is used by several applications.

DeviceMetric resource has an element called identifer which has values mentioned as below.

"identifier": {
	"system": "http://roche.com/fhir/rdc/sid/devicemetric-identifier",
	"value": "2344-0"
}
- system is static
- value should be populated from DeviceMetric.type.coding.code

A diagram that depicts DeviceMetrics structure and relationships is showed below:

DeviceMetric (former version)

The DeviceMetric resource describes mandatory static properties that characterize a direct or derived, quantitative or qualitative biosignal measurement, setting, or calculation produced by a medical device. The DeviceMetric resource can also be used to describe the non-static but highly relevant properties to the metric such as metric status, metric last calibration time and type, measurement mode, color, reference link to the parent DeviceComponent to where it belongs, and any capabilities that the metric offers (for example: setting the metric label).

There are two related resources.

• Device - The physical device that this DeviceMetric belongs to.
• DeviceComponent - The DeviceComponent that this DeviceMetric is part of. This can be a DeviceComponent of any kind like a VirtualMedicalDevice, a MedicalDeviceSystem, or a Channel.

This profile is created to support former version of the DeviceMetric resource which is used by GreenDot,ConnectApp,OBT,uDTC (ACSPIX to FHIR).

The former DeviceMetric resource has an element called identifer which has values mentioned as below.

"identifier": {
    "system": "urn:ietf:rfc:3986",
    "value": "urn:uuid:22efbe46-7c30-4397-8f07-23898f082a97"
}
- system is static
- value is urn:uuid:<UID generated number>

DeviceMetric resource generated with identifier element will be based on this profile: https://simplifier.net/RDC/dm-device-metric-uuid
