Resource Profile: ObservationNews2Lite

Introduction

The ObservationNews2Lite profile represents the Assessment scale NEWS2 and is a profile created from the resource Observation. The NEWS2 is a scale for the severity of a patients condition. The NEWS2 score is calculated by the vital signs of a patient.

Intended Use

The ObservationNews2Lite is used for communicating the severity of a patients condition by sending the calculated score in observation.value. The score should be between 0 and 20. The News2 profile should also contain references for all vital signs used to calculate the score. It is mandatory to send all the vital signs. The score(observation.value) is optional. In COSMIC the NEWS2 score is mapped to the internal archetype for NEWS2.

The API can be used to create, invalidate/remove and read patient NEWS2 information from/to COSMIC.

Create NEWS2

• To create data using this API, the user should be a healthcare professional with a specified HSA ID. The healthcare professional should have their assignment, and be connected, to the specified care unit. The care unit should also be specified with a HSA ID.
• The intended use is in first hand that the API is used within the same caregiver. The user and the specified care unit should exist in COSMIC as well as in the external system.

Invalidate NEWS2

• If the external system is considered the master system of the information, it should be possible through the API to invalidate/delete the data in COSMIC, if it is invalidated/deleted in the master system.
• Invalidation of data should be done by a healthcare professional with a specified HSA ID. The healthcare professional should have their assignment, and be connected, to the specified unit. The Unit should also be specified with a HSA ID. This is for traceability purposes and should be for the log.

Read NEWS2

• The intended use for reading data with this API is in first hand that the API is applied for direct access and should not be used to transfer data between caregivers. If it should be used for "data copying" between caregivers, patient consent must be handled outside the API.

Constraints

Id	Grade	Path(s)	Details	Requirements
dom-2	error	Observation	If the resource is contained in another resource, it SHALL NOT contain nested Resources : contained.contained.empty()
dom-3	error	Observation	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().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()

dom-6	best practice	Observation	A resource should have narrative for robust management : text.`div`.exists()
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())
