Scope and usage

KLToolsCareBloodPressure is an observation of blood pressure. Its intended use is Danish municipalities.

Test-setup

The blood pressure of the citizen is meassured using an appropriate device (typically but not always meassuring the pressure in a. brachialis in the upper arm).

Citizen performance

The citizen is standing, sitting or lying still, and is calm throughout the meassurement.

Using the model

The Observation.code is fixed to a single LOINC code 85354-9 ‘Blood pressure panel with all children optional’ and a SNOMED CT code for Blood pressure 75367002 ‘Blood pressure (observable entity)’.

The result of the blood pressure observation is a systolic and diastolic blood pressure. They are each represented as an Observation.component.

The systolic blood pressure component have an observation code: Observation.component.code. This code is bound to the Loinc code: 8480-6 ‘Systolic blood pressure’ and a ValueSet with different SNOMED CT codes for systolic blood pressure. The SNOMED CT code 271649006 ‘Systolic blood pressure’ is appropriate for most use cases. However, the precision of the data can be improved by choosing one of the SNOMED CT codes that specify the position of the subject. The result of a systolic blood pressure meassurement is represented in Observation.component.valueQuantity. It should contain a positive decimal, and use the UCUM unit for mmHg.

The diastolic blood pressure component have an observation code: Observation.component.code. This code is bound to the Loinc code: 8462-4 ‘Diastolic blood pressure’ and a ValueSet with different SNOMED CT codes for diastolic blood pressure. The SNOMED CT code 271650006 ‘Diastolic blood pressure’ is appropriate for most use cases. However, the precision of the data can be improved by choosing one of the SNOMED CT codes that specify the position of the subject. The result of a diastolic blood pressure meassurement is represented in Observation.component.valueQuantity. It should contain a positive decimal, and use the UCUM unit for mmHg.

Observation.method holds information about whether the “Test-setup” and “Citizen performance” have met the procedure-standards as described by KL, which are summarized above in English. In addition, use the SNOMED CT code 761996005 ‘Estimation technique (qualifier value)’ if the procedure standard has not been followed, and 272391002’ Measurement technique (qualifier value)’ otherwise.

Observation:extension.associatedCondition holds a reference to related municipality conditions. This is relevant when presenting observation results in municipality systems. In this profile, Observation.extension:associatedCondition is fixed to the SNOMED CT code 106063007 ‘Cardiovascular finding’.

Observation.note.text may be used to hold remarks about the observation.
