Vital signs observations have predefined profiles defined by HL7 International. The goal of the HL7 vital signs profiles are:
The FHIR Vital Signs profile sets minimum expectations for the Observation resource to record, search and fetch the vital signs associated with a patient that include the primary vital signs plus additional measurements such as height, weight and BMI.
These profiles defines a LOINC "magic value" for use in Observation.code to tell what is being measured. The use of LOINC is challenging in Norway as the CodeSystem is not in common use by clinicians and IT-systems generally don't support LOINC codes. In Norway we would suggest to always exchange vital signs observations with an additional SNOMED CT code for better semantic interoperability. The following principles have been defined for the use of LOINC magic values and additional SNOMED CT coding in the Observation.code element:
Tok bort barn av 1:1 koding etter møte med HL7 Norge TSK
LOINC slicen gir liten klinisk verdi, SNOMED gir liten klinisk verdi
Vi vinner det at vi kan legge over til SNOMED gradvis
Vi trenger 1:1 for å være presis i forhold til hva vi faktisk uttrykker i instansen
Påvirke vital-sign til å bli bedre internasjonalt
Er 1:1 mappingen obligatorisk fra internasjonalt? (jeg tror det er best practice)
Ingen konklusjon
Kodeeksempel med tre koder i henhold til prinsipper
<code>
<coding>
<system value="http://loinc.org"/>
<code value="8867-4"/> <!-- Dette er obligatorisk LOINC-->
<display value="Heart rate"/>
</coding>
<coding>
<system value="http://snomed.info/sct"/>
<code value="364075005"/> <!-- 1:1 mapping til info -->
<display value="Heart Rate"/>
</coding>
<coding>
<system value="http://snomed.info/sct"/>
<code value="78564009"/> <!-- Dette er puls, slicen bør begrenses i forhold til hvilke SNOMED CT begreper som skal benyttes-->
<display value="Heart rate measured at systemic artery (observable entity)"/>
</coding>
<text value="Heartrate"/>

Bør applisere prinsippet på vitale-parametere siden LOINC er obligatorisk for disse målingene. Det er kanskje ikke relevant som et generelt prinsipp med mindre det endres noe.
Knytter denne saken til områdeprofilene og dokumentere prinsippet i forbindelse med no-domain.
