Description
To avoid confusion from the reader, explain that the average blood pressure (or other types of blood pressure measurements) is treated as a further refinement of the blood pressure profile and, therefore use the LOINC 85354-9 is used for all blood pressure measurements and additional LOINC codings to represent the types of blood pressure measurement such as average value. this is an inherited constraint from the FHIR Core Blood Pressure Profile https://hl7.org/fhir/R4/observation.html
implementations use this Resource when expressing the profile-specific concepts as structured data, they SHALL conform to the following profiles:
(edit final version)
Discussed this issue in January 2024 Virtual WGM Tuesday Q3 Call.
in relation to
- FHIR-43538 Confusing use of Observation.code values (hbuitendijk)
Which include Hans Buitendijk and Grahame Grieve. Summarizing:
- Not clear in the Profile documentation if the "magic codes" include component codes
- Currently, the FHIR validator enforces that rule clients get average BP measurements when they use the BP "magic code". There was disagreement on whether they should.
- Some systems may actually calculate average blood pressure on the fly when blood pressure are fetched. ( unclear on context )
