Description
It will be common for the patient to have discrete blood pressure measurements, which the specification already supports returning as a blood pressure at a datetime. It sounds like the requirements for Average Blood Pressure are that the average should be computed from these discrete measurements based on the search query, or at least this would be one way to return one or more averages and satisfy the requirements.
When a FHIR search requests all vital signs for a patient but doesn't specify a single date range, what should be returned as the Average Blood Pressure for that patient? Should multiple averages be computed and returned? What if the FHIR search request includes only a single datetime? What if the FHIR search request includes two or more date ranges? What if the multiple date ranges do overlap, and what if they don't?
I would like the specification to clarify whether the system is expected to compute the average blood pressure from available blood pressure observations, and if so, which observations and which method of averaging.
I think that the intention might be that the system only returns an Average Blood Pressure if the average is what was documented by the user or the average is what is stored in the system prior to the query.
In the case that a user-entered average is documented in the system and doesn't need to be computed for the query, should it be returned if the period of the average only partially overlaps with the date range specified by the search query?
I would like the specification to clarify how the date search parameter interacts with the period of the average blood pressure.
