Topic: Cholesterol fasting indication
John Moehrke (Oct 22 2018 at 15:59):
I am now using the lipid-report recommendation to record Cholesterol as a DiagnosticReport with 4 Observations. However I also have a true/false indication of if the patient was fasting or not. Where does this go? It doesn't seem to be a standalone Observation. It feels more like a component of the 4 Observations.

are you asking for R3 or R4?
John Moehrke (Oct 22 2018 at 19:05):
R3 for now.. eventually R4... Not sure how the R level affects the answer.
Grahame Grieve (Oct 22 2018 at 19:12):
in R3: Observation.related[type = 'qualified-by'].target
Grahame Grieve (Oct 22 2018 at 19:12):
in R4: that was taken out and it's an extension
John Moehrke (Oct 22 2018 at 19:16):
okay, let me restate to see if I understand. The DiagnosticReport points at four Observations, those four Observations .related.target would point at the fifth Observation that holds the fasting indication true/false. -- which means, yes five Observations.
Grahame Grieve (Oct 22 2018 at 19:22):
yes I think so
Eric Haas (Oct 22 2018 at 22:30):
in R4 we made it an attribute of the specimen: http://build.fhir.org/specimen.html
Eric Haas (Oct 22 2018 at 22:36):
It can - like most other things - be represented as an Observation too. I think it would be best represented using the http://build.fhir.org/extension-observation-precondition.html or simply grouped as part of a panel of observations.
Grahame Grieve (Oct 22 2018 at 22:43):
ah yes that would be extension. I think that replaces qualified-by in R3
