Greetings,
I have reviewed the US Core specification but didn’t find the composition resource there. There are DocumentReference and DiagnosticReport described, as well as two corresponding search options. If I have a FHIR Document, it is a Composition. Is it supported by US Core? Can I search all three types of documents using one standard operation or should I call three separate searches and aggregate after receiving the response?
Thank you!
Kind regards,
Iryna
