Topic: Determining if a medication dose is weight-based
Floyd Eisenberg (May 06 2020 at 15:43):
Is there a way to identify that a medication dose was determined by weight-based dosing or body surface area calculation? While an EHR may provide the mechanism to do either as required, how is the resulting dose tagged to indicate the calculation method? Is this information available as metadata for an interoperable message in a MedicationRequest, MedicationStatement, or as MedicationAdministration? @Robert McClure also interested.

In the Dosage type, there is an attribute Dosage.doseAndRate.type that includes an exemplar value set of "calculated" and "ordered", but no specific place to include the actual method. In doseAndRate, you can specify a dose that is based on BSA - see example http://build.fhir.org/medicationrequest0309.xml.html . Dosage included in MedRequest, MedDispense and MedStatement, but not in MedAdministration as it doesn't make sense to include some of the options that Dosage allows. MedAdmin says "I gave this amount". If you think you need another attribute, I suggest you add a JIRA issue.

There's a standard extension that allows a CQL or FHIRPath expression to be included for any element - so that would be one option.
