Topic: MedicationStatement - future end date

Dusica Bojicic (Jun 03 2019 at 02:42):

We have a requirement to represent a medicine that a patient is currently taking, together with the expected date they will stop taking the medicine, e.g. it was asserted on the 11/12/2018 that a patient is currently taking Amoxicillin and is anticipated to stop taking it 20/01/2019.

We want to represent this using STU3 MedicationStatement resource where effectivePeriod.end would be used to represent the expected end date:

...
<status value="active"/>
    <medicationReference>
        <reference value="Medication/9fd129a4-8596-11e9-bc42-526af7764f64"/>
    </medicationReference>
    <effectivePeriod>
           <end value="2019-01-20" />
    </effectivePeriod>
    <dateAsserted value="2018-12-11"/>
    <subject>
        <reference value="Patient/55a2e4fc-8321-11e9-bc42-526af7764f64"/>
    </subject>
    <taken value="y"/>
...

Is this expected usage for MedicationStatement.effectivePeriod: to represent a date the patient is expected to stop taking medicine they are currently taking (e.g. when status=active, taken=yes, and effectivePeriod.end > assertedDate)?

Looking at the definition for effective[x] this seems like a reasonable option but both STU3 and R4 include this comment: “If the medication is still being taken at the time the statement is recorded, the "end" date will be omitted.”

We suggest this comment is actually misleading and should be removed from the current build.

Yes, you are probably correct that the comment is misleading. If you can create a gForge tracker item, we will address this right away.

Thanks @Jean Duteau, will do.
