Description
Finding:

- In the ePrescription document, the hl7:supply indicates the number of packages and is reused by the portal to generate the eDispensation message.

An issue was discovered in the portal when a unit of measure was used to indicate the number of packages:

Following entry in the eP:

<supply classCode="SPLY" moodCode="RQO">                                 
    <independentInd value="false"/>                                   
    <quantity unit="g" value="100.0"/>                               
</supply>

generates following element in the eD:

<quantity unit="1" value="100.0"/>

So the 'g' is lost. But according to the specifications, the unit must always be set to '1':

The supply entry shall indicate the number of packages available for dispensation on the prescription.

The value attribute shall be present and indicate the number of packages. In prescriptions for overall amount (such as 400 tablets), the value attribute must equal 1, and the overall amount shall be placed in epsos:containerPackageMedicine/epsos:capacityQuantity element. See its description for more information.

The unit attribute shall be present and equal UCUM unit 1 .

This constraint has to be added to the eHDSI SubstanceAdministration template. Currently it is just a textual constraint.


Suggestion:

Set a fixed value of '1' for the unit attribute if it is provided.
