Medication Request
The below sample describes a Medication request
Note: The FHIR standard allows many different formats for the timing element. However, in this implementation the timing format assumed is "frequency" times in a particular "period" between "boundsPeriod". For example, 3 times a day between 2020-08-03 and 2020-08-06. If other formats are also required please let us know.
