Topic: Dosage instruction with start date and duration

Gou Masuda (Jul 16 2020 at 21:51):

Hello, everyone.

When I represent a medication request which has dosage instruction with start date and duration, such as "BID, start on 7/1/2020, for 10 days", how can I do this?

I think I can use Dosage.timing.boundsPeriod and Dosage.timing.boundsDuration, but I can't have both properties at the same instance.

Do I need two Dosage instances? One has timing.boundPeriod and another has boundsDuration. If so, instruction "BID" is represented in the both Dosage instances?

Thanks.

You would use boundsPeriod - [7/1/2020, 7/10/2020]

Thank you for your reply.
How would you represent if the number of days from the start date to the end date and the dose period differ such as a prescription of administering on every other day?

For example, "ordered at 7/1/2020, start on 7/6/2020, for 7 days every other day (that is, from 7/6/2020 to 7/18/2020)".

"timing": {
  "boundsPeriod: {
    "start: "2020-07-06",
    "end": "2020-07-18"
  },
  "frequency": 1,
  "period": 2,
  "periodUnit": "d"
}

Is there any way to explicitly express a 7-day dosing period on my instance?
Thanks.

It seems that by "dose period", you are saying that even the administration period is 15 days, the dispensed days supply is only 7 days. That would go in MedicationRequest.dispenseRequest.expectedSupplyDuration = 7 days
