Medication
Introduction #
The Medication model represents a record of a medication that is being consumed by a patient, either now, in the past, or in the future. Medication records can represent both prescriptions and medication statements for a patient.
Basic usage #
To get a medication by identifier, use the get method on the Medication model manager:
from canvas_sdk.v1.data.medication import Medication
medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
If you have a patient object, the medications for a patient can be accessed with the medications attribute on a Patient object:
from canvas_sdk.v1.data.patient import Patient
patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
medications = patient.medications.all()
If you have a patient ID, you can get the medications for the patient with the for_patient method on the Medication model manager:
from canvas_sdk.v1.data.medication import Medication
patient_id = "1eed3ea2a8d546a1b681a2a45de1d790"
medication = Medication.objects.for_patient(patient_id)
Codings #
The codings for a medication can be accessed with the codings attribute on an Medication object:
from canvas_sdk.v1.data.medication import Medication
from logger import log
medication = Medication.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")
for coding in medication.codings.all():
log.info(f"system: {coding.system}")
log.info(f"code: {coding.code}")
log.info(f"display: {coding.display}")
Filtering #
Medications can be filtered by any attribute that exists on the model.
Filtering for medications is done with the filter method on the Medication model manager.
By attribute #
Specify an attribute with filter to filter by that attribute:
from canvas_sdk.v1.data.medication import Medication
medications = Medication.objects.filter(status="active")
By ValueSet #
Filtering by ValueSet works a little differently. The find method on the model manager is used to perform ValueSet filtering:
from canvas_sdk.v1.data.medication import Medication
from canvas_sdk.value_set.v022.medication import AdhdMedications
medications = Medication.objects.find(AdhdMedications)
