MedicationStatement
The following topic describes information for the MedicationStatement resource.
To interact with the REST endpoints in the MedicationStatement resource, see MedicationStatement.
Overview
The MedicationStatement resource provides a snapshot in time of known medications taken by the patient now or in the past, which were reported by the patient, a significant other, or a provider. Future orders are not returned.
Historical, past, or home medications are commonly captured when documenting the patient's medical history. Prescriptions without documented compliance are considered intended because whether the patient is actively taking the medication or has filled the prescription is unknown. Medications are assumed to be taken unless documented otherwise.
The following fields are returned if valued:
-
Category Extension (for more information, see the Extensions section of this topic)
-
Details of medication taken:
-
Patient friendly display Extension (for more information, see the Extensions section of this topic)
Querying for Active Medications
To get all possible current medications, an application should query the
MedicationStatement resource with the status
query parameter set to
active,intended
. Because the MedicationStatement resource provides a
snapshot in time, the reponse includes only the information that was in the system as of the
last contact with the patient. Changes in medications that occurred after the patient last
visited their provider are not included.
To get the list of current medications that would likely be shown by default to a
practitioner, use the MedicationOrder resource and the
query above to ensure that draft
orders are included. You can use the
MedicationStatement.supportingInformation
reference to remove duplicates.
A duplicate is identified when the MedicationOrder.id
is equivalent to the
MedicationOrder/[id]
in the supportingInformation
reference.
