MedicationStatement read

get/MedicationStatement/{id}
Page View

This resource contains one or more statements about a medication that a patient has taken, is currently taking, or may take in the future. A patient, related person, or clinician may make the statement(s).

The difference between this and MedicationAdministration is that MedicationStatement contains informal statements rather than official administration details, such as dosage or date/time of administration. The information likely isn’t as specific, since the statement might come from a patient’s account or a list that a related person may maintain for the patient.

You can review or retrieve a list of medication statements for a patient.

read

Review a specific MedicationStatement resource with a list of medication statements given by or on behalf of a patient.

To use a read interaction, you must know the related resource ID, which you may not have in your real workflows. A read is likely only a follow-up option after receiving the specific resource in a recent FHIR® passthrough or data on demand exchange.

Typically, you should use the more flexible _search with query parameters, unless you're guaranteed to request data directly from a FHIR® server using the resource ID. Learn more about using FHIR® identifiers.
