TID 8131 Medications and Mixture Medications

This template encodes a description of medications (including but not limited to anesthetic agents) used during a procedure (e.g., pre-medication drugs for an imaging procedure on humans, or anesthesia for imaging of research small animals).

Note

This template combines selected concepts from the [AQI Schema] elements, their complex types, and their children:

Content Item Descriptions

Row 1

AQI Medication type and element correspond to (182833002, SCT, "Medication given") (situation). (See TID 3806 Cath Procedure).

Rows 2-3

AQI DoseStart and DoseEnd elements correspond to (122081, DCM, "Drug start") and (122082, DCM, "Drug end") respectively. (See CID 3409 Administration of Drugs/Contrast). If the medication is delivered as a bolus, the end time is omitted.

Row 4

AQI MedicationRoute corresponds to (410675002, SCT, "Route of administration"). The existing CID 11 “Route of Administration” contains a relevant subset of concepts for the enumerated values of AQI MedicationRouteCodeType.

Row 5

The AQI schema allows the Medication type not only to describe medications with a single component, but also to add MixtureMedications children, each of which is encoded following a similar pattern to the contents of Medication, though the start and end time and route of administration are shared. This had been modeled by allowing every medication to have one or more mixture children. For medications that are not a mixture, a single instance of this row defines the medication (even though the mixture container is still used).

Rows 6, 7

AQI MedicationName and MixtureMedicationName elements correspond to (122083, DCM, "Drug administered"). (See TID 3806 Cath Procedure). The medication (e.g., anesthesia agent) can be described with a code or text, e.g., (387368002, SCT, "Isoflurane") or "isoflurane".

Row 9

Both AQI MedDose (or MixtureMedDose) and DoseUnits (or MixtureDoseUnits) elements are combined in one content item. Units are required to be encoded as UCUM but are not otherwise constrained.

Row 10

Both AQI MedConcentration (or MixtureMedConcentration) and MedConcentrationUnit (or MixtureMedConcentrationUnit) elements are combined in one content item. Units are required to be encoded as UCUM but are not otherwise constrained.

Row 11

Registered drug establishment code for the product. Equivalent codes can be encoded in this item using the Equivalent Code Sequence (0008,0121). See Section 8.9 “Equivalent Code Sequence” in PS3.3 .
