The Medication Identification List template defines the structure to identify the specific drug and drug strength that is the subject of the Medication List record as defined in the Medication Observation template.

CDA Extensions

This template includes the following CDA Extensions:

•   Drug Description: The Drug Description (LabeledDrug/e2e:desc)has been added to the schema to support a free form textual description of the drug. This is usually only populated for custom compounds, providing instructions on the composition and creation of the compound.

•   Drug Form: The Drug Form (LabeledDrug/e2e:formCode) has been added to the schema communicate the administration form of the drug (e.g. tablet, capsule, powder, etc.).

•   Drug Ingredient: Frequently the drug strength is assumed to be included in or implied by the drug code itself. For example, there is a specific DIN code for TYLENOL 325 mg tablet (00723894). However, the specification supports the communication of the drug strength attribute as a separate element to accommodate historical or patient reported data that may not be coded or may not have the strength pre-coordinated in the drug code or implied through the drug name. 

  
  

  0. Generic Name

     The Generic Name is used to communicate the generic ingredients that are included in the drug. This is included as the <translation> component of the Drug Code element which may repeat.

     In some cases there will be multiple generic named ingredients within the drug; for example, Tylenol 3 has acetaminophen 300mg and codeine 30mg and caffeine as generic ingredients. This element is a string format and there are no requirements for the display of the ingredient name, strength and units of measure; however, it is strongly recommended that the element repeat with each ingredient included in its own repetition. Having this recorded as a single text string causes difficulties for calculating defined daily dose when a medication formulation consists of a combination of different drugs.

     This field may be absent if a DIN code is provided as the receiving system may use the DIN code to identify the component generic ingredients.

     Drug Description

     The Drug Description is a free form textual description of the drug. This usually is only populated for custom compounds, providing instructions on the composition and creation of the compound.

     This field may also be used to provide more detailed and supplemental information regarding the Drug; however, dispensing and administration instructions should not be included here as there are specific instruction fields for that information.
