Medication Concepts

Medication Treatment (MT)

A set of 1..n medication treatment lines and associated information, somehow related together (e.g. one same purpose, or one same entry by a professional)

• 0..* Advice
  • Advice content
  • Advice issuer, date, etc.
  • Topic (link to treatment OR Link to treatment line OR overview)
• 0..* Comment
  • Comment content
  • Comment issuer, date, etc.
  • Topic (link to treatment OR Link to treatment line OR overview)

Medication Treatment Line (MTL)

• 1..1 Medication: an identification or sufficient description of the product (code / composition / …)
  • Dose form
• 1..1 Status
• 0..1 Route of administration (not 0..* - if there are changes, will be an update)
• 0..1 Dosage (strength, amount…)
  • may be a complex model e.g. one dosage for odd days and one for even days.
• 0..1 Frequency (dose units, timing, etc)
• 0..1 Effective time (duration, start+duration, start+end…)
• 0..* reason / indication
• 0..* Instructions
  • Preparation
  • Usage
  • (may be a link to an external request)
• Metadata (reporter, reporting date, etc.)
• 0..* Information sources: other data objects that this line is derived from (Order, Dispense, Line)
• 0..* category category of a medication line
• 0..* treatmentGroup (an explicit attribute that serves to associate 2 or more lines, in addition to the grouping that may be obtained from the other existing data elements)

Medication Treatment Plan (MTP)

Medication Treatment line that hasn’t been executed yet. A medication treatment line MAY have status “planned” (or no “actionable” status) but it’s still a line.

Subtype of Order, that hasn’t been executed yet and is not yet actionable.

For this reason, we will no longer use “Medication Treatment Plan” expression and concept in our specifications.
