Standards status: Trial-use Maturity Level: 4 Computable Name: QICoreMedicationStatement

Profile of MedicationStatement for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors.

"Must Have", "QI Elements" and "primary code path" are defined in the QI-Core Must Support section.
QI Elements:
  • subject: (QI) Who is/was taking the medication
  • status: (QI) active | completed | entered-in-error | intended | stopped | on-hold | unknown | not-taken
  • dateAsserted: (QI) When the statement was asserted?
  • derivedFrom: (QI) Additional supporting information
  • medication[x]: (QI) What medication was taken
  • effective[x]: (QI) The date/time or interval when the medication is/was/will be taken
  • informationSource: (QI) Person or organization that provided the information about the taking of this medication
Primary code path: medication
(PCPath) This element is the primary code path for this resource CQL Retrieve
