Computation description:

Both the numerator and the denominator include patients with a final diagnosis of ischaemic stroke.

The numerator requires evidence of prescription and administration of antithrombotics prior to separation. Antithrombotic medications include: oral anticoagulants, such as warfarin, apixaban, rivaroxaban or dabigatran; and antiplatelet agents, such as aspirin, clopidogrel and dipyridamole.

  • decline treatment
  • where there are limitations of therapy (i.e. advance care directive is enacted and/or the patient is on a palliative care pathway).
