Computation description:Help on this term

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

Atrial fibrillation includes patients where Episode of care—principal diagnosis, code (ICD-10-AM 11th edn) ANN{.N[N]} or Episode of care—additional diagnosis, code (ICD-10-AM 11th edn) ANN{.N[N]} is one of the following:

  • I48.0 Paroxysmal atrial fibrillation
  • I48.1 Persistent atrial fibrillation
  • I48.2 Chronic atrial fibrillation
  • I48.3 Typical atrial flutter (Type I atrial flutter)
  • I48.4 Atypical atrial flutter (Type II atrial flutter)
  • I48.9 Atrial fibrillation and atrial flutter, unspecified.

The diagnosis of atrial fibrillation is in addition to the diagnosis of ischaemic stroke.

The numerator requires evidence of prescription of oral anticoagulation therapy at the point of the patient being separated from hospital. 

Oral anticoagulants include warfarin, apixaban, rivaroxaban or dabigatran.

Both the numerator and the denominator exclude patients for whom oral anticoagulants are contraindicated and the contraindication is clearly documented. 

Both the numerator and denominator exlude patients who:

  • decline treatment
  • die in hospital or are placed on a palliative care pathway

Presented as a percentage.
