Description:Help on this term

Proportion of patients with a final diagnosis of acute stroke who were transported by ambulance to a hospital able to provide thrombolysis.

Rationale:Help on this term

Access to thrombolysis remains low in Australia, though some Australian centres have achieved thrombolysis rates of 20% (NSF 2013). Access to timely thrombolysis is a validated predictor of ischaemic stroke patient outcome, shown to reduce length of acute stay and potentially reduce in-hospital mortality (Hamidon & Dewey 2007).

Collection and usage attributes

Computation description:Help on this term

The reference population for this indicator could be the ambulance service or local hospital network (LHN). The choice of reference population depends on the service that is generating the indicators for local review (i.e. ambulance or health service), and the structure of ambulance services (i.e. whether they map to LHNs).

Both the numerator and the denominator include patients with a final diagnosis of acute stroke. The final diagnosis is made at the hospital where the patient is admitted for the acute phase of management of their stroke.

Both the numerator and denominator exclude:

  • Patients who are elective admissions.
  • Patients who have a stroke in the hospital.
  • Patients for whom it is not possible to administer thrombolysis within 4.5 hours of symptom onset.

Presented as a percentage.
