Quality statement 5 – Minimising risk of another stroke Indicator 5b: Discharge on statin, antihypertensive and antithrombotic medications (ischaemic stroke) Definitional attributes Name: Proportion of patients with a final diagnosis of ischaemic stroke who are discharged on statin, antihypertensive and antithrombotic medications, where not contraindicated. Rationale: Ischaemic stroke patients should be discharged on statin, antihypertensive and antithrombotic medications to ensure optimal outcomes. Lowering lipid levels (using a statin) is an effective primary and secondary prevention treatment for vascular events, including stroke.1 The use of antiplatelet drugs has been shown to provide a 22% reduction in vascular events (myocardial infarction, stroke or vascular death) in patients with a previous stroke or transient ischaemic attack (TIA).2 Most antihypertensive drugs have been shown to reduce blood pressure, the recurrence of stroke and cardiovascular events.3 Collection and usage attributes Computation: (Numerator ÷ denominator) x 100 Numerators: Patients with a final diagnosis of ischaemic stroke discharged from hospital on statin, antihypertensive and antithrombotic medications, where not contraindicated.
