Rationale

Atrial fibrillation is a major risk factor for stroke, and when strokes occur in association with atrial fibrillation levels of mortality, morbidity and disability increase. Management of atrial fibrillation can prevent or reduce the number that lead to strokes. This indicator alongside NICE's indicator on atrial fibrillation: admission rates (stroke, on anticoagulation) aims to measure the rates of stroke in people with atrial fibrillation to see the impact of the management of atrial fibrillation. It will also identify people who are not being prescribed treatment that is ineffective for stroke prevention.

Specification

Numerator: Of the denominator, the number of patients not on anticoagulation before admission.

Denominator: All patients admitted to hospital with a primary diagnosis of stroke, who had a pre-existing diagnosis of atrial fibrillation.

Calculation: Numerator divided by the denominator, multiplied by 100.

Exclusions: None.

Data source: Sentinel Stroke National Audit Programme (SSNAP).

Minimum population: The indicator would be appropriate to assess the performance of networks or systems of providers.
