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, not on anticoagulation) aims to measure the percentage of people with atrial fibrillation who are receiving effective treatment for prevention of stroke.

Specification
Numerator: The number of patients in the denominator on anticoagulation before admission.
Denominator: The number of 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.
