Patients with a score of 4 or more – refer for specialist assessment within 24 hours of the onset of symptoms. This may require admission to hospital.

Patients with a score of 0-3 – refer for specialist assessment as soon as possible, but definitely within one week of onset of symptoms.

Patients who present more than a week after their last symptoms have resolved – treat as per patients who score 0-3.
