What score is used by NICE to assess stroke symptoms in an acute setting?

Framingham risk score
Rosier score
CHA2DS2-VASc score
AHA stroke scale

The correct answer is: Rosier score

The Rosier score is specifically designed for the rapid assessment of stroke symptoms in an acute setting. It is a validated scoring tool that helps clinicians evaluate patients who may be experiencing a transient ischemic attack (TIA) or stroke by assessing various clinical features. The score includes elements such as the patient's level of consciousness, gaze palsy, arm weakness, leg weakness, speech difficulties, and whether it was witnessed. A higher Rosier score indicates a greater likelihood of a stroke, thus guiding clinicians in making prompt treatment decisions. Its application aids in stratifying risk and determining the appropriateness of further diagnostic imaging or interventions, which is crucial in acute emergency settings where time-sensitive decisions are paramount. The other scoring systems mentioned serve different purposes. The Framingham risk score is primarily used for estimating the 10-year cardiovascular risk of heart disease, while the CHA2DS2-VASc score is utilized for assessing stroke risk in patients with atrial fibrillation. The AHA stroke scale, also known as the NIH Stroke Scale, evaluates the effects of a stroke once it has occurred, rather than assessing for the acute onset of symptoms. Thus, the Rosier score stands out as the most relevant tool for the immediate evaluation of stroke symptoms.
