    Cincinnati Prehospital Stroke Severity Scale (CP-SSS)

    Predicts large vessel occlusion (LVO) and severe stroke in patients with stroke symptoms.

    INSTRUCTIONS

    Use in a hospital setting in patients with signs and symptoms of acute ischemic stroke.

    When to Use
    Pearls/Pitfalls
    Why Use

    Patients in a hospital setting with signs and symptoms of acute ischemic stroke.

    • May be used to determine both severity of stroke, as quantified by NIHSS ≥15, and presence of LVO.
    • Accuracy at detecting LVO or severe stroke has not been evaluated when administered by EMS providers.
    • Acute stroke caused by LVO may be amenable to additional treatment beyond intravenous tissue plasminogen activator (tPA), including mechanical thrombectomy.
    • Benefit from mechanical thrombectomy in acute stroke from LVO is time-dependent, so early recognition may help timely mobilization of neurosurgical or endovascular care teams.
    • Based on three items from the NIH Stroke Scale (NIHSS), which is familiar to and easily administered by many emergency physicians and neurologists, as opposed to the LAMS, which is made up of three clinical items, one of which (grip strength) is not included in the NIHSS, and the RACE Scale, which includes more (six) clinical items.
