Cincinnati_Prehospital_Stroke_Severity_Scale_CP_SSS v.1
Helps to predict large vessel occlusion (LVO) and severe stroke in patients with stroke symptoms.
Used to predict large vessel occlusion (LVO) and severe stroke in patients with stroke symptoms.
Use in a hospital setting in patients with signs and symptoms of acute ischemic stroke. May be used to determine both severity of stroke, as quantified by NIHSS ≥15 (nih stroke scale score), and presence of LVO. The scale is based on four criteria, the final score calculated by the addition of selected points: - Conjugate gaze deviation: 2 points - Incorrectly answers ≥1 of two “level of consciousness” questions on NIHSS (age or current month) AND does not follow ≥1 of the two commands (close eyes, open/close hand)*: 1 point - Cannot hold arm (either or both) up for 10 seconds before arm(s) falls to bed**: 1 point *i.e., ≥1 on the NIHSS item for Level of Consciousness 1b and 1c. **i.e., ≥2 on the NIHSS item for Motor Arm. Interpretation CP-SSS LVO and NIHSS: -Score: 0–1 LVO and NIHSS ≥15 less likely -Score: 2–4 LVO and NIHSS ≥15 likely. Consider initiating full workup and treatment for LVO as appropriate, including CT angiogram.
Accuracy at detecting LVO or severe stroke has not been evaluated when administered by EMS providers. Should not be used as a substitute for clinical judgment, and is intended for use as an adjunct to medical decision-making.
