Cincinnati Prehospital Stroke Severity Scale (CP-SSS)

Identifies patients with large vessel occlusion (LVO) stroke in the prehospital setting to guide direct transfer to stroke centres capable of mechanical thrombectomy.

Score interpretation

LVO Likely — Thrombectomy Centre

→ CP-SSS ≥2: High likelihood of large vessel occlusion. Transport directly to comprehensive stroke centre capable of mechanical thrombectomy, bypassing closer hospitals if necessary. Stroke team pre-alert.

LVO Less Likely

→ CP-SSS 0–1: LVO less likely. Transport to nearest stroke centre capable of IV thrombolysis. IV tPA if within window and no contraindications. CT/CTA on arrival to rule out LVO.

Interpretation bands for the CP-SSS. Apply clinical judgement and local guidance.
