NCT05602740

Brief Summary

Prehospital providers encounter patients with suspected stroke frequently. Prehospital providers need tools to help triage large vessel stroke patients to comprehensive stroke centers. This device will identify large vessel stroke to ultimately improve triage decisions and optimize outcomes.

Outcome Measures

Primary Outcomes (1)

  • The primary effectiveness objective is to estimate the sensitivity and specificity of LVO diagnosis with Harmony®.

    The subject's final discharge diagnosis based on the CTA scan and the neurologist's assessment will serve as the "ground truth" diagnosis. The sensitivity and specificity will be estimated as the point estimate (Harmony® identified correctly divided by the ground truth number); the confidence intervals will be estimated by the Clopper-Pearson method (exact intervals for proportions).

    Through study completion, an average of 6 months
