Summary

Accurate stroke identification by emergency dispatch is critical, but stroke mimics can drive overtriage. This Norwegian study found that its central dispatch system stroke criteria had low positive predictive value, indicating substantial early overtriage, while universal criteria better distinguished confirmed strokes. The findings underscore the operational burden of stroke mimics and the need to refine dispatch strategies.
