Prehospital stroke detection scales generally exhibited high sensitivity but low specificity. While LAPSS performed poorest, MedPACS, sNIHSS-EMS and OPSS demonstrated the highest accuracy and missed the fewest reperfusion-treated stroke patients. Use of the most accurate scale could reduce unnecessary stroke code activations for patients with a stroke mimic by almost a third, but at the cost of missing 16% of strokes and 10% of patients who received reperfusion treatment.
