What is the best of the LVO prediction instruments in a setting where confirmed ischemic stroke patients are assessed by a neurologist or emergency physician in the ED?
The authors of a recent systematic review suggested that the NIHSS score is the best of the LVO prediction instruments in a setting where confirmed ischemic stroke patients are assessed by a neurologist or emergency physician in the ED. According to their meta-analysis, a threshold of 10 would provide the optimal balance between sensitivity (73%) and specificity (74%). To maximize sensitivity (at the cost of lower specificity), a threshold of 6 would have 87% sensitivity and 52% specificity.
