The tool is called the neurovascular comorbidity index (NCI), and it's designed specifically for patients with stroke.
The NCI looks at 20 different health conditions that can affect stroke patients, like high blood pressure or diabetes. It gives each condition a score based on how much it affects the patient's outcome.
Doctors can use the NCI to predict how likely a patient is to die in the hospital or have a poor outcome after treatment.
The NCI was tested on patients who received reperfusion treatment, which is a type of treatment that helps restore blood flow to the brain.
