The problem with using icp to predict things is that it's an invasive procedure. So, the patients who have them will have already had a bleed/ traumatic injury etc and we already use it to monitor for the need for more invasive procedures such as a craniotomy. And, if they have a cranie and still have an evd in place it's not going to be completely accurate.

So, if you're already monitoring the patient in the ICU its helpful, but this isn't going to help the average patient pre hospitalization.
