Re: NIHSS stroke scale
Thanks Beentheredonethat-you are very welcome.
I am not even sure if ROSIER (Recognition Of Stroke in ER) has been added to our protocol yet.It is an excellent tool which was developed for use by Doctors in ER, but is now being validated for use by paramedics. It is a step up from FAST, and aims to predict the likelyhood of stroke being the cause of the neurological deficit.
So presence of certain things are scored positively,whilst others are scored negatively.
As for NIHSS it was first developed purely for thrombolysis patients, and they are the only patients we use it for. Initially I used it for thrombolysis clinical trials 10 years ago and it does require certification every 2 years.
There is actually a move away from using the NIHSS in thrombolysis, purely because it is not an easy scale to use and requires some practice.
A patient can have an NIHHSS of 0 and still have had a stroke, so it is not a substitute for a full neuro exam to assess the type of stroke a patient has had ie the Bamford classification of stroke ie LACI,PACI,POCI or TACI.
It is the BAMFORD classification (plus CT evidence etc) which people use to quote mortality/recovery rates , either with or without thrombolysis treatment.
With experience you can tell very quickly using FAST and a few other quick tests what type of stroke they have had.
