It seems to me to be a basic element of patient care, @QuintanaRoo. As I mentioned, I had a BP cuff on all night following gallbladder surgery 30 years ago, and my dad had one all that time ago too, after a stroke. I'm guessing my experience in the US was the result of a lot of number crunching because my health insurance provider wouldn't have paid for the monitoring if it hadn't been shown to be cost effective.
Whether a stroke is caused by high bp or not, hypertension is often present in stroke patients, and frequent bp readings can prevent errors in treatment. The new frontier of bp monitoring by means of cuffless monitors is advancing, in recognition of the quality of information frequent bp readings can give doctors managing stroke patients both in the hospital and after discharge. Even on a purely practical level, when wards are so short staffed, it surely makes sense to have machines take over some of the things that machines are really good at? You even avoid white coat syndrome when a machine inflates the cuff and takes the readings.
