Forty one thought they were confused at some time
during their stay in the ICU. Five more, as mentioned earlier, had no recollection of their stay. The nurses
recorded that three quarters of the patients were correctly
orientated most of the time, but that half of them were
drowsy for some of it. They observed frank confusion at
some time in only five patients, two of whom belonged to
the small group with no recollection of their time in the
ICU.
