Some kind of reading material
Pen and small tablet
Wipes of some kind, you may be in bed longer than you expect
My sister wasn't allowed underwear, but she was in the ICU
Mouthwash if you don't feel up to brushing
Inflatable travel pillow (for the family member)
Cell phone cord? the roommate might want some rest
An SAK? they might confiscate it as a weapon
Otherwise your list looks extremely good, just include several rolls of quarter for the vending machines-it's not possible to have too much change, in my experience.
