"Missing nursing notes"

I was in Ward 2 of the Monklands in February at 6pm while a auxiliary was about to do my observations they realised my nursing notes where missing and hadn't been seen from 2pm (a student told me this) I was discharged the next day around 6pm. as of 1pm the notes where still missing when I asked.

Noone official told me there missing, I only knew as a staff member looked under my mattress as I lay in the bed, I wasn't told what information was missing (name, address, dob, telephone) never mind all my observations and health details and other data I may not even realise was in it. I don't know if the data protection officer was informed of this breach of data and still to this day I don't know if these notes where ever found, who has them, and members of the public entering the ward had access to them as they hand outside the 4 bedded room for anyone to look at and steal?
