In the last few places I have worked (PCUs) we used the fall risk assessment. Patients and family members were told the reason for someone to accompany the pt to the BR or the need for a bsc. Signs are posted on the wall in the room explaining the different helps for high risk patients. All IV poles/lines are situated as well as possible toward the toilet so if a patient decides to get up on their own it is not a hindrance. We also only put up the top half of the rails so they can reach the controls, not the bottom. Once again, if they decide to get up, even if disoriented, the risk of injury is much less if they are not crawling out the end of the bed.
I personally have released many patients from wrist or vest restraints when I come in the morning. I find that either they have rested and are oriented, they can see in the daylight, they feel better, family is/are around, there are more ancillary staff such as housekeeping, kitchen aids, PT/OT, resp, etc, but most of my patients do not need to be restrained. We also ask the patient frequently if they need to go to the BR. This lessens accidents in the bed and the slips in urine or other "stuff".
There is a TON of lit out there about fall prevention. Good luck.
