Alzheimer's patient and hospital bed or bed rails in assisted living, any recommendations?

My dads AL then SNF would not allow rails, per law I guess. but hospice eventually put in a mattress that sort of looked like a half pipe for snow boarders in the Olympics. Not fool proof, he could climb out if he wanted to, but more difficult, and he would not roll out.

Its the law not the AL requirement. Believe me, the aides jobs would be so much easier if they were allowed to use them. Mom had a small pull up rail theybwouldn't allow her to use. Wanted her to use a hallo but she had a bad shoulder. Like posted. There are concaved mattresses to help keep them from falling out. Mats for the floors. But nothing to keep them in bed. Actually, if he wanted to get out of bed bad enough, he could climb over the rails.

Unfortunately, the government has done extensive research and they have decided that it is better to allow a resident/patient to fall out of bed then to suffer "Strangling, suffocating, bodily injury or death when patients or part of their body are caught between rails or between the bed rails and mattress."  {There have been many lawsuits because side rails have resulted in injury or death.}

Hospitals, assisted living facilities, nursing homes, and home health agencies have to PROVE that side rails are "BENEFICIAL" for the patient/resident and prevention of falls is NOT a good reason to put side rails on a bed.

A low bed or also called and “Alzheimer’s” bed has a lower bed deck for patients who are fall risks and falling out of bed could be dangerous. A low bed makes the fall a short trip. Adding a padded fall mat can also greatly reduce the amount of injury suffered by a patient. Low beds are exactly like full electric beds with the exception of the 9 ½“bed deck height, when a 6” mattress is added the lowest height from the floor is only 15 ½“versus the 15”-20” a standard bed, and will raise itself 5” to help the patient get out of bed with limited strain to their legs, hips and knees. “Alzheimer’s” beds are a great benefit for caregivers too, caregivers who have to lift a patient out of bed by either assisting a patient or using a patient lift have the added benefit of raising and lowering the bed without having to turn a crank to get the correct height.

I have fought this battle for over 20 years and the government will always win.  Facilities that put bed rails on their beds are FINED and even CLOSED for violating federal regulations.  

I am sorry that your FIL is have this problem.  Maybe a LOW BED would be a better solution depending on the reason he is getting out of bed.  If FIL has to go to bathroom several times during the night, maybe his medication needs to be changed or he needs to drink less water in the evening.  Investigate the reason your FIL is getting out of bed so often during the night and see if you can find a solution by correcting or treating the reason FIL gets out of bed.

My mother admitted she wanted the bed with rails to keep him in bed. I told her that his aids needed to do their jobs and make sure he does not fall. I am going to get him one of the beds that lowers.
Thanks!
