Ten Minute Safety Walks

I have a friend that works in a nursing home and ask me if I have ever read anything about ten minute safety walks. She said, one of their supervisors went to a meeting and come back with this great idea for them to do 10 minute safety checks on q patient on the unit. No matter what they are doing ( they take turns) they must stop and do a walk. They check to make sure bed or chair alarms are still on and if a pt. is sitting in their room that they are still there. They can not stop and clean or dry a pt. at this time. It sounds like alot of waste time to me. The purpose I believe is to cut down on falls. I don't believe this has changed since they started. I just can't believe it is more important to do a walk than to finish feeding a patient ! Has anybody had to do this ? If so, how long and did it impact the # of falls you had ?
