I suppose the number one thing is preventing injury. I was just at the allnurses.com forum yesterday and there was a story of a nurse who hurt her back while assisting another nurse, will probably not work as a nurse again, and is scrambling for other ways to support her family. I have worked in about every setting, and formal measures never worked for us. Each morning, I would either ask the tech whose assignment was in front of me, or in back of be (whomever I was more familiar with) and asked them if they needed help pulling people up for the first meal of the day. We would do their team, then mine. This built immediate rapport and almost always led to team lifting, team bathing on the big ones, and even team tray collection. If you could find another person cool enough to stick to the plan, it was great.
Just my 2 cents,
