How do you reduce falls????

Hello fellow ED RNs.

The ED I presently work at has just undergone a huge expansion of square footage. We are now seeing a rise in falls. The people falling are your usual folks, ETOH and demented folks come to the top of the list. We already have all the signage we need. Bed alarms in place. It seems the major problem is that, with the expanse of the ED, comes the decreased awareness of the alarms and the plant design itself makes it impossible to visualize these people every second. Any of you guys have any ideas. Thanks in advance.
