Yes we document every fall, even if it wasn't witnessed, but we don't chart it as Resident found on floor, we chart, resident observed to by lying, sitting, etc, then do the head to toe.
We started using one of the assessments that we do on admission and quarterly as a guide to who needed to be on a fall prevention program. It is effective because you can add or delete residents from the program, and keep up on it more closely, residents may be high risk one time, but then need re-evaluation too. The assessment is the Fall Risk assessment and can be ordered through briggs, if the score is higher than 10, I think, then the person is placed on the fall program. We used the falling leaf program, placing a leaf on the pts door, w/c or walker, above their bed, and inside the pt's chart.
