Frailty Index most accurately predicts adverse events following a fall. Injury Severity Score determines trauma severity in relation to morbidity, hospitalization, and fatality, but is less accurate than the frailty index. Nurses perform fall risk assessments as a part of their routine care among elderly patients. Morse Fall Scale is a commonly-used method in rating fall risk factors such as history of falls, gait, mental status, ambulatory aids, intravenous access and others. The Beers Criteria is a list of drugs that have the potential to increase the risk of fall and injury among older adults.
