BACKGROUND Falls are common in community-dwelling elderly persons and are a frequent source of morbidity . Simple indices to prospect ively stratify people into categories at different fall-risk would be useful to health care practitioners . Our goal was to develop a fall-risk index that discriminated between people at high and low risk of falling . METHODS We evaluated the risk of falling over a one-year period in 557 elderly persons ( mean age 81.6 ) living in a retirement community . On the baseline interview , we asked subjects if they had fallen in the previous year and evaluated  risk factors  in six additional conceptual categories . On the follow-up interview one year later , we again asked subjects if they had fallen in the prior year . We evaluated risk factors in the different conceptual categories and used logistic regression to determine the independent predictors of falling over a one-year period . We used these independent predictors to create a fall-risk index . We compared the ability of a prior falls history with other risk factors and with the combination of a falls history and other risk factors to discriminate fallers from nonfallers . RESULTS A fall in the previous year ( OR = 2.42 , 95 % CI = 1.49 - 3.93 ) , a symptom of either balance difficulty or dizziness ( OR = 1.83 , 95 % CI = 1.16 - 2.89 ) , or an abnormal mobility exam ( OR = 2.64 , 95 % CI = 1.64 - 4.26 ) were independent predictors of falling over the subsequent year . These three risk factors together ( c statistic = .71 ) discriminated fallers from nonfallers better than previous history of falls alone ( c statistic = .61 ) or the symptomatic and exam risk factors alone ( c statistic = .68 ) . When combined into a risk index , the three independent risk factors stratify people into groups whose risk for falling over the subsequent year ranges from 10 % to 51 % . CONCLUSION A history of falling over the prior year , a risk factor that can be obtained from a clinical history ( balance difficulty or dizziness ) , and a risk factor that can be obtained from a physical exam ( mobility difficulty ) stratify people into groups at low and high risk of falling over the subsequent year . This risk index may provide a simple method of assessing fall risk in community-dwelling elderly persons . However , it requires validation in other subjects before it can be recommended for widespread use
