Abstract
IntroductionFew emergency department (ED)-specific fall-risk screening tools exist. The goals of this study were to externally validate Tiedemann et al’s two-item, ED-specific fall screening tool and test handgrip strength to determine their ability to predict future falls. We hypothesized that both the two-item fall screening and handgrip strength would identify older adults at increased risk of falling.MethodsA convenience sample of patients ages 65 and older presenting to a single-center academic ED were enrolled. Patients were asked screening questions and had their handgrip strength measured during their ED visit. Patients were given one point if they answered “yes” to “Are you taking six or more medications?” and two points for answering “yes” to “Have you had two or more falls in the past year?” to give a cumulative score from 0 to 3. Participants had monthly follow- ups, via postcard questionnaires, for six months after their ED visit. We performed sensitivity and specificity analyses, and used likelihood ratios and frequencies to assess the relationship between risk factors and falls, fall-related injury, and death.ResultsIn this study, 247 participants were enrolled with 143 participants completing follow-up (58%). During the six-month follow-up period, 34% of participants had at least one fall and 30 patients died (12.1%). Fall rates for individual Tiedemann scores were 14.3%, 33.3%, 60.0% and 72.2% for scores of 0,1, 2 and 3, respectively. Low handgrip strength was associated with a higher proportion of falls (46.3%), but had poor sensitivity (52.1%).ConclusionHandgrip strength was not sensitive in screening older adults for future falls. The Tiedemann rule differentiated older adults who were at high risk for future falls from low risk individuals, and can be considered by EDs wanting to screen older adults for future fall risk.

Summary
Few emergency department (ED)-specific fall-risk screening tools exist. The goals of this study were to externally validate Tiedemann et al’s two-item, ED-specific fall screening tool and test handgrip strength to determine their ability to predict future falls. We hypothesized that both the two-item fall screening and handgrip strength would identify older adults at increased risk of falling. Of patients admitted to the hospital with a ground level fall, 44% are readmitted and 33% die within one year.[5,6,7] Those who present to the ED with fallrelated injuries and are discharged have higher rates of future falls, functional decline, and additional ED visit within three months than other older adults.[8,9]
