Description:Objectives
To compare the ability of frailty status to predict fall risk with that of community fall risk screening tools.
Design
Setting
National Health and Aging Trend Study (NHATS) 2011
Participants
Individuals aged 65 and older (N=7,392).
Measurements
Fall risk was defined according to the Stopping Elderly Accidents, Deaths and Injuries (STEADI) initiative. Frailty was defined as exhaustion, weight loss, low activity, slow gait speed, and weak grip strength. Robust was defined as meeting 0 criteria, prefrailty as 1 or 2 criteria, and frailty as 3 or more criteria. Falls were self-reported and ascertained using NHATS subsequent rounds (2012–2015). We compared the ability of frailty to predict future falls with that of STEADI score, adjusting for age, race, sex, education, comorbidities, hearing and vision impairment, and disability.
Results
Of the 7,392 participants (58.5% female), there 3,545 (48.0%) were classified as being at low risk of falling, 2,966 (40.1%) as being at moderate risk, and 881 (11.9%) as being at high risk. The adjusted risk of falling over the 4 subsequent years was 2.5 times as great for the moderate-risk group (hazard ratio (HR)=2.50, 95% confidence interval (CI)=2.16–2.89) and almost 4 times as great (HR=3.79, 95% CI=2.76–5.21) for the high-risk group as for the low-risk group. Risk of falling was greater for those who were prefrail (HR=1.22, 95% CI=1.05–1.41) and frail (HR=1.12, 95% CI=0.87–1.44) than for those who were robust.
Conclusion
STEADI score is a strong predictor of future falls. Addition of frailty status does not improve the ability of the STEADI measure to predict future falls.
