A Scoping Review of Fall-Risk Screening Tools in the Emergency Department for Future Falls in Older Adults.

Abstract

Background: Approximately one-third of adults over the age of 65 experience falls annually, with half resulting in injury. Peak bodies have recommended the use of fall-risk screening tools in the emergency department (ED) to identify patients requiring in-depth assessment and potential fall-prevention intervention. This study aimed to examine the scope of published studies on fall-risk screening tools used in the ED and evidence of associations between screening and future falls.

Summary: PubMed, Embase and CINAHL were searched for peer-reviewed journal articles published since 2012 that examined one or more screening tools to identify patient-level fall risk. Eligible studies described fall-risk tools applied in the ED. Data extracted included sample information, variables measured, and statistical analysis. Sixteen studies published since 2012 were included after full-text review. Fourteen unique screening tools were found. Eight tools were fall-risk screening tools, one tool was a functional screening tool, one tool was a frailty-screening tool, two tools were rapid physical tests, one tool was a trauma triage tool, and one tool was a component of a health-related quality-of-life measure. Studies that evaluated prognostic performance (n = 11) generally reported sensitivity higher than specificity. Previous falls (n = 10) and high-risk medications (n = 6) were consistently associated with future falls. Augmentation with additional variables from the electronic medical record (EMR) improved screening tool prognostic performance in one study.

Key messages: Current evidence on the association between the use of fall-risk screening tools in the ED for future falls consistently identifies previous falls and high-risk medications as associated with future falls. Comparison between tools is difficult due to different evaluation methods and different covariates measured. Augmentation of fall-risk screening using the EMR in the ED requires further investigation.
