Analysis of Falls Efficacy Scale and Vulnerable Elders Survey as Predictors of Falls

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

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.

Geriatric falls: an enormous economic burden compared to firearms

Background

This study aimed to assess the medical costs, and the combined costs of fatal firearm injury and fatal falls during a 5 year period. While fatal firearm injury represents a significant public health concern, the healthcare community is faced with the significant challenge of fatal falls, particularly in light of the elderly population growth.

Methods

Data were exported from the Web-based Injury Statistics Query and Reporting System database for fatal firearm and falls in patients aged between 15-85 years-old. The primary outcome was medical cost and the secondary outcome was combined costs (combination of medical costs and value of statistical life).

Results

The medical cost of fatal falls was significantly higher in 2015-2020 in all age groups. The combined cost was significantly higher in fatal firearm injury overall. We found the combined cost was higher in fatal falls after 2019 for patients in the 45-85+ age range. During 2015-2019, the percentage of fatal falls had a significant increase in all age ranges, with a rise in the slope in 2019 for patients over 65 years. The annual percent change (APC) for the proportion of fatal falls increased from 2015 to 2020, there was a significant increase in the slope after 2019 (2.81% APC before 2019 vs 6.95% after 2019).

Conclusion

Geriatric fatal falls have significantly higher medical costs compared with fatal firearm injury. The combined cost for fatal falls exceeded fatal firearm injury after 2019 which highlights the increasing socioeconomic burden of an aging population.

Level of evidence

Screening for Risk of Fall-Related Inpatient Trauma in a US Acute Care Setting

Introduction Falls during hospitalization are a leading cause of preventable trauma-related injuries. Factors associated with fall risk include an unfamiliar environment, changes in health status, and efficacy based on the home environment. Assessing fall efficacy with an individualized prevention plan can decrease falls. The primary aim of this study was to estimate the effect of implementing a fall efficacy screening and intervention on reducing patient falls. Methods The study utilized a quasi-experimental, cross-sectional design with a convenience sample of patients admitted to an in-patient adult medical unit within a community hospital over a twelve-month period. Sampling times included pre-implementation, immediately post-implementation, and a second post-implementation phase. The intervention consisted of an admission fall efficacy screening tool and an individualized educational initiative. Statistical analysis included descriptive statistics of central tendency and dispersion, along with inferential statistics using independent sample t-tests, chi-square tests, correlations, and binary logistic regression. Results Among the study participants (n=2,074), the total sample had an average age of 67.7 (+/- 17.4) years and had mean scores of 13.3 (6.9) on the Short Falls Efficacy Scale-International and 51.8 (20.3) on the Morse Fall Scale. Fifty-two percent of the study population were female; 16.2% of the patients were diagnosed with cerebrovascular accident (CVA) or CVA-like symptoms. Fall rates decreased with a rate of change of -4.15% after efficacy screening and intervention. Males demonstrated higher efficacy in avoiding falls compared to females (t(828) = 3.369, p <0.001). Patients with a CVA diagnosis demonstrated higher efficacy scores compared to non-CVA patients (t(2071) = -3.348, p <0.001). FES risk groups (OR of 5.632, 95% CI (2.171-7.892)) and age over 65 (OR 1.21, 95% CI (1.006-1.442)) were significant predictors of a fall when patients with a primary CVA diagnosis were omitted from the sample (p= 0.022 and 0.046 respectively). Conclusion The findings suggest that efficacy screening may be associated with decreased falls for acute care non-CVA inpatient populations over 65 years of age. Further research into the predictive utility of fall efficacy screening in acute care CVA and non-CVA hospitalized patient populations aged 65 years and above is recommended.

Evaluation of a Fall Prevention Program to Reduce Fall Risk and Fear of Falling Among Community-Dwelling Older Adults and Adults with Disabilities

Purpose

The overarching goal of the program evaluation was to determine the reach and impact of the District-funded Safe At Home (SAH) modification program in reducing falls, fall injuries, and fear of falls among community-dwelling older adults and adults with disabilities. The SAH program has served over 6000 adults since 2016, the majority of whom are women (79%) and over age 60 (92%).

Materials and Methods

Letters were mailed in September 2022 to clients (n=492) who had home modifications completed between October 2021-March 2022 inviting them to participate in a brief phone survey about program satisfaction, falls, fall location, and severity. The validated Fall Efficacy Scale (FES) was administered pre (at first visit), post (at last visit), and during the phone survey (within 6 months to 1 year of program completion) to assess fear of falling. The response rate was 55% (n=241).

Results

Older adults (n=219) and adults with disabilities (n=22) reported high program satisfaction. Most clients, 79%, did not report a fall since the completion of the home modifications. The majority of falls reported, 76%, occurred inside the home. The average evaluation FES score was 32.5 (SD=22.6, range 10-100), indicating relatively low fear of falling. Higher FES scores were associated with a greater likelihood of reporting a fall (r=0.44, p < 0.001, n=51) and older age (r = 0.17, p < 0.01). FES scores were not related to gender. Evaluation FES scores were significantly lower than the pre-FES scores, indicating a reduction in fear of falling and positive impact of the home modifications (T(107) = 5.14, p < 0.001).

Conclusion

The client-centered SAH program demonstrates significant reductions in falls, fear of falling, and high satisfaction among clients. Recommendations include program expansion to offer other evidence-based components to reduce falls and support safe aging in place.

Number of medications and polypharmacy are associated with risk of fall in Saudi community-dwelling adults

Background

This study primarily aimed to examine the association between the number of medications and polypharmacy with fall history and fear of falling among Saudi community-dwelling adults aged 50 years and older. A secondary objective was to determine the cutoff score of the number of medications associated with a history of falls within this population.

Methods

This cross-sectional study included community-dwelling adults aged ≥ 50 years living in Saudi Arabia. The participants were asked to report any history of falls in the past 12 months; the Falls Efficacy Scale (FES-I) was used to measure the fear of falling. The number of medications was obtained by interviewing the participants and was recorded as a number. Polypharmacy was defined as the use of ≥ 4 medications. Binary logistic regression and linear regression analyses were performed. Receiver operator characteristics and area under the curve were used to determine the cut-off scores for the number of medications that distinguished fallers from non-fallers.

Results

A total of 206 participants (96 women) were included. The prevalence of falls was 12.6 %. Number of medications was associated with a history of falls (OR 1.55, 95 % CI [1.16, 2.07], p = 0.003) after adjustments for age, sex, body mass index, education, employment status, marital status, and number of chronic conditions. Polypharmacy was associated with a history of falls (OR 9.06, 95 % CI [2.56, 32.04], p = 0.012) after adjusting for covariates. Neither the number of medications nor polypharmacy was associated with fear of falling, as measured by FES-I. The number of medications with a cutoff of ≥ 2 or more medications was associated with a history of fall with a sensitivity of 69.23 % and specificity of 66.67 %.

Conclusion

This study found that the number of medications and polypharmacy were associated with a history of falls among community-dwelling adults aged ≥ 50 years. A cutoff score was identified of 2 or more medications that distinguished fallers from non-fallers in this population. This cut-off score was below the polypharmacy threshold.

A Pilot Study to Validate a Wearable Inertial Sensor for Gait Assessment in Older Adults with Falls

The high prevalence of falls and the enormous impact they have on the elderly population is a cause for concern. We aimed to develop a walking-monitor gait pattern (G-STRIDE) for older adults based on a 6-axis inertial measurement (IMU) with the application of pedestrian dead reckoning algorithms and tested its structural and clinical validity. A cross-sectional case–control study was conducted with 21 participants (11 fallers and 10 non-fallers). We measured gait using an IMU attached to the foot while participants walked around different grounds (indoor flooring, outdoor floor, asphalt, etc.). The G-STRIDE consisted of a portable inertial device that monitored the gait pattern and a mobile app for telematic clinical analysis. G-STRIDE made it possible to measure gait parameters under normal living conditions when walking without assessing the patient in the outpatient clinic. Moreover, we verified concurrent validity with convectional outcome measures using intraclass correlation coefficients (ICCs) and analyzed the differences between participants. G-STRIDE showed high estimation accuracy for the walking speed of the elderly and good concurrent validity compared to conventional measures (ICC = 0.69; p < 0.000). In conclusion, the developed inertial-based G-STRIDE can accurately classify older people with risk to fall with a significance as high as using traditional but more subjective clinical methods (gait speed, Timed Up and Go Test).
