Fall-related emergency department visits and hospitalizations among community-dwelling older adults: examination of health problems and injury characteristics

Economic modelling of fall prevention interventions delivered by community emergency medical services: a decision-tree analysis

BACKGROUND

Fall prevention interventions delivered by specially trained emergency medical services (EMS) clinicians in the homes of patients at high risk for falls have been shown to prevent recurrent falls. However, the cost of implementing this 'community EMS' approach to fall prevention is a barrier to widespread adoption. The objective of this study was to assess whether a community EMS fall prevention intervention results in overall cost savings for the healthcare system.

METHODS

We performed a cost-effectiveness analysis using a decision-tree model of possible outcomes after an index fall in a simulated population of community-dwelling adults aged ≥65 over a 1-year time horizon. Transition probabilities and costs were obtained through literature review. The intervention, delivered in patients' homes by specialised EMS clinicians, consisted of environmental modifications, fall prevention education, referral to occupational and physical therapy, and coordination with the patient's primary care physician. We compared the mean healthcare expenditures per patient among those receiving and not receiving the fall prevention intervention.

RESULTS

The intervention would result in a net cost savings of $964 per patient compared with no intervention, with an incremental cost-effectiveness ratio of -$22 174 per fall prevented (lower cost and more effective). Holding other variables constant, the programme would remain cost-saving if the effectiveness decreased to a 26% reduction in falls or the programme cost increased to $1634 per patient.

CONCLUSIONS

In this economic modelling analysis, a multifactorial fall prevention intervention delivered by community EMS was cost saving to the healthcare system. Healthcare payors should provide financial support and reimbursement for these programmes.

Evaluation of Older Adults in the Emergency Department Following a Fall

Falls are an important source of morbidity and mortality for older adults. The emergency department (ED) evaluation of an older patient who presents after a fall should include an assessment of events contributing to the acute fall, injuries sustained from it, as well as an underlying falls syndrome. ED measures and referrals to appropriate outpatient services on discharge can help ensure patients receive care and services that can help reduce future falls.

Mobile health (mHealth) technologies for fall prevention among older adults in low-middle income countries: bibliometrics, network analysis and integrative review

Introduction

mHealth technologies offer promising solutions to reduce the incidence of falls among older adults. Unfortunately, publications on their application to Low-Middle Income Countries (LMIC) settings have not been collectively examined.

Methods

A triadic research design involving bibliometrics, network analysis, and model-based integrative review was conducted to process articles (n = 22) from 629 publications extracted from major databases using keywords related to mHealth, falls prevention, and LMIC. The web-based application Covidence and stand-alone VosViewer software were used to process data following previously published review standards.

Results

Published articles in the field feature multidisciplinary authorships from multiple scholars in the domains of health and technology. Network analysis revealed the most prominent stakeholders and keyword clusters related to mHealth technology features and applications in healthcare. The papers predominantly focused on the development of mHealth technology, usability, and affordances and less on the physiologic and sociologic attributes of technology use. mHealth technologies in low and middle-income countries are mostly smartphone-based, static, and include features for home care settings with fall detection accuracy of 86%-99.62%. Mixed reality-based mobile applications have not yet been explored.

Conclusion

Overall, key findings and information from the articles highlight a gradually advancing research domain. Outcomes reinforce the need to expand the focus of mHealth investigations to include emerging technologies, update current technology models, create a more human-centered technology design, test mHealth technologies in the clinical setting, and encourage continued cooperation between and among researchers from various fields and environments.

Association of Coprescribing of Gabapentinoid and Other Psychoactive Medications With Altered Mental Status and Falls in Adults Receiving Dialysis

RATIONALE & OBJECTIVE

Prescribing psychoactive medications for patients with kidney disease is common, but for patients receiving dialysis some medications may be inappropriate. We evaluated the association of coprescribing gabapentinoids and other psychoactive potentially inappropriate medications (PPIMs) (eg, sedatives or opioids) with altered mental status (AMS) and falls and whether the associations are modified by frailty.

STUDY DESIGN

Observational cohort study.

SETTING & PARTICIPANTS

Adults receiving dialysis represented in the US Renal Data System who had an active gabapentinoid prescription and no other PPIM prescriptions in the prior 6 months.

EXPOSURE

PPIM coprescribing, or the presence of overlapping prescriptions of a gabapentinoid and≥1 additional PPIM.

OUTCOME

Acute care visits for AMS and injurious falls.

ANALYTICAL APPROACH

Prentice-Williams-Petersen Gap Time models estimated the association between PPIM coprescribing and each outcome, adjusting for demographics, comorbidities, and frailty, as assessed by a validated frailty index (FI). Each model tested for interaction between PPIM coprescribing and frailty.

RESULTS

Overall, PPIM coprescribing was associated with increased hazard of AMS (HR, 1.66 [95% CI, 1.44-1.92]) and falls (HR, 1.55 [95% CI, 1.36-1.77]). Frailty significantly modified the effect of PPIM coprescribing on the hazard of AMS (interaction P=0.01) but not falls. Among individuals with low frailty (FI=0.15), the HR for AMS with PPIM coprescribing was 2.14 (95% CI, 1.69-2.71); for individuals with severe frailty (FI=0.34), the hazard ratio for AMS with PPIM coprescribing was 1.64 (95% CI, 1.42-1.89). Individuals with PPIM coprescribing and severe frailty (FI=0.34) had the highest hazard of AMS (HR, 3.22 [95% CI, 2.55-4.06]) and falls (HR, 2.77 [95% CI, 2.27-3.38]) compared with nonfrail individuals without PPIM coprescribing.

LIMITATIONS

Outcome ascertainment bias; residual confounding.

CONCLUSIONS

Compared with gabapentinoid prescriptions alone, PPIM coprescribing was associated with an increased risk of AMS and falls. Clinicians should consider these risks when coprescribing PPIMs to patients receiving dialysis.

PLAIN-LANGUAGE SUMMARY

Among people on dialysis, gabapentinoids may lead to confusion and falls. Often they are prescribed with other sedatives drugs or opioids, which can increase these risks. This study of adults with kidney failure receiving maintenance dialysis in the United States found that those who were prescribed both gabapentinoids and other psychoactive drugs were more likely to have confusion and falls compared with those who only took gabapentinoids. These relationships were seen at all levels of frailty although the relative risk of confusion related to an additional psychoactive drug was somewhat lower in the setting of greater frailty. Clinicians should consider elevated risks of confusion and falls when prescribing psychoactive drugs to patients receiving dialysis who are also prescribed gabapentinoids.

Human motor performance assessment with lower limb exoskeletons as a potential strategy to support healthy aging-a perspective article

With increasing age, motor performance declines. This decline is associated with less favorable health outcomes such as impaired activities of daily living, reduced quality of life, or increased mortality. Through regular assessment of motor performance, changes over time can be monitored, and targeted therapeutic programs and interventions may be informed. This can ensure better individualization of any intervention approach (e.g. by considering the current motor performance status of a person) and thus potentially increase its effectiveness with regard to maintaining current performance status or delaying further decline. However, in older adults, motor performance assessment is time consuming and requires experienced examiners and specific equipment, amongst others. This is particularly not feasible in care facility/nursing home settings. Wearable robotic devices, such as exoskeletons, have the potential of being used to assess motor performance and provide assistance during physical activities and exercise training for older adults or individuals with mobility impairments, thereby potentially enhancing motor performance. In this manuscript, we aim to (1) provide a brief overview of age-related changes of motor performance, (2) summarize established clinical and laboratory test procedures for the assessment of motor performance, (3) discuss the possibilities of translating established test procedures into exoskeleton-based procedures, and (4) highlight the feasibility, technological requirements and prerequisites for the assessment of human motor performance using lower limb exoskeletons.

Fall Risk and Medication Use Near End of Life Among Adults With Chronic Obstructive Pulmonary Disease

Background

Falls are frequent among people with chronic obstructive pulmonary disease (COPD) and are associated with increased morbidity, mortality, and health care costs. Understanding modifiable medication factors that contribute to fall risk is an important step to developing fall prevention strategies for this highly susceptible group.

Methods

This is a retrospective cohort study using electronic health record data from a single health system linked to Washington State death certificates of adults ages 40 or older who died between 2014-2018 with COPD. We identified demographics, comorbidities, fall-risk increasing drug (FRID) burden, and the occurrence of injurious falls within the 2 years prior to the date of death. We defined injurious falls using published algorithms of the International Classification of Diseases codes.

Results

Of 8204 decedents with COPD, 2454 (30%) had an injurious fall in the 2 years before death, and FRID use was common among 65%. A higher percentage of patients with falls received prescriptions for anticonvulsants (35% versus 26%), antipsychotics (24% versus 13%), atypical antidepressants (28% versus 19%), and tricyclic antidepressants (10% versus 5%) versus those without a fall. In multivariable logistic regression, after adjusting for confounders, FRID burden was associated with greater odds of an injurious fall (odds ratio 1.07 [95% confidence interval 1.04-1.09]).

Conclusion

Our findings highlight an opportunity for collaboration between pharmacists, pulmonologists, and patients to develop new processes to potentially deprescribe and optimize the use of FRIDs among patients with COPD to increase safety.

Moving together-benefits of a 12-week online dance training intervention on static and dynamic postural stability and gait speed in older women: an exploratory pre-post study

Background

Physical inactivity negatively affects gait performance and postural stability in older adults resulting in a higher risk of fall accidents. Previous research has shown that in-person dance training improves various aspects of balance and lower-extremity function, however, little is known about the potential benefits of dance training delivered online on variables used for fall risk stratification in older adults. We aimed to explore the benefits of a 12-week online dance training intervention on static and dynamic postural stability and gait speed in older women.

Methods

Forty-five older adults (44 women) were included in this exploratory pre-post study. The 12-week dance intervention consisted of two weekly 60-min classes in contemporary (improvisation) and salsa dance delivered online through Zoom video calls. Static and dynamic postural stability was assessed using the center of pressure (CoP) area and velocity (force platform), and the Mini Balance Evaluation Systems Test (Mini-BESTest), respectively. 10-m gait speed was measured using photo gates. Before and after comparisons were performed using paired sample t-tests.

Results

Thirty-two older women completed the study. There were no significant changes for static postural stability assessed by CoP area or velocity (P ≥ 0.218, Cohen d ≤ 0.234). The Mini-BESTest total score was significantly improved at post-intervention (23.88 ± 3.01) compared to baseline (22.56 ± 1.41, P = 0.007, d = 0.52). 10-m gait speed was significantly faster at post-intervention (1.68 ± 0.25 m/s) compared to baseline (1.57 ± 0.22 m/s, P < 0.001, d = 0.737).

Discussion

Although some caution is needed due to the uncontrolled study design, the results indicate that online dance training has a small effect on static postural stability but may be beneficial for gait speed and in particular dynamic postural control among older women. While the absolute increase in gait speed suggests limited clinical relevance, the change in Mini-BESTest score may reflect a clinically meaningful enhancement of dynamic postural control.

Protocol for a home-based self-delivered prehabilitation intervention to proactively reduce fall risk in older adults: a pilot randomized controlled trial of transcranial direct current stimulation and motor imagery

BACKGROUND

Several changes occur in the central nervous system with increasing age that contribute toward declines in mobility. Neurorehabilitation has proven effective in improving motor function though achieving sustained behavioral and neuroplastic adaptations is more challenging. While effective, rehabilitation usually follows adverse health outcomes, such as injurious falls. This reactive intervention approach may be less beneficial than prevention interventions. Therefore, we propose the development of a prehabilitation intervention approach to address mobility problems before they lead to adverse health outcomes. This protocol article describes a pilot study to examine the feasibility and acceptability of a home-based, self-delivered prehabilitation intervention that combines motor imagery (mentally rehearsing motor actions without physical movement) and neuromodulation (transcranial direct current stimulation, tDCS; to the frontal lobes). A secondary objective is to examine preliminary evidence of improved mobility following the intervention.

METHODS

This pilot study has a double-blind randomized controlled design. Thirty-four participants aged 70-95 who self-report having experienced a fall within the prior 12 months or have a fear of falling will be recruited. Participants will be randomly assigned to either an active or sham tDCS group for the combined tDCS and motor imagery intervention. The intervention will include six 40-min sessions delivered every other day. Participants will simultaneously practice the motor imagery tasks while receiving tDCS. Those individuals assigned to the active group will receive 20 min of 2.0-mA direct current to frontal lobes, while those in the sham group will receive 30 s of stimulation to the frontal lobes. The motor imagery practice includes six instructional videos presenting different mobility tasks related to activities of daily living. Prior to and following the intervention, participants will undergo laboratory-based mobility and cognitive assessments, questionnaires, and free-living activity monitoring.

DISCUSSION

Previous studies report that home-based, self-delivered tDCS is safe and feasible for various populations, including neurotypical older adults. Additionally, research indicates that motor imagery practice can augment motor learning and performance. By assessing the feasibility (specifically, screening rate (per month), recruitment rate (per month), randomization (screen eligible who enroll), retention rate, and compliance (percent of completed intervention sessions)) and acceptability of the home-based motor imagery and tDCS intervention, this study aims to provide preliminary data for planning larger studies.

Bayesian semi-parametric inference for clustered recurrent events with zero inflation and a terminal event

Recurrent events are common in clinical studies and are often subject to terminal events. In pragmatic trials, participants are often nested in clinics and can be susceptible or structurally unsusceptible to the recurrent events. We develop a Bayesian shared random effects model to accommodate this complex data structure. To achieve robustness, we consider the Dirichlet processes to model the residual of the accelerated failure time model for the survival process as well as the cluster-specific shared frailty distribution, along with an efficient sampling algorithm for posterior inference. Our method is applied to a recent cluster randomized trial on fall injury prevention.

Chronic pain in older adults with disabilities is associated with fall-related injuries: a prospective cohort study

PURPOSE

Previous studies have shown an association between chronic pain and the occurrence of falls in community-dwelling older adults; however, the association between chronic pain and fall-related injuries in older adults with disabilities is unclear. This study aimed to determine the association between chronic pain and fall-related injuries in older adults with disabilities.

METHODS

This 24-month prospective cohort study included older adults aged 65 years or older using Japanese long-term care insurance services. Chronic pain, defined as "pain that has persisted for more than three months to date," was assessed using a face-to-face questionnaire. Fall-related injuries, defined as "injuries requiring hospitalization or outpatient treatment due to a fall," were assessed using a fall calendar. Data were analyzed using a Cox proportional hazards model, with fall-related injury as the dependent variable, chronic pain as the independent variable, and confounders as covariates.

RESULTS

Among 133 included participants, 15 experienced fall-related injuries. After adjusting for age and sex as covariates, chronic pain was significantly associated with fall-related injuries (hazard ratio: 5.487, 95% confidence interval: 1.211-24.853, p = 0.027).

CONCLUSIONS

Chronic pain was associated with fall-related injuries in older adults with disabilities. In this population, a greater focus should be placed on treating chronic pain to reduce the occurrence of falls.

The factors influencing patient safety management as perceived by emergency department nurses: A qualitative study

AIM

One of the most important, unpredictable and stressful areas in hospitals is the emergency department (ED) where seconds are crucial for providing immediate care and saving the patients' lives. Therefore, the present study aimed to identify the factors which impact the patient safety management as perceived by the ED nurses in Southern Iran.

DESIGN

This is a qualitative, descriptive study.

METHODS

The participants were 23 ED nurses selected via purposeful sampling who were asked to take part in an interview. Data were collected using semi-structured, individual, in-depth interviews and analysed via content analysis.

RESULTS

Analysis of the qualitative data yielded 4 themes and 12 subthemes. The four main themes were: negligence of safety standards and standard precautions, disregard of ethical principles, professional challenges and inefficient organizational management.

Cost of U.S emergency department and inpatient visits for fall injuries in older adults

BACKGROUND

Falls are a leading cause of injury and hospital readmissions in older adults. Understanding the distribution of acute treatment costs across inpatient and emergency department settings is critical for informed investment and evaluation of fall prevention efforts.

METHODS

This study used the 2016-2018 National Inpatient Sample and National Emergency Department Sample. Annual treatment cost of fall injury among adults 65 years and older was estimated from charges, applying cost-to-charge and professional fee ratios. Weighted multivariable generalized linear models were used to separately estimate cost for inpatient and emergency department (ED) setting by injury type and individual demographic and health characteristics after adjusting for payer and hospital level characteristics.

RESULTS

Older adults incurred an estimated 922,428 inpatient and 2.3 million ED visits annually due to falls with combined annual costs of $19.8 billion. Over half of inpatient visits for fall injury were for fracture. Notably, 23% of inpatient visits were for fractures other than hip fracture and 14% of inpatient visits were for multiple fractures with costs totaling $3.4 billion and $2.5 billion, respectively. Annual ED costs were driven by superficial injury totaling $1.5 billion. Cost of ED visits were higher for adults 85 years and older (adjusted cost ratio (aCR): 1.11, 95% Confidence Interval (CI)I: 1.11-1.12) and those with dementia (aCR: 1.14, 95% CI: 1.13-1.15). Higher inpatient and ED visit cost was also associated with high-energy falls and discharge to post-acute care.

CONCLUSION

The study found that more than 3 million older adults in the United States seek hospital care for fall injuries annually, a major concern given increasing capacity strain on hospitals and EDs. The $20 billion in annual acute treatment costs attributed to fall injury indicate an urgent need to implement evidence-based fall prevention interventions and underscores the importance of newly launched ED-based fall prevention efforts and investments in geriatric emergency departments.

The determination of sarcopenia in older adults using a practical measure

BACKGROUND

Many older adults are at risk of sarcopenia, a gradual loss of muscle mass affecting muscle strength and physical function, which can lead to adverse health consequences deteriorating their independence. However, the detection could be delayed due to the requirement of many measures, including a complex imaging modality. Thus, an exploration for a practical community- or home-based measure would be helpful to identify at-risk older adults and begin the timely management.

OBJECTIVE

To explore the ability of the upper limb loading during a seated push-up test (ULL-SPUT) to determine the presence of sarcopenia in community-dwelling older adults.

METHODS

Older adults (n= 110; 62 females, average age approximately 77 years) were cross-sectionally assessed for sarcopenia using standard measures (handgrip strength, appendicular skeletal muscle mass, and walking speed) and the ULL-SPUT.

RESULTS

Data from standard measures indicated that 44 participants had sarcopenia. The ULL-SPUT index of < 16.9 kg/m2 for females (sensitivity = 86%, specificity = 78%, area under the receiver operating characteristic curve [AUC] = 0.85) and < 19.7 kg/m2 for males (sensitivity = 73%, specificity = 69%, AUC = 0.83) could optimally identify participants with sarcopenia.

CONCLUSION

The ULL-SPUT index could be used to screen and monitor older adults with sarcopenia in various clinical, community, and home settings. This practical measure may be accomplished using a digital bathroom scale on a hard, even surface. Outcomes would identify an adult who should undergo further confirmation of sarcopenia through standard measures or the initiation of timely management to promote treatment effectiveness.

Purpose in Life and Risk of Falls: A Meta-Analysis of Cross-Sectional and Prospective Associations

Background and Aim: Purpose in life is an aspect of well-being that is associated with better health outcomes in older adulthood. We examine the association between purpose in life and likelihood of a recent fall and risk of an incident fall over time. Methods: Purpose in life and falls were reported concurrently and falls were reported again up to 16 years later in four established longitudinal studies of older adults (total N = 25,418). Results: A random-effects meta-analysis of the four samples indicated that purpose was associated with a 14% lower likelihood of having fallen recently at baseline (meta-analytic OR = 0.88, 95% CI [0.84-0.92]). Among participants who reported no falls at baseline (N = 15,632), purpose was associated with a nearly 10% lower risk of an incident fall over the up to 16-year follow-up (meta-analytic HR = 0.92, 95% CI [0.90-0.94]). These associations were independent of age, sex, race, ethnicity, and education, were not moderated by these factors, and persisted controlling for physical activity and disease burden. Conclusion and Recommendations: Purpose in life is a meaningful aspect of well-being that may be useful to identify individuals at risk for falling, particularly among individuals without traditional risk factors, and be a target of intervention to reduce fall risk.

The C-Brace® microprocessor controlled stance and swing orthosis improves safety, mobility, and quality of life at one year: Interim results from a prospective registry

Introduction

The C-Brace microprocessor-controlled stance and swing control orthosis has been shown to improve function, mobility, and quality of life. A systematic registry to gather long-term, real-world safety and effectiveness data in patients fit with a C-Brace has not been performed.

Methods

International multicenter registry. Patients undergoing routine C-Brace fittings were assessed at baseline and 1 year after fitting. Primary outcomes were fast walking speed (FWS) measured by 25-foot or 10-meter walk test, Timed Up and Go (TUG) and the Activity-specific Balance Confidence (ABC) Scale. Secondary and exploratory outcomes included the Patient-specific Functional Scale (PSFS), falls, pain, PROMIS Pain Interference (PI), and quality of life.

Results

48 subjects with 1-year baseline and follow up data were analyzed. With the C-Brace, FWS improved by + 0.26 ± 0.33 m/s (p < .0001), TUG by -8.1 ± 14.6 sec (p < .0001), and ABC by + 24.9 ± 25.8% (p < .0001). Mean falls reduced from 33 ± 77 to 3.0 ± 5.6 (p = .0005). PSFS increased by 3.60 ± 2.34 points (p < .0001). Outcomes for pain, PI and quality of life showed significant improvements with the C-Brace.

Conclusion

The C-Brace is an effective option to improve safety, mobility, and quality of life for patients needing a KAFO for ambulation.

Use of Physical Therapy and Subsequent Falls Among Patients With Dizziness in the US

Importance

Among adults who present for clinical evaluation of dizziness, there is a critical need to identify interventions, such as physical therapy (PT), to mitigate the risk of falls over time.

Objective

The primary objective was to examine the association between receipt of PT and falls requiring medical care within 12 months of presentation for dizziness. Secondary objectives included identification of factors associated with falls requiring medical care and factors associated with receipt of PT after presentation for dizziness.

Design, Setting, and Participants

This cross-sectional study examined US commercial insurance and Medicare Advantage claims from January 1, 2006, through December 31, 2015. In all, 805 454 patients 18 years or older with a new diagnosis of symptomatic dizziness or vestibular disorders were identified. Data were analyzed from October 1, 2021, to February 1, 2023.

Main Outcomes and Measures

Receipt of PT services and the incidence of falls requiring medical care were measured. The association between receipt of PT and falls that occurred 12 months after presentation for dizziness was estimated after accounting for presentation setting (outpatient clinic or emergency department), Charlson Comorbidity Index (CCI; with higher scores indicating greater morbidity), diagnosis code, and sociodemographic characteristics.

Results

A total of 805 454 patients presented for dizziness from 2006 through 2015 (median [range] age, 52 [18-87] years; 502 055 females [62%]). Of these patients, 45 771 (6%) received PT within 3 months of presentation for dizziness and 60 060 (7%) experienced a fall resulting in a medical encounter within 12 months after presentation for dizziness. In adjusted models, patients least likely to receive PT were female (adjusted odds ratio [AOR], 0.80; 95% CI, 0.78-0.81), those aged 50 to 59 years (AOR, 0.67 [95% CI, 0.65-0.70] compared with patients aged 18-39 years), and those with more comorbidities (AOR, 0.71 [95% CI, 0.70-0.73] for CCI ≥ 2 vs 0). Receipt of PT services within 3 months of presentation for dizziness was associated with a reduced risk of falls over the subsequent 12 months, with the greatest risk reduction found within 3 months after PT (AOR, 0.14 [95% CI, 0.14-0.15] at 3-12 months vs 0.18 [95% CI, 0.18-0.19] at 6-12 months and 0.23 [95% CI, 0.23-0.24] at 9-12 months).

Conclusions and Relevance

Results of this cohort study suggest that receipt of PT after presentation for dizziness was associated with a reduction in fall risk during the subsequent 12 months; thus, timely PT referral for dizziness may be beneficial for these patients. Future research, ideally with a clinical trial design, is needed to explore the independent impact of PT on subsequent falls for adults with dizziness.

Exploring Population Characteristics and Recruitment Challenges in Older People Experiencing Falls at Home without Hospitalization or with an Emergency Department Visit: Insights from the RISING-DOM Experience

Background

An increasing number of falls among community-living older adults are reported in emergency calls. Data on evidence of appropriate fall prevention interventions are limited and challenges in recruiting this population in randomized trials are acknowledged.

Purpose

The main aim of this study was to provide demographic data, circumstance and fall-related outcomes of the population in the RISING-DOM study [Impact d'une évaluation des facteurs de RISque de chute et d'une prise en charge personnalisée, sur la mortalité et l'institutionnalisation, après INtervention du SAMU chez la personne âGée à DOMicile], a multicenter, randomized interventional trial involving community-dwelling older adults who have experienced a fall at home and were not hospitalized. Additionally, the challenges of remote recruitment in this population were discussed.

Patients and Methods

Participants were identified through the Occitania Emergency Observatory database. Participant recruitment and data collection were performed through telephone interviews (October 2019-March 2022). Additionally, a sample survey of Emergency Medical Services calls was carried out.

Results

Out of the 1151 individuals screened, a total of 951 participants were included in the trial follow-up, resulting in an acceptance rate of 82.62%. The screening delay was extended due to the COVID-19 pandemic. Recruiting difficulties were mainly related to identifying potential participants, unavailable contact information and unreachability. Participants' mean age was 84.1 years, 65.8% were women, and 44.3% lived alone. Pain was the most frequent outcome (53%). In the previous year, 73.5% of participants reported experiencing a fall, with 66.7% of those falls requiring assistance from Emergency Medical Services (EMS). Nearly, 40% did not take proactive steps to prevent future falls and walking aids (79.8%) were the most common preventive action.

Conclusion

Indicators of a high-risk group of falls have been identified underscoring the need for appropriate fall interventions in the target population. Challenges of large sampling for randomized fall prevention trials were provided.

Post-Hospital Falls Among the Older Population: The Temporal Pattern in Risk and Healthcare Burden

OBJECTIVES

Older adults are prone to falls following hospital discharge, resulting in healthcare utilization and costs. The fall risk might change over time after discharge. To fill research gaps in this area, this study examined the temporal pattern in incidence and healthcare burden of post-hospital falls in older adults.

DESIGN

A territory-wide retrospective cohort study was conducted.

SETTING AND PARTICIPANTS

Participants were Hong Kong adults aged ≥65 years and discharged from hospitals between January 2007 and December 2017.

METHODS

The participants were followed for 12 months to identify fall-related inpatient episodes, accident and emergency department (AED) visits, and mortality after discharge. The post-hospital falls were further analyzed in 2 subcategories (1) only requiring AED visits and (2) requiring hospitalization. The incidence rate and faller incidence proportion for total falls and subcategories during the different periods were examined. The corresponding healthcare utilization and costs were calculated.

RESULTS

Among the 606,392 older adults discharged from hospitals during the study period, 28,593 individuals (4.7%) experienced at least 1 post-hospital fall within 12 months, resulting in a total of 33,158 falls (57 per 1000 person-years). Out of post-hospital falls presenting to hospitals, one-third only required AED visits, and two-thirds required hospitalization. The fall incidence rate peaked in the first 3 weeks after discharge and gradually decreased to a stable level from the fourth to ninth week. The annual healthcare costs related to post-hospital falls exceeded USD 28.9 million in older adults, with the mean cost per faller and fall being USD 11,129 and USD 9596.

CONCLUSIONS AND IMPLICATIONS

The fall-related healthcare utilizations after discharge impose a substantial economic burden on older adults. During the first 9 weeks, particularly the first 3 weeks, older adults were at high risk of falling. The efforts on resource allocation for fall prevention are suggested to prioritize this period.

Potential Factors Associated with Healthcare Utilization for Balance Problems in Community-Dwelling Adults within the United States: A Narrative Review

Falls are the leading cause of mortality and chronic disability in elderly adults. There are effective fall prevention interventions available. But only a fraction of the individuals with balance/dizziness problems are seeking timely help from the healthcare system. Current literature confirms the underutilization of healthcare services for the management of balance problems in adults, especially older adults. This review article explores factors associated with healthcare utilization as guided by the Andersen Healthcare Utilization Model, a framework frequently used to explore the factors leading to the use of health services. Age, sex, race/ethnicity, BMI, and comorbidities have been identified as some of the potential predisposing factors; socioeconomic status, health insurance, and access to primary care are the enabling and disabling factors; and severity of balance problem, perceived illness, and its impact on daily activities are the factors affecting need for care associated with healthcare utilization for balance or dizziness problems. Knowledge about these barriers can help direct efforts towards improved screening of vulnerable individuals, better access to care, and education regarding effective fall prevention interventions for those who are at risk for underutilization. This can aid in timely identification and management of balance problems, thereby reducing the incidence of falls.

One Step at a Time: Improving Gait Speed Measurement in a Geriatric Medicine Clinic

(1) Background: Mobility assessment is a key component of the assessment of an older adult as a part of the Age-Friendly Health System (AFHS) "geriatric 4Ms" framework. Several validated tools for assessing mobility and estimating fall risk in older adults are available. However, they are often under-utilized in daily practice even in specialty geriatric medicine care settings. We aimed to increase formal mobility assessment with brief gait speed measurement in a geriatric medicine outpatient clinic using phased change interventions. (2) Methods: This quality improvement (QI) initiative was conducted in a single outpatient geriatric medicine clinic. All clinic attendees who could complete a gait speed measurement were eligible for inclusion. The outcome measure was the completion of a 4 m gait speed. Several change interventions were implemented on a phased basis using the Model for Improvement methodology during the period from December 2018 to March 2020. Statistical process control charts were used to record gait speed measurements and detect non-random shifts. (3) Results: During this QI initiative, 80 patients were seen, accounting for 142 clinic visits. In response to change interventions, gait speed measurement at clinic visits increased from a median of 25% of visits to 67% by March 2020. (4) Conclusions: Adopting an AFHS care model is an urgent and challenging task to improve the quality of care for older adults. This initiative details how to effectively incorporate a brief, validated assessment of mobility using gait speed measurement into every geriatric medicine outpatient visit and progresses implementation of the AFHS "geriatric 4Ms". Mobility assessment can aid in identifying older adults at increased fall risk.

Preventing falls at home among people with intellectual disabilities: A scoping review

BACKGROUND

Falls are common among people with intellectual disabilities. Many falls happen within the home. Our scoping review aimed to identify evidence for falls-risk factors and falls-prevention interventions for this population.

METHOD

We conducted a multi-database search to identify any type of published study that explored falls-risk factors or falls-prevention interventions for people with intellectual disabilities. Following a process of (i) title & abstract and (ii) full-text screening, data was extracted from the included studies and described narratively.

RESULTS

Forty-one studies were included. Risks are multifactorial. There was limited evidence of medical, behavioural/psychological, or environmental interventions to address modifiable risk factors, and no evidence of the interventions' cost-effectiveness.

CONCLUSIONS

Clinically and cost effective, acceptable and accessible falls-prevention pathways should be available for people with intellectual disabilities who are at risk of falls from an earlier age than the general population.

Association between toileting and falls in older adults admitted to the emergency department and hospitalised: a cross-sectional study

OBJECTIVES

This study aimed to explore the potential risk factors associated with toileting-related falls in community-dwelling older adults who presented to the emergency department and were subsequently hospitalised.

DESIGN

This was a cross-sectional study.

SETTING AND PARTICIPANTS

This study was conducted in two teaching hospitals in Shanghai, China between October 2019 and December 2021 among community-dwelling adults aged ≥60 years.

METHODS

In-person interviews, physical assessment and medical record review were performed to collect data on the characteristics and risk factors of falls. Associations of toileting-related falls with demographic characteristics and geriatric syndromes were examined using logistic regression models.

MAIN OUTCOME MEASURES

Potential risk factors for toileting-related falls.

RESULTS

This study included 419 older patients with a mean age of 73.8±9.7 years. Among 60 (14.3%) patients with toileting-related falls (mean age: 78.8±9.2 years), 63.3% of toileting-related falls, mainly occurred between 00:00 and 05:59 hours, compared with 17.3% of non-toileting-related falls, which primarily occurred during the daytime. The rate of recurrent falls (35%) was significantly higher in the toileting-related falls group than in the non-toileting-related falls group (21.2%) (p=0.02). Logistic regression showed that visual impairment (OR 2.7, 95% CI 1.1 to 7.1), cognitive impairment (OR 3.3, 95% CI 1.3 to 8.4), gait instability (OR 3.1, 95% CI 1.1 to 8.8) and urinary incontinence (OR 3.4, 95% CI 1.2 to 9.9) were strongly associated with toileting-related falls. Twenty-three (38.3%) patients in the toileting-related falls group had moderate and severe injuries, compared with 71.7% in the non-toileting-related falls group (p<0.05).

CONCLUSIONS

This study revealed that patients who reported toileting-related falls were more likely to have cognitive impairment, urinary incontinence, gait instability, visual impairment than patients who fell during other activities. Social and healthcare professionals should prioritise the management of toileting activities in older patients and provide targeted interventions to those in the high-risk group.

Comorbid pain and falls among Chinese older adults: the association, healthcare utilization and the role of subjective and objective physical functioning

BACKGROUND

Pain and falls are significant disabling health conditions which cause substantial economic burdens on older adults and their families. Physical functioning (both subjective and objective) might play a significant role in older adults' pain and falls. In this study we aimed to examine: (1) the relationship between pain and falls among Chinese older adults; (2) pain-fall status (i.e., comorbid pain-fall, pain-only, fall-only, and neither-pain-nor-fall) in relation to healthcare utilization; and (3) whether physical functioning measured either subjectively or objectively would contribute differently to the pain intensity and to the occurrence of falls.

METHODS

We used a nationally-representative sample of older adults from the 2011-2012 baseline survey of the China Health and Retirement Longitudinal Study (N = 4,461, aged 60-95 years). Logistic, linear, and negative binomial models adjusted for demographic variables were used in the analysis.

RESULTS

Overall, 36% of older adults reported pain, 20% had fall occurrences, and 11% had comorbid pain and falls. Pain intensity was significantly associated with falls. Individuals in groups of pain-only, fall-only, and comorbid pain-fall reported significantly higher healthcare utilization, that is, more frequent inpatient care and doctor visits than those in the neither-pain-nor-fall group. Subjective, not objective, physical functioning was associated with pain and falls.

CONCLUSION

Pain and falls are significantly associated with each other, and both can lead to increased healthcare utilization. Compared to objective physical functioning, subjective physical functioning is more likely to correlate with pain and falls, suggesting that self-reported physical status should be considered when designing pain-fall preventive strategies.

The Effect of Age and Fall History on Lower Extremity Neuromuscular Function During Descent of a Single Transition Step

Despite the higher injury rate of falls on steps versus level ground, few studies have examined the influence of age and fall history on step descent. The purpose of this study was to determine the lead and trail limb neuromuscular function (peak joint moments and powers, electromyographic activity) differences between young females (n = 15) and older females with (n = 15) and without (n = 15) a fall history while descending a single step. Trail limb moments and powers did not differ between groups. Lead limb sagittal plane powers at the hip and knee were greater in the young adults. Electromyographic co-activation levels (knee and ankle) were not significantly different between groups. However, peroneal activation was greater in the older groups, which may have assisted in stabilizing the ankle joint in lieu of increased co-activation at the ankle. These results demonstrate consideration of step descent is important in working with older women at risk of falls.

Evaluation of therapy in traumatic elderly falls to return autonomy and functional status

Background

Traumatic falls among the elderly (≥ 65 years old) are the leading cause of injury, morbidity and mortality are increasing with rising medical costs.

Methods

This is a retrospective medical record review of elderly mechanical fall patients (288 patients) admitted to an American College of Surgeons level II trauma center from January 2016 to January 2021. Demographics and comorbidities were determined, and physical/occupational therapy used to predict subsequent fall readmissions.

Results

Out of 288 patients, 243 received therapy with 45 readmissions for subsequent falls. Age (P = .016), body mass index (P = .035), previous falls (P = .003), walker/cane use (P = .039), and dementia (P = .038) were predictive of readmission. Therapy was shown to benefit patients, but deferred therapy sessions were shown to be associated with prolonged hospitalization.

Conclusion

Directed therapy may improve functionality and return autonomy to elderly mechanical fall patients admitted to trauma services.

•

Elderly fall patient evaluation after falls can predict need for therapy.

•

Directed therapy can benefit and potentially prevent recurrence of falls.

•

Deferrals of therapy are associated with prolonged hospital stays.

App-Based Evaluation of Older People's Fall Risk Using the mHealth App Lindera Mobility Analysis: Exploratory Study

Background

Falls and the risk of falling in older people pose a high risk for losing independence. As the risk of falling progresses over time, it is often not adequately diagnosed due to the long intervals between contacts with health care professionals. This leads to the risk of falling being not properly detected until the first fall. App-based software able to screen fall risks of older adults and to monitor the progress and presence of fall risk factors could detect a developing fall risk at an early stage prior to the first fall. As smartphones become more common in the elderly population, this approach is easily available and feasible.

Objective

The aim of the study is to evaluate the app Lindera Mobility Analysis (LIN). The reference standards determined the risk of falling and validated functional assessments of mobility.

Methods

The LIN app was utilized in home- and community-dwelling older adults aged 65 years or more. The Berg Balance Scale (BBS), the Tinetti Test (TIN), and the Timed Up & Go Test (TUG) were used as reference standards. In addition to descriptive statistics, data correlation and the comparison of the mean difference of analog measures (reference standards) and digital measures were tested. Spearman rank correlation analysis was performed and Bland-Altman (B-A) plots drawn.

Results

Data of 42 participants could be obtained (n=25, 59.5%, women). There was a significant correlation between the LIN app and the BBS (r=–0.587, P<.001), TUG (r=0.474, P=.002), and TIN (r=–0.464, P=.002). B-A plots showed only few data points outside the predefined limits of agreement (LOA) when combining functional tests and results of LIN.

Conclusions

The digital app LIN has the potential to detect the risk of falling in older people. Further steps in establishing the validity of the LIN app should include its clinical applicability.

Gait Biomechanics for Fall Prevention among Older Adults

In our currently ageing society, fall prevention is important for better healthy life expectancy and sustainable healthcare systems. While active outdoor walking is recommended as adequate exercise for the senior population, falls due to tripping and slipping exist as the primary causes of severe injuries. Minimum foot clearance (MFC) is the lowest vertical height of the foot during the mid-swing phase and indicates the risk of tripping. In contrast, coefficient of friction (COF) factors determine the occurrence of falls from slipping. Optimisation of the MFC and the COF for every step cycle prevents tripping and slipping, respectively. Even after the initiation of hazardous balance loss (i.e., tripping and slipping), falls can still be prevented as long as the requirements for balance are restored. Biomechanically, dynamic balance is defined by the bodily centre of mass and by the base of support: spatially—margin of stability and temporally—available response time. Fall prevention strategies should, therefore, target controlling the MFC, the COF and dynamic balance. Practical intervention strategies include footwear modification (i.e., shoe-insole geometry and slip-resistant outsoles), exercise (i.e., ankle dorsiflexors and core stabilisers) and technological rehabilitation (i.e., electrical stimulators and active exoskeletons). Biomechanical concepts can be practically applied to various everyday settings for fall prevention among the older population.

Predictors of fall-related injuries due to common consumer products among elderly adult emergency department visits in the United States during 2007-2017

Falls are the leading cause of injuries and death among the elderly in the United States (U.S.). This study examined unintentional fall related-injuries and potential associations between various consumer products. Data was analyzed from the National Electronic Injury Surveillance System (NEISS) of hospital emergency department (ED) visits for unintentional injuries among the elderly between 2007 and 2017. Multiple logistic regression was used to examine the association between consumer products and fall-related injury ED visits. A total of 537,703 injury-related ED visits were analyzed. Two-thirds of visits were fall-related. Of those, 33% were among those 85 years and older, 62.5% occurred at home, 37.6% had head trauma, and 28.7% resulted in hospitalization. Flooring materials accounted for 29.1% of injuries. Ladders were significantly associated with fall-related injuries (adjusted odds ratio [AOR] 5.48, 95% confidence interval [CI] 4.72-6.36), followed by flooring materials (AOR 3.09, 95% CI 2.60-3.67), and porches and balconies (AOR 2.61, 95% CI 2.30-2.96). Several common consumer products are associated with fall-related injuries among the elderly. Increased awareness and education are critical.

Cost-Benefit Analysis of the COPE Program for Persons Living With Dementia: Toward a Payment Model

BACKGROUND AND OBJECTIVES

There is a critical need for effective interventions to support quality of life for persons living with dementia and their caregivers. Growing evidence supports nonpharmacologic programs that provide care management, disease education, skills training, and support. This cost-benefit analysis examined whether the Care of Persons with Dementia in their Environments (COPE) program achieves cost savings when incorporated into Connecticut's home- and community-based services (HCBS), which are state- and Medicaid-funded.

RESEARCH DESIGN AND METHODS

Findings are based on a pragmatic trial where persons living with dementia and their caregiver dyads were randomly assigned to COPE with HCBS, or HCBS alone. Cost measures included those relevant to HCBS decision makers: intervention delivery, health care utilization, caregiver time, formal care, and social services. Data sources included care management records and caregiver report.

RESULTS

Per-dyad mean cost savings at 12 months were $2 354 for those who received COPE with a mean difference-in-difference of -$6 667 versus HCBS alone (95% CI: -$15 473, $2 734; not statistically significant). COPE costs would consume 5.6%-11.3% of Connecticut's HCBS annual spending limit, and HCBS cost-sharing requirements align with participants' willingness to pay for COPE.

DISCUSSION AND IMPLICATIONS

COPE represents a potentially cost-saving dementia care service that could be financed through existing Connecticut HCBS. HCBS programs represent an important, sustainable payment model for delivering nonpharmacological dementia interventions such as COPE.

Organizational Capacity Building in Nursing Facilities to Promote Resident Mobility: A Systematic Review

OBJECTIVES

The objective of the present systematic review was to investigate the effects of organizational capacity building interventions on the environment, nursing staff capacity, and mobility of residents in nursing facilities.

DESIGN

Systematic review.

SETTING AND PARTICIPANTS

Nursing facilities, staff, and residents.

METHODS

We conducted a systematic review according to the methods of the Cochrane Collaboration. The systematic review was prospectively registered in the PROSPERO database of systematic reviews (registration number CRD42020202996). We searched for studies in MEDLINE (via PubMed), CINAHL (via EBSCO), the Physiotherapy Evidence Database (PEDro), and the Cochrane Library (07/20). A narrative synthesis was conducted because of the high heterogeneity of the included studies.

RESULTS

We identified 6747 records and included 14 studies in our review. We clustered the 14 interventions into 3 different categories (environmental modification, nursing staff capacity, and multifactorial interventions). Three studies assessed outcomes at the nursing staff level, and all studies reported outcomes at the resident level. We found highly heterogeneous and inconsistent effects of organizational capacity building on increasing nursing staff capacity and/or resident mobility.

CONCLUSIONS AND IMPLICATIONS

The findings emphasize the need for further research focusing on an international understanding and definition of organizational capacity building. Additionally, research and intervention development for organizational capacity building interventions to promote resident mobility are needed while applying the framework of the Medical Research Council. Furthermore, studies should assess outcomes regarding the environment and nursing staff to better understand if and how environmental structures and nursing staff capacity effect resident mobility.

Factors Related to Self-Confidence to Live Alone in Community-Dwelling Older Adults: A Cross-Sectional Study

BACKGROUND

Many older adults prefer to live alone in their own homes, with age-related issues in physical movement, regardless of their cultural background. Importantly, however, to identify the features of successfully ageing in place (AIP), and foster independent living among these individuals, this study explored their level of self-confidence to live alone and its related factors.

METHODS

We conducted a cross-sectional study using secondary data from an earlier study with older adults living alone in South Korea recruited by convenience sampling methods (N = 936, mean age = 77.1 years, 76.1% female). Data regarding the general, health-related, and social characteristics as well as self-confidence to live alone were collected via face-to-face interviews in 2019. Self-confidence to live alone was measured with a numeric rating scale of 0 to 10.

RESULTS

The average self-confidence score to live alone was 6.59. A regression analysis showed that mould exposure at home, depression, emergency department visits, and loneliness hinder self-confidence to live alone. Meanwhile, such self-confidence was facilitated by independency in instrumental activities of daily living (IADL), interactions with family members, social service utilisation, and social support.

CONCLUSIONS

This study suggests that healthcare providers need to consider the importance of self-confidence to live alone and influencing functional, mental, social, and environmental factors to promote quality of life as well as successful AIP for older adults living alone. Further, self-confidence to live alone could be a new practical index in the field of health and ageing to screen the successful AIP of older adults living alone.

Stabilometric analysis as a cognitive function predictor in adults over the age of 50: A cross-sectional study conducted in a Memory Clinic

BACKGROUND

The aging process reduces adaptive balance responses. Two-thirds of older adults with cognitive problems suffer at least one fall every year, a rate three times higher than that observed in older adults without dementia. This cross-sectional study aims to analyze the relationship between balance and cognitive status in adults older than 50 years.

METHODS

Individuals over the age of 50, who attended a Memory Clinic, were evaluated for balance changes using stabilometry, with analysis of the center of pressure (CoP). The following CoP parameters were assessed using an S-Plate pressure platform: 1) sway length, 2) sway area, and 3) anteroposterior and laterolateral sway (width, mean deviation, and speed). The individuals were evaluated with eyes open and closed for 30 s in each test. The Montreal Cognitive Assessment (MoCA) was used to assess cognitive status.

RESULTS

Eighty-seven subjects participated in the study. The average age was 67.8 years, 81.4% were female, and the average MoCA score was 19.8 points. Greater CoP oscillation was observed in the eyes closed condition, demonstrating greater postural imbalance. We found a significant and direct effect of MoCA score on the CoP area in the eyes open condition.

CONCLUSION

The results suggest that stabilometric analysis may be a predictor of cognitive function.

Risk Factors for Intracranial Injury Caused by Falls at Home in Korea Using Data from the Emergency Department-based Injury In-depth Surveillance (2011-2018)

BACKGROUND

Most unintentional injuries that occur at home are preventable. However, it may be difficult to sufficiently reduce the number of falls occurring at home by only identifying risk factors focused on specific age groups. Therefore, this study aimed to identify the risk factors (especially age and places where injuries occurred at home) for intracranial injury (ICI) caused by unintentional falls at home.

METHODS

Using the Emergency Department (ED)-Based Injury In-depth Surveillance, we analyzed the data of patients who visited the ED due to unintentional falls at home. Risk factors were identified using multivariable logistic regression according to age groups and interactions between place of injury occurrence and age groups, and sex and age groups were assessed.

RESULTS

In total, 232,124 patients were included in the analysis; older adults had a higher adjusted odds ratio (aOR) 14.05 (95% confidence interval [CI], 12.74-15.49) of ICI than infants. The corridor was associated with ICI in the male pediatric group (aOR, 2.71; 95% CI, 1.08-6.84) and the balcony with the female pediatric group (aOR, 2.04; 95% CI, 1.03-4.04). In the adult group, aOR of kitchen was 1.38 (95% CI, 1.02-1.88) in females and 0.56 (95% CI, 0.48-0.66) in males.

CONCLUSION

In this study, we identified the risk factors of ICI caused by falls at home using ED-based injury surveillance data. The risk of ICI was different among places of occurrence in the home depending on the age groups and sex.

Technology Utilization in Fall Prevention

ABSTRACT

Falls, defined as unplanned descents to the floor with or without injury to an individual, remain to be one of the most challenging health conditions. Fall rate is a key quality metric of acute care hospitals, rehabilitation settings, and long-term care facilities. Fall prevention policies with proper implementation have been the focus of surveys by regulatory bodies, including The Joint Commission and the Centers for Medicare and Medicaid Services, for all healthcare settings. Since October 2008, the Centers for Medicare and Medicaid Services has stopped reimbursing hospitals for the costs related to patient falls, shifting the accountability for fall prevention to the healthcare providers. Research shows that almost one-third of falls can be prevented and extensive fall prevention interventions exist. Recently, technology-based applications have been introduced in healthcare to obtain superior patient care outcomes and experience via efficiency, access, and reliability. Several areas in fall prevention deploy technology, including predictive and prescriptive analytics using big data, video monitoring and alarm technology, wearable sensors, exergame and virtual reality, robotics in home environment assessment, and personal coaching. This review discusses an overview of these technology-based applications in various settings, focusing on the outcomes of fall reductions, cost, and other benefits.

Exercise Effects on Falls, Fractures, Hospitalizations, and Mortality in Older Adults With Dementia: An Individual-Level Patient Data Meta-analysis

Background

To study the effects of exercise on falls, fractures, hospitalizations, and death in people with dementia.

Method

We conducted an individual-level patient data meta-analysis of 7 randomized controlled trials (RCTs). We looked for studies from the reference list of previous systematic reviews and undertook an electronic search for articles published between 2013 and 2019 in Ageline, CENTRAL, PsycINFO, PubMed, and SportsDiscus. Main (binary) outcome measures were the risk of mortality, hospitalization, faller, multiple faller, injurious faller, and fractures. Secondary (count) outcomes were the incident rates of hospitalizations, falls, and injurious falls.

Results

From the 1314 participants, 771 were allocated to the exercise group and 543 to the control group. The number of cases regarding the main outcome measures in exercisers and controls were, respectively: 45 (5.8%) and 31 (5.7%) deaths; 102 (14.4%) and 65 (13.4%) participants hospitalized; 221 (34.4%) and 175 (41.3%) had at least 1 fall; 128 (20.2%) and 92 (21.7%) had multiple falls; 78 (24.8%) and 92 (29.3%) had injurious falls; and 19 (2.9%) and 15 (3.5%) had suffered a fracture. Two-step meta-analysis found no effects of exercise on any outcome. One-step meta-analysis found exercise reduced the risk of falls (odds ratio 0.75; 95% CI: 0.57–0.99). Exploratory analysis showed exercise decreased the rate of incident falls in participants with the lowest functional ability (incident rate ratio 0.48; 95% CI: 0.30–0.79).

Conclusions

Although the 2-step meta-analysis suggests exercise does not have an effect on the outcomes, 1-step meta-analysis suggested that exercise may reduce fall risk. Data from further high-quality RCTs are still needed.

Associations between living alone, depression, and falls among community-dwelling older adults in the US

Social isolation is closely linked to depression and falls in late life and are common among seniors. Although the literature has highlighted age-related variations in these three geriatric conditions, evidence on heterogeneities across older adult age categories is lacking. To address this gap, we present cross-sectional analyses using indicators of social isolation, depression, and falls of older adults constructed from the most recent Behavioral Risk Factor Surveillance System (BRFSS) data. An age-based understanding is critical to improve health interventions since health changes occur at a faster rate among seniors than in any other population subgroup. We included all adults 60 years and older (n = 113,233) in the 2018 BRFSS landline dataset and used the status of living alone, depressive disorder diagnosis, and fall incidences reported by these seniors to respectively create the social isolation, depression, and fall indicators. We conducted multivariable logistic regressions to compare findings on these indicators across the three age categories of 60-69, 70-79, and 80 and above after adjusting for a common set of covariates. Results indicate that the likelihood of seniors living alone and reporting depression is the highest among those 80 years and above. Conversely, the odds of depressed seniors reporting falls is the greatest among the 60-69 year olds. Accordingly, we highlight key implications for targeted health promotion and care delivery to seniors.

A Randomized Trial of a Multifactorial Strategy to Prevent Serious Fall Injuries

BACKGROUND

Injuries from falls are major contributors to complications and death in older adults. Despite evidence from efficacy trials that many falls can be prevented, rates of falls resulting in injury have not declined.

METHODS

We conducted a pragmatic, cluster-randomized trial to evaluate the effectiveness of a multifactorial intervention that included risk assessment and individualized plans, administered by specially trained nurses, to prevent fall injuries. A total of 86 primary care practices across 10 health care systems were randomly assigned to the intervention or to enhanced usual care (the control) (43 practices each). The participants were community-dwelling adults, 70 years of age or older, who were at increased risk for fall injuries. The primary outcome, assessed in a time-to-event analysis, was the first serious fall injury, adjudicated with the use of participant report, electronic health records, and claims data. We hypothesized that the event rate would be lower by 20% in the intervention group than in the control group.

RESULTS

The demographic and baseline characteristics of the participants were similar in the intervention group (2802 participants) and the control group (2649 participants); the mean age was 80 years, and 62.0% of the participants were women. The rate of a first adjudicated serious fall injury did not differ significantly between the groups, as assessed in a time-to-first-event analysis (events per 100 person-years of follow-up, 4.9 in the intervention group and 5.3 in the control group; hazard ratio, 0.92; 95% confidence interval [CI], 0.80 to 1.06; P = 0.25). The rate of a first participant-reported fall injury was 25.6 events per 100 person-years of follow-up in the intervention group and 28.6 events per 100 person-years of follow-up in the control group (hazard ratio, 0.90; 95% CI, 0.83 to 0.99; P = 0.004). The rates of hospitalization or death were similar in the two groups.

CONCLUSIONS

A multifactorial intervention, administered by nurses, did not result in a significantly lower rate of a first adjudicated serious fall injury than enhanced usual care. (Funded by the Patient-Centered Outcomes Research Institute and others; STRIDE ClinicalTrials.gov number, NCT02475850.).
