Effectiveness of dance interventions for falls prevention in older adults: systematic review and meta-analysis

INTRODUCTION

Fall prevention is a global health priority. Strength and balance exercise programmes are effective at reducing falls. Emerging literature suggests dance is an enjoyable and sociable form of exercise. However, there is little evidence that dance reduces fall incidence.

METHODS

Systematic review and meta-analysis examining effectiveness and cost-effectiveness of dance for falls prevention in older adults. Five databases were searched with no restrictions on publication date or intervention settings. Risk of bias was assessed using variants of Cochrane Risk of bias tools, Mixed-Methods Appraisal and Drummond checklist as appropriate. Certainty of evidence was assessed using GRADE.

RESULTS

Forty-one studies were included (19 RCTs, 13 quasi-experimental, two mixed-method, seven observational studies, 2,451 participants). Five types of dance interventions were identified: ballroom and Latin dance, dance exercise, cultural dance, dance therapy, and low-impact dance. Meta-analysis was only possible for functional outcome measures: Timed-Up-and-Go (dance versus usual care, mean difference (MD) = 1.36; 95% CI -3.57 to 0.85), Sit-to-Stand (dance versus exercise MD = -0.85; 95% CI -2.64 to 0.93: dance versus education MD = -1.64; 95% CI -4.12 to 0.85), Berg Balance Scale (dance versus usual care MD = 0.61; 95% CI -4.26 to 5.47). There was unexplained variance in effects and no significant differences between intervention and control groups. Overall, certainty of evidence was very low; we are uncertain about the effect of dance interventions in reducing falls.

CONCLUSIONS

There is very low certainty evidence for dance as an alternative to strength and balance training if the aim is to prevent falls. No robust evidence on the cost-effectiveness of dance interventions for the prevention of falls was found.

Relationship between staff and quality of care in care homes: StaRQ mixed methods study

Background

Quality of life and care varies between and within the care homes in which almost half a million older people live and over half a million direct care staff (registered nurses and care assistants) work. The reasons are complex, understudied and sometimes oversimplified, but staff and their work are a significant influence.

Objective(s)

To explore variations in the care home nursing and support workforce; how resident and relatives' needs in care homes are linked to care home staffing; how different staffing models impact on care quality, outcomes and costs; how workforce numbers, skill mix and stability meet residents' needs; the contributions of the care home workforce to enhancing quality of care; staff relationships as a platform for implementation by providers.

Design

Mixed-method (QUAL-QUANT) parallel design with five work packages. WP1 - two evidence syntheses (one realist); WP2 - cross-sectional survey of routine staffing and rated quality from care home regulator; WP3 - analysis of longitudinal data from a corporate provider of staffing characteristics and quality indicators, including safety; WP4 - secondary analysis of care home regulator reports; WP5 - social network analysis of networks likely to influence quality innovation. We expressed our synthesised findings as a logic model.

Setting

English care homes, with and without nursing, with various ownership structures, size and location, with varying quality ratings.

Participants

Managers, residents, families and care home staff.

Findings

Staffing's contribution to quality and personalised care requires: managerial and staff stability and consistency; sufficient staff to develop 'familial' relationships between staff and residents, and staff-staff reciprocity, 'knowing' residents, and skills and competence training beyond induction; supported, well-led staff seeing modelled behaviours from supervisors; autonomy to act. Outcome measures that capture the relationship between staffing and quality include: the extent to which resident needs and preferences are met and culturally appropriate; resident and family satisfaction; extent of residents living with purpose; safe care (including clinical outcomes); staff well-being and job satisfaction were important, but underacknowledged.

Limitations

Many of our findings stem from self-reported and routine data with known biases - such as under reporting of adverse incidents; our analysis may reflect these biases. COVID-19 required adapting our original protocol to make it feasible. Consequently, the effects of the pandemic are reflected in our research methods and findings. Our findings are based on data from a single care home operator and so may not be generalised to the wider population of care homes.

Conclusions

Innovative and multiple methods and theory can successfully highlight the nuanced relationship between staffing and quality in care homes. Modifiable characteristics such as visible philosophies of care and high-quality training, reinforced by behavioural and relational role modelling by leaders can make the difference when sufficient amounts of consistent staff are employed. Greater staffing capacity alone is unlikely to enhance quality in a cost-effective manner. Social network analysis can help identify the right people to aid adoption and spread of quality and innovation. Future research should focus on richer, iterative, evaluative testing and development of our logic model using theoretically and empirically defensible - rather than available - inputs and outcomes.

The prehospital management of ambulance-attended adults who fell: A scoping review

BACKGROUND

The ageing population is requiring more ambulance attendances for falls. This scoping review aimed to map and synthesise the evidence for the prehospital management of Emergency Medical Services (EMS) attended adult patients who fall.

METHODS

The Joanna Briggs Institute methods for scoping reviews were used. Six databases were searched (Medline, Scopus, CINAHL, Cochrane, EMBASE, ProQuest), 1st August 2021. Included sources reported: ambulance attended (context), adults who fell (population), injuries, interventions or disposition data (concept). Data were narratively synthesised.

RESULTS

One-hundred and fifteen research sources met the inclusion criteria. Detailed information describing prehospital delivered EMS interventions, transport decisions and alternative care pathways was limited. Overall, adults< 65 years were less likely than older adults to be attended repeatedly and/or not transported. Being male, falling from height and sustaining severe injuries were associated with transport to major trauma centres. Older females, falling from standing/low height with minor injuries were less likely to be transported to major trauma centres.

CONCLUSION

The relationship between patient characteristics, falls and resulting injuries were well described in the literature. Other evidence about EMS management in prehospital settings was limited. Further research regarding prehospital interventions, transport decisions and alternative care pathways in the prehospital setting is recommended.

Trajectories of mobility difficulty and falls in community-dwelling adults aged 50 + in Taiwan from 2003 to 2015

BACKGROUND

A decline in mobility leads to fall occurrence and poorer performance in instrumental activities of daily living, which are widely proved to be associated with older adults' health-related quality of life. To inform potential predicaments faced by older adults at different age levels, predictors of this mobility change and falls along with the ageing process need to be further evaluated. Therefore, this study examined the risk factors associated with the longitudinal course of mobility difficulty and falls among community-dwelling middle-aged and older adults in the Taiwanese community.

METHODS

We evaluated data for the period between 2003 and 2015 from the Taiwan Longitudinal Study on Aging; the data cover 5267 community-based middle-aged and older adults with approximately 12 years of follow-up. In terms of mobility, the participants self-reported difficulties in mobility tasks (eg, ambulation) and whether they used a walking device. We employed linear mixed-effects regression models and cumulative logit models to examine whether personal characteristics are associated with mobility difficulty and falls.

RESULTS

Mobility difficulty significantly increased over time for the participants aged ≥ 60 years. Perceived difficulties in standing, walking, squatting, and running became apparent from a younger age than limitations with hand function. The probability of repeated falls increased significantly with older age at 70 (p = .002), higher level of mobility difficulty (p < .0001), lower cognitive status (p = .001), living alone (p = .001), higher number of comorbid illnesses (p < .001), walking device use (p = .003), longer time in physical activities (p < .011), and elevated depressive symptoms (p = .006). Although walking aid use increased the probability of falls, individuals with mobility difficulty had a reduced probability of repeated falls when using a walking device (p = .02).

CONCLUSION

Community-dwelling Taiwanese adults face an earlier mobility difficulty starting in 60 years old. Individuals with more leisure and physical activities in daily life were more likely to maintain mobility and walking safety. Long-term, regular, social, and physical activity could be a referral option for falls prevention program. The use of a walking device and safety precautions are warranted, particularly for individuals with walking difficulties.

Knowledge about foot-specific foot falls risk factors and exercise among physiotherapists in the UK and Portugal: A cross-sectional survey

Background and purpose

Foot‐related falls risk factors and specific foot and ankle exercise interventions are within the scope of Physiotherapy, yet little is known about United Kingdom (UK) and Portugal‐based (PT) physiotherapists' self‐perceived knowledge, confidence and practice of such interventions, or perceptions of patients' falls prevention knowledge. The purpose of this study was to assess levels of self‐reported knowledge, confidence, and practices surrounding foot‐specific falls risk and exercise for fall prevention in physiotherapists working in the UK and in Portugal. It also aimed to explore physiotherapists' views about their participants' falls prevention knowledge.

Methods

A self‐report online survey was developed, and pilot tested in both nations. Registered Physiotherapists were invited to participate through their professional associations, social media and snowballing. Mann‐Whitney tests were used to compare mean ranks of ordinal variables between nations and Chi‐square test to assess the independency between pairs of variables. Spearman's correlation coefficient (rs) was used to measure the association between pairs of variables (p < 0.05).

Results

682 physiotherapists participated in the survey [UK n = 229 (mean (SD) age = 43(10) years, 86.9% female]; PT n = 453 (mean (SD) age = 33(9) years, 78.3% female]. Among physiotherapists with a caseload of ≥70% older adults, more PT‐based physiotherapists held postgraduate qualifications (p = 0.01). Most physiotherapists correctly identified generic and foot‐specific risk factors (≥70% of participants for each item). More UK‐based physiotherapists reported always prescribing ankle and foot exercises (42.6% vs. 33%, p =< 0.001) and displayed higher levels of self‐reported confidence surrounding exercise‐based interventions.

Discussion

Our sample of UK and Portugal‐based physiotherapists are aware of the contribution of foot‐specific risk factors and exercise to falls prevention, with the former group being more confident in exercise‐based interventions. Both groups of physiotherapists perceived that their older patients had little knowledge about these topics, with UK older adults having slightly better knowledge on generic falls risk factors at first contact. Future studies and strategies for knowledge translation and education in foot health and foot function screening and management for physiotherapists, within a falls prevention scope, may be informed by this study.

Risk factors for falls among older adults in India: A systematic review and meta‐analysis

Background and Aim

Falls are common among older adults in India. Several primary studies on its risk factors have been conducted in India. However, no systematic review has been conducted on this topic. Thus, the objective of this systematic review was to synthesize the existing evidence on the risk factors for falls among older adults in India.

Methods

JBI and Preferred Reporting Items for Systematic Reviews and Meta‐Analyse guidelines were followed, and two independent reviewers were involved in the process. This review included observational studies conducted among older adults (aged ≥ 60 years) residing in India, reporting any risk factor for falls as exposure and unintentional fall as the outcome. MEDLINE, EMBASE, PsycInfo, CINAHL, and ProQuest Dissertations and Theses were searched until September 24, 2020. Where possible, data were synthesized using random‐effects meta‐analysis.

Results

The literature search yielded 3445 records. Twenty‐two studies met the inclusion criteria of this systematic review, and 19 studies were included in the meta‐analysis. Out of the 22 included studies in the systematic review, 12 (out of 18) cross‐sectional studies, two case–control studies, and two cohort studies met more than 70% criteria in the respective Joanna Briggs Institute (JBI) checklists. Risk factors for falls among older adults in India included sociodemographic factors, environmental factors, lifestyle factors, physical and/or mental health conditions, and medical interventions.

Conclusions

This systematic review and meta‐analysis provided a holistic picture of the problem in India by considering a range of risk factors such as sociodemographic, environmental, lifestyle, physical and/or mental health conditions and medical intervention. These findings could be used to develop falls prevention interventions for older adults in India.

Hospitalization of unintentional fall injuries in Kuwait: a national database study

BACKGROUND

Accidental falls are a major cause of morbidity placing pressure on hospital capacity and utilizing costly services. Evaluating the burden of falls is key for planning, implementation, and evaluation of prevention strategies. To date, no studies have been published on accidental falls at the population level in Kuwait. We studied the burden of accidental falls on public hospital inpatient capacity in Kuwait and identified the subgroups with the highest utilization of inpatient service days.

METHODS

From the national database of inpatient hospitalizations, we selected hospitalizations of patients admitted to Kuwait's public hospitals for unintentional injury caused by an accidental fall from 1 January through 31 December 2016. We studied the number of inpatient service days (bed days), length of stay (LOS), and number of hospitalizations by age group, gender, and nationality. Mann-Whitney, Kruskal-Wallis, and Chi square tests were used for comparison. Logistic regression was used to quantify the risk of prolonged LOS and fractures among fall-related hospitalizations.

RESULTS

Accidental falls were responsible for 2.9% of inpatient hospitalizations, 3.7% of inpatient service days (61,140 days) with an ALOS of 9.1 days in Kuwait's public hospitals in 2016. Accidental falls were responsible for 4.6% of older adult service days, and an even higher 5.6% of older women service days. In the age group 13-64, fall-related service days for non-Kuwaitis (5.7%) were more than triple those for Kuwaitis (1.8%) with a substantial percentage among male non-Kuwaitis (8.1%). The risk factors for exceeding the national ALOS for fall-related hospitalizations were female gender (OR 1.36), age 65 and older (OR 9.72), age 13-64 (OR 5.20), being non-Kuwaiti (OR 1.39), sustaining a femur fracture (OR 11.67), and undergoing surgery (OR 2.63). Fall-related hospitalizations associated with a higher risk of fractures were females (OR 1.22), patients 65 years and older (OR 5.09), patients aged 13-64 (OR 3.65), and non-Kuwaitis (OR 1.28).

CONCLUSIONS

Accidental falls impose a considerable burden on inpatient service utilization in Kuwait. This varies by age, gender, and nationality. To reduce this burden, prevention programs should target working-age non-Kuwaiti males and older females.

Cardiovascular Disorders Mediated by Autonomic Nervous System Dysfunction

Cardiovascular disorders, such as orthostatic hypotension and supine hypertension, are common in patients with neurodegenerative synucleinopathies such as Parkinson disease (PD), and may also occur in other conditions, such as peripheral neuropathies, that result in autonomic nervous system (ANS) dysfunction. Dysfunction and degeneration of the ANS are implicated in the development of orthostatic and postprandial hypotension and impaired thermoregulation. Neurogenic orthostatic hypotension (nOH) results from sympathetic failure and is a common autonomic disorder in PD. Supine hypertension may also occur as a result of both sympathetic and parasympathetic dysfunction in conjunction with nOH in the majority of patients with PD. Management of supine hypertension in the setting of nOH can be counterintuitive and challenging. Additionally, the presence of other noncardiovascular comorbidities, such as diabetes mellitus and peripheral edema, may further contribute to the burden of disease. ANS dysfunction thus presents major healthcare implications and challenges for neurology and cardiovascular practices, necessitating an integrated neurology and cardiology management approach.

Effect of Senior Dance (DanSE) on Fall Risk Factors in Older Adults: A Randomized Controlled Trial

BACKGROUND

Older people's participation in structured exercise programs to improve balance and mobility is low. Senior Dance is an alternative option, as it may provide a safe and fun way of targeting balance.

OBJECTIVE

The aim was to investigate the effect of Senior Dance on balance, mobility, and cognitive function compared with a control intervention.

DESIGN

The study was a randomized controlled trial.

SETTING/PATIENTS

Eighty-two community-dwelling older people aged 60 years or over and cognitively intact were recruited in Brazil.

INTERVENTION

Participants were randomly allocated to 2 groups: Dance plus education (intervention group) and education alone (control group). The Senior Dance program consisted of 12 weeks of twice-weekly group-based dance classes. Participants in both groups attended a single 1-hour educational session on prevention of falls.

MEASUREMENTS

The primary outcome was single-leg stance with eyes closed. Secondary outcomes were timed sit-to-stand test, standing balance test, timed 4-m walk, and cognitive function tests, for example, Trail Making Test and Montreal Cognitive Assessment.

RESULTS

Of the 82 participants randomized, 71 (87%) completed the 12-week follow-up. Single-leg stance with eyes closed (primary outcome) improved in the Senior Dance group (mean difference [MD] = 2.3 seconds, 95% confidence interval [CI] = 1.1 to 3.6) compared with the control group at follow-up. Senior Dance group performed better in the standing balance tests (MD = 3.7 seconds, 95% CI = 0.6 to 6.8) and were faster in the sit-to-stand test (MD = - 3.1 seconds, 95% CI = -4.8 to -1.4) and 4-m walk test (MD = -0.6 seconds, 95% CI = -1.0 to -0.1). There were no significant between-group differences for cognitive function tests.

LIMITATIONS

Participants and therapists were not blinded.

CONCLUSION

Senior Dance was effective in improving balance and mobility but not cognitive function in community-dwelling older people.

Health-Related Problems and Drivers of Health-Related Quality of Life Among Community-Dwelling Older Adults

Purpose: The aims of this study were to explore prevalence of health-related problems and identify factors associated with health-related quality of life (HRQOL) among community-dwelling older adults (CDOAs) in rural Thailand. Methods: A total of 384 CDOAs with mean age of 71 years (SD = 7.6) were recruited. The Thai Ministry of Public Health’s comprehensive geriatric assessment (CGA) was used to measure the CDOAs’ health conditions in the primary care unit of community hospitals. HRQOL of the participants was assessed by using the EQ-5D questionnaire. Results: The results showed that the most common health-related problems were risk of glaucoma (89.6%) and hypertension (64.6%). The HRQOL were predicted by the incidence of falls (β = −0.076, P < .001), Timed Up and Go Test (β = −0.087, P < .001), and age (β = −0.667, P = .002). Discussion: This study highlighted the need to incorporate CGA in family practice, which included risk of falls assessment by measuring TUG test, fall prevention, and to provide resources for caring older adults at home which ultimately will improve CDOAs’ quality of life.

Using supervised learning machine algorithm to identify future fallers based on gait patterns: A two-year longitudinal study

INTRODUCTION

Given their major health consequences in the elderly, identifying people at risk of fall is a major challenge faced by clinicians. A lot of studies have confirmed the relationships between gait parameters and falls incidence. However, accurate tools to predict individual risk among independent older adults without a history of falls are lacking.

OBJECTIVE

This study aimed to apply a supervised learning algorithm to a data set recorded in a two-year longitudinal study, in order to build a classification tree that could discern subsequent fallers based on their gait patterns.

METHODS

A total of 105 adults aged >65 years, living independently at home and without a recent fall history were included in a two-year longitudinal study. All underwent physical and functional assessment. Gait speed, stride length, frequency, symmetry and regularity, and minimum toe clearance were recorded in comfortable, fast and dual task walking conditions in a standardized laboratory environment. Fall events were recorded using personal falls diaries. A supervised machine learning algorithm (J48) has been applied to the data recorded at inclusion in order to obtain a classification tree able to identify future fallers.

RESULTS

Based on fall information from 96 volunteers, a classification tree correctly identifying 80% of future fallers based on gait patterns, gender, and stiffness, was obtained, with accuracy of 84%, sensitivity of 80%, specificity of 87%, a positive predictive value of 78%, and a negative predictive value of 88%.

DISCUSSION

While the performances of the classification tree warrant further confirmation, it is the first predictive tool based on gait parameters that are identified (not clustered) allowing its use by other research teams.

CONCLUSION

This original longitudinal pilot study using a supervised machine learning algorithm, shows that gait parameters and clinical data can be used to identify future fallers among independent older adults.

Gait symmetry in the dual task condition as a predictor of future falls among independent older adults: a 2-year longitudinal study

BACKGROUND

Given the potential consequences of falls among older adults, a major challenge is to identify people at risk before the first event. In this context, gait parameters have been suggested as markers of fall risk.

AIM

To examine, among older people, the prospective relationship between gait patterns assessed in comfortable and challenging walking conditions, and future fall(s).

METHOD

A total of 105 adults older than 65 years, living independently at home and without a recent fall history were included in a 2-year, longitudinal, observational study. All underwent physical and functional assessment. Gait speed, stride length, frequency, symmetry and regularity and Minimum Toe Clearance (MTC) were recorded in comfortable (CW), fast (FW) and dual task walking (DTW) conditions. Gait parameter changes occurring between CW and FW and between CW and DTW were calculated and expressed in percent. DTW cost was calculated as the change of DTW relative to CW. Fall events were recorded using fall diaries. Comparisons according to fall occurrence were performed by means of univariate analysis and multivariate binary logistic regression analysis.

RESULTS

Two-year follow-up was available for 96 participants, of whom 35 (36.5%) fell at least once. Comparative analysis showed that future fallers had shorter FW stride length and higher symmetry DTW cost than non-fallers (p < 0.05). Binary logistic regression analysis showed that each additional percent of stride symmetry cost was associated with an increase in future fall risk (odds ratio 1.018, 95% Confidence Interval (CI) 1.002-1.033; p = 0.027).

DISCUSSION

Our results confirm the association between a symmetry decrease in DTW and future fall(s). Indeed in this study, the mean symmetry DTW cost in fallers is almost 20% higher than in non-fallers, meaning a fall risk that is around 36% higher than among non-fallers.

CONCLUSION

This exploratory study shows the usefulness of considering gait parameters, particularly symmetry in challenging walking conditions, for early identification of future fallers.

Enabling older adults to carry out paperless falls-risk self-assessments using guidetomeasure-3D: A mixed methods study

BACKGROUND

The home environment falls-risk assessment process (HEFAP) is a widely used falls prevention intervention strategy which involves a clinician using paper-based measurement guidance to ensure that appropriate information and measurements are taken and recorded accurately. Despite the current use of paper-based guidance, over 30% of all assistive devices installed within the home are abandoned by patients. This is in part due to poor fit between the device, the patient, and the environment in which it is installed. Currently HEFAP is a clinician-led process, however, older adult patients are increasingly being expected to collect HEFAP measurements themselves as part of the personalisation agenda. Without appropriate patient-centred guidance, levels of device abandonment to are likely to rise to unprecedented levels. This study presents guidetomeasure-3D, a mobile 3D measurement guidance application designed to support patients in carrying out HEFAP self-assessments.

AIM

The aim of this study is to present guidetomeasure-3D, a web-enabled 3D mobile application that enables older-adult patients to carry out self-assessment measurement tasks, and to carry out a mixed-methods evaluation of its performance, and associated user perceptions of the application, compared with a 2D paper-based equivalent.

METHODS

Thirty-four older adult participants took part in a mixed-methods within-subjects repeated measures study set within a living lab. A series of HEFAP self-assessment tasks were carried out according to two treatment conditions: (1) using the 3D guidetomeasure-3D application; (2) using a 2D paper-based guide. SUS questionnaires and semi-structured interviews were completed at the end of the task. A comparative statistical analysis explored performance with regards to measurement accuracy, accuracy consistency, task efficiency, and system usability. Interview transcripts were analysed using inductive and deductive thematic analysis (informed by UTAUT).

RESULTS

The guidetomeasure-3D application outperformed the 2D paper-based guidance in terms of accuracy (smaller mean error difference in 11 out of 12 items), accuracy consistency (p < 0.05, for 6 out of 12 items), task efficiency (p = 0.003), system usability (p < 0.00625, for two out of 10 SUS items), and clarity of guidance (p < 0.0125, for three out of four items). Three high-level themes emerged from interviews: Performance Expectancy, Effort Expectancy, and Social Influence. Participants reported that guidetomeasure-3D provided improved visual quality, clarity, and more precise guidance overall. Real-time audio instruction was reported as being particularly useful, as was the use of the object rotation and zoom functions which were associated with improving user confidence particularly when carrying out more challenging tasks.

CONCLUSIONS

This study reveals that older adults using guidetomeasure-3D achieved improved levels of accuracy and efficiency along with improved satisfaction and increased levels of confidence compared with the 2D paper-based equivalent. These results are significant and promising for overcoming HEFAP equipment abandonment issue. Furthermore they constitute an important step towards overcoming challenges associated with older adult patients, the digitisation of healthcare, and realising the enablement of patient self-care and management via the innovative use of mobile technologies. Numerous opportunities for the generalisability and transferability of the findings of this research are also proposed. Future research will explore the extent to which mobile 3D visualisation technologies may be utilised to optimise the clinical utility of HEFAP when deployed by clinicians.

Dual task performance and history of falls in community-dwelling older adults

INTRODUCTION

Falls are a common problem for older adults, and the identification of people at high risk of falling is a major challenge to health systems.

OBJECTIVE

To evaluate the association between the history of falls and single-task Timed Up and Go Test (single TUG) or dual-task TUG variables.

METHODS

Three hundred seventy seven community-dwelling older persons, with ages ranging from 65 and 92 years, participated in this cross-sectional study. Each participant performed two tests: single TUG and dual TUG. The cognitive task for dual TUG consisted of counting backward by one from 100 while performing the test. The number of cognitive errors, cognitive stops and motor stops were recorded. A new variable comprising time, errors and stops in the dual TUG was computed.

RESULTS

The number of falls was significantly associated with mean single and dual TUG performance, mean cognitive errors, mean cognitive stops and mean motor stops. The score in the single TUG time was not able to significantly classify participants as fallers or non-fallers in any of the sexes. On the other hand, the variable "dual TUG time spent adding cognitive stops and cognitive errors" achieved the best ability to classify women as fallers or non-fallers, while "dual task cost" and "dual TUG time spent adding cognitive stops" were the best variables to classify men.

CONCLUSIONS

Dual TUG including cognitive stops and cognitive errors may be more capable than the single TUG to detect differences and accurately classify fallers and non-fallers in the elderly.

Have outcomes improved in trauma patients age 90 years and older over the past decade: Experience at a level II trauma center

INTRODUCTION

Managing trauma in the elderly is challenging and requires a multidisciplinary team approach. The aim of this study is to characterize and compare outcomes in patients 90 years and older in the last two decades.

METHODS

Retrospective review of trauma patients 90 years and older admitted from 1996 to 2015. The patients were divided into two groups: Early Decade (ED) and Late Decade (LD).

RESULTS

A total of 1697 patients were recorded, 551 (ED) and 1146 (LD). The mean age was 92.92 ± 8(90-108)[ED] and 92.9 ± 2.7(90-105)[LD] years. The most common mechanism and type of injury was falls and extremity trauma. Hospital length of stay (LOS) was shorter in the LD. There was no significant difference in in-hospital mortality or ICU LOS.

CONCLUSION

Trauma admission has increased in the last decade. However, in-hospital mortality remains low. It is important for multidisciplinary teams to allocate resources to treat this elderly population.

Prevalence of vision loss among hospital in-patients; a risk factor for falls?

PURPOSE

Despite poor vision being a risk factor for falls, current hospital policies and practices often do not include a vision assessment at patient admission or in the hospital's incident reporting system when a fall occurs. Our purpose was to document the prevalence of vision loss in hospital general medicine units to increase awareness of poor vision as a potential risk factor for falls that occur within the hospital, and inform future preventative practice.

METHODS

This cross-sectional study took place in medicine units of an acute care hospital. Participants were adult in-patients. Visual acuity (VA), contrast sensitivity and stereoacuity were measured, and patients were screened for field loss, extinction and neglect.

RESULTS

115 participants took part (average age 67 ± 17, 48% female). Overall, 89% had a visual impairment defined as being outside the age-norms for one or more vision measure, 62% had low vision, and 36% had vision loss equivalent to legal blindness [VA equal to or poorer than 1.0 logMAR (6/60, 20/200) or ≥10x below age-norms]. There was a considerable discrepancy between the prevalence of low vision and the percentage of patients who reported an ocular diagnosis that would result in visual loss (30%). Ten patients fell during the study period, and of these 100% had visual impairment, 90% had low vision and 60% had vision loss equivalent to legal blindness, which compares to 58%, 22% and 9% for non-fallers. Similar high prevalences were found in those whose reason for admission to the hospital was a fall (92%, 63% and 33% respectively).

CONCLUSIONS

Vision loss has a high prevalence among patients in hospital medicine units, and is higher still among those who fall. Since vision loss may be a contributing factor to falls that occur in hospitals, implementing an assessment of vision at hospital admission would be useful to alert staff to those patients who are at risk for falls due to poor vision, so that preventative measures can be applied.

Sex effects on the association between sarcopenia EWGSOP and osteoporosis in outpatient older adults: data from the SARCOS study

OBJECTIVE

The objective was to evaluate the association between sarcopenia (EWGSOP) and osteoporosis in older adults.

SUBJECTS AND METHODS

This is a cross sectional analysis of a baseline evaluation of the SARCopenia and OSteoporosis in Older Adults with Cardiovascular Diseases Study (SARCOS). Three hundred and thirty-two subjects over 65 years of age were evaluated. Sarcopenia was determined by EWGSOP flowchart and Osteoporosis was established by WHO's criteria. Physical function, comorbidities and medications were evaluated.

RESULTS

Women were older (79.8 ± 7.2 years) than men (78.21 ± 6.7 years) (p = 0.042). Osteoporosis occurred in 24.8% of men, and in 42.7% of women (p < 0.001); sarcopenia occurred in 25.5% of men and in 17.7%, of women (p = 0.103). Osteoporosis was diagnosed in 68% of sarcopenic women, however only 20.7% (p = 0.009) of women with osteoporosis had sarcopenia; in older men, 44.7% of individuals with sarcopenia presented osteoporosis and 42.9% (p = 0.013) of men with osteoporosis showed sarcopenia. In an adjusted logistic regression analyses for sarcopenia, osteoporosis presented a statistically significant association with sarcopenia in men [OR: 2.930 (95% CI: 1.044-8.237; p = 0.041)] but not in women [OR: 2.081 (0.787-5.5; p = 0.142)]; in the adjusted logistic regression analyses for osteoporosis, a statistically significant association occurred in men [OR: 2.984 (95% CI: 1.144-7.809; p = 0.025)], but not in women [OR: 2.093 (0.962-3.714; p = 0.137)].

CONCLUSION

According to sex, there are significant differences in the association between sarcopenia EWGSOP and osteoporosis in outpatient older adults. It is strong and significant in males; in females, despite showing a positive trend, it was not statistically significant.

Exploring the characteristics of the high-cost population from the family perspective: a cross-sectional study in Jiangsu Province, China

BACKGROUND

Across a range of healthcare settings, 5% of the population accounts for half of healthcare spending: these patients are identified as a 'high-cost population'. Characterising high-cost users is essential for predicting potential high-cost patients and the development of appropriate interventions to improve the management and financing of these patients.

OBJECTIVE

This cross-sectional study aimed to explore the characteristics of this high-cost population from a family perspective in China and provide suggestions for social health insurance policy development.

METHODS

This study used data from the Fifth Health Service Investigation of Jiangsu Province (2013), and 12 600 families were enrolled for analysis. Households whose medical expenditures were among the top 5% were identified to be high-cost families. A t-test, a Χ² test, and a binary logistic regression were used.

RESULTS

High-cost families (n=631, 5%) accounted for 44.9% of the total medical expenditure of sampled families. High-cost families had 3.2 members and 1.2 chronic disease patients per household, which is significantly more than the 2.9 members and 0.7 people in the remaining families, respectively (p<0.05). Bi-weekly emergency department visits and annual hospitalisations preceding the household investigation of high-cost families were 1.19 and 0.98 per household, which is significantly more than the 0.68 and 0.17 of the remaining families, respectively (p<0.05). A binary logistic regression indicated that the number of family members (OR 1.152), the number of chronic disease patients (OR 1.508), bi-weekly emergency department visits (OR 1.218), and annual hospitalisations (OR 4.577) were associated with high costs.

CONCLUSION

The 5% high-cost families in Jiangsu Province accounted for approximately half of medical expenditures. The effectiveness of Chinese Social Health Insurance in lowering high-cost families' risk of catastrophic health expenditure was modest. Policymakers need to ascertain the priority of lowering the burden of high-cost families' out-of-pocket expenses through improving the reimbursement proportion and reducing avoidable medical services.

Mobile three-dimensional visualisation technologies for clinician-led fall prevention assessments

The assistive equipment provision process is routinely carried out with patients to mitigate fall risk factors via the fitment of assistive equipment within the home. However, currently, over 50% of assistive equipment is abandoned by the patients due to poor fit between the patient and the assistive equipment. This paper explores clinician perceptions of an early stage three-dimensional measurement aid prototype, which provides enhanced assistive equipment provision process guidance to clinicians. Ten occupational therapists trialled the three-dimensional measurement aid prototype application; think-aloud and semi-structured interview data was collected. Usability was measured with the System Usability Scale. Participants scored three-dimensional measurement aid prototype as ‘excellent’ and agreed strongly with items relating to the usability and learnability of the application. The qualitative analysis identified opportunities for improving existing practice, including, improved interpretation/recording measurements; enhanced collaborative practice within the assistive equipment provision process. Future research is needed to determine the clinical utility of this application compared with two-dimensional counterpart paper-based guidance leaflets.

Fall Prevention Self-Assessments Via Mobile 3D Visualization Technologies: Community Dwelling Older Adults' Perceptions of Opportunities and Challenges

BACKGROUND

In the field of occupational therapy, the assistive equipment provision process (AEPP) is a prominent preventive strategy used to promote independent living and to identify and alleviate fall risk factors via the provision of assistive equipment within the home environment. Current practice involves the use of paper-based forms that include 2D measurement guidance diagrams that aim to communicate the precise points and dimensions that must be measured in order to make AEPP assessments. There are, however, issues such as "poor fit" of equipment due to inaccurate measurements taken and recorded, resulting in more than 50% of equipment installed within the home being abandoned by patients. This paper presents a novel 3D measurement aid prototype (3D-MAP) that provides enhanced measurement and assessment guidance to patients via the use of 3D visualization technologies.

OBJECTIVE

The purpose of this study was to explore the perceptions of older adults with regard to the barriers and opportunities of using the 3D-MAP application as a tool that enables patient self-delivery of the AEPP.

METHODS

Thirty-three community-dwelling older adults participated in interactive sessions with a bespoke 3D-MAP application utilizing the retrospective think-aloud protocol and semistructured focus group discussions. The system usability scale (SUS) questionnaire was used to evaluate the application's usability. Thematic template analysis was carried out on the SUS item discussions, think-aloud, and semistructured focus group data.

RESULTS

The quantitative SUS results revealed that the application may be described as having "marginal-high" and "good" levels of usability, along with strong agreement with items relating to the usability (P=.004) and learnability (P<.001) of the application. Four high-level themes emerged from think-aloud and focus groups discussions: (1) perceived usefulness (PU), (2) perceived ease of use (PEOU), (3) application use (AU) and (4) self-assessment (SA). The application was seen as a useful tool to enhance visualization of measurement guidance and also to promote independent living, ownership of care, and potentially reduce waiting times. Several design and functionality recommendations emerged from the study, such as a need to manipulate the view and position of the 3D furniture models, and a need for clearer visual prompts and alternative keyboard interface for measurement entry.

CONCLUSIONS

Participants perceived the 3D-MAP application as a useful tool that has the potential to make significant improvements to the AEPP, not only in terms of accuracy of measurement, but also by potentially enabling older adult patients to carry out the data collection element of the AEPP themselves. Further research is needed to further adapt the 3D-MAP application in line with the study outcomes and to establish its clinical utility with regards to effectiveness, efficiency, accuracy, and reliability of measurements that are recorded using the application and to compare it with 2D measurement guidance leaflets.

Is independence of older adults safe considering the risk of falls?

BACKGROUND

Falls affect approx. 30% of elderly population per year. They cause major injuries and reduce independence of the older adults' functioning. The main objective of the study was to evaluate the degree of independence and find the fall risk factors in the study group.

METHODS

The study included 506 - older adults. The study group included patients from GP clinics and members of two senior centers. The study duration was 12 months. Our study tools included EASY- Care Standard 2010 questionnaire, Abbreviated Mental Test Score (AMTS), Index Barthel, Instrumental Activities of Daily Living Scale (IADL), Geriatric Depression Scale (GDS), Timed Up and Go (TUG).

RESULTS

The study included 357 (70.6%) female and 149 (29.4%) male subjects. The mean age of the study group patients was 75.7 years ± 8.0. Most of the older adult subjects were independent in both basic (Index Barthel) and instrumental (IADL) activities. Gait fluency evaluated in TUG scale found slow and unsteady gait in 33.7% of the subjects. 27.5% of the subjects used mobility aids when walking. In the Risk of falls scale, 131 subjects (25.89%) were at risk of falls. According to logistic regression the main risk of fall determinants (p <0.05) in the study group were: age, previous falls, feet problems, lack of regular care, impaired vision, urinary incontinence, pain, sleeping disorders, and lowered mood.

CONCLUSIONS

Risk of falls increases in people less independent in terms of basic and complex life activities and in people with depression. Most of the risk factors can be modified. It is necessary to develop a standard procedure aimed at preventing falls in the elderly.

Reducing falls in a care home

Care home residents are 3 times more likely to fall than their community dwelling peers and 10 times more likely to sustain a significant injury as a result. 2 A project commenced at a care home in Aberdeen with the aim of reducing the number of falls by 20% by 30st April 2016 using the model for improvement. Qualitative data was gathered to establish staff belief about falls and their level of knowledge& understanding about falls risks and how to manage these. This informed the training which was delivered and iterative testing commenced with the introduction of the Lanarkshire Falls Risk/Intervention tool - where the multifactorial nature of a resident's falls risks are explored and specific actions to manage these are identified and implemented. Failure to meet PDSA predictions about sharing risk reducing actions with staff and length of time to complete the tool prompted a focus on communication and the processes whereby the tool is completed. "Teach back" was employed to highlight communication difficulties and ultimately the introduction of Huddles out improved the flow of information about residents and informed the Falls Risk/Intervention tool. 5 PDSAs were completed and within them multiple tests of change. The improvement shift came following a root cause analysis of the nature & cause of one resident's falls and applying the tool & communication processes. The average falls rate fell from 49 per 1000 occupied bed days to 23.6 and was sustained because of the attention to the importance of communication. The aim was achieved with a 36.6% reduction in Falls rate.

Effectiveness of Senior Dance on risk factors for falls in older adults (DanSE): a study protocol for a randomised controlled trial

INTRODUCTION

Strong evidence shows that exercise is effective to improve fall risk factors among older people. However, older people's participation and adherence to exercise programmes is suboptimal. Type of exercise and apathy are reported to be barriers to exercise participation, suggesting that new effective interventions are needed. The primary aim of this randomised controlled trial is to investigate the effect of Senior Dance plus brief education for falls prevention on balance among people aged 60 years or over, compared with a control group receiving only brief education.

METHODS AND ANALYSIS

This single-blind randomised controlled trial will involve 82 community-dwelling older people aged 60 years or over who are cognitively intact. Participants allocated to the intervention group will attend a single educational class on strategies to prevent falls, and will participate in a 12-week, twice-weekly group-based programme of Senior Dance. The Senior Dance consists of different choreographies, which include rhythmic and simple movements with rhythmic folk songs. Participants allocated to the control group will attend the same educational class that intervention group participants will receive, and will be instructed not to take part in any regular exercise programme. The primary outcome will be single-leg stance with eyes closed. Secondary outcomes include: Short Physical Performance Battery, Falls Efficacy Scale, Trail Making Test and the Montreal Cognitive Assessment. Continuous outcomes will be reported using mean (SD) or median (IQR), depending on the distribution of the data. The linear regression approach to analysis of covariance will be used to compare the mean effect between groups. All patients will be included in the analyses following an intention-to-treat approach.

ETHICS AND DISSEMINATION

Ethics approval has been granted by the Human Ethics Committee of the São Paulo State University (CAAE 48665215.9.0000.5402). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at conferences.

Fall risk screening in the elderly: A comparison of the minimal chair height standing ability test and 5-repetition sit-to-stand test

BACKGROUND

Successfully identifying older adults with a high risk of falling can be complicated, time consuming and not feasible in daily medical practice. This study compared the effectiveness of the Minimal Chair Height Standing Ability Test (MCHSAT) and 5-repetition sit-to-stand tst (5R-STS) as fall risk-screening instruments for the elderly.

METHODS

167 community-dwelling older adults (mean age=83.6±7.3years) were interviewed for demographics, fall history, cognition, and mobility status. MCHSAT performance was assessed using a chair whose seat height was modifiable by increments of 5cm, starting at 47cm and lowering after each successful attempt. 5R-STS performance was assessed by recording the time it took to rise and sit back down five consecutive times from a chair of 47cm high. Operating Receiving Characteristic (ROC) curves and Area under the Curve (AUC) were calculated for each test as well as for sub-groups of participants classified based on medical comorbidities (e.g. cardiac disease/stroke, lower limb arthritis).

RESULTS

The MCHSAT and 5R-STS were equally effective fall-risk screening instruments for the overall population (AUC (95% CI)=0.72 (0.63-0.82) and 0.73(0.64-0.81) respectively). The 5R-STS was more effective than the MCHSAT for participants suffering from lower limb arthritis (AUC (95% CI)=0.81(0.70-0.92) and 0.71(0.58-0.85) respectively) while the opposite was true for participants with a history of cardiac disease or stroke (AUC (95% CI)=0.59 (0.44-0.80) and 0.65 (0.47-0.84) respectively).

CONCLUSION

Due to their simplicity and quick administration time, the MCHSAT and 5R-STS are equally suitable for implementation in clinical settings.

Unintentional injuries treated in hospital emergency departments among persons aged 65 years and older, United States, 2006-2011

INTRODUCTION

With the aging of the United States population, unintentional injuries among older adults, and especially falls-related injuries, are an increasing public health concern.

METHODS

We analyzed emergency department (ED) data from the Nationwide Emergency Department Sample, 2006-2011. We examined unintentional injury trends by 5-year age groups, sex, mechanism, body region, discharge disposition, and primary payer. For 2011, we estimated the medical costs of unintentional injury and the distribution of primary payers, plus rates by injury mechanisms and body regions injured by 5-year age groups.

RESULTS

From 2006 to 2011, the age-adjusted annual rate of unintentional injury-related ED visits among persons aged ≥ 65 years increased significantly from 7987 to 8163, per 100,000 population. In 2011, 65% of injuries were due to falls. Rates for fall-related injury ED visits increased with age and the highest rate was among those aged ≥ 100. Each year, about 85% of unintentional injury-related ED visits in this population were expected to be paid by Medicare. In 2011, the estimated lifetime medical cost of unintentional injury-related ED visits among those aged ≥ 65 years was $40 billion.

CONCLUSION

Increasing rates of ED-treated unintentional injuries, driven mainly by falls among older adults, will challenge our health care system and increase the economic burden on our society. Prevention efforts to reduce falls and resulting injuries among adults aged ≥ 65 years have the potential to increase well-being and reduce health care spending, especially the costs covered by Medicare.

PRACTICAL APPLICATIONS

With the aging of the U.S. population, unintentional injuries, and especially fall-related injuries, will present a growing challenge to our health care system as well as an increasing economic burden. To counteract this trend, we must implement effective public health strategies, such as increasing knowledge about fall risk factors and broadly disseminating evidence-based injury and fall prevention programs in both clinical and community settings.

Cost-effectiveness of droxidopa in patients with neurogenic orthostatic hypotension: post-hoc economic analysis of Phase 3 clinical trial data

OBJECTIVE

Falls are associated with neurogenic orthostatic hypotension (nOH) and are an economic burden on the US healthcare system. Droxidopa is approved by the US FDA to treat symptomatic nOH. This study estimates the cost-effectiveness of droxidopa vs standard of care from a US payer perspective.

METHODS

A Markov model was used to predict numbers of falls and treatment responses using data from a randomized, double-blind trial of patients with Parkinson's disease and nOH who received optimized droxidopa therapy or placebo for 8 weeks. The severity of falls, utility values, and injury-related costs were derived from published studies. Model outcomes included number of falls, number of quality-adjusted life-years (QALYs), and direct costs. Incremental cost-effectiveness ratios (ICERs) were calculated. Outcomes were extrapolated over 12 months.

RESULTS

Patients receiving droxidopa had fewer falls compared with those receiving standard of care and gained 0.33 QALYs/patient. Estimated droxidopa costs were $30,112, with estimated cost savings resulting from fall avoidance of $14,574 over 12 months. Droxidopa was cost-effective vs standard of care, with ICERs of $47,001/QALY gained, $24,866 per avoided fall with moderate/major injury, and $1559 per avoided fall with no/minor injury. The main drivers were fall probabilities and fear of fall-related inputs.

LIMITATIONS

A limitation of the current study is the reliance on falls data from a randomized controlled trial where the placebo group served as the proxy for standard of care. Data from a larger patient population, reflecting 'real-life' patient use and/or comparison with other agents used to treat nOH, would have been a useful complement, but these data were not available.

CONCLUSION

Using Markov modeling, droxidopa appears to be a cost-effective option compared with standard of care in US clinical practice for the treatment of nOH.

The cost of falls

Purpose

– The purpose of this paper is to explore the whole system cost of the care pathway for older people (aged 65-years old and over) admitted to hospitals as a result of falls in Torbay, a community of 131,000 in the southwest of England with a high proportion of older residents, over a two-year period.

Design/methodology/approach

– The paper analysed patient-level linked acute hospital, community care and local authority-funded social care data to track patients’ care costs – for those patients admitted to an acute hospital due to their fall – in the 12 months before and after their fall.

Findings

– On average, the cost of hospital, community and social care services for each admitted for a fall were almost four times as much in the 12 months after admission, than the cost of the admission itself. Over the 12 months that followed admission for falls, costs were 70 per cent higher than in the 12 months before the fall. The most dramatic increase was in community health care costs (160 per cent), compared to a 37 per cent increase in social care costs and a 35 per cent increase in acute hospital care costs. For patients who had a minor fall and those who survived 12 months after the fall, the costs of care home services increased significantly; for patients with hip fracture, the costs of community care services increased significantly; for patients who did not survive 12 months after the fall, the cost of acute inpatient and community health visits increased significantly.

Originality/value

– This is the only study that has assessed the costs across the acute hospital, community care and social care pathway for this group of patients, in an English population. This will help commissioners and providers understand and develop better-integrated responses to frail elderly patients needs.
