Falls amongst older people in Southeast Asia: a scoping review.

OBJECTIVES: The older population in the Southeast Asian region is accelerating and is expected to surpass the proportion of the ageing population in North America and Europe in the future. This study aims to identify the research literature related to falls among older people in Southeast Asia, to examine current practice and discuss the future direction on falls prevention and interventions in the region. STUDY DESIGN: A scoping review design was used. METHODS: A systematic literature search was conducted using the Medline, CINAHL, AMED, Ageline, PsycINFO, Web of Sciences, Scopus, Thai-Journal Citation Index, MyCite and trial registries databases. RESULTS: Thirty-seven studies and six study protocols were included, from Thailand, Malaysia, Singapore, Vietnam, Indonesia and the Philippines. One-sixth of the studies involved interventions, while the remainder were observational studies. The observational studies mainly determined the falls risk factors. The intervention studies comprised multifactorial interventions and single interventions such as exercises, educational materials and visual correction. Many of the studies replicated international studies and may not have taken into account features unique to Southeast Asia. CONCLUSION: Our review has revealed studies evaluating falls and management of falls in the Southeast Asian context. More research is required from all Southeast Asian countries to prepare for the future challenges of managing falls as the population ages.

Evaluating the effectiveness of a home-based exercise programme delivered through a tablet computer for preventing falls in older community-dwelling people over 2†years: study protocol for the Standing Tall randomised controlled trial.

INTRODUCTION: In order to prevent falls, older people should exercise for at least 2 h per week for 6 months, with a strong focus on balance exercises. This article describes the design of a randomised controlled trial to evaluate the effectiveness of a home-based exercise programme delivered through a tablet computer to prevent falls in older people. METHODS AND ANALYSIS: Participants aged 70 years or older, living in the community in Sydney will be recruited and randomly allocated to an intervention or control group. The intervention consists of a tailored, home-based balance training delivered through a tablet computer. Intervention participants will be asked to complete 2 h of exercises per week for 2 years. Both groups will receive an education programme focused on health-related information relevant to older adults, delivered through the tablet computer via weekly fact sheets. Primary outcome measures include number of fallers and falls rate recorded in weekly fall diaries at 12 months. A sample size of 500 will be necessary to see an effect on falls rate. Secondary outcome measures include concern about falling, depressive symptoms, health-related quality of life and physical activity levels (in all 500 participants); and physiological fall risk, balance, functional mobility, gait, stepping and cognitive performance (in a subsample of 200 participants). Adherence, acceptability, usability and enjoyment will be recorded in intervention group participants over 2 years. Data will be analysed using the intention-to-treat principle. Secondary analyses are planned in people with greater adherence. Economic analyses will be assessed from a health and community care provider perspective. ETHICS AND DISSEMINATION: Ethical approval was obtained from UNSW Ethics Committee in December 2014 (ref number HC#14/266). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at international conferences. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN)12615000138583.

Does a fall prevention educational programme improve knowledge and change exercise prescribing behaviour in health and exercise professionals? A study protocol for a randomised controlled trial.

INTRODUCTION: Falling in older age is a serious and costly problem. At least one in three older people fall annually. Although exercise is recognised as an effective fall prevention intervention, low numbers of older people engage in suitable programmes. Health and exercise professionals play a crucial role in addressing fall risk in older adults. This trial aims to evaluate the effect of participation in a fall prevention educational programme, compared with a wait-list control group, on health and exercise professionals' knowledge about fall prevention and the effect on fall prevention exercise prescription behaviour and confidence to prescribe the exercises to older people. METHODS AND ANALYSIS: A randomised controlled trial involving 220 consenting health and exercise professionals will be conducted. Participants will be individually randomised to an intervention group (n=110) to receive an educational workshop plus access to internet-based support resources, or a wait-list control group (n=110). The two primary outcomes, measured 3 months after randomisation, are: (1) knowledge about fall prevention and (2) self-perceived change in fall prevention exercise prescription behaviour. Secondary outcomes include: (1) participants' confidence to prescribe fall prevention exercises; (2) the proportion of people aged 60+ years seen by trial participants in the past month who were prescribed fall prevention exercise; and (3) the proportion of fall prevention exercises prescribed by participants to older people in the past month that comply with evidence-based guidelines. Outcomes will be measured with a self-report questionnaire designed specifically for the trial. ETHICS AND DISSEMINATION: The trial protocol was approved by the Human Research Ethics Committee, The University of Sydney, Australia. Trial results will be disseminated via peer reviewed journals, presentations at international conferences and participants' newsletters. TRIAL REGISTRATION NUMBER: Trial protocol was registered with the Australian and New Zealand Clinical Trials Registry (Number ACTRN12614000224628) on 3 March 2014.

Use of the Tailored Activities Program to reduce neuropsychiatric behaviors in dementia: an Australian protocol for a randomized trial to evaluate its effectiveness.

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) are often considered to be the greatest challenge in dementia care, leading to increased healthcare costs, caregiver burden, and placement into care facilities. With potential for pharmacological intervention to exacerbate behaviors or even lead to mortality, the development and rigorous testing of non-pharmacological interventions is vital. A pilot of the Tailored Activities Program (TAP) for reducing problem behaviors in people with dementia was conducted in the United States with promising results. This randomized trial will investigate the effectiveness of TAP for reducing the burden of BPSD on persons with dementia and family caregivers within an Australian population. This trial will also examine the cost-effectiveness and willingness to pay for TAP compared with a control group. METHODS: This randomized trial aims to recruit 180 participant dyads of a person with dementia and their caregivers. Participants will have a diagnosis of dementia, exhibit behaviors as scored by the Neuropsychiatric Inventory, and the caregiver must have at least 7 h per week contact. Participants will be randomly allocated to intervention (TAP) or control (phone-based education sessions) groups, both provided by a trained occupational therapist. Primary outcome measure will be the revised Neuropsychiatric Inventory - Clinician rating scale (NPI-C) to measure BPSD exhibited by the person with dementia. CONCLUSIONS: This trial investigates the effectiveness and cost-effectiveness of TAP within an Australian population. Results will address a significant gap in the current Australian community-support base for people living with dementia and their caregivers.

Reconstructing the fall: individual, behavioural and contextual factors associated with falls in individuals with intellectual disability.

BACKGROUND: Falls are a significant and recurrent problem for individuals with intellectual disability (ID). There has been little exploration of the fall event from the perspective of the individual who falls or their carers. Research has focused predominantly on personal risk factors, leaving the behavioural and contextual analysis of falls much less understood. This study aimed to identify these additional factors as well as briefly explore the fall experience for individuals and their carers. METHOD: A qualitative design was used incorporating fall reconstructions and ethnographic-style interviews conducted in the home setting. Nine people with ID and their carers/family member participated: five pairs were living at home and four were in out-of-family-home settings. Interviews were recorded, transcribed verbatim and major themes identified via thematic analysis. RESULTS: We identified 17 themes that contributed to falls and fell under the three headings of individual, behavioural or contextual factors. Themes include decreased physical capacity, unsafe behaviours, limited hazard awareness and the impact of others in the home on an individual's fall behaviours. Additionally, families and individuals identified a number of consequences and adaptations which they implemented to alleviate possible fall impact. CONCLUSIONS: Qualitative interviews, observational methods and carer assistance are valuable in offering insight into understanding the individual, behavioural and contextual factors associated with falls in people with ID. The fall reconstruction technique may be a useful supplement when evaluating intrinsic risk in programmes designed to reduce falls.

Disability in atypical parkinsonian syndromes is more dependent on memory dysfunction than motor symptoms.

BACKGROUND: There is a gap in the systematic description and investigation of functional disability in corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP). Additionally, the relations between disability, apraxia, cognitive and behavioural changes are not well understood in atypical parkinsonian syndromes. METHODS: Fifty patients were included in this study (CBS = 18; PSP = 11), including a subgroup of primary progressive aphasia-nonfluent variant (PPA-nfv = 21) who were used as a control group given the clinic-pathological overlap. Functional disability (basic and instrumental activities of daily living), general cognition and behavioural changes were evaluated at baseline, with a subgroup of patients being reassessed after 16 months. RESULTS: The corticobasal syndrome group had the most marked disability in basic activities in comparison to progressive supranuclear palsy and primary progressive aphasia-nonfluent variant. Longitudinal decline was marked for all three groups. In a linear regression examining factors behind functional disability in CBS and PSP, memory dysfunction emerged as the main factor (48.5%), followed by apraxia (14.9%) and atypical parkinsonian symptoms (9.6%). CONCLUSIONS: Memory dysfunction is the most important factor in functional disability in CBS and PSP, which has to be taken into consideration in disease management, prognosis and planning of services to fully address patients' and families' needs.

Activities of daily living in progressive non-fluent aphasia, logopenic progressive aphasia and Alzheimer's disease.

BACKGROUND/AIMS: This study examined functional changes in progressive non-fluent aphasia (PNFA) and logopenic progressive aphasia (LPA) and Alzheimer's disease (AD) and the association between function, cognition and behaviour. METHODS: 59 patients were assessed with the Disability Assessment of Dementia (DAD), Addenbrooke's Cognitive Examination Revised (ACE-R) and the Cambridge Behavioural Inventory Revised (CBI-R). RESULTS: No differences between groups in basic and instrumental activities of daily living (ADLs), and total ACE-R scores were found; there were correlations between total DAD and ACE-R scores for PNFA and LPA. Over 12 months, PNFA showed the marked decline of basic ADLs, whereas all three groups showed marked decline of instrumental ADLs. CONCLUSION: PNFA, LPA and AD appear functionally similar when matched for disease duration. The rate of decline of ADLs depends, however, on disease diagnosis.

Incidence of and risk factors for falls among adults with an intellectual disability.

BACKGROUND: Falls among people with intellectual disability (ID) occur at a younger age than the general population and are a significant cause of injury and hospitalisation. There is very limited research investigating risk factors for falls among people with ID and none with people living outside of formal care arrangements, either independently or with their family.We used a medical chart audit to identify the incidence and risk factors for falls among people with ID living in a variety of settings. METHODS: We retrospectively identified 114 consecutive patients, aged 18 years and over who attended a clinic for people with developmental disabilities within a 15-month period. Fall information was measured by carer recall of falls in the past 12 months. Potential risk factors were extracted from medical reports and a patient information questionnaire. Potential predictors were identified using univariate analysis and entered into a multiple logistic regression. RESULTS: Of 114 participants, 39 (34%) reported a fall in the previous 12 months.The number of reported falls was similar for formal care and non-formal care arrangements.The vast majority of fallers (84%) reported sustaining an injury from a fall and many potential risk factors were identified. Multivariate analysis revealed having seizures in the past 5 years, a history of fracture and increasing age were risk factors for falls. CONCLUSIONS: Falls are a significant health concern for adults with ID of all ages as a result of their incidence and the resulting injuries. Falls appear to be equally an issue for people residing in formal and non-formal care accommodation. Further research is needed to develop screening tools and interventions for this population.

Vision screening for frail older people: a randomised trial.

AIM: To assess the effects of vision screening, and subsequent management of visual impairment, on visual acuity and vision-related quality of life among frail older people. DESIGN: Randomised controlled trial. SETTING: Community in Sydney, Australia. PARTICIPANTS: 616 men and women aged 70 years and over (mean age 81 years) recruited mainly from people attending outpatient aged care services. CONTROL: No vision assessment or intervention INTERVENTIONS: Comprehensive vision and eye examinations conducted by an optometrist. Three hundred subjects were seen by the study optometrist, with 146 judged to need treatment for a vision or eye problem. The optometrist arranged new glasses for 92 subjects; 24 were referred for a home visit by an occupational therapist; 17 were referred for glaucoma management; and 15 were referred for cataract surgery. MAIN OUTCOME MEASURE: Distance and near visual acuity (logMAR) and composite scores on the 25-item version of the National Eye Institute Visual Function Questionnaire, both assessed at a 12-month follow-up home visit. RESULTS: After 12 months' follow-up, the mean (logMAR) distance visual acuity was 0.27 in the intervention group and 0.25 in the control group (p = 0.32). The mean (logMAR) near visual acuities were -0.01 in the intervention group and -0.03 in the control group (p = 0.26). The mean composite score on the National Eye Institute Visual Function Questionnaire was 84.3 in the intervention group and 86.4 in the control group (p = 0.49). CONCLUSIONS: Vision screening by an optometrist for frail older people living in the community in Australia does not lead to improvements in vision or vision-related quality of life after 1 year's follow-up.

Effects of diet and exercise on plasma vitamin D (25(OH)D) levels in Vietnamese immigrant elderly in Sydney, Australia.

Vitamin D deficiency may be associated with osteoporosis and fractures in the elderly. In Australia where there is a sizeable Vietnamese population, research has not yet clarified the roles of diet, exercise and sun exposure in determining vitamin D status. Plasma samples for 25-hydroxy-vitamin D (25(OH)D); dietary intake of vitamin D and calcium; muscle strength and sun exposure were measured and weekly dairy intake, exercise levels and smoking habits were surveyed in free-living elderly of Vietnamese and Australian/British origin. There was marginal vitamin D deficiency (<37 nmol/L 25(OH)D) in 63% of Vietnamese but only in 37% of Australian/British born. Low dairy intake and no vigorous exercise were best predictors of vitamin D deficiency in Vietnamese, taking into account age, gender, dietary intake and sun exposure. Since these migrant elderly may not get adequate sun exposure due to either clothing customs or cultural norms that encourage fair (untanned) skin, it is important to encourage increased exercise and dairy intake.

Families and nursing home placements: a cross-cultural study.

With the aging of many populations, health care workers and families increasingly find themselves jointly involved in situations involving decisions about nursing home placements. How each approaches such situations is affected by beliefs and assumptions about the role of family members in the care of family members and the decision making process. This paper explores the responses of people from four cultural groups living in Australia (Anglo-Celtic Australian, Chinese, Greek, Lebanese) to a critical incident scenario about a Russian family in Australia faced with such a decision. The responses to this scenario were remarkably similar across the four cultural groups. All saw making such a decision as difficult, but the reasons for the difficulty suggest some interesting cross-cultural distinctions. Some groups viewed care of a family member more in terms of a social and role obligation while others addressed it as a personal responsibility. To not care for elderly parents in the home was accompanied by a sense of guilt among some respondents and a sense of public social shame among others. Ambivalence about nursing homes and placing a family member in a nursing home, culture change and cross-generational differences, and roles and role support were other important themes. The results are consistent with other data analysed in conjunction with the Intercultural Interaction Project. The findings from this research suggests a need to examine more closely the beliefs and assumptions associated with nursing home placements and one way to help students and health professionals to do so.

Adherence to occupational therapist recommendations for home modifications for falls prevention.

OBJECTIVE: This study examined adherence to home modification recommendations made by an occupational therapist and attempted to identify predictors of adherence. METHOD: An experienced occupational therapist visited the homes of 178 people (mean age = 764 years) to evaluate for and recommend appropriate home modifications for falls prevention. One year later, a research assistant visited these persons' homes to assess adherence. RESULTS: At least one home modification was recommended in 150 of the 178 homes visited. The most common recommendations were to remove mats and throw rugs (48%), to change footwear (24%), and to use a nonslip bathmat (21%). In the 121 homes revisited after 12 months, 419 home modifications had been recommended, and 216 (52%) were met with partial or complete adherence. The only significant predictors of adherence were a belief that home modifications can prevent falls and having help at home from relatives. CONCLUSION: A major barrier to adherence to home modification recommendations is that many older people do not believe that home modifications can reduce their risk of falling.

Managing risk and exerting control: determining follow through with falls prevention.

PURPOSE/METHOD: This study used in-depth interviews to explore the perspectives of nine older women who had not followed through with environmental modification recommendations to reduce their risk of falls in the home. RESULTS: It was found that the core concept of 'exerting control' provided an understanding of their experience following an occupational therapy home visit. Exerting control was a behavioural, cognitive and affective process whereby the women made decisions about whether or not to follow through with environmental modification recommendations based on their knowledge of environmental risks, perceptions of degree of risk, perceived ability to mediate these risks through behaviour and the degree of freedom she had in decision making. Exerting control meant that the women made daily choices about their home environment which increased or decreased the risk of falls with identified home hazards. CONCLUSION: The findings suggest that, for some women, health professionals need to understand and work with the phenomenon of exerting control, in order to work with clients to reduce environmental hazards.

Case-control study of hazards in the home and risk of falls and hip fractures.

The importance of environmental hazards in the home as risk factors for falls and fractures is uncertain. A case-control study was conducted, involving people aged 65 years and over referred to an occupational therapy department for home assessment. There were 52 subjects with a recent hip fracture, 43 fallers (subjects with two or more falls in the past year but no hip fracture), and 157 non-fallers (subjects without hip fracture and with fewer than two falls in the past year). Subjects' homes were assessed for environmental hazards by occupational therapists using a structured home assessment form comprising 35 potential hazards. Overall, the homes of fallers were no more hazardous than the homes of non-fallers. However, fallers with cognitive impairment had significantly more hazards in their homes than non-fallers with cognitive impairment. A wide range of environmental hazards was associated with hip fractures. Many of the findings of this study could be due to bias inherent in the case-control design. To overcome the inadequacies of observational studies for the investigation of home hazards and falls, randomized trials are recommended to determine if removing hazards reduces the risk of falls and fractures.

Usage and effectiveness of rails, bathing and toileting AIDS.

There is a lack of systematic follow-up on the usage or effectiveness of rails and aids to elderly persons or persons with disability. One hundred and forty-four persons, mostly elderly, responded to a mailed questionnaire. Factors associated with usage and non-usage of commonly used bathing and toileting aids and rails, and rails used for access to and from the home were investigated, including reasons for non-usage, equipment acceptance, perceived benefit, ergonomic factors and equipment reliability. The questionnaire was shown to have high internal consistency. Usage rates were high, 86% for rails and 76% for aids. Non-usage was largely attributed to change in functional status. There were also some specific areas of dissatisfaction indicated, including issues of aid prescription, methods of assessing rail placement, and design of equipment.
