Abstract
INTRODUCTION osteoarthritis (OA) of knee has been reported as a risk factor for falls and reduced balance in the elderly. This systematic review evaluated the effectiveness of physical therapies in improving balance and reducing falls risk among patients with knee OA. METHODS a computerised search was performed to identify relevant studies up to November 2013. Two investigators identified eligible studies and extracted data independently. The quality of the included studies was assessed by the PeDro score. RESULTS a total of 15 randomised controlled trials involving 1482 patients were identified. The mean PeDro score was 7. The pooled standardised mean difference in balance outcome for strength training = 0.3346 (95% CI: 0.3207-0.60, P = 0.01 < 0.00001, P for heterogeneity = 0.85, I(2) = 0%). Tai Chi = 0.7597 (95% CI: 0.5130-1.2043, P<=0.0014, P for heterogeneity = 0.26, I(2) = 0%) and aerobic exercises = 0.6880 (95% CI: 0.5704-1.302, P < 0.00001, P for heterogeneity = 0.71, I(2) = 0%). While pooled results for falls risk outcomes in, strength training, Tai chi and aerobics also showed a significant reduction in reduced risk of falls significantly with pooled result 0.55 (95% CI: 0.41-0.68, P < 0.00001, P for heterogeneity = 0.39, I(2) = 6%). CONCLUSION strength training, Tai Chi and aerobics exercises improved balance and falls risk in older individuals with knee OA, while water-based exercises and light treatment did not significantly improve balance outcomes. Strength training, Tai Chi and aerobics exercises can therefore be recommended as falls prevention strategies for individuals with OA. However, a large randomised controlled study using actual falls outcomes is recommended to determine the appropriate dosage and to measure the potential benefits in falls reduction.

Abstract
BACKGROUND Single or frequent falls lead to increased morbidity due to fall-related injury, fear of falling, impairments in quality of life and loss of independence. To assess the impact of falls, prevalence data are essential. METHODS In 2006, a telephone survey was performed in a random sample of 1270 inhabitants of the city of Herne, Germany, aged 40 years or older. Participants were asked about falls during the previous 4 weeks and 6 and 12 months, respectively. A fall was defined as an unexpected event in which the individual comes to rest on the ground, floor or a lower level. Participants were also asked about pain and whether or not a medical diagnosis of osteoporosis had ever been made. Standardized prevalences and odds ratios (OR) with 95 % confidence interval are reported. RESULTS In total, 862 (67.9 %) adults participated. Participants were significantly older than non-participants and more often female than male. Prevalences standardized for the population of Herne for at least one fall within the previous 4 weeks or 12 months or two or more falls within 12 months, respectively, were 3.1 %, 12.1 %, and 4.5 %. Women were more often affected than men. A total of 2.3 % participants reported both at least one fall and a medical diagnosis of osteoporosis. The prevalence of falls increased with increasing age and was also related to musculoskeletal pain. CONCLUSIONS Our estimates indicate that single and multiple falls affect a substantial proportion of adults in the urban population. Risk groups such as older adults and females with osteoporosis might represent a target group when considering measures for fall prevention.

Abstract
OBJECTIVES To examine the current state of cancer prehabilitation care and the impact that it may have on health-related and financial outcomes. DATA SOURCES Clinical trials, reviews and meta-analyses. CONCLUSION Research demonstrates that prehabilitation interventions may improve physical and/or psychological outcomes and help patients function at a higher level throughout their cancer treatment. Establishing a baseline status at diagnosis provides an opportunity to gain insight into the burden that cancer and its treatment can place on survivors with respect to physical and psychological impairments, function, and disability. Targeted interventions may reduce the incidence and/or severity of future impairments that often lead to reduced surgical complications, hospital lengths of stay, hospital readmissions, and overall health care costs. Thus, cancer prehabilitation is an opportunity to positively impact patient health-related and financial outcomes from diagnosis onward and, by decreasing the financial impact that cancer can have on individuals, may prove to be a sound investment for patients, hospitals, payers and society. IMPLICATIONS FOR NURSING PRACTICE Nurses, and particularly navigators, have an opportunity to significantly impact care through patient screening, prehabilitation assessments, documentation of baseline patient status and, in some cases, especially when impairments are not present at baseline, provide interventions designed to improve physical and psychological health before the start of upcoming oncology treatments and reduce the likelihood of patients developing future impairments.

Abstract
Since falls are a major public health problem in an aging society, there is considerable demand for low-cost fall detection systems. One of the main reasons for non-acceptance of the currently available solutions by seniors is that the fall detectors using only inertial sensors generate too much false alarms. This means that some daily activities are erroneously signaled as fall, which in turn leads to frustration of the users. In this paper we present how to design and implement a low-cost system for reliable fall detection with very low false alarm ratio. The detection of the fall is done on the basis of accelerometric data and depth maps. A tri-axial accelerometer is used to indicate the potential fall as well as to indicate whether the person is in motion. If the measured acceleration is higher than an assumed threshold value, the algorithm extracts the person, calculates the features and then executes the SVM-based classifier to authenticate the fall alarm. It is a 365/7/24 embedded system permitting unobtrusive fall detection as well as preserving privacy of the user.

Abstract
BACKGROUND The primary aim of this paper is to describe the design of a project evaluating the effects of using a research-based strategy for managing housing adaptations (HAs). The evaluation targets clients' perspectives in terms of activity, participation, usability, fear of falling, fall incidence, use of mobility devices, and health-related quality of life, and determines the societal effects of HAs in terms of costs. Additional aims of the project are to explore and describe this strategy in relation to experiences and expectations (a) among clients and cohabitants and (b) occupational therapists in ordinary practice. METHODS/DESIGN This study is a quasi-experimental trial applying a multiphase design, combining quantitative and qualitative data. At the experimental sites, the occupational therapists (OTs) apply the intervention, i.e. a standardized research-based strategy for HA case management. At the control site, the occupational therapists are following their regular routine in relation to HA. Three municipalities in south Sweden will be included based on their population, their geographical dispersion, and their similar organizational structures for HA administration. Identical data on outcomes is being collected at all the sites at the same four time points: before the HA and then 3, 6, and 12 months after the HA. The data-collection methods are semi-structured qualitative interviews, observations, clinical assessments, and certificates related to each client's HA. DISCUSSION The intervention in this study has been developed and tested through many years of research and in collaboration with practitioners. This process includes methodological development and testing research aimed at identifying the most important outcomes and research targeting current HA case-management procedures in Swedish municipalities. When the study is completed, the results will be used for further optimization of the practice strategy for HA, in close collaboration with the data-collecting OTs.

Abstract
OBJECTIVES Injury is a major public health problem. While the impacts of injury on the injured person are well documented, there is relatively little knowledge about the impacts of injury on those individuals and groups in the community connected to the injured person. This study seeks to describe this breadth of research using a meta-review methodology. STUDY DESIGN Systematic meta-review. METHODS To gain a better understanding of the known impacts of injury on family, community and society, a systematic meta-review of injury outcomes research literature was conducted. Seventy-eight peer-reviewed published literature reviews were included in the meta-review. RESULTS Of these, 70 reported outcomes at the level of the injured person including mortality, body functions, activity and participation limitations. Nine reviews reported impacts at the level of the community including impacts on family members, work colleagues and carers. Six studies reported impacts at the societal level including economic, health system and injury compensation system impacts. CONCLUSIONS In summary, the meta-review identified a substantial body of knowledge at the individual level outcomes of injury, and a relative lack of information regarding the community and societal impacts of injury. An injury outcome framework is proposed on the basis of the findings of the meta-review to guide future research activity, particularly with regard to injury outcome domains where there is currently limited evidence. A comprehensive framework that takes account of all levels of impact is necessary for effective policies, systems and strategies to support recovery following injury.

Towards the importance of minimum toe clearance in level ground walking in a healthy elderly population. Gait Posture 2014; 40:727-9.

Abstract
Tripping is presumed to be the principal cause for falls during walking. At minimum toe clearance, the potential for trip-related falls is considered to be highest. Thus, controlling minimum toe clearance is essential for walking without tripping. In theory, the central nervous system should therefore give priority to accurate control of the variability in minimum toe clearance, as compared to other gait parameters, since people tend to only modify variability in any given task if it interferes with the task performance. The aim of this study was to determine whether elderly individuals show less increase in variability of minimum toe clearance during a dual-task condition (where an increase of gait variability is provoked), while allowing a larger range of variability in the other gait parameters. Forty elderly participants walked back and forth on a 25 m long track for five minutes. They then walked a second time performing an additional cognitive task. The variability in stride time, stride length and minimum toe clearance as well as dual-task costs of each gait parameter were calculated for each walk. The variability in minimum toe clearance did not change during dual task-walking, whereas the variability of stride length and stride time increased, showing dual-task costs of about 66% and 84%, respectively. To avoid additional detrimental load on the central nervous system, the modification of task-irrelevant variability may be tolerated during dual-task conditions, whereas minimum toe clearance is controlled with high priority.

Abstract
Hyponatremia is especially common in older people. Recent evidence highlights that even mild, chronic hyponatremia can lead to cognitive impairment, falls and fractures, the latter being in part due to bone demineralization and reduced bone quality. Hyponatremia is therefore of special significance in frail older people. Management of hyponatremia in elderly individuals is particularly challenging. The underlying cause is often multi-factorial, a clear history may be difficult to obtain and clinical examination is unreliable. Established treatment modalities are often ineffective and carry considerable risks, especially if the diagnosis of underlying causes is incorrect. Nevertheless, there is some evidence that correction of hyponatremia can improve cognitive performance and postural balance, potentially minimizing the risk of falls and fractures. Oral vasopressin receptor antagonists (vaptans) are a promising innovation, but evidence of their safety and effect on important clinical outcomes in frail elderly individuals is limited.

Abstract
Falls are the leading cause of injuries among older adults, aged 65 years and older. Furthermore, falls are an increasing public health problem because of ageing populations worldwide due to an increase in the number of older adults, and an increase in life expectancy. Numerous studies have identified risk factors and investigated possible strategies to prevent (recurrent) falls in community-dwelling older people and those living in long-term care facilities. Several types of drugs have been associated with an increased fall risk. Since drugs are a modifiable risk factor, periodic drug review among older adults should be incorporated in a fall prevention programme.

Abstract
Hyponatraemia is the commonest electrolyte abnormality seen in clinical practice, and is especially prevalent in frail, older people. However, the serious implications of hyponatraemia in this age group are seldom recognized by clinicians. Hyponatraemia is associated with osteoporosis, impaired balance, falls, hip fractures and cognitive dysfunction. Even mild, apparently asymptomatic hyponatraemia is associated with prolonged stays in hospital, institutionalization and increased risk of death. Emerging evidence of the potential benefits of improved treatment of hyponatraemia is slowly generating renewed clinical interest in this area. The development of specific vasopressin-2 receptor antagonists (vaptans) has the potential to revolutionize the management of hyponatraemia, in particular for the syndrome of inappropriate antidiuretic hormone. However, challenges remain for the attending physician. Diagnosing the cause or causes of hyponatraemia in older people is difficult, and incorrect diagnosis can lead to treatment that worsens the electrolyte imbalance. Established treatments are often poorly tolerated and patient outcomes remain poor, and the role of vaptans in the treatment of older people is unclear. This review summarizes the existing evidence base and highlights areas of controversy. It includes practical guidance for overcoming some common pitfalls in the management of the elderly patient with hyponatraemia.

Abstract
OBJECTIVE: To analyze the lesions diagnosed in victims of falls, comparing them with those diagnosed in other mechanisms of blunt trauma.METHODS: We conducted a retrospective study of trauma protocol charts (prospectively collected) from 2008 to 2010, including victims of trauma over 13 years of age admitted to the emergency room. The severity of injuries was stratified by the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS). Variables were compared between the group of victims of falls from height (Group 1) and the other victims of blunt trauma (Group 2). We used the Student t, chi-square and Fisher tests for comparison between groups, considering the value of p <0.05 as significant.RESULTS: The series comprised 4,532 cases of blunt trauma, of which 555 (12.2%) were victims of falls from height. Severe lesions (AISe"3) were observed in the extremities (17.5%), in the cephalic segment (8.4%), chest (5.5%) and the abdomen (2.9%). Victims of Group 1 had significantly higher mean age, AIS in extremities / pelvis, AIS in the thoracic segment and ISS (p <0.05). The group 1 had significantly (p <0.05) higher incidence of tracheal intubation on admission, pneumothorax, hemothorax, rib fractures, chest drainage, spinal trauma, pelvic fractures, complex pelvic fractures and fractures to the upper limbs.CONCLUSION: Victims of fall from height had greater anatomic injury severity, greater frequency and severity of lesions in the thoracic segment and extremities.

A cognitive dual task affects gait variability in patients suffering from chronic low back pain. Exp Brain Res 2014; 232:3509-13.

Abstract
Chronic pain and gait variability in a dual-task situation are both associated with higher risk of falling. Executive functions regulate (dual-task) gait variability. A possible cause explaining why chronic pain increases risk of falling in an everyday dual-task situation might be that pain interferes with executive functions and results in a diminished dual-task capability with performance decrements on the secondary task. The main goal of this experiment was to evaluate the specific effects of a cognitive dual task on gait variability in chronic low back pain (CLBP) patients. Twelve healthy participants and twelve patients suffering from CLBP were included. The subjects were asked to perform a cognitive single task, a walking single task and a motor-cognitive dual task. Stride variability of trunk movements was calculated. A two-way ANOVA was performed to compare single-task walking with dual-task walking and the single cognitive task performance with the motor-cognitive dual-task performance. We did not find any differences in both of the single-task performances between groups. However, regarding single-task walking and dual-task walking, we observed an interaction effect indicating that low back pain patients show significantly higher gait variability in the dual-task condition as compared to controls. Our data suggest that chronic pain reduces motor-cognitive dual-task performance capability. We postulate that the detrimental effects are caused by central mechanisms where pain interferes with executive functions which, in turn, might contribute to increased risk of falling.

Abstract
Background Around 30% to 62% of older individuals fall each year, with adverse consequences of falls being by no means limited to physical injury and escalating levels of dependence. Many older individuals suffer from a variety of adverse psychosocial difficulties related to falling including fear, anxiety, loss of confidence and subsequent increasing activity avoidance, social isolation and frailty. Such ‘fear of falling’ is common and disabling, but definitive studies examining the effective management of the syndrome are lacking. Cognitive behavioural therapy has been trialed with some success in a group setting, but there is no adequately powered randomised controlled study of an individually based cognitive behavioural therapy intervention, and none using non-mental health professionals to deliver the intervention. Methods/Design We are conducting a two-phase study examining the role of individual cognitive behavioural therapy delivered by healthcare assistants in improving fear of falling in older adults. In Phase I, the intervention was developed and taught to healthcare assistants, while Phase II is the pragmatic randomised controlled study examining the efficacy of the intervention in improving fear of falling in community-dwelling elders attending falls services. A qualitative process evaluation study informed by Normalization Process Theory is being conducted throughout to examine the potential promoters and inhibitors of introducing such an intervention into routine clinical practice, while a health economic sub-study running alongside the trial is examining the costs and benefits of such an approach to the wider health economy.

Abstract
This cross sectional study focused on how Postural Stability (PS) indicators: body sway deviation (BSD) and body sway velocity (BSV), change with age and their association with levels of social and physical activity. Observational study: 80 older adults (aged: 60-96) were purposefully recruited from two sources: the University of the Third Age (TAU) (n = 35) and a residential care home (CH) (n = 45). Differences in the indicators of PS, approximated through Centre of Pressure (COP) measurements, were assessed by the Romberg Stance Test (Test A) subsequently repeated on 10 cm foam surface (Test B), using a Kistler Dynamometric Platform. The RCH Group was older, had higher BMI and was less socially and physically active, showed more body sway in all indicators compared to TAU group. For all participants body sway velocity (BSV) was significantly correlated with age. The strength of correlation of body sway deviation (BSD) with age was also significant but not as strong. The findings indicate in line with previous studies that deterioration in BSV is associated with poor PS more than deterioration in BSD.

A population-based intervention for the prevention of falls and fractures in home dwelling people 65 years and older in South Germany: protocol. JMIR Res Protoc 2014; 3:e19.

Abstract
Background Falls and fall-related injuries pose a major threat to older peoples’ health, and are associated with increased morbidity and mortality. In the course of demographic changes, development and implementation of fall prevention strategies have been recognized as an urgent public health challenge. Various risk factors for falls and a number of effective interventions have been recognized. A substantial proportion of falls occur for people who are neither frail nor at high risk. Therefore, population-based approaches reaching the entire older population are needed. Objective The objective of the study presented is the development, implementation, and evaluation of a population-based intervention for the prevention of falls and fall-related injuries in a medium sized city in Germany. Methods The study is designed as a population-based approach. The intervention community is a mid sized city named Reutlingen in southern Germany with a population of 112,700 people. All community dwelling inhabitants 65 years and older are addressed. There are two main measures that are defined: (1) increase of overall physical activity, and (2) reduction of modifiable risk factors for falls such as deficits in strength and balance, home and environmental hazards, impaired vision, unsafe footwear, and improper use of assistive devices. The implementation strategies are developed in a participatory community planning process. These might include, for example, training of professionals and volunteers, improved availability of exercise classes, and education and raising awareness via newspaper, radio, or lectures. Results The study starts in September 2010 and ends in December 2013. It is evaluated primarily by process evaluation as well as by telephone survey. Conclusions Physical activity as a key message entails multiple positive effects with benefits on a range of geriatric symptoms. The strength of the design is the development of implementation strategies in a participatory community planning. The problems that we anticipate are the dependency on the stakeholders’ willingness to participate, and the difficulty of evaluating population-based programs by hard end points.

Fall-related emergency department admission: fall environment and settings and related injury patterns in 6357 patients with special emphasis on the elderly. ScientificWorldJournal 2014; 2014:256519. [PMID: 24723797 PMCID: PMC3958756 DOI: 10.1155/2014/256519] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2013] [Accepted: 01/23/2014] [Indexed: 11/29/2022] Open
Abstract
Principals. Throughout the world, falls are a major public health problem and a socioeconomic burden. Nevertheless there is little knowledge about how the injury types may be related to the aetiology and setting of the fall, especially in the elderly. We have therefore analysed all patients presenting with a fall to our Emergency Department (ED) over the past five years. Methods. Our retrospective data analysis comprised adult patients admitted to our Emergency Department between January 1, 2006, and December 31, 2010, in relation to a fall. Results. Of a total of 6357 patients 78% (n = 4957) patients were younger than 75 years. The main setting for falls was patients home (n = 2239, 35.3%). In contrast to the younger patients, the older population was predominantly female (56.3% versus 38.6%; P < 0.0001). Older patients were more likely to fall at home and suffer from medical conditions (all P < 0.0001). Injuries to the head (P < 0.0001) and to the lower extremity (P < 0.019) occurred predominantly in the older population. Age was the sole predictor for recurrent falls (OR 1.2, P < 0.0001). Conclusion. Falls at home are the main class of falls for all age groups, particularly in the elderly. Fall prevention strategies must therefore target activities of daily living. Even though falls related to sports mostly take place in the younger cohort, a significant percentage of elderly patients present with falls related to sporting activity. Falls due to medical conditions were most likely to result in mild traumatic brain injury.

Abstract
Background Although recommended for use in studies investigating falls in the elderly, the European Quality of Life Group instrument, EQ-5D, has not been widely used to assess the impact of falls on quality of life. The aim of this study was to investigate the association of single and frequent falls with EQ-5D rated quality of life in a sample of German community-dwelling seniors in primary care suffering a variety of concurrent chronic diseases and conditions. Methods In a cross-sectional study, a sample of community-dwelling seniors aged ≥ 72 years was interviewed by means of a standardised telephone interview. According to the number of self-reported falls within twelve months prior to interview, participants were categorised into one of three fall categories: no fall vs. one fall vs. two or more falls within twelve months. EQ-5D values as well as other characteristics were compared across the fall categories. Adjustments for a variety of concurrent chronic diseases and conditions and further variables were made by using multiple linear regression analysis, with EQ-5D being the target variable. Results In total, 1,792 participants (median age 77 years; 53% female) were analysed. The EQ-5D differed between fall categories. Participants reporting no fall had a mean EQ-5D score of 81.1 (standard deviation [s.d.]: 15.4, median: 78.3), while participants reporting one fall (n = 265; 14.8%) and participants with two or more falls (n = 117; 6.5%) had mean total scores of 77.0 (s.d.: 15.8, median: 78.3; mean difference to participants without a fall: -4.1, p < 0.05) and 72.1 (s.d.: 17.6, median: 72.5; mean difference: -9.0, p < 0.05), respectively. The mean difference between participants with one fall and participants with two or more falls was -4.9 (p < 0.05). Under adjustment for a variety of chronic diseases and conditions, the mean decrease in the total EQ-5D score was about -1.0 score point for one fall and about -2.5 points for two or more falls within twelve months. In quantity, this decrease is comparable to other chronic diseases adjusted for. Among the variables with the greatest negative association with EQ-5D ratings in multivariate analysis were depression and fear of falling. Conclusions The findings suggest that falls are negatively associated with EQ-5D rated quality of life independent of a variety of chronic diseases and conditions.

Abstract
AIM OF THE STUDY The goal of this study was to compare two types of rehabilitation for geriatric patients with femoral fracture in Germany, i.e. care in geriatric hospital departments (§109 SGB V) and care in geriatric out-of-hospital rehabilitation facilities (§111 SGB V). METHODS Based on claims data of the AOK ("Allgemeine Ortskrankenkasse"=local insurance fund) insurants with a documented hospital stay with discharge diagnosis fracture of the femur in 2007 (n=25,954) were included and allocated to the respective form of rehabilitative health care via the OPS (German procedure classification for inpatient procedures) procedure 8-550 (§109, n=2028) or via admission to a geriatric rehabilitation unit (§111, n=4061). Excess costs (costs in the first year after fracture--costs in the previous year), risk of rehospitalization due to femoral fracture, and risk of death during the 1-year follow-up were compared using multivariate regression analyses. RESULTS No significant differences were observed related to the outcomes rehospitalization due to femoral fracture and death. However, slight but significantly higher excess costs were observed in the health care type §109 (compared to §111) in patients with low excess costs. Moreover, insured members treated according to health care type §109 were more often receiving long-term care. CONCLUSION Further analyses including qualitative endpoints, e.g., achievements of rehabilitation aims, are warranted.

Abstract
Many measures aiming to assess the stability of human motion have been proposed in the literature, but still there is no commonly accepted way to define or quantify locomotor stability. Among these measures, orbital stability analysis via Floquet multipliers is still under debate. Some of the controversies concerning the use of this technique could lie in the absence of a standard implementation. The aim of this study was to analyse the influence of i) experimental measurement noise, ii) variables selected for the construction of the state space, and iii) number of analysed cycles on the outputs of orbital stability applied to walking. The analysis was performed on a 2-dimensional 5-link walking model and on a sample of 10 subjects performing long over-ground walks. Noise resulting from stereophotogrammetric and accelerometric measurement systems was simulated in the in-silico analysis. Maximum Floquet multipliers resulted to be affected by both number of analysed strides and state space composition. The effect of experimental noise was found to be slightly more potentially critical when analysing stereophotogrammetric data then when dealing with acceleration data. Experimental and model results were comparable in terms of overall trend, but a difference was found in the influence of the number of analysed cycles.

Abstract
Boosted by health consequences and the cost of falls in the elderly, this work develops and tests a novel algorithm and methodology to detect human impacts that will act as triggers of a two-layer fall monitor. The two main requirements demanded by socio-healthcare providers—unobtrusiveness and reliability—defined the objectives of the research. We have demonstrated that a very agile, adaptive, and energy-based anisotropic algorithm can provide 100% sensitivity and 78% specificity, in the task of detecting impacts under demanding laboratory conditions. The algorithm works together with an unsupervised real-time learning technique that addresses the adaptive capability, and this is also presented. The work demonstrates the robustness and reliability of our new algorithm, which will be the basis of a smart falling monitor. This is shown in this work to underline the relevance of the results.

Abstract
Purpose
– Despite the growing area of research involving falls in the residential care setting, the link between contextual and environmental factors in falls is poorly understood. This paper aims to draw upon existing research being undertaken in long-term care (LTC) in Metro Vancouver, Canada, with a particular focus on identifying contextual factors contributing to fall events.
Design/methodology/approach
– This paper presents the results of a qualitative observational analysis of video-captured data collected through a network of high-quality video systems in two LTC facilities. The research comprised workshops involving experienced researchers who reviewed six video sequences of fall events. The outcome of the workshops was a written narrative summarizing the discussion and researchers’ interpretation of fall sequences.
Findings
– The analysis indicates that there are a broad range of environmental, behavioral and situational factors that contribute to falls in LTC. This suggests that a limited conceptualization of a fall as an outcome of the person's impairment and environmental hazards fails to convey the complexity of potential contributory factors typical of most fall incidents.
Research limitations/implications
– Broadening our understanding of falls provides the potential to make recommendations for falls prevention practice across multiple levels, including the individual, social and organizational context.
Originality/value
– The paper evaluates the potential of video-based data in fall analysis and points to the development of a case study approach to analyzing fall incidents to capture the complex nature of contributory factors beyond research that focuses solely on intrinsic and extrinsic risk factors.

Abstract
Objective. To evaluate risk factors for falls and fragility fractures in healthy seniors.
Methods. Assessing 50 ambulatory community-dwelling volunteers ≥65 for demographics, BMI, bone mineral density (BMD) (DEXA), fracture risk (FRAX), balance (Biodex), fear of falling (Modified Falls Efficacy Scale (MFES)), and activity level (RAPA). One-year followup was done through phone interviews. Results. Most participants (17 males, 33 females; mean age 72.0±5.5 years) had normal BMD and were active with little to no fear of falling. Balance did not correlate with FRAX or fear of falling. Activity level did not correlate with FRAX, but the active group had less fear of falling. Most scored below age specific norms on balance testing. Fear of falling was not significantly different between genders but did correlate with FRAX, indicating that patients with higher fracture risk were also more afraid of falling. Individuals who fell after one year had increased fear of falling and decreased activity levels. Conclusions. Community-dwelling seniors with higher risk of future fractures were more afraid of falling. Although healthy and active, this cohort had poor balance compared to age matched norms. Further research on how to best assess fall risk and improve balance to prevent fractures is needed.

Abstract
In developed countries, falls in older people represent a rising problem. As effective prevention should start before the risk becomes evident, an early predictor is needed. Single stance instability would appear as a major risk factor. Aims of the study were to describe single stance stability, its sensory components, and their correlation with age and gender. A random sample of 597 older adults (319 men, 278 women) living at home, aged 65–84, was studied. Stability tests were performed with an electronic postural station. The single stance test showed the impairment of single stance stability in older individuals (75–84 yrs). The significant decline of stability in the older subjects may be explained by the impairment of proprioceptive control together with the decrease in compensatory visual stabilization and emergency responses. Younger subjects (65–74 yrs) exhibited better, but still inadequate, proprioceptive control with compensatory visual stabilization. Gender differences appeared in older subjects: women were significantly less stable than men. The measurement of the sensory components of single stance stability could aid in the early detection of a decay in antigravity movements many years before the risk of falling becomes evident. Adequate proprioceptive control could mitigate the effects of all other risks of falling.

Abstract
Background Falls in older people are a major public health issue, but the underlying causes are complex. We sought to evaluate the effectiveness of preventive home visits as a multifactorial, individualized strategy to reduce falls in community-dwelling older people. Methods Data were derived from a prospective randomized controlled trial with follow-up examination after 18 months. Two hundred and thirty participants (≥80 years of age) with functional impairment were randomized to intervention and control groups. The intervention group received up to three preventive home visits including risk assessment, home counseling intervention, and a booster session. The control group received no preventive home visits. Structured interviews at baseline and follow-up provided information concerning falls in both study groups. Random-effects Poisson regression evaluated the effect of preventive home visits on the number of falls controlling for covariates. Results Random-effects Poisson regression showed a significant increase in the number of falls between baseline and follow-up in the control group (incidence rate ratio 1.96) and a significant decrease in the intervention group (incidence rate ratio 0.63) controlling for age, sex, family status, level of care, and impairment in activities of daily living. Conclusion Our results indicate that a preventive home visiting program can be effective in reducing falls in community-dwelling older people.

Abstract
Falls have major consequences both at societal (health-care and economy) and individual (physical and psychological) levels. Questionnaires to assess fall risk are commonly used in the clinic, but their predictive value is limited. Objective methods, suitable for clinical application, are hence needed to obtain a quantitative assessment of individual fall risk. Falls in older adults often occur during walking and trunk position is known to play a critical role in balance control. Therefore, analysis of trunk kinematics during gait could present a viable approach to the development of such methods. In this study, nonlinear measures such as harmonic ratio (HR), index of harmonicity (IH), multiscale entropy (MSE) and recurrence quantification analysis (RQA) of trunk accelerations were calculated. These measures are not dependent on step detection, a potentially critical source of error. The aim of the present study was to investigate the association between the aforementioned measures and fall history in a large sample of subjects (42 fallers and 89 non - fallers) aged 50 or older. Univariate associations with fall history were found for MSE and RQA parameters in the AP direction; the best classification results were obtained for MSE with scale factor τ = 2 and for maximum length of diagonals in RQA (72.5% and 71% correct classifications, respectively). MSE and RQA were found to be positively associated with fall history and could hence represent useful tools in the identification of subjects for fall prevention programs.

Abstract
BACKGROUND Falls are one of the most frequently occurring adverse events that impact upon the recovery of older hospital inpatients. Falls can threaten both immediate and longer-term health and independence. There is need to identify cost-effective means for preventing falls in hospitals. Hospital-based falls prevention interventions tested in randomized trials have not yet been subjected to economic evaluation. METHODS Incremental cost-effectiveness analysis was undertaken from the health service provider perspective, over the period of hospitalization (time horizon) using the Australian Dollar (A$) at 2008 values. Analyses were based on data from a randomized trial among n = 1,206 acute and rehabilitation inpatients. Decision tree modeling with three-way sensitivity analyses were conducted using burden of disease estimates developed from trial data and previous research. The intervention was a multimedia patient education program provided with trained health professional follow-up shown to reduce falls among cognitively intact hospital patients. RESULTS The short-term cost to a health service of one cognitively intact patient being a faller could be as high as A$14,591 (2008). The education program cost A$526 (2008) to prevent one cognitively intact patient becoming a faller and A$294 (2008) to prevent one fall based on primary trial data. These estimates were unstable due to high variability in the hospital costs accrued by individual patients involved in the trial. There was a 52% probability the complete program was both more effective and less costly (from the health service perspective) than providing usual care alone. Decision tree modeling sensitivity analyses identified that when provided in real life contexts, the program would be both more effective in preventing falls among cognitively intact inpatients and cost saving where the proportion of these patients who would otherwise fall under usual care conditions is at least 4.0%. CONCLUSIONS This economic evaluation was designed to assist health care providers decide in what circumstances this intervention should be provided. If the proportion of cognitively intact patients falling on a ward under usual care conditions is 4% or greater, then provision of the complete program in addition to usual care will likely both prevent falls and reduce costs for a health service.

Abstract
OBJECTIVES To compare the cost-effectiveness of population screening for vitamin D insufficiency with that of universal vitamin D supplementation in community-dwelling older adults. DESIGN A Markov decision model simulating follow-up over a 36-month period. Published data were used to estimate values for the model, including costs (measured in 2011 U.S. dollars), utilities (measured in quality-adjusted life years (QALYs)), and probabilities. SETTING Decision analysis simulation from a societal perspective. PARTICIPANTS Hypothetical cohort of community-dwelling women and men aged 65 to 80. MEASUREMENTS Net monetary benefit (NMB) was calculated by subtracting the incremental cost of the strategy from the product of incremental QALYs and willingness-to-pay threshold. A higher NMB indicates greater cost-effectiveness. RESULTS In women aged 65 to 80, population screening was slightly more cost-effective than universal supplementation, with an incremental NMB of $224 compared with $189 (P < .001). Population screening in men was also more cost-effective than universal supplementation (incremental NMB $298 vs $260, P < .001). Results differed according to age group. In those aged 65, population screening had cost-effectiveness similar to that of universal supplementation in women ($59 vs $71) and men ($114 vs $120), whereas in those aged 80, population screening was substantially more cost-effective than universal supplementation in women ($563 vs $428) and men ($703 vs $571). CONCLUSION Population screening and universal supplementation for vitamin D insufficiency are cost-effective strategies in community-dwelling older women and men. In the oldest old, population screening may be more cost-effective than universal supplementation.

Abstract
UNLABELLED The purpose of this study was to analyze the cost-effectiveness of a multifactorial fall prevention program in nursing home residents. Given a willingness-to-pay (WTP) of 50,000 EUR per year free of femoral fracture, the probability that the intervention is cost-effective is 83%. INTRODUCTION Despite their increased risk of falls and fractures, nursing home residents have been neglected in economic evaluations of fall prevention programs so far. The purpose of this study was to analyze, for the first time, the cost-effectiveness of a multifactorial fall prevention program in nursing home residents. METHODS This study is part of a prospective, unblinded, cluster, nonrandomized, controlled study focusing on the transfer of an efficacious fall prevention program into a real-world setting. The analyzed subsample was derived from claims data and consisted of data on intervention (n=256, residents n=10,178) and control homes (n=893, residents n=22,974), representing all insurants of a sickness fund (AOK Bavaria, Germany) who were 65 years or older, residing in a nursing home on the 31st of March 2007 and had a level of care of ≥1 according to the classification of the statutory long-term care insurance. Time free of femoral fracture (ICD-10, S72) was used as measure of health effects. Femoral fracture-related costs and intervention costs were measured from a payer perspective. Multivariate regression models were applied. Sensitivity analyses were performed and cost-effectiveness acceptability curves computed. RESULTS Within the first year of the intervention, femoral fracture rate was significantly reduced, resulting in a nonsignificant incremental mean time of 1.41 days free of femoral fracture. Incremental mean total direct costs were 29 EUR per resident, which was not significant. The incremental cost-effectiveness ratio (ICER) was 7,481 EUR per year free of femoral fracture. The probability of an ICER<50,000 EUR per year free of femoral fracture was 83%. CONCLUSION Depending on the amount the decision-maker is willing to pay for the incremental effect, the fall prevention program might be cost-effective within the first year. Future studies should expand the range of costs and effects measured.

Abstract
Falls are one of the major causes of mortality and morbidity in older adults. Every year, an estimated 30-40% of patients over the age of 65 will fall at least once. Falls lead to moderate to severe injuries, fear of falling, loss of independence and death in a third of those patients. The direct costs alone from fall related injuries are a staggering 0.1% of all healthcare expenditures in the United States and up to 1.5% of healthcare costs in European countries. This figure does not include the indirect costs of loss of income both to the patient and caregiver, the intangible losses of mobility, confidence, and functional independence. Numerous studies have attempted to define the risk factors for falls in older adults. The present review provides a brief summary and update of the relevant literature, summarizing demographic and modifiable risk factors. The major risk factors identified are impaired balance and gait, polypharmacy, and history of previous falls. Other risk factors include advancing age, female gender, visual impairments, cognitive decline especially attention and executive dysfunction, and environmental factors. Recommendations for the clinician to manage falls in older patients are also summarized.

Abstract
UNLABELLED This controlled intervention study in hospitalized oldest old adults showed that a multifactorial fall-and-fracture risk assessment and management program, applied in a dedicated geriatric hospital unit, was effective in improving fall-related physical and functional performances and the level of independence in activities of daily living in high-risk patients. INTRODUCTION Hospitalization affords a major opportunity for interdisciplinary cooperation to manage fall-and-fracture risk factors in older adults. This study aimed at assessing the effects on physical performances and the level of independence in activities of daily living (ADL) of a multifactorial fall-and-fracture risk assessment and management program applied in a geriatric hospital setting. METHODS A controlled intervention study was conducted among 122 geriatric inpatients (mean ± SD age, 84 ± 7 years) admitted with a fall-related diagnosis. Among them, 92 were admitted to a dedicated unit and enrolled into a multifactorial intervention program, including intensive targeted exercise. Thirty patients who received standard usual care in a general geriatric unit formed the control group. Primary outcomes included gait and balance performances and the level of independence in ADL measured 12 ± 6 days apart. Secondary outcomes included length of stay, incidence of in-hospital falls, hospital readmission, and mortality rates. RESULTS Compared to the usual care group, the intervention group had significant improvements in Timed Up and Go (adjusted mean difference [AMD] = -3.7s; 95 % CI = -6.8 to -0.7; P = 0.017), Tinetti (AMD = -1.4; 95 % CI = -2.1 to -0.8; P < 0.001), and Functional Independence Measure (AMD = 6.5; 95 %CI = 0.7-12.3; P = 0.027) test performances, as well as in several gait parameters (P < 0.05). Furthermore, this program favorably impacted adverse outcomes including hospital readmission (hazard ratio = 0.3; 95 % CI = 0.1-0.9; P = 0.02). CONCLUSIONS A multifactorial fall-and-fracture risk-based intervention program, applied in a dedicated geriatric hospital unit, was effective and more beneficial than usual care in improving physical parameters related to the risk of fall and disability among high-risk oldest old patients.

Abstract
RATIONALE Little scrutiny has been applied to how 'cost per fall' values have been calculated and applied. This paper presents discourse discussing how the cost of fall statistic could potentially be misleading when applied to inpatient health or residential care settings and provides estimates of the cost of falls and cost of falls per person. METHOD Burden of disease was estimated using a decision tree approach. Data informing the decision tree were drawn from a retrospective audit of 545 falls in a residential care facility, a visual observation study of 46 residents from the same facility and a cohort study of 186 residents from nine different facilities in Australia. Acute care and transportation costs were extracted from the retrospective audit using incident reports and care note review. The distribution of falls per person and associations between falls, fractures and change in resident mobility were extracted from the cohort study. The association between resident mobility and the amount of time required to perform toileting, transfer and dressing activities was extracted from the visual observational study. RESULTS The minimum 'cost per fall' was estimated to be $AUD 841 and the maximum was $AUD 1024. The 'cost of falls per person' estimate was $AUD 1887 (2008 base year). CONCLUSIONS This cost per fall estimate was substantially lower than three previous internationally derived estimates possibly as a consequence of how fall data were collected and modelled in these studies. Cost of falls per person may be a preferable statistic for future use.

Abstract
Falls represent a heavy economic and clinical burden on society. The identification of individual chronic characteristics associated with falling is of fundamental importance for the clinicians; in particular, the stability of daily motor tasks is one of the main factors that the clinicians look for during assessment procedures. Various methods for the assessment of stability in human movement are present in literature, and methods coming from stability analysis of nonlinear dynamic systems applied to biomechanics recently showed promise. One of these techniques is orbital stability analysis via Floquet multipliers. This method allows to measure orbital stability of periodic nonlinear dynamic systems and it seems a promising approach for the definition of a reliable motor stability index, taking into account for the whole task cycle dynamics. Despite the premises, its use in the assessment of fall risk has been deemed controversial. The aim of this systematic review was therefore to provide a critical evaluation of the literature on the topic of applications of orbital stability analysis in biomechanics, with particular focus to methodologic aspects. Four electronic databases have been searched for articles relative to the topic; 23 articles were selected for review. Quality of the studies present in literature has been assessed with a customised quality assessment tool. Overall quality of the literature in the field was found to be high. The most critical aspect was found to be the lack of uniformity in the implementation of the analysis to biomechanical time series, particularly in the choice of state space and number of cycles to include in the analysis.

Abstract
BACKGROUND AND METHODS Fractures in elderly populations result from the combination of falls and osteoporosis. We report a systematic review of studies indexed in PubMed reporting annual rates of low-trauma falls and associated osteoporotic fractures among older community-dwelling people (age ≥ 50 years). An osteoporotic fracture was defined as either a fracture resulting from a low-impact fall in subjects with clinical osteoporosis, a fall resulting in an investigator-defined osteoporotic fracture, or a fall resulting in a low-trauma fracture. Rates are presented using descriptive statistics. Meta-analysis was conducted for statistically homogeneous data sets. RESULTS The median (range) annual fall prevalence rates (median proportion of people who experienced one or more falls during the past year) for cohorts of women and men (10 determinations), women alone (seven determinations), and men alone (four determinations) were, respectively, 0.334 (0.217-0.625), 0.460 (0.372-0.517), and 0.349 (0.284-0.526). In studies that reported fall prevalence rates for Western men and women separately (four determinations), the pooled risk ratio (95% confidence interval [CI]) for men versus women was 0.805 (95% CI 0.721-0.900). The ranges of fall prevalence rates in East Asian women (two studies) and East Asian men (two studies) were, respectively, 0.163-0.258 and 0.087-0.184. The risk ratio (95% CI) for fall prevalence in East Asian men versus women was 0.634 (0.479-0.838) in studies (two determinations) reporting results for East Asian men and women separately. In cohorts of Western women and men (five determinations), the pooled rate (95% CI) of low-impact falls resulting in fractures was 0.041 (0.031-0.054). The proportion of low-trauma fractures attributable to falls among the Western community-dwelling elderly was within the range of 0.860-0.950 for fractures at all sites or the hip (five determinations). A range of 0.716-0.924 of all fractures were osteoporotic (eight determinations). CONCLUSION Fall rates are higher in women than in men in Western community-dwelling populations and lower in East Asian populations. Extrapolated to the US population, the statistics imply that low-impact falls cause approximately 0.53 million osteoporotic fractures annually among the US community-dwelling elderly.

Abstract
The risk for fragility fracture represents a problem of enormous magnitude. It is estimated that only a small fraction of women with this risk take the benefit of preventive measures. The relationship between estrogen and bone mass is well known as they are the other factors related to the risk for fracture. There are precise diagnostic methods, including a tool to diagnose the risk for fracture. Yet there continues to be an under-diagnosis, with the unrecoverable delay in instituting preventive measures. Women under the age of 70 years, being much more numerous than those older, and having risk factors, are a group in which it is essential to avoid that first fragility fracture. Today it is usual not to differentiate between the treatment and the prevention of osteoporosis since the common aim is to prevent fragility fractures. Included in this are women with osteoporosis or with low bone mass and increased risk for fracture, for whom risk factors play a primary role. There is clearly controversy over the type of treatment and its duration, especially given the possible adverse effects of long-term use. This justifies the concept of sequential treatment, even more so in women under the age of 70, since they presumably will need treatment for many years. Bone metabolism is age-dependent. In postmenopausal women under 70 years of age, the increase in bone resorption is clearly predominant, related to a sharp drop in estrogens. Thus a logical treatment is the prevention of fragility fractures by hormone replacement therapy (HRT) and, in asymptomatic women, selective estradiol receptor modulators (SERMs). Afterwards, there is a period of greater resorption, albeit less intense but continuous, when one could utilise anti-resorptive treatments such as bisphosphonates or denosumab or a dual agent like strontium ranelate. Bone formation treatment, such as parathyroid hormone (PTH), in women under 70 years will be uncommon. That is because it should be used in cases where the formation is greatly diminished and there is a high risk for fracture, something found in much older women.

Abstract
BACKGROUND In late life, falls are associated with disability, increased health service utilization and mortality. Physical and psychological risk factors of falls include falls history, grip strength, sedative use, stroke, cognitive impairment, and mental ill-health. Less understood is the role of positive psychological well-being components. This study investigated the protective effect of vitality on the likelihood of falls in comparison to mental and physical health. METHODS Female participants were drawn from the Dynamic Analyses to Optimise Ageing (DYNOPTA) harmonization project. Participants (n = 11,340) were aged 55-95 years (Mean = 73.68; SD = 4.31) at baseline and observed on up to four occasions for up to 13 years (Mean = 5.30; SD = 2.53). RESULTS A series of random intercept logistic regression models consistently identified vitality's protective effects on falls as a stronger effect in the reduction of the likelihood of falls than the effect of mental health. Vitality is a significant predictor of falls likelihood even after adjusting for physical health, although the size of effect is substantially explained by its covariance with mental and physical heath. CONCLUSIONS Vitality has significant protective effects on the likelihood of falls. In comparison with mental health, vitality reported much stronger protective effects on the likelihood to fall in comparison with the risk associated with poor mental health in a large sample of older female adults. Both physical health and mental health account for much of the variance in vitality, but vitality still reports a protective effect on the likelihood of falls.

Abstract
AIMS This retrospective observational study examined the association between International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM)-coded outpatient hypoglycaemic events and fall-related fractures in Medicare-covered patients with type 2 diabetes. METHODS Data were derived from healthcare claims for individuals with employer-sponsored Medicare supplemental insurance. The study period consisted of two consecutive 1-year periods; the baseline period (1 April 2008 to 31 March 2009) and the evaluation period (1 April 2009 to 31 March 2010). Patients selected for study were at least 65 years of age with evidence of type 2 diabetes during the baseline period, as identified using a Healthcare Effectiveness Data and Information Set algorithm or by at least two prescription claims for oral antidiabetic drugs. The baseline period was used to collect information on the patients' demographics and clinical characteristics. The evaluation period was used to identify the presence of hypoglycaemic events and fall-related fractures. Logistic regression was employed to examine the association between hypoglycaemic events and fall-related fractures occurring during the evaluation period, adjusting for patients' demographics and clinical characteristics. RESULTS Of 361 210 included patients, 16 936 had hypoglycaemic events during the evaluation period. Patients with hypoglycaemic events had 70% higher regression-adjusted odds (hypoglycaemic events odds ratio = 1.70; 95% confidence interval = 1.58-1.83) of fall-related fractures than patients without hypoglycaemic events. Multiple sensitivity analyses also yielded results suggesting increased odds of fall-related fractures in patients with hypoglycaemic events. CONCLUSIONS ICD-9-CM-coded outpatient hypoglycaemic events were independently associated with an increased risk of fall-related fractures. Further studies of the relationship between hypoglycaemia and the risk of fall-related fractures are warranted.

Abstract
BACKGROUND Falls are a common mechanism of injury in the older population, putting an increasing demand on scarce healthcare resources. The objective of this study was to determine healthcare costs due to falls in the older population. METHODS An incidence-based cost model was used to estimate the annual healthcare costs and costs per case spent on fall-related injuries in patients ≥ 65 years, The Netherlands (2007-2009). Costs were subdivided by age, gender, nature of injury, and type of resource use. RESULTS In the period 2007-2009, each year 3% of all persons aged ≥ 65 years visited the Emergency Department due to a fall incident. Related medical costs were estimated at €675.4 million annually. Fractures led to 80% (€540 million) of the fall-related healthcare costs. The mean costs per fall were €9370, and were higher for women (€9990) than men (€7510) and increased with age (from €3900 at ages 65-69 years to €14,600 at ages ≥ 85 year). Persons ≥ 80 years accounted for 47% of all fall-related Emergency Department visits, and 66% of total costs. The costs of long-term care at home and in nursing homes showed the largest age-related increases and accounted together for 54% of the fall-related costs in older people. DISCUSSION Fall-related injuries are leading to a high healthcare consumption and related healthcare costs, which increases with age. Programmes to prevent falls and fractures should be further implemented in order to reduce costs due to falls in the older population and to avoid that healthcare systems become overburdened.

Abstract
Obesity prevention provides a major opportunity to improve population health. As health improvements usually require additional and scarce resources, novel health technologies (interventions) should be economically evaluated. In the prevention of obesity, health benefits may slowly accumulate over time and it can take many years before an intervention has reached full effectiveness. Decision-analytic simulation models (DAMs), which combine evidence from diverse sources, can be utilized to evaluate the long-term cost-effectiveness of such interventions. This literature review summarizes long-term economic findings (defined as ≥ 40 years) for 41 obesity prevention interventions, which had been evaluated in 18 cost-utility analyses, using nine different DAMs. Interventions were grouped according to their method of delivery, setting and risk factors targeted into behavioural (n=21), community (n=12) and environmental interventions (n=8). The majority of interventions offered good value for money, while seven were cost-saving. Ten interventions were not cost-effective (defined as >50,000 US dollar), however. Interventions that modified a target population's environment, i.e. fiscal and regulatory measures, reported the most favourable cost-effectiveness. Economic findings were accompanied by a large uncertainty though, which complicates judgments about the comparative cost-effectiveness of interventions.

Abstract
RÉSUMÉLes chutes représentent 40 pour cent des accidents d’hôpitaux et leurs conséquences vont de zéro à des blessures graves. Le but de cette étude a été d’estimer le coût moyen à l’hôpital de la durée du séjour (DS) associée aux chutes liées aux préjudices graves dans un hôpital de soins actifs. Nous avons utilisé les données de gestion des risques et des bases de données qui représentent les frais associés à une blessure grave après une chute à l’hôpital. On a comparé trente-sept patients blessés à 2,330 contrôles en utilisant le diagnostic le plus responsable médical, et par l’âge et par le sexe des patients. En utilisant les t-tests et la regréssion multivariée, on a comparé le coût et la DS. Les coûts moyens pour ceux qui se sont grièvement blessés en tombant, et pour les contrôles sans chutes, étaient DC 44,203 $ et DC 13,507 $ tandis ceux de la DS était, respectivement, 45 et 11 jours. Le coût des soins d’hospitalisation pour un patient qui a subi une chute résultante en blessures graves était 30,696 $ (95% IC : $25,158 – $36,781) supérieur au coût pour quelqu’un qui ne s’est pas tombé. Les gestionnaires d’hôpitaux jouent un rôle de premier plan en créant des programmes dans le réseau pour prévenir les chutes et réduire les coûts hospitaliers.

Abstract
UNLABELLED We prospectively collected data on elderly fallers to estimate the total cost of a fall requiring an Emergency Department presentation. Using data collected on 102 falls, we found the average cost per fall causing an Emergency Department presentation of $11,408. When hospitalization was required, the average cost per fall was $29,363. INTRODUCTION For elderly persons, falls are a major source of mortality, morbidity, and disability. Previous Canadian cost estimates of seniors' falls were based upon administrative data that has been shown to underestimate the incidence of falls. Our objective was to use a labor-intensive, direct observation patient-tracking method to accurately estimate the total cost of falls among seniors who presented to a major urban Emergency Department (ED) in Canada. METHODS We prospectively collected data from seniors (>70 years) presenting to the Vancouver General Hospital ED after a fall. We excluded individuals who where cognitively impaired or unable to read/write English. Data were collected on the care provided including physician assessments/consultations, radiology and laboratory tests, ED/hospital time, rehabilitation facility time, and in-hospital procedures. Unit costs of health resources were taken from a fully allocated hospital cost model. RESULTS Data were collected on 101 fall-related ED presentations. The most common diagnoses were fractures (n = 33) and lacerations (n = 11). The mean cost of a fall causing ED presentation was $11,408 (SD: $19,655). Thirty-eight fallers had injuries requiring hospital admission with an average total cost of $29,363 (SD: $22,661). Hip fractures cost $39,507 (SD: $17,932). Among the 62 individuals not admitted to the hospital, the average cost of their ED visit was $674 (SD: $429). CONCLUSIONS Among the growing population of Canadian seniors, falls have substantial costs. With the cost of a fall-related hospitalization approaching $30,000, there is an increased need for fall prevention programs.
