ABSTRACT: Objective
To ensure accurate data capture for a fall study through a system of daily contact with participants.Methods
Fifty-eight adults older than 60 years of age and living independently in the community in Canberra, Australia, were recruited for a prospective fall study. We adopted a system of daily contact with study participants for at least 12 months, either by email or by text, asking whether they had suffered a fall in the previous 24 h. At the final testing session, we asked participants whether they had experienced a fall during the previous twelve months.Results
We found no evidence that the daily reporting regime led to excess participant attrition. Only three participants withdrew over the course of the study, and the burden of responding was not cited as a factor in any of these cases. Of the 55 participants who completed the full twelve-month study period, 38 (69%) experienced at least one fall. We also identified inconsistencies between recall of falls occurring during the last twelve months of the study and the contemporaneously recorded data.Conclusions
Previous studies have found that increasing the reporting demands on fall study participants will lead to higher attrition. This study demonstrates that it is possible to maintain participant engagement and minimise attrition with appropriate design of reporting procedures. We confirm existing evidence regarding the unreliability of retrospective recall of falls. The study highlights the importance of comprehensive and accurate data capture and points to the possibility of under-reporting of fall incidence.

Project description:ObjectivesThis study aimed to determine the incidence of falls and risk factors associated with falling in discharged older adults.MethodsA prospective study was conducted on older adults who had been issued a discharge order in a Class A tertiary hospital in Chongqing, China, from May 2019 to August 2020. The risk of falling, depression, frailty, and daily activities were evaluated at discharge using the mandarin version of the fall risk self-assessment scale, Patient Health Questionnaire-9 (PHQ-9), FRAIL scale, and Barthel Index, respectively. The cumulative incidence function estimated the cumulative incidence of falls in older adults after discharge. And the risk factors of falls were explored using the sub-distribution hazard function in the competing risk model.ResultsIn a total of 1,077 participants, the total cumulative incidence of falls at 1, 6 and 12 months after discharge was 4.45%, 9.03%, and 10.80%, respectively. The cumulative incidence of falls in older adults with depression (26.19%, 49.93%, and 58.53%, respectively) and those with physical frailty (21.59%, 41.67%, and 48.73%, respectively) was much higher than that in those without depression and physical frailty (P < 0.05). Depression, physical frailty, Barthel Index, length of hospital stay, re-hospitalization, being cared for by others, and the self-assessed risk of falling were directly associated with falls.ConclusionsThe incidence of falls among older adults discharged from the hospital has a cumulative effect with the lengthening of the discharge time. It is affected by several factors, especially depression and frailty. We should develop targeted intervention strategies to reduce falls for this group.

Project description:BackgroundFalls contribute to impairments in activities of daily living (ADLs), resulting in significant declines in the quality of life, safety, and functioning of older adults. Understanding the magnitude and duration of the effect of falls on ADLs, as well as identifying the characteristics of older adults more likely to have post-fall ADL impairment is critical to inform fall prevention and post-fall intervention. The purpose of this study is to 1) Quantify the association between falls and post-fall ADL impairment and 2) Model trajectories of ADL impairment pre- and post-fall to estimate the long-term impact of falls and identify characteristics of older adults most likely to have impairment.MethodStudy participants were from the Ginkgo Evaluation of Memory Study, a randomized controlled trial in older adults (age 75+) in the United States. Self-reported incident falls and ADL scores were ascertained every 6 months over a 7-year study period. We used Cox proportional hazards analyses (n = 2091) to quantify the association between falls and ADL impairment and latent class trajectory modeling (n = 748) to visualize trajectories of ADL impairment pre-and post-fall.ResultsFalls reported in the previous 6 months were associated with impairment in ADLs (HR: 1.42; 95% CI 1.32, 1.52) in fully adjusted models. Based on trajectory modeling (n = 748), 19% (n = 139) of participants had increased, persistent ADL impairment after falling. Participants who were female, lived in a neighborhood with higher deprivation, or experienced polypharmacy were more likely to have ADL impairment post-fall.ConclusionsFalls are associated with increased ADL impairment, and this impairment can persist over time. It is crucial that all older adults, and particularly those at higher risk of post-fall ADL impairment have access to comprehensive fall risk assessment and evidence-based fall prevention interventions, to help mitigate the negative impacts on ADL function.

Project description:BackgroundPhysical activity is linked to many positive health outcomes, stimulating the development of exercise programs. However, many falls occur while walking and so promoting activity might paradoxically increase fall rates, causing injuries, and worse quality of life. The relationship between activity exposure and fall rates remains unclear. We investigated the relationship between walking activity (exposure to risk) and fall rates before and after an exercise program (V-TIME).MethodsOne hundred and nine older fallers, 38 fallers with mild cognitive impairment (MCI), and 128 fallers with Parkinson's disease (PD) were randomly assigned to one of two active interventions: treadmill training only or treadmill training combined with a virtual reality component. Participants were tested before and after the interventions. Free-living walking activity was characterized by volume, pattern, and variability of ambulatory bouts using an accelerometer positioned on the lower back for 1 week. To evaluate that relationship between fall risk and activity, a normalized index was determined expressing fall rates relative to activity exposure (FRA index), with higher scores indicating a higher risk of falls per steps taken.ResultsAt baseline, the FRA index was higher for fallers with PD compared to those with MCI and older fallers. Walking activity did not change after the intervention for the groups but the FRA index decreased significantly for all groups (p ≤ .035).ConclusionsThis work showed that V-TIME interventions reduced falls risk without concurrent change in walking activity. We recommend using the FRA index in future fall prevention studies to better understand the nature of intervention programs.

Project description:Age and age-related diseases have been suggested to decrease entropy of human gait kinematics, which is thought to make older adults more susceptible to falls. In this study we introduce a new entropy measure, called phase-dependent generalized multiscale entropy (PGME), and test whether this measure improves fall-risk prediction in community-dwelling older adults. PGME can assess phase-dependent changes in the stability of gait dynamics that result from kinematic changes in events such as heel strike and toe-off. PGME was assessed for trunk acceleration of 30 s walking epochs in a re-analysis of 1 week of daily-life activity data from the FARAO study, originally described by van Schooten et al. (2016). The re-analyzed data set contained inertial sensor data from 52 single- and 46 multiple-time prospective fallers in a 6 months follow-up period, and an equal number of non-falling controls matched by age, weight, height, gender, and the use of walking aids. The predictive ability of PGME for falls was assessed using a partial least squares regression. PGME had a superior predictive ability of falls among single-time prospective fallers when compared to the other gait features. The single-time fallers had a higher PGME (p < 0.0001) of their trunk acceleration at 60% of their step cycle when compared with non-fallers. No significant differences were found between PGME of multiple-time fallers and non-fallers, but PGME was found to improve the prediction model of multiple-time fallers when combined with other gait features. These findings suggest that taking into account phase-dependent changes in the stability of the gait dynamics has additional value for predicting falls in older people, especially for single-time prospective fallers.

Project description:With aging, bone density is reduced, increasing the risk of suffering osteoporosis and fractures. Increasing physical activity (PA) may have preventive effects. However, until now, no studies have considered movement behaviors with compositional data or its association to bone mass and structure measured by peripheral computed tomography (pQCT). Thus, the aim of our study was to investigate these associations and to describe movement behavior distribution in older adults with previous falls and fractures and other related risk parameters, taking into account many nutritional and metabolic confounders. In the current study, 70 participants above 65 years old (51 females) from the city of Zaragoza were evaluated for the EXERNET-Elder 3.0 project. Bone mass and structure were assessed with pQCT, and PA patterns were objectively measured by accelerometry. Prevalence of fear of falling, risk of falling, and history of falls and fractures were asked through the questionnaire. Analyses were performed using a compositional data approach. Whole-movement distribution patterns were associated with cortical thickness. In regard to other movement behaviors, moderate-to-vigorous PA (MVPA) showed positive association with cortical thickness and total true bone mineral density (BMD) at 38% (all p < 0.05). In addition, less light PA (LPA) and MVPA were observed in those participants with previous fractures and fear of falling, whereas those at risk of falling and those with previous falls showed higher levels of PA. Our results showed positive associations between higher levels of MVPA and volumetric bone. The different movement patterns observed in the groups with a history of having suffered falls or fractures and other risk outcomes suggest that different exercise interventions should be designed in these populations in order to improve bone and prevent the risk of osteoporosis and subsequent fractures.

Project description:OBJECTIVE:To examine the prevalence of falls, factors associated with falls and the relationship between falls and survival in older adults with multiple myeloma. METHODS:In an analysis of the Surveillance, Epidemiology and End Results (SEER)-Medicare Health Outcomes Survey (MHOS)-linked database, we examined 405 older adults with multiple myeloma (MM) and 513 matched non-cancer controls. The primary outcome was self-reported within the past 12 months. Age, race, gender, symptoms, and comorbidities were self-reported in the MHOS. Survival was calculated from SEER data. RESULTS:Of the patients with MM, 171 were within 1 year of diagnosis (cohort 1) and 234 were ?1 year postdiagnosis (cohort 2). Patients in cohorts 1 and 2 were more likely to have fallen than controls (26% and 33% vs 23%, P = .012). On multivariate analysis, among patients with myeloma (combined cohorts 1 and 2), factors associated with falls included self-report of fatigue (aOR 2.52 [95% CI 1.34-4.93]), depression (aOR 1.90 [95% CI 1.14-3.18]), or poorer general health (aOR 1.86 [95% CI 1.05-3.36]). Falls were not associated with survival. CONCLUSIONS:Older adults with MM have a greater prevalence of falls than matched controls. Self-reported fatigue, depression, and poorer general health are associated with greater odds of falls.

Project description:IntroductionFalls are the second leading reason for incidental or unexpected deaths worldwide. Many older adults who fall, regardless of whether they are injured or not, tend to experience fear of fall and this can lead to decreased participation in activities of daily living (ADLs). Subsequent falls lead to weakness, a decline in physical functioning, increased chances of falling and a negative impact on the instrumental ADLs. Here, we present our scoping review protocol to appraise the literature to describe and explain the home-modification interventions used by occupational therapists to address falls and participation in ADLs among community-dwelling older adults. We are aiming to review the available home-modification intervention protocols, facilitators and barriers to such interventions, and the experiences of occupational therapists and clients after receiving these interventions.Methods and analysisThis scoping review protocol follows existing guidelines for scoping reviews with a particular attention on Arksey and O'Malley (2005) and Colquhoun et al (2014). We will include the following databases: Scopus, Web of Science, PubMed, ProQuest, Cumulative Index to Nursing and Allied Health Literature and Google Scholar. We plan to conduct the literature search from August 16, 2020 to September 15, 2020. Two reviewers will independently screen eligible studies for inclusion. We will extract the bibliographic data, study design, details of the intervention provided, outcomes and experiences of occupational therapists and clients, and further organise them for better understanding.Ethics and disseminationAs secondary data analysis, this scoping review does not require ethics approval. Results will summarise and disseminate the existing literature related to home-modification interventions provided by occupational therapists addressing falls and participation in ADLs among community-dwelling older adults. We plan to disseminate the results through peer-reviewed journals and conferences, targeting occupational therapists, other rehabilitation workers, researchers and policy makers.

Project description:BACKGROUND: Falls have enormous impact in older adults. Yet, there is insufficient evidence regarding the effectiveness of preventive interventions in this setting. The objectives were to measure the frequency of falls and associated factors among older people living institutions. METHODS: Data were obtained from a survey on a probabilistic sample of residents aged ?65 years, drawn in 1998-99 from institutions of Madrid (Spain). Residents, their caregivers, and facility physicians were interviewed. Fall rates were computed based on the number of physician-reported falls in the preceding 30 days. Adjusted rate ratios were computed using negative binomial regression models, including age, sex, cognitive status, functional dependence, number of diseases, and polypharmacy. RESULTS: The final sample comprised 733 residents. The fall rate was 2.4 falls per person-year (95% confidence interval [CI], 2.04-2.82). The strongest risk factor was number of diseases, with an adjusted rate ratio (RR) of 1.32 (95% CI, 1.17-1.50) for each additional diagnosis. Other variables associated with falls were: urinary incontinence (RR = 2.56 [95% CI, 1.32-4.94]); antidepressant use (RR = 2.32 [95% CI, 1.22-4.40]); arrhythmias (RR = 2.00 [95% CI, 1.05-3.81]); and polypharmacy (RR = 1.07 [95% CI, 0.95-1.21], for each additional medication). The attributable fraction for number of diseases (with reference to those with ? 1 condition) was 84% (95% CI, 45-95%). CONCLUSIONS: Number of diseases was the main risk factor for falls in this population of institutionalized older adults. Other variables associated with falls, probably more amenable to preventive action, were urinary incontinence, antidepressants, arrhythmias, and polypharmacy.

Project description:BackgroundVisually impaired older adults have a greater risk of falling, making them particularly susceptible to fall-related health consequences and restricted physical activity. Unclear however, is the relationship between having falls and longitudinal changes in daily patterns of objectively measured physical activity in older adults with visual impairments.MethodsWe created a three-year prospective cohort study (Falls in Glaucoma Study) of older adults with primary or suspected glaucoma at the Johns Hopkins Wilmer Eye Institute from 2013 to 2015. Cumulative incidence of falls was determined through self-reported fall calendars over 12 months. Participants were then classified into one of three groups: multiple fallers (≥2 falls), single fallers (1 fall), and non-fallers (0). Daily physical activity was measured over 1 week using a waist-bound accelerometer during baseline and three-year follow-ups. Activity fragmentation was defined as the reciprocal of the mean activity bout length, with higher fragmentation reflecting shorter, more fractured bouts of continuous activity. Multivariate linear mixed-effects models were used to assess three-year longitudinal changes in: 1) activity fragmentation, and 2) accumulation of activity across six three-hour intervals from 5 AM to 11 PM.FindingsIn adjusted models accounting for visual field damage and other factors, multiple fallers demonstrated greater annual declines (per year) in daily active bouts (-1.79 bouts/day, 95% confidence interval [CI]: -3.35, -0.22), daily active minutes (-17.15 min/day, 95% CI: -26.35, -7.94), and increased fragmentation (1%, 95% CI: 0, 2%) over the three-year follow-up period as compared to non-fallers; no such changes were seen when comparing single fallers and non-fallers. In time-of-day analyses, multiple fallers experienced greater annual declines in average hourly steps over all periods of the day, though the rate of decline was only significant between 5 PM and 8 PM (-27.07 steps/hour, 95% CI: -51.15, -2.99) compared to non-fallers.InterpretationIn an older population with visual impairment, multiple falls over 12 months were associated with more transient and fragmented activity over a subsequent three-year period, and activity declines during evening hours, compared to non-fallers. These findings suggest that multiple fallers with visual impairment may be at high risk for a decline in physical capacity and endurance, warranting clinical interventions.FundingThe research was supported in part by National Institutes of Health Grant EY022976.

Project description:ObjectivesTo investigate time trends in incidence of activity of daily living (ADL) disability of Chinese older adults and to explore factors potentially contributing to trends.DesignPopulation-based prospective study using a multistage, randomized, cluster sampling process.SettingNine provinces of China.ParticipantsThree consecutive cohorts of people aged 60 and older from the China Health and Nutrition Survey: cohort 1993-2000 (n = 831), cohort 1997-2004 (n = 1,091), cohort 2000-2006 (n = 1,152).MeasurementsDisability in ADLs was defined as inability to perform at least one of five self-care activities (transferring, dressing, toileting, bathing, feeding). Data were analyzed using Cox and generalized estimating equation models.ResultsThe incidence (per 1,000 person-years) of ADL disability decreased significantly from 35.3 in 1993-2000 and 28.9 in 1997-2004 to 24.3 in 2000-2006 in Chinese older adults (Ptrend < .001). The incidence of ADL disability decreased significantly in men and women, in young-old adults (aged 60-74), and in those living in rural areas (all Ptrend ≤ .02) after controlling for multiple potential influential factors. Of the five ADL items, decline in incidence of disability was significant in transferring (Ptrend < .001) and bathing (Ptrend = .002) and marginally significant in toileting (Ptrend = .06) but stable in dressing (Ptrend = .38) and feeding (Ptrend = .26).ConclusionThe incidence of ADL disability decreased from 1993 to 2006 in older adults in China, especially in transferring and bathing, independent of sociodemographic, lifestyle, and chronic health conditions.
