Falls, Injuries Due to Falls, and the Risk of Admission to a Nursing Home

Abstract: Background Falls warrant investigation as a risk factor for nursing home admission because falls are common and are associated with functional disability and because they may be preventable. Methods We conducted a prospective study of a probability sample of 1103 people over 71 years of age who were living in the community. Data on demographic and medical characteristics, use of health care, and cognitive, functional, psychological, and social functioning were obtained at base line and one year later during assessments in the participants' homes. The primary outcome studied was the number of days from the initial assessment to a first long-term admission to a skilled-nursing facility during three years of follow-up. Patients were assigned to four categories during follow-up: those who had no falls, those who had one fall without serious injury, those who had two or more falls without serious injury, and those who had at least one fall causing serious injury. Results A total of 133 participants (12.1 perce...

Consequences of Driving Cessation Decreased Out-of-Home Activity Levels

Abstract: OBJECTIVES: Increasing age, socioeconomic factors, and declining function and health have been linked to driving cessation, but little is known about the consequences of stopping driving. This study was designed to test the hypothesis that driving cessation leads to a decline in out-of-home activity levels. METHODS: In 1989 a survey of driving practices was administered to surviving noninstitutionalized members of the New Haven Established Populations for Epidemiologic Studies of the Elderly (EPESE) cohort. Of 1,316 respondents, 502 were active drivers as of 1988, 92 had stopped driving between 1982 and 1987, and 722 never drove or stopped before 1982. Information on sociodemographic and health-related variables came from in-home EPESE interviews in 1982, 1985, and 1988, and from yearly phone interviews. Activity was measured at all three in-home interviews, and an activity measure was created based on self-reported participation in nine out-of-home activities. A repeated measures random-effects model was used to test the effect of driving cessation on activity while controlling for potential confounders. RESULTS: Driving cessation was strongly associated with decreased out-of-home activity levels (coefficient-1.081, standard error 0.264, p Language: en

Driving Cessation and Increased Depressive Symptoms: Prospective Evidence from the New Haven EPESE

Abstract: OBJECTIVES: The purpose of this study was to determine the association between driving cessation and depressive symptoms among older drivers. Previous efforts in this area have focused on the factors associated with cessation, not the consequences of having stopped. DESIGN: Cohort study SETTING: Urban community PARTICIPANTS: A driving survey was administered in 1989 to surviving noninstitutionalized members of the New Haven Established Populations for Epidemiologic Studies of the Elderly (EPESE) cohort. Of 1316 respondents, 502 were active drivers as of 1988, 92 had stopped driving between 1982 and 1987, and the remainder had either never driven or had stopped before 1982. MEASUREMENTS: Information about independent and dependent variables other than driving status came from the in-person EPESE interviews in 1982, 1985, and 1988, except for medical conditions, which were updated yearly. Depressive symptoms were assessed by the Centers for Epidemiologic Studies - Depression (CES-D) scale. Analyses focused on the changes in depressive symptoms before and after driving cessation. Repeated measures multivariable analysis accounted for the effect of cessation on the outcome adjusting for the potential confounding due to sociodemographic and health-related factors. RESULTS: Individuals who stopped driving exhibited substantial increases in depressive symptoms during the 6-year interval. Driving cessation was among the strongest predictors of increased depressive symptoms (Coefficient 2.464, SE 0.758, P = .001) even when adjusting for sociodemographic and health-related factors. CONCLUSIONS: Driving cessation was associated with an increase in depressive symptoms even when accounting for sociodemographic and health-related factors. These consequences need to be taken into account when advising older drivers and when developing alternative transportation strategies.

The effect of falls and fall injuries on functioning in community-dwelling older persons.

Abstract: BACKGROUND Several preventive strategies have proven effective at reducing the occurrence and rate of falling. It remains to be determined, however, whether, and to what extent, falls and/or fall injuries are independent determinants of adverse functional outcomes in older persons. METHODS A probability sample of 1,103 community-dwelling persons over age 71 years was followed for 3 years. The 957 cohort members (87%) who participated in at least one follow-up interview while residing in the community were included in this study. Outcome measures included one and three year change in basic and instrumental activities of daily living (BADLs-IADLs), social activities, and physical activities. Based on daily calendars and hospital surveillance, participants were placed into one of four levels of fall status: no falls, one fall without serious injury, at least two falls without serious injury, and one or more falls with serious injury. Hierarchical linear regression models, sequentially adding six domains of covariates, were constructed to examine fall status as a risk factor for change in function. RESULTS One noninjurious fall (beta = -.437; p < .01), at least two noninjurious falls (beta = -.877; p < .001); and at least one injurious fall (beta = -1.254; p < .001) were each associated with decline in BADL-IADL function over 3 years after adjusting for covariates (model R2 = .2617). Experiencing two or more noninjurious falls (beta = -.538; p < .05) was associated with decline in social activities (model R2 = .2779) while experiencing at least one injurious fall (beta = -.580; p < .01) was associated with decline in physical activity (model R2 = .4231). CONCLUSIONS Falls and fall injuries appear to be independent determinants of functional decline in community-dwelling older persons. Falling is a health condition meeting all criteria for prevention: high frequency, evidence of preventability, and high burden of morbidity.

The mortality of elder mistreatment.

Abstract: ContextAlthough elder mistreatment is suspected to be life threatening in some instances, little is known about the survival of elderly persons who have been mistreatedObjectiveTo estimate the independent contribution of reported elder abuse and neglect to all-cause mortality in an observational cohort of community-dwelling older adultsDesignProspective cohort study with at least 9 years of follow-upSetting and PatientsThe New Haven Established Population for Epidemiologic Studies in the Elderly cohort, which included 2812 community-dwelling adults who were older than 65 years in 1982, a subset of whom were referred to protective services for the elderlyMain Outcome MeasuresAll-cause mortality among (1) elderly persons for whom protective services were used for corroborated elder mistreatment (elder abuse, neglect, and/or exploitation), or (2) elderly persons for whom protective services were used for self-neglectResultsIn the first 9 years after cohort inception, 176 cohort members were seen by elderly protective services for verified allegations; 10 (57%) of these were for abuse, 30 (170%) for neglect, 8 (45%) for exploitation, and 128 (727%) for self-neglect At the end of a 13-year follow-up period from cohort inception, cohort members seen for elder mistreatment at any time during the follow-up had poorer survival (9%) than either those seen for self-neglect (17%) or other noninvestigated cohort members (40%) (P<001) In a pooled logistic regression that adjusted for demographic characteristics, chronic diseases, functional status, social networks, cognitive status, and depressive symptomatology, the risk of death remained elevated for cohort members experiencing either elder mistreatment (odds ratio, 31; 95% confidence interval, 14-67) or self-neglect (odds ratio, 17; 95% confidence interval, 12-25), when compared with other members of the cohortConclusionsReported and corroborated elder mistreatment and self-neglect are associated with shorter survival after adjusting for other factors associated with increased mortality in older adults

Interventions for preventing falls in older people living in the community

Abstract: As people get older, they may fall more often for a variety of reasons including problems with balance, poor vision, and dementia. Up to 30% may fall in a year. Although one in five falls may require medical attention, less than one in 10 results in a fracture. This review looked at the healthcare literature to establish which fall prevention interventions are effective for older people living in the community, and included 159 randomised controlled trials with 79,193 participants. Group and home-based exercise programmes, usually containing some balance and strength training exercises, effectively reduced falls, as did Tai Chi. Overall, exercise programmes aimed at reducing falls appear to reduce fractures. Multifactorial interventions assess an individual's risk of falling, and then carry out treatment or arrange referrals to reduce the identified risks. Overall, current evidence shows that this type of intervention reduces the number of falls in older people living in the community but not the number of people falling during follow-up. These are complex interventions, and their effectiveness may be dependent on factors yet to be determined. Interventions to improve home safety appear to be effective, especially in people at higher risk of falling and when carried out by occupational therapists. An anti-slip shoe device worn in icy conditions can also reduce falls. Taking vitamin D supplements does not appear to reduce falls in most community-dwelling older people, but may do so in those who have lower vitamin D levels in the blood before treatment. Some medications increase the risk of falling. Three trials in this review failed to reduce the number of falls by reviewing and adjusting medications. A fourth trial involving family physicians and their patients in medication review was effective in reducing falls. Gradual withdrawal of a particular type of drug for improving sleep, reducing anxiety, and treating depression (psychotropic medication) has been shown to reduce falls. Cataract surgery reduces falls in women having the operation on the first affected eye. Insertion of a pacemaker can reduce falls in people with frequent falls associated with carotid sinus hypersensitivity, a condition which causes sudden changes in heart rate and blood pressure. In people with disabling foot pain, the addition of footwear assessment, customised insoles, and foot and ankle exercises to regular podiatry reduced the number of falls but not the number of people falling. The evidence relating to the provision of educational materials alone for preventing falls is inconclusive.

2013 Alzheimer's disease facts and figures

Abstract: This report provides information to increase understanding of the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality rates, health expenditures and costs of care, and effect on caregivers and society in general. It also explores the roles and unique challenges of long‐distance caregivers, as well as interventions that target those challenges. An estimated 5.2 million Americans have AD. Approximately 200,000 people younger than 65 years with AD comprise the younger onset AD population; 5 million comprise the older onset AD population. Throughout the coming decades, the baby boom generation is projected to add about 10 million to the total number of people in the United States with AD. Today, someone in America develops AD every 68 seconds. By 2050, one new case of AD is expected to develop every 33 seconds, or nearly a million new cases per year, and the total estimated prevalence is expected to be 13.8 million. AD is the sixth leading cause of death in the United States and the fifth leading cause of death in Americans age 65 years or older. Between 2000 and 2010, the proportion of deaths resulting from heart disease, stroke, and prostate cancer decreased 16%, 23%, and 8%, respectively, whereas the proportion resulting from AD increased 68%. The number of deaths from AD as determined by official death certificates (83,494 in 2010) likely underrepresents the number of AD‐related deaths in the United States. A projected 450,000 older Americans with AD will die in 2013, and a large proportion will die as a result of complications of AD. In 2012, more than 15 million family members and other unpaid caregivers provided an estimated 17.5 billion hours of care to people with AD and other dementias, a contribution valued at more than $216 billion. Medicare payments for services to beneficiaries age 65 years and older with AD and other dementias are three times as great as payments for beneficiaries without these conditions, and Medicaid payments are 19 times as great. Total payments in 2013 for health care, long‐term care, and hospice services for people age 65 years and older with dementia are expected to be $203 billion (not including the contributions of unpaid caregivers). An estimated 2.3 million caregivers of people with AD and other dementias live at least 1 hour away from the care recipient. These “long‐distance caregivers” face unique challenges, including difficulty in assessing the care recipient's true health condition and needs, high rates of family disagreement regarding caregiving decisions, and high out‐of‐pocket expenses for costs related to caregiving. Out‐of‐pocket costs for long‐distance caregivers are almost twice as high as for local caregivers.
