Association of frailty with survival: a systematic literature review.

Frailty is a known risk factor for those aged 65 and over, and its prevalence increases with age. Definitions of frailty vary widely, and prevalence estimates are affected by the way frailty is defined. Systematic reviews have yet to examine the literature on the association between definitions of frailty and mortality. We examined the definitions and prevalence of frailty and its association with survival in older community-dwelling adults. We conducted a systematic review of observational population-based studies published in English. We calculated pooled prevalence of frailty with a random effects model. We identified 24 population-based studies that examined frailty in community-dwelling older adults. The pooled prevalence was 14% when frailty was defined as a phenotype exhibiting three or more of the following: weight loss, fatigue/exhaustion, weakness, low physical activity/slowness, and mobility impairment. The pooled prevalence was 24% when frailty was defined by accumulation of deficits indices that included up to 75 diseases and impairments. The prevalence of frailty increased with age and was greater in women and in African Americans. Frailty in older adults was associated with poor survival with a dose-responsive reduction in survival per increasing number of frailty criteria. Taking into account population prevalence and multivariate adjusted relative risks, we estimated that 3-5% of deaths among older adults could be delayed if frailty was prevented. Frailty is a prevalent and important geriatric syndrome associated with decreased survival. Geriatric assessment of frailty provides clinically important information about functional status and survival of older adults.

Psychometric Properties of the Activities-Specific Balance Confidence Scale and the Survey of Activities and Fear of Falling in Older Women

OBJECTIVES: To compare the psychometric properties of the Activities‐specific Balance Confidence Scale (ABC) and the Survey of Activities and Fear of Falling in the Elderly (SAFE).

Not just specific diseases: Systematic review of the association of geriatric syndromes with hospitalization or nursing home admission

To examine the association between geriatric syndromes with hospitalization or nursing home admission, we reviewed studies that examined hospitalization and nursing home admission in community-dwelling older adults with multiple morbidities, cognitive impairment, frailty, disability, sarcopenia, malnutrition, impaired homeostasis, and chronic inflammation. Studies published in English language were identified through MEDLINE (1990 through April 2010), Cochrane databases, the Centers for Disease Control and Prevention website and manual searches of reference lists from relevant publications. The study had to include general (non-disease specific) populations of adults aged 65 years or older. Using a standardized protocol, two investigators independently abstracted information on participant characteristics and adjusted measures of the association. Studies that controlled for the presence of specific diseases were further identified and analyzed. When the syndrome examined was similar from different studies, we computed the pooled risk estimates using a random-effects model. We assessed the strength of evidence following the recommended guidelines. We identified 47 eligible articles from 6 countries. Multiple morbidity, frailty, and disabilities were associated with hospitalization and nursing home admission (moderate evidence). Cognitive impairment was associated with hospitalization (low evidence) and nursing home admission (moderate evidence). Among these studies, 20 articles controlled for specific diseases. Limited evidence suggested that these geriatric syndromes are associated with hospitalization and institutionalization after controlling for the presence of specific diseases. We conclude that geriatric syndromes are associated with risk of hospitalization or nursing home admission. Efforts to prevent hospitalization or nursing home admission should target strategies to prevent and manage these syndromes.

OBJECTIVES: To test the effectiveness of an education and counseling intervention on reducing environmental hazards in the homes of older women.

Older people’s perspectives on fall risk and fall prevention programs: a literature review

Despite evidence supporting fall prevention methods, fall-related injury and death rates continue to rise. Understanding older peoples views on fall risk and prevention will help nurses and other health professionals in the design of fall prevention strategies that will broaden their scope, reach and adoption. This literature review synthesised 19 qualitative and quantitative studies examining older peoples perspectives about fall risk and prevention using a social-ecological framework. Three themes emerged about fall risk; fearing vulnerability, maintaining autonomy and independence and interpreting risk. Four themes emerged about fall prevention programs: influence of participant and program characteristics, need for personal relevance and preference, maintaining autonomy and independence and increased support for and access to programs. Implications for practice include individual, interpersonal, organizational and community level considerations for improving fall prevention efforts.

State of the science: Conservative interventions for urinary incontinence in frail community-dwelling older adults

This systematic literature review aimed to identify conservative interventions for reducing urinary incontinence (UI) in non-institutionalized frail older adults. Randomized and quasi-experimental studies published in English reporting outcomes on UI frequency, severity, or quality of life were included and rated for quality. Studies reporting improvements over 50% in UI outcomes were considered clinically significant. Seven studies with 683 participants (75% female) were eligible. Multicomponent behavioral interventions including pelvic floor muscle exercises and bladder training had the strongest evidence for reducing UI. The evidence supporting comprehensive geriatric assessment with multicomponent behavioral interventions, pattern urge response training, and toilet skills was limited. There is insufficient evidence to derive firm conclusions regarding the use of conservative interventions. Clinical trials are needed on a variety of interventions to guide practice on UI prevention and management in frail community-dwelling older adults.

Factors associated with toileting disability in older adults without dementia living in residential care facilities

Background:Older adults without dementia living in residential care facilities with toileting disability have increased care costs and dependency. Understanding associated factors could guide prevention and management strategies. Objective:The aim of this study was to identify the prevalence of and factors associated with toileting disability in this population. Methods:This was a cross-sectional analysis of the 2010 National Survey of Residential Care Facilities. A subsample (n = 2,395) of adults aged 65 years or older, without dementia, and with the potential to implement behavioral interventions was examined. Associated factors were classified according to the disablement process as pathologies, impairments, functional limitations, coexisting disabilities, and intraindividual and extraindividual factors. Logistic regression models accounting for the stratified two-stage probability sampling design were used to identify factors associated with toileting disability. Results:Residents were mostly White women, aged 85 years and older. Prevalence of toileting disability was 15%. Associated factors included reporting fair or poor health; living in a facility with four or less residents; living in a for-profit facility; having bowel incontinence, urinary incontinence, more physical impairments, and visual and hearing impairments; and needing assistance with bathing, dressing, and transferring. Discussion:Multicomponent and multidisciplinary prevention and management efforts should be designed for residents without dementia. Future studies testing the efficacy of prevention efforts are needed and should include treatments for incontinence; physical activity programs targeting impairments with walking, standing, sitting, stooping, reaching, and grasping; and therapy to improve dressing, bathing, and transferring skills.

Change in balance confidence and its associations with increasing disability in older community-dwelling women at risk for falling

Objectives: To describe change in balance confidence, and to identify associated factors and disabling consequences. Method: Secondary analysis of 2 years of data collected from 272 older women enrolled in a randomized clinical trial of fall prevention. Balance confidence and disability measures were assessed at baseline, after the 12 week intervention, and at 1 and 2 years follow-up. Associated factors were measured at baseline. Results: Balance confidence varied at baseline and decreased 5% over 2 years, but no variables predicted this decline. Baseline balance confidence was associated with poor physical function and mental health. Decreasing balance confidence was associated with increasing impairments in balance and hip flexion strength, increasing functional limitations in mobility and chair rises, reduced physical activity levels, increased activity restrictions, and decreasing social networks. Discussion: Decreasing balance confidence plays an important role in disablement. More research is needed to identify predictors of decreasing balance confidence.

Restorative Care's Effect on Activities of Daily Living Dependency in Long-stay Nursing Home Residents.

PURPOSE OF THE STUDY (a) Identify the prevalence of nursing homes providing Medicare supported restorative care programs and of long stay participants, (b) compare characteristics between restorative care participants and nonparticipants, and (c) assess restorative cares effect on change in activities of daily living (ADL) dependency. DESIGN AND METHODS Longitudinal analysis of Minimum Data Set assessments linked to the 2004 National Nursing Home Survey using a sample of 7,735 residents, age ≥ 65 years living in 1,097 nursing homes for at least 6 months. Receipt of any restorative care was used as a time varying predictor to estimate change in ADL dependency over 18 months using linear mixed models. RESULTS The sample was 75% female, 89% non-Hispanic White, with a mean age of 85±8, and average length of stay of 3.2±3.4 years. Most nursing homes had restorative care programs (67%), but less than one-third of long-stay residents participated. After controlling for resident and nursing home characteristics, the predicted mean ADL dependency score (range 0-28) at baseline was 18 for restorative care participants and 14 for nonparticipants. Over 18 months, ADL dependency increased 1 point for both participants and nonparticipants (p = .12). IMPLICATIONS A minority of long-stay residents participated in Medicare supported restorative care programs despite their availability and potential benefits. Even though participants had greater vulnerability for deterioration in physical, mental, and functional health than nonparticipants, both groups had similar rates of ADL decline. Future research is needed to determine if providing restorative care to less dependent long-stay residents is effective.
