Prevention of Hip Fractures in Long-Term Care: Relevance of Community-Derived Data

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2010
Richard G. Crilly MD
Osteoporosis and falling are two major contributing factors to fractures in older persons; the relevant contribution of these may vary according to age, setting, and frailty. The purpose of this review was to examine the existing evidence on osteoporosis treatments to determine whether participants in clinical trials include or resemble the older and frailer adult population living in long-term care (LTC). The trials (N=50) used to support major Canadian guidelines for osteoporosis treatment were reviewed because these are used to recommend treatment for all older adults, and several more-recent studies were added. Trials conducted specifically with participants living in LTC were also reviewed (N=6). The majority of studies (96.0%) on osteoporosis treatments were conducted with community-dwelling participants, with many excluding participants resembling the LTC population. Mean ages ranged from 52 to 84, although for the majority of studies, the mean age was younger than 70. Similarly, 80.0% of studies conducted in LTC included only residents who were ambulatory, mobile, able to transfer independently, or not permanently bedridden. Mean ages in these studies ranged from 83 to 85. These findings suggest that frail older adults, particularly the oldest and frailest adults in LTC, are neglected in clinical trials of osteoporosis fracture prevention. There is little evidence to support the application of community-based guidelines to the LTC population, and studies directly involving this population are needed. The role of age, frailty, and the mechanics of falls in hip fracture are discussed. [source]


Validation and Comparison of Two Frailty Indexes: The MOBILIZE Boston Study

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2009
Dan K. Kiely MPH
OBJECTIVES: To validate two established frailty indexes and compare their ability to predict adverse outcomes in a diverse, elderly, community-dwelling sample of men and women. DESIGN: Prospective observational study. SETTING: A diverse defined geographic area of Boston. PARTICIPANTS: Seven hundred sixty-five community-dwelling participants in the Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly Boston Study. MEASUREMENTS: Two published frailty indexes, recurrent falls, disability, overnight hospitalization, emergency department (ED) visits, chronic medical conditions, self-reported health, physical function, cognitive ability (including executive function), and depression. One index was developed from the Study of Osteoporotic Fractures (SOF) and the other from the Cardiovascular Health Study (CHS). RESULTS: The SOF frailty index classified 77.1% as robust, 18.7% as prefrail, and 4.2% as frail. The CHS frailty index classified 51.2% as robust, 38.8% as prefrail, and 10.0% as frail. Both frailty indexes (SOF; CHS) were similar in their ability to predict key geriatric outcomes such as recurrent falls (hazard ratio (HR)frail=2.2, 95% confidence interval (CI)=1.2,4.0; HRfrail=1.9, 95% CI=1.2,3.1), overnight hospitalization (odds ratio (OR)frail=3.5, 95% CI=1.5,8.0; ORfrail=4.4, 95% CI=2.4,8.2), ED visits (ORfrail=3.5, 95% CI=1.4,8.8; ORfrail=3.1, 95% CI=1.6,5.9), and disability (ORfrail=5.4, 95% CI=2.3,12.3; ORfrail=7.7, 95% CI=4.0,14.7), as well as chronic medical conditions, physical function, cognitive ability, and depression. CONCLUSION: Two established frailty indexes were validated using an independent elderly sample of diverse men and women; both indexes were good at distinguishing geriatric conditions and predicting recurrent falls, overnight hospitalization, and ED visits according to level of frailty. Although both indexes are good measures of frailty, the simpler SOF index may be easier and more practical in a clinical setting. [source]


Metabolic Markers of Cobalamin Deficiency and Cognitive Function in Normal Older Adults

Angeles A. Garcia MD, FRCPC
Objectives: To investigate the relationship between metabolic markers of cobalamin deficiency and cognitive function in normal older adults. Design: Cross-sectional study. Setting: Queen's University and St. Mary's of the Lake Hospital, Kingston, Ontario, Canada. Participants: Two hundred eighty-one cognitively normal, community-dwelling participants aged 65 and older. Measurements: Serum cobalamin, red blood cell folate, methylcitric acid, homocysteine, and methylmalonic acid were determined. Cognitive instruments included the California Verbal Learning Test, Mattis Dementia Rating Scale, and the Stroop Neuropsychological Screening Inventory (Stroop). Results: Serum levels of methylcitric acid had a significant negative correlation with recall, learning, and discriminability (factor 1) of the California Verbal Learning Test after adjusting for age and sex (,=,0.138, P=.019). Subjects with elevated methylcitric acid had significantly lower scores (factor 1) than subjects with normal methylcitric acid (P<.01). Bivariate analysis showed significant correlations between levels of homocysteine and the Stroop score and between cobalamin, methylmalonic acid, and homocysteine and some scores of the California Verbal Learning Test, but these relationships did not remain significant after multivariate analysis. Subjects with high homocysteine (tHcy) had lower Stroop scores than subjects with normal tHcy (P<.05). No biochemical parameters were associated with the Mattis Dementia Rating Scale scores. Conclusion: This study indicates that, in normal elderly subjects, some cognitive scores are related to serum methylcitric acid and possibly homocysteine. [source]


Is Depressive Symptomatology Associated with Worse Oral Functioning and Well-being Among Older Adults?

JOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 1 2002
Nancy R. Kressin PhD;
Abstract Objectives: Although depression negatively affects individuals' physical functioning and well-being, its association with oral functioning and well-being has not been examined previously. The objective of this study was to examine the association between depressive symptomatology and oral quality of life. Methods: We utilized data from two samples of older adults: community-dwelling participants who used community primary care physicians in Los Angeles (n=7,653) and individuals who sought ambulatory care through four Department of Veterans Affairs facilities in the Boston metropolitan area (n=212). Depressive symptomatology was measured with the CES-D scale; Oral Quality of Life was measured with the Geriatric Oral Health Assessment Instrument and the Oral Health-related Quality of Life measure. We conducted hierarchical regression analyses to examine the effects of depression on oral quality of life, controlling for self-reported oral health, age, education, income, and marital status. Results: Individuals with more depressive symptoms reported worse oral quality of life, controlling for socio demographic factors and self-reported oral health. This finding persisted across multiple samples and both sexes, and using two measures of oral quality of life. Conclusion: These findings further emphasize the importance of treating depression among older adults, and suggest that both dentists and physicians have a role in recognizing and referring patients for such treatment.

Disagreement between subjective and actigraphic measures of sleep duration in a population-based study of elderly persons,

Summary Sleep duration is an important concept in epidemiological studies. It characterizes a night's sleep or a person's sleep pattern, and is associated with numerous health outcomes. In most large studies, sleep duration is assessed with questionnaires or sleep diaries. As an alternative, actigraphy may be used, as it objectively measures sleep parameters and is feasible in large studies. However, actigraphy and sleep diaries may not measure exactly the same phenomenon. Our study aims to determine disagreement between actigraphic and diary estimates of sleep duration, and to investigate possible determinants of this disagreement. This investigation was embedded in the population-based Rotterdam Study. The study population consisted of 969 community-dwelling participants aged 57,97 years. Participants wore an actigraph and kept a sleep diary for, on average, six consecutive nights. Both measures were used to determine total sleep time (TST). In 34% of the participants, the estimated TST in the sleep diaries deviated more than 1 h from actigraphically measured TST. The level of disagreement between diary and actigraphic measures decreased with subjective and actigraphic measures of sleep quality, and increased with male gender, poor cognitive function and functional disability. Actigraphically measured poor sleep was often accompanied by longer subjective estimates of TST, whereas subjectively poor sleepers tended to report shorter TST in their diaries than was measured with actigraphy. We recommend, whenever possible, to use multiple measures of sleep duration, to perform analyses with both, and to examine the consistency of the results over assessment methods. [source]
