Sarcopenia as a risk factor for falls in elderly individuals: Results from the ilSIRENTE study

BACKGROUND & AIMS Sarcopenia has been indicated as a reliable marker of frailty and poor prognosis among the oldest individuals. We evaluated the relationship between sarcopenia and 2-year risk of falls in a population of persons aged 80 years or older. METHODS Data are from the baseline and follow-up evaluations of the Aging and Longevity Study in the Sirente Geographic Area (ilSIRENTE Study) (n=260). According to the European Working Group on Sarcopenia in Older People (EWGSOP), sarcopenia was diagnosed in presence of low muscle mass (mid-arm muscle circumference) plus either low muscle strength (hand grip) or low physical performance (4-m walking speed). The primary outcome measure was the incident falls during the follow-up period of 2 years. The relationship between sarcopenia and incident falls was estimated by deriving hazard ratios (HRs) from multiple logistic regression models considering the dependent variable of interest at least one fall during the follow-up period. RESULTS Sixty-six participants (25.4%) were identified as affected by sarcopenia. Eighteen out of 66 (27.3%) participants with sarcopenia and 19 out of 194 (9.8%) without sarcopenia reported incident falls during the two-year follow-up of the study (p<0.001). After adjusting for age, gender, cognitive impairment, ADL impairment, sensory impairments, BMI, depression, physical activity, cholesterol, stroke, diabetes, number of medications, and C-reactive protein, participants with sarcopenia had a higher risk of incident falls compared with non sarcopenic subjects (adjusted hazard ratio [HR], 3.23; 95% confidence interval [CI], 1.25-8.29). CONCLUSIONS The present study suggests that sarcopenia - assessed using the EWGSOP algorithm - is highly prevalent among elderly persons without gender differences (25%). Sarcopenic participants were over three times more likely to fall during a follow-up period of 2 years relative to non sarcopenic individuals, regardless of age, gender and other confounding factors.

Sarcopenia and mortality risk in frail older persons aged 80 years and older: results from ilSIRENTE study

BACKGROUND AND AIMS sarcopenia has been indicated as a reliable marker of frailty and poor prognosis among the oldest individuals. We evaluated the impact of sarcopenia on the risk of all-cause death in a population of frail older persons living in community. METHODS we analysed data from the Aging and Longevity Study, a prospective cohort study that collected data on all subjects aged 80 years and older residing in the Sirente geographic area (n = 364). The present analysis was conducted among those subjects who were between 80 and 85 years of age at the time of the baseline assessment (n = 197). The main outcome measure was all-cause mortality over 7-year follow-up. According to the European Working Group on Sarcopenia in Older People (EWGSOP) criteria, the diagnosis of sarcopenia required the documentation of low muscle mass and the documentation of either low muscle strength or low physical performance. Cox proportional regression models were used to estimate crude and adjusted hazard ratios and 95% confidence intervals of death by the presence of sarcopenia. RESULTS using the EWGSOP-suggested criteria, 43 subjects with sarcopenia (21.8%) were identified. During the 7-year follow-up, 29 (67.4%) participants died among subjects with sarcopenia compared with 63 subjects (41.2%) without sarcopenia (P < 0.001). After adjusting for potential confounders including age, gender, education, activities of daily living (ADL) impairment, body mass index, hypertension, congestive heart failure, chronic obstructive pulmonary disease, number of diseases, TNF-α, participants with sarcopenia had a higher risk of death for all causes compared with non-sarcopenic subjects (HR: 2.32, 95% CI: 1.01-5.43). CONCLUSIONS our results obtained from a representative sample of very old and frail subjects show that sarcopenia is associated with mortality, independently of age and other clinical and functional variables.

Prevalence and Risk Factors of Sarcopenia Among Nursing Home Older Residents

BACKGROUND AND AIMS Sarcopenia has been indicated as a reliable marker of frailty and poor prognosis among the oldest individuals. At present, there are no data on sarcopenia in nursing home population. We evaluated the prevalence of sarcopenia and its association with functional and clinical status in a population of elderly persons aged 70 years and older living in nursing homes. METHODS This study was conducted selecting all the participants (n = 122) living in the teaching nursing homes of Catholic University of Rome who were aged 70 years and older from August 1, 2010, to September 30, 2010. The European Working Group on Sarcopenia in Older People (EWGSOP) criteria were adopted. Accordingly, diagnosis of sarcopenia required the documentation of low muscle mass plus the documentation of either low muscle strength or low physical performance. RESULTS Forty residents (32.8%) were identified as affected by sarcopenia. The multivariate logistic regression analysis showed a high increase in risk of sarcopenia for male residents (odds ratio [OR] 13.39; 95% confidence interval [CI] 3.51-50.63) and for residents affected by cerebrovascular disease (OR 5.16; 95% CI 1.03-25.87) or osteoarthritis (OR 7.24; 95% CI 2.02-25.95). Residents who had a body mass index higher than 21 kg/m(2) had a lower risk to be sarcopenic (OR 0.76; 95% CI 0.64-0.90) relative to those with body mass index less than 21 kg/m(2). Similarly, sarcopenia was less likely to be present among participants involved in leisure physical activity for 1 hour or more per day (OR 0.40; 95% CI 0.12-0.98). CONCLUSIONS The present study suggests that among participants living in nursing homes, sarcopenia is highly prevalent and it is more represented among male residents (68%) than among female residents (21%). Our findings support the hypothesis that muscle mass is strongly associated with nutritional status and physical activity in nursing homes, too.

Polypharmacy in Nursing Home in Europe: Results From the SHELTER Study

BACKGROUND This study assesses prevalence and patients characteristics related to polypharmacy in a sample of nursing home residents. METHODS We conducted a cross-sectional analysis on 4,023 nursing home residents participating to the Services and Health for Elderly in Long TERm care (SHELTER) project, a study collecting information on residents admitted to 57 nursing home in 8 countries. Data were collected using the interRAI instrument for long-term care facilities. Polypharmacy status was categorized in 3 groups: non-polypharmacy (0-4 drugs), polypharmacy (5-9 drugs) and excessive polypharmacy (≥ 10 drugs). RESULTS Polypharmacy was observed in 2,000 (49.7%) residents and excessive polypharmacy in 979 (24.3%) residents. As compared with non-polypharmacy, excessive polypharmacy was directly associated not only with presence of chronic diseases but also with depression (odds ratio [OR] 1.81; 95% confidence interval [CI] 1.38-2.37), pain (OR 2.31; 95% CI 1.80-2.97), dyspnoea (OR 2.29; 95% CI 1.61-3.27), and gastrointestinal symptoms (OR 1.73; 95% CI 1.35-2.21). An inverse association with excessive polypharmacy was shown for age (OR for 10 years increment 0.85; 95% CI 0.74-0.96), activities of daily living disability (OR for assistance required vs independent 0.90; 95% CI 0.64-1.26; OR for dependent vs independent 0.59; 95% CI 0.40-0.86), and cognitive impairment (OR for mild or moderate vs intact 0.64; 95% CI 0.47-0.88; OR for severe vs intact 0.39; 95% CI 0.26-0.57). CONCLUSIONS Polypharmacy and excessive polypharmacy are common among nursing home residents in Europe. Determinants of polypharmacy status include not only comorbidity but also specific symptoms, age, functional, and cognitive status.

Assessment of nursing home residents in Europe: the Services and Health for Elderly in Long TERm care (SHELTER) study

BackgroundAims of the present study are the following: 1. to describe the rationale and methodology of the Services and Health for Elderly in Long TERm care (SHELTER) study, a project funded by the European Union, aimed at implementing the interRAI instrument for Long Term Care Facilities (interRAI LTCF) as a tool to assess and gather uniform information about nursing home (NH) residents across different health systems in European countries; 2. to present the results about the test-retest and inter-rater reliability of the interRAI LTCF instrument translated into the languages of participating countries; 3 to illustrate the characteristics of NH residents at study entry.MethodsA 12 months prospective cohort study was conducted in 57 NH in 7 EU countries (Czech Republic, England, Finland, France, Germany, Italy, The Netherlands) and 1 non EU country (Israel). Weighted kappa coefficients were used to evaluate the reliability of interRAI LTCF items.ResultsMean age of 4156 residents entering the study was 83.4 ± 9.4 years, 73% were female. ADL disability and cognitive impairment was observed in 81.3% and 68.0% of residents, respectively. Clinical complexity of residents was confirmed by a high prevalence of behavioral symptoms (27.5% of residents), falls (18.6%), pressure ulcers (10.4%), pain (36.0%) and urinary incontinence (73.5%). Overall, 197 of the 198 the items tested met or exceeded standard cut-offs for acceptable test-retest and inter-rater reliability after translation into the target languages.ConclusionThe interRAI LTCF appears to be a reliable instrument. It enables the creation of databases that can be used to govern the provision of long-term care across different health systems in Europe, to answer relevant research and policy questions and to compare characteristics of NH residents across countries, languages and cultures.

Midarm muscle circumference, physical performance and mortality: results from the aging and longevity study in the Sirente geographic area (ilSIRENTE study).

BACKGROUND & AIMS Sarcopenia has been indicated as a reliable marker of frailty and poor prognosis among the oldest individuals. We evaluated the relationship between midarm muscle circumference (MAMC) and physical performance, muscle strength, functional status and survival in persons aged 80 years or older. METHODS Data are from the baseline evaluation of the Aging and Longevity Study in the Sirente Geographic Area (ilSIRENTE Study) (n = 357). MAMC was calculated taking into account the mid upper arm circumference and the triceps skinfold thickness of the right arm. Physical performance was assessed using the physical performance battery score, which is based on three timed tests: 4-m walking speed test, the balance test and the chair stand test. Analyses of covariance were performed to evaluate the relationship between different MAMC levels and physical function. Cox proportional regression models were used to estimate crude and adjusted hazard ratios and 95% confidence intervals of death by MAMC levels. RESULTS After adjustment for potential confounders - which included age, gender, living alone, sensory impairments (hearing and vision), body mass index, albumin and cholesterol - physical performance and function (which were measured using the 4-m walking speed test, the Short Physical Performance Battery score, the hand grip strength), improved significantly as MAMC increased. Compared with those in the low MAMC tertile, subjects in the high MAMC tertile had a lower risk of death (adjusted hazard ratio (HR) 0.45; 95% Confidence Interval (CI) 0.23-0.87). CONCLUSIONS The present study suggests that among community-dwelling old-old subjects muscle mass may be positively related to functional performance and survival.

Disability, More than multimorbidity, was predictive of mortality among older persons aged 80 years and older.

OBJECTIVE In this study, we evaluate the impact of disability and multimorbidity on the risk of all-cause death in a population of frail older persons living in community. STUDY DESIGN AND SETTING We analyzed data from the Aging and Longevity Study in the Sirente geographic area, a prospective cohort study that collected data on all subjects aged 80 years and older (n=364). The main outcome measure was all-cause mortality over 4-year follow-up. RESULTS A total of 150 deaths occurred. Sixty-seven subjects (44.6%) died in the nondisabled group compared with 83 subjects (55.3%) in the disabled group (P<0.01). Thirty-nine subjects (31.7%) died among subjects without multimorbidity compared with 111 subjects (46.0%) with two or more diseases (P<0.01). When examining the combined effect of multimorbidity and disability, the effect of disability on the risk of death was higher than that of multimorbidity. After adjusting for potential confounders, relative to those without disability and multimorbidity, disabled subjects showed an increased risk of death when multimorbidity was associated (hazard ratio [HR]=3.91; 95% confidence interval [CI]=1.53-10.00) and in absence of multimorbidity (HR=2.36; 95% CI=0.63-8.83). CONCLUSION Our results show that disability exerts an important influence on mortality, independently of age and other clinical and functional variables.

Pain in European long-term care facilities: Cross-national study in Finland, Italy and the Netherlands

&NA; There have been very few and limited cross‐national comparisons concerning pain among residents of long‐term care facilities in Europe. The aim of the present cross‐sectional study has been to document the prevalence of pain, its frequency and severity as well as its correlates in three European countries: Finland (north), Italy (south) and the Netherlands (western central). Patients (aged 65 years or above) were assessed with the Minimum Data Set 2.0 (MDS).The final sample comprised 5761 patients from 64 facilities in Finland, 2295 patients from 8 facilities in the Netherlands and 1959 patients from 31 facilities in Italy. The prevalence of pain – defined as any type of pain – varied between 32% in Italy, 43% in the Netherlands and 57% in Finland. In nearly 50% of cases, pain was present daily; there were no significant differences in pain prevalence between patients with cancer diagnosis and those with non‐cancer diagnosis. Regardless of the different prevalence estimates, pain was moderate‐to‐severe in over 50% of cases in all the countries. In multivariate logistic regression models, clinical correlates of pain were substantially similar across countries: pain was positively correlated with more severe physical disability (ADL impairment), clinical depression and a diagnosis of osteoporosis. Pain was negatively correlated with a diagnosis of dementia and more severe degrees of cognitive deterioration. We conclude that pain is frequently encountered in long‐term care facilities in Europe and that, despite cultural and case‐mix differences, pain speaks one language.

All-cause mortality associated with atypical and conventional antipsychotics among nursing home residents with dementia: a retrospective cohort study

OBJECTIVE A recent meta-analysis has indicated that, in patients with dementia, the use of atypical antipsychotics is associated with an excess mortality. Later observational studies have suggested that conventional antipsychotics may pose an even greater risk of death. None of these studies could evaluate the risk associated with single antipsychotics nor could they provide any conclusive evidence concerning the risk among nursing home residents. We conducted a retrospective cohort study to compare the risk of death associated with atypical and conventional antipsychotics in a large population of nursing home residents with dementia. METHOD We identified 6,524 new users of atypical antipsychotics and 3,205 new users of conventional antipsychotics living in 1,581 Medicare- or Medicaid-certified nursing homes in 5 US states during the years 1998-2000. The outcome measure was all-cause mortality, which was determined during 6-months of follow-up. RESULTS After adjusting for potential confounders relative to users of atypicals, the rate of death was increased for users of conventional antipsychotics (hazard ratio [HR], 1.26; 95% CI, 1.13-1.42). Relative to risperidone, a higher rate of death was documented for haloperidol (HR, 1.31; 95% CI, 1.13-1.53), phenothiazines (HR, 1.17; 95% CI, 1.00-1.38) and other conventional medications (HR, 1.32; 95% CI, 0.99-1.80). No atypical antipsychotic was associated with a differential risk relative to risperidone. CONCLUSIONS Conventional antipsychotics are associated with a higher risk of all-cause mortality than atypical agents. It seems advisable that they are not used in substitution for atypical antipsychotics among nursing home residents with dementia even when short-term therapy is being prescribed.

Non malignant daily pain and risk of disability among older adults in home care in Europe.

Abstract Aim of the present observational study was to evaluate the association between daily pain and incident disability in elderly subjects living in the community. We used data from the AgeD in HOme Care (AD‐HOC) project, a 1 year longitudinal study enrolling subjects aged 65 or older receiving home care in 11 European countries. Daily pain was defined as any type of pain or discomfort in any part of the body manifested every day in the seven days before the baseline assessment. Disability performing activities of daily living (ADLs) was defined as the need of assistance in 1 or more of the following ADL: eating, dressing, transferring, mobility in bed, personal hygiene and toileting. Mean age of 1520 subjects participating the study was 82.1 (standard deviation 6.9) years, and 1178 (77.5%) were women and 695 (45.7%) reported daily pain at the baseline assessment. Overall, 123/825 participants (19.0%) with daily pain and 132/695 (14.9%) without daily pain reported incident disability during the 1 year follow up of the study. After adjustment for potential confounders, participants with daily pain had a significantly higher risk of developing disability, compared with other participants (hazard ratio 1.36; 95% CI: 1.05–1.78). The risk of disability increased with pain severity and with number of painful sites. In conclusion among old subjects living in the community, daily pain is associated with an increased risk of disability.
