Background

Depression increases disability and health care utilization in older patients with chronic obstructive pulmonary disease (COPD).

Objectives

To determine contribution of depressive symptoms to the incidence of moderate-severe and severe acute exacerbations of COPD (AECOPD) over 3 years.

Design

We analyzed data collected from a prospective cohort of patients with COPD (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints; ECLIPSE).

Setting

Multicentered outpatient.

Participants

A total of 2059 patients with COPD with complete data (63.7% men, mean age 63.4 + 7.1 years).

Measurements

Depression was assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Moderate-severe AECOPDs were collected; a subset of very severe AECOPD was defined as requiring hospital admission.

Results

A total of 540 (26%) patients with COPD reported high depressive symptoms (CES-D ≥16). High depressive symptoms at baseline related to an increased risk of moderate-severe and severe AECOPD during the follow-up (odds ratio [OR] 1.18; 95% confidence interval [CI] 1.07–1.30; for moderate-severe and OR 1.36; 95% CI 1.09–1.69 for severe events risk of hospitalizations) independent of key covariates of an AECOPD history before recruitment in the study, history of gastroesophageal reflux, baseline severity of airflow limitation, and white blood cell count that were also associated with an increased risk of moderate to severe exacerbations (all P < .001).

Conclusion

Presence of high depressive symptoms at baseline were associated with subsequent moderate-severe exacerbations and hospital admissions in patients with COPD over 3 years, independent of a history of exacerbations and other demographic and clinical factors. Targeted personalized medicine that focuses both on AECOPD risk and depression may be a step forward to improving prognosis of patients with COPD.  相似文献

Introduction

The burden of chronic obstructive pulmonary disease (COPD) in post-acute/long-term care (PA/LTC) settings is high, and many patients do not receive guideline-recommended care.

Methods

An interprofessional expert panel of PA/LTC professionals convened to discuss the unmet medical needs in patients with COPD in PA/LTC settings, and to make recommendations for the assessment of COPD patients to individualize the selection of maintenance treatment.

Results

Unmet needs observed in patients with COPD are described in addition to new tools for assessing individual patient abilities and appropriate device selection for maintenance treatment.

Conclusion

COPD management in PA/LTC settings needs to be reevaluated and updated to help reduce exacerbations, hospitalizations, and readmissions.  相似文献

Background

Anxiety and dyspnea, 2 major symptoms in patients with chronic obstructive pulmonary disease (COPD), are associated with high morbidity and mortality. Thus, critically evaluating and synthesizing the existing literature employing pulmonary rehabilitation (PR) and other behavioral therapies in the treatment of anxiety and dyspnea in patients with COPD may help clinicians determine the most efficacious potential treatments. We aim to examine the efficacy of PR and behavioral therapy [eg, cognitive behavioral therapy (CBT) and counseling] and other adjunct modalities used in patients with COPD.

Methods

We extracted relevant studies searching the published literature using an electronic database CINAHL, Medline, PubMed, Science Direct, and the Web of Science was conducted (spanning January 1, 2006 to November 15, 2016). Studies were included if they conducted PR and behavioral therapy (CBT, self-management, yoga) to treat anxiety and/or dyspnea in patients with COPD with or without randomized controlled trial.

Results

The 47 studies selected included 4595 participants (PR = 3756 and behavioral therapy = 839), ranging in age from 58 to 75 years. The total number of participants receiving a treatment was 3928, and 667 participants served in control groups. In the majority of studies, PR and CBT are effective in the treatment of anxiety and dyspnea in the short term, but the long-term benefit is limited. In addition, self-management, yoga therapy, and CBT plus PR were beneficial.

Conclusions

PR and CBT reduced both anxiety and dyspnea symptoms in patients with COPD in the short term. However, maintenance programs and the long-term benefits of PR and CBT remain inconclusive. Generally, the studies were relatively small and uncontrolled. Thus, prospective and randomized controlled trials with larger sample sizes are needed.  相似文献

Background

Comorbid depression is highly prevalent in geriatric patients and associated with functional loss, frequent hospital re-admissions, and a higher mortality rate. Cognitive behavioral psychotherapy (CBT) has shown to be effective in older depressive patients living in the community. To date, CBT has not been applied to older patients with acute physical illness and comorbid depression.

Objectives

To evaluate the effectiveness of CBT in depressed geriatric patients, hospitalized for acute somatic illness.

Design

Randomized controlled trial with waiting list control group.

Setting

Postdischarge intervention in a geriatric day clinic; follow-up evaluations at the patients’ homes.

Participants

A total of 155 randomized patients, hospitalized for acute somatic illness, aged 82 ± 6 years and suffering from depression [Hospital Anxiety and Depression Scale (HADS) scores >7]. Exclusion criteria were dementia, delirium, and terminal state of medical illness.

Intervention

Fifteen, weekly group sessions based on a CBT manual. Commencement of psychotherapy immediately after discharge in the intervention group and a 4-month waiting list interval with usual care in the control group.

Measurements

HADS depression total score after 4 months. Secondary endpoints were functional, cognitive, psychosocial and physical status, resource utilization, caregiver burden, and amount of contact with physician.

Results

The intervention group improved significantly in depression scores (HADS baseline 18.8; after 4 months 11.4), whereas the control group deteriorated (HADS baseline 18.1; after 4 months 21.6). Significant improvement in the intervention group, but not in the control group, was observed for most secondary outcome parameters such as the Barthel and Karnofsky indexes. Intervention effects were less pronounced in patients with cognitive impairment or acute fractures.

Conclusions

CBT is feasible and highly effective in geriatric patients. The benefits extend beyond effective recovery and include improvement in physical and functional parameters. Early diagnosis, good access to psychotherapy, and early intervention could improve care for depressive older patients.

Background

Cognitive impairment is common in people living with chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF); however, accurate estimates of prevalence are lacking. To date, there are no meta-analyses that have specifically investigated prevalence of mild cognitive impairment (MCI) in this particular population. Our aim was to undertake a systematic review and apply meta-analytic methods to estimate the prevalence of MCI and any cognitive impairment (ACI) in people with COPD and CHF.

Methods

We identified relevant studies for COPD and CHF by searching the published literature from inception to February 2016 using the MEDLINE and Web of Science databases. Studies were included if they documented the prevalence of MCI and/or cognitive impairment for COPD and CHF patients without dementia.

Results

Seventeen studies including people with CHF (n = 29,456) and 14 studies including people with COPD (n = 23,116) were included. The pooled mean age for COPD was 66.3 years and for CHF, 75.6 years. The pooled prevalence of MCI in the COPD was 25% (95% CI: 23%, 42%) and ACI, 32% (95% CI: 18%, 38%). Correspondingly, the pooled prevalence of MCI in those with CHF was 32% (95% CI: 22%, 43%) and ACI, 31% (95% CI: 23%, 40%).

Conclusions

One in 4 people with COPD and 1 in 3 people with CHF had MCI, respectively. The overall prevalence of ACI for COPD was 32% and for CHF, 31%. Future work should consider ways of detecting, managing, or improving cognitive function and other cognition-related outcomes in this group of people.  相似文献

Objectives

Higher or lower blood pressure may relate to cognitive impairment, whereas the relationship between blood pressure and cognitive impairment among the elderly is not well-studied. The study objective was to determine whether blood pressure is associated with cognitive impairment in the elderly, and, if so, to accurately describe the association.

Design

Cross-sectional data from the sixth wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) conducted in 2011.

Setting

Community-based setting in longevity areas in China.

Participants

A total of 7144 Chinese elderly aged 65 years and older were included in the sample.

Measures

Systolic blood pressures (SBP) and diastolic blood pressures (DBP) were measured, pulse pressure (PP) was calculated as (SBP) ? (DBP) and mean arterial pressures (MAP) was calculated as 1/3(SBP) + 2/3(DBP). Cognitive function was assessed via a validated Mini-Mental State Examination (MMSE).

Results

Based on the results of generalized additive models (GAMs), U-shaped associations were identified between cognitive impairment and SBP, DBP, PP, and MAP. The cutpoints at which risk for cognitive impairment (MMSE <24) was minimized were determined by quadratic models as 141 mm Hg, 85 mm Hg, 62 mm Hg, and 103 mm Hg, respectively. In the logistic models, U-shaped associations remained for SBP, DBP, and MAP but not PP. Below the identified cutpoints, each 1-mm Hg decrease in blood pressure corresponded to 0.7%, 1.1%, and 1.1% greater risk in the risk of cognitive impairment, respectively. Above the cutpoints, each 1-mm Hg increase in blood pressure corresponded to 1.2%, 1.8%, and 2.1% greater risk of cognitive impairment for SBP, DBP, and MAP, respectively.

Conclusion

A U-shaped association between blood pressure and cognitive function in an elderly Chinese population was found. Recognition of these instances is important in identifying the high-risk population for cognitive impairment and to individualize blood pressure management for cognitive impairment prevention.  相似文献

Objectives

Cognitive frailty, a condition describing the simultaneous presence of physical frailty and mild cognitive impairment, has been recently defined by an international consensus group. We estimated the predictive role of a “reversible” cognitive frailty model on incident dementia, its subtypes, and all-cause mortality in nondemented older individuals. We verified if vascular risk factors or depressive symptoms could modify this predictive role.

Design

Longitudinal population-based study with 3.5- and 7-year of median follow-up.

Setting

Eight Italian municipalities included in the Italian Longitudinal Study on Aging.

Participants

In 2150 older individuals from the Italian Longitudinal Study on Aging, we operationalized reversible cognitive frailty with the presence of physical frailty and pre-mild cognitive impairment subjective cognitive decline, diagnosed with a self-report measure based on item 14 of the Geriatric Depression Scale.

Measurements

Incidence of dementia, its subtypes, and all-cause mortality.

Results

Over a 3.5-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia [hazard ratio (HR) 2.30, 95% confidence interval (CI) 1.02–5.18], particularly vascular dementia (VaD), and all-cause mortality (HR 1.74, 95% CI 1.07–2.83). Over a 7-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia (HR 2.12, 95% CI 1.12–4.03), particularly VaD, and all-cause mortality (HR 1.39, 95% CI 1.03–2.00). Vascular risk factors and depressive symptoms did not have any effect modifier on the relationship between reversible cognitive frailty and incident dementia and all-cause mortality.

Conclusions

A model of reversible cognitive frailty was a short- and long-term predictor of all-cause mortality and overall dementia, particularly VaD. The absence of vascular risk factors and depressive symptoms did not modify the predictive role of reversible cognitive frailty on these outcomes.  相似文献

Objectives

Falls are highly prevalent in individuals with cognitive decline. The complex relationship between falls and cognitive decline (including both subtype and severity of dementia) and the influence of gait disorders have not been studied. This study aimed to examine the association between the subtype (Alzheimer disease [AD] versus non-AD) and the severity (from preclinical to moderate dementia) of cognitive impairment and falls, and to establish an association between falls and gait parameters during the course of dementia.

Design

Multicenter cross-sectional study.

Setting

“Gait, cOgnitiOn & Decline” (GOOD) initiative.

Participants

A total of 2496 older adults (76.6 ± 7.6 years; 55.0% women) were included in this study (1161 cognitively healthy individuals [CHI], 529 patients with mild cognitive impairment [MCI], 456 patients with mild dementia, and 350 with moderate dementia) from 7 countries.

Measurements

Falls history was collected retrospectively at baseline in each study. Gait speed and stride time variability were recorded at usual walking pace with the GAITRite system.

Results

The prevalence of individuals who fall was 50% in AD and 64% in non-AD; whereas it was 25% in CHIs. Only mild and moderate non-AD dementia were associated with an increased risk for falls in comparison with CHI. Higher stride time variability was associated with falls in older adults without dementia (CHI and each MCI subgroup) and mild non-AD dementia, whereas lower gait speed was associated with falls in all participant groups, except in mild AD dementia. When gait speed was adjusted for, higher stride time variability was associated with falls only in CHIs (odds ratio 1.14; P = .012), but not in MCI or in patients with dementia.

Conclusions

These findings suggest that non-AD, but not AD dementia, is associated with increased falls in comparison with CHIs. The association between gait parameters and falls also differs across cognitive status, suggesting different mechanisms leading to falls in older individuals with dementia in comparison with CHIs who fall.  相似文献

Objectives

To evaluate the prevalence of cognitive impairment (CI), including mild CI and dementia, in elderly patients with syncope and unexplained falls. In this population, we compared the use of the Mini-Mental State Examination (MMSE) with a cognitive screening test that assesses executive dysfunction typical of subcortical (vascular) CI, that is, the Montreal Cognitive Assessment (MoCA).

Design

Observational cohort study.

Setting

Outpatient fall and syncope clinic.

Participants

Consecutive patients aged ≥65 years with syncope and unexplained falls without loss of consciousness.

Measurements

Baseline characteristics, functional status, MMSE, MoCA, and magnetic resonance imaging scans of the brain. Main outcome: prevalence of CI, comparing the MMSE with the MoCA. CI was defined as an MMSE/MoCA score <26. Secondary outcomes: MMSE/MoCA overall and subdomain scores, Fazekas and medial temporal lobe atrophy scores.

Results

We included 200 patients, mean age 79.5 (standard deviation 6.6) years (Syncope Group: n = 101; Fall Group: n = 99). Prevalence of CI was 16.8% (MMSE) versus 60.4% (MoCA) in the Syncope Group (P < .001) and 16.8% (MMSE) versus 56.6% (MoCA) in the Fall Group (P < .001). Prevalence of CI did not differ between the Syncope Group and Fall Group with either method. Executive dysfunction was present in both groups.

Conclusion

CI is as common in elderly patients with syncope as it is in patients with unexplained falls, with an overall prevalence of 58%. The MMSE fails as a screening instrument for CI in these patients, because it does not assess executive function. Therefore, we recommend the MoCA for cognitive screening in older patients with syncope and unexplained falls.  相似文献

Objectives

This scoping study is the first step of a multiphase, international project aimed at designing a homecare robot that can provide functional support, track physical and psychological well-being, and deliver therapeutic intervention specifically for individuals with mild cognitive impairment.

Design

Observational requirements gathering study.

Participants and settings

Semistructured interviews were conducted with 3 participant groups: (1) individuals with memory challenges, mild cognitive impairment (MCI), or mild dementia (patients; n = 9); (2) carers of those with MCI or dementia (carers; n = 8); and (3) those with expertise in MCI or dementia research, clinical care, or management (experts; n = 16). Interviews took place at the university, at dementia care facilities or other workplaces, at participant's homes, or via skype (experts only).

Measurements

Semistructured interviews were conducted, transcribed, and reviewed.

Results

Several key themes were identified within the 4 topics of: (1) daily challenges, (2) safety and security, (3) monitoring health and well-being, and (4) therapeutic intervention.

Conclusions

A homecare robot could provide both practical and therapeutic benefit for the mildly cognitively impaired with 2 broad programs providing routine and reassurance; and tracking health and well-being. The next phase of the project aims to program homecare robots with scenarios developed from these results, integrate components from project partners, and then test the feasibility, utility, and acceptability of the homecare robot.  相似文献

Objectives

To examine the association between long-term adherence to the Dietary Approaches to Stop Hypertension (DASH) diet with cognitive function and decline in older American women.

Design

Prospective cohort study.

Setting

The Nurses' Health Study, a cohort of registered nurses residing in 11 US states.

Participants

A total of 16,144 women from the Nurses' Health Study, aged ≥70 years, who underwent cognitive testing a total of 4 times by telephone from 1995 to 2001 (baseline), with multiple dietary assessments between 1984 and the first cognitive examination. DASH adherence for each individual was based on scoring of intakes of 9 nutrient or food components.

Measurements

Long-term DASH adherence was calculated as the average DASH adherence score from up to 5 repeated measures of diet. Primary outcomes were cognitive function calculated as the average scores of the 4 repeated measures, as well as cognitive change of the Telephone Interview for Cognitive Status score and composite scores of global cognition and verbal memory.

Results

Greater adherence to long-term DASH score was associated with better average cognitive function, irrespective of apolipoprotein E ε4 allele status [multivariable-adjusted differences in mean z-scores between extreme DASH quintiles = 0.04 (95% confidence interval, CI 0.01–0.07), P trend = .009 for global cognition; 0.04 (95% CI 0.01–0.07), P trend = .002 for verbal memory and 0.16 (95% CI 0.03–0.29), and P trend = .03 for Telephone Interview for Cognitive Status, P interaction >0.24]. These differences were equivalent to being 1 year younger in age. Adherence to the DASH score was not associated with change in cognitive function over 6 years.

Conclusions

Our findings in the largest cohort on dietary patterns and cognitive function to date indicate that long-term adherence to the DASH diet is important to maintain cognitive function at older ages.  相似文献

Background

Although the older population is increasing worldwide, there is a marked deficit in the number of persons trained in geriatrics. It is now recognized that early detection and treatment of geriatric syndromes (frailty, sarcopenia, anorexia of aging, and cognitive decline) will delay or avert the development of disability.

Objectives

To identify simple screening programs available for primary health professionals to identify geriatric syndromes.

Data sources

PubMed for the last 5 years and study authors.

Results

A number of screening programs for early detection of geriatric syndromes have been developed for use by primary care health providers, for example, EasyCare, Gérontopôle Frailty Screening Tool, the Rapid Geriatric Assessment, the Kihon Checklist, and others.

Limitations

This is an evolving area with limited information on the outcomes of intervention and possible harms.

Conclusion

Validated screening programs exist but more work is required to determine their utility in improving outcomes of older persons.  相似文献

Objectives

Use of exercise technologies has benefits for community-dwelling older adults in terms of improved gait and balance. But research on the feasibility of use of exercise technologies in various geriatric health care settings is lacking. Hence, the current study examined the feasibility of implementing an exercise technology intended to augment rehabilitation in patients receiving post-acute care (PAC) in a skilled nursing facility (SNF). We focused on 3 indicators of feasibility: extent of usage (including predictors of more intense use), patients' acceptability of the technology, and limited efficacy.

Design

Cross-sectional study with data from patients' electronic medical records (EMR), exercise technology portal, and patient interviews.

Setting

SNF.

Participants

A sample of post-acute patients (n = 237).

Measurements

Sociodemographic and health-related variables, time spent using the technology, and 8 items of the Physical Activity Enjoyment Scale (PACES).

Results

Average time spent using the technology varied greatly (range, 1–460 minutes). A regression analysis showed that patients who had a longer length of stay (β = .01, P < .05) and were younger (β = ?0.01, P < .05) spent significantly more time using the technology. Acceptability of technology was high among patients. Finally, patients who used the technology had lower 30-day rehospitalization rates.

Conclusion

Exercise technology is feasible to use in supporting rehabilitation in patients receiving PAC in a SNF and seems to have beneficial effects.  相似文献

Objectives

We aimed to (1) study factors that determine the use of invasive procedures in the management of acute myocardial infarction (AMI) in patients with dementia and (2) determine whether the use of invasive procedures was associated with their better survival.

Design

Cohort study based on patients registered in the Swedish Dementia Registry (SveDem), 2007–2012. Median follow-up time was 228 days.

Setting

Patients diagnosed with dementia in specialist memory clinics and primary care units in Sweden.

Participants

A total of 525 patients with dementia who suffered AMI (mean age 89 years, 54% women).

Measurements

Information on AMI and use of invasive procedures (coronary angiography and percutaneous coronary intervention) was obtained from Swedish national health registers. Binary logistic regression was applied to study associations of patients’ characteristics with the use of invasive procedures; odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Survival was analyzed with Kaplan-Meier curves; log-rank test was used to compare survival of patients who received an invasive procedure versus those who did not receive it. Cox regression was applied to study association of the invasive procedures with all-cause mortality; hazard ratios (HRs) with 95% CIs were calculated.

Results

One hundred ten patients (21%) with dementia received an invasive procedure in the management of AMI. After multivariate adjustment, lower age and higher global cognitive status were associated with the use of invasive procedures. The invasively managed patients survived longer (P = .001). The use of invasive procedures was associated with a lower risk of all-cause mortality, adjusting for type of AMI and dementia disorder, age, gender, registration unit, history of AMI and comorbidity score (HR 0.35, 95% CI 0.21–0.59), or total number of drugs (HR 0.34, 95% CI 0.20–0.58).

Conclusion

Age and cognitive status determine the use of invasive procedures in patients with dementia. This study suggests that the invasive management of AMI has a benefit for survival of patients with dementia.  相似文献

Objectives

Pulmonary rehabilitation enhances health status and mood status in patients with chronic obstructive pulmonary disease (COPD). The aim was to determine the responsiveness of St. George's Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT), COPD Clinical Questionnaire (CCQ), and Hospital Anxiety and Depression Scale (HADS) to pulmonary rehabilitation in patients with COPD, and estimate minimum clinically important differences (MCIDs) for CAT, CCQ, and HADS.

Design

A prospective analysis. MCIDs were estimated with anchor-based (anchor: SGRQ) and distribution-based methods. Newly estimated MCIDs were compared to known MCID estimates from a systematic literature search.

Setting

Newly estimated MCIDs were calculated in patients treated in pulmonary rehabilitation.

Participants

A subsample of 419 individuals with COPD (55.4% male, mean age 64.3 ± 8.8 years) were included from the Chance study.

Measurements

Health status was measured with SGRQ, CAT, and CCQ, before and after pulmonary rehabilitation. Mood status was assessed using HADS.

Results

419 patients with COPD (forced expiratory volume in the first second 37.3% ± 12.1% predicted) completed pulmonary rehabilitation. SGRQ (?9.1 ± 14.0 points), CAT (?3.0 ± 6.8 points), CCQ (?0.6 ± 0.9 points), HADS-Anxiety (?1.7 ± 3.7 points), and HADS-Depression (?2.1 ± 3.7 points) improved significantly. New MCIDs were estimated for CAT (range: ?3.8 to ?1.0 points), CCQ (range: ?0.8 to ?0.2 points), HADS-Anxiety (range: ?2.0 to ?1.1 points), and HADS-Depression (range: ?1.8 to ?1.4 points).

Conclusions

The SGRQ, CAT, CCQ, and HADS are responsive to pulmonary rehabilitation in patients with COPD. We propose MCID estimates ranging between ?3.0 and ?2.0 points for CAT; ?0.5 and ?0.3 points for CCQ, ?1.8 and ?1.3 points for HADS-Anxiety, and ?1.7 and ?1.5 points for HADS-Depression.  相似文献

Objectives

A simple and inexpensive tool for screening of sarcopenia would be helpful for clinicians. The present study was performed to determine whether the SARC-F questionnaire is useful in screening of patients with cardiovascular disease (CVD) for impaired physical function.

Design

Cross-sectional study.

Setting

Single university hospital.

Participants

A total of 235 Japanese patients ≥65 years old admitted to our hospital for CVD.

Measurements

SARC-F, handgrip strength, leg strength, respiratory muscle strength, standing balance, usual gait speed, Short Physical Performance Battery (SPPB) score, and 6-minute walking distance were measured before discharge from hospital. The patients were divided into 2 groups according to SARC-F score: SARC-F < 4 (nonsarcopenia group) and SARC-F ≥ 4 (sarcopenia group).

Results

The sarcopenia prevalence rate was 25.5% and increased with age (P trend < .001). The sarcopenia group (SARC-F score ≥ 4) had significantly lower handgrip strength, leg strength, and respiratory muscle strength, poorer standing balance, slower usual gait speed, lower SPPB score, and shorter 6-minute walking distance compared to the nonsarcopenia group (SARC-F score < 4). Patients in the sarcopenia group had consistently poorer physical function even after adjusting for covariates.

Conclusion

The SARC-F questionnaire is a useful screening tool for impaired physical function in elderly CVD patients. These findings support the use of the SARC-F for screening in hospital settings.  相似文献

Objectives

The distinction between dementia and mild cognitive impairment (MCI) relies upon the evaluation of independence in instrumental activities of daily living (IADL). Self- and informant reports are prone to bias. Clinician-based performance tests are limited by long administration times, restricted access, or inadequate validation. To close this gap, we developed and validated a performance-based measure of IADL, the Sydney Test of Activities of Daily Living in Memory Disorders (STAM).

Design

Prospective cohort study (Sydney Memory and Ageing Study).

Setting

Eastern Suburbs, Sydney, Australia.

Participants

554 community-dwelling individuals (54% female) aged 76 and older with normal cognition, MCI, or dementia.

Measurements

Activities of daily living were assessed with the STAM, administered by trained psychologists, and the informant-based Bayer-Activities of Daily Living Scale (B-ADL). Depressive symptoms were measured with the Geriatric Depression Scale (15-item version). Cognitive function was assessed with a comprehensive neuropsychological test battery. Consensus diagnoses of MCI and dementia were made independently of STAM scores.

Results

The STAM showed high interrater reliability (r = 0.854) and test-retest reliability (r = 0.832). It discriminated significantly between the diagnostic groups of normal cognition, MCI, and dementia with areas under the curves ranging from 0.723 to 0.948. A score of 26.5 discriminated between dementia and nondementia with a sensitivity of 0.831 and a specificity of 0.864. Correlations were low with education (r = 0.230) and depressive symptoms (r = ?0.179), moderate with the B-ADL (r = ?0.332), and high with cognition (ranging from r = 0.511 to r = 0.594). The mean time to complete the STAM was 16 minutes.

Conclusions

The STAM has good psychometric properties. It can be used to differentiate between normal cognition, MCI, and dementia and can be a helpful tool for diagnostic classification both in clinical practice and research.  相似文献

Objectives

To investigate the prevalence and factors associated with the use of medications of questionable benefit throughout the final year of life of older adults who died with dementia.

Design

Register-based, longitudinal cohort study.

Setting

Entire Sweden.

Participants

All older adults (≥75 years) who died with dementia between 2007 and 2013 (n = 120,067).

Measurements

Exposure to medications of questionable benefit was calculated for each of the last 12 months before death, based on longitudinal data from the Swedish Prescribed Drug Register.

Results

The proportion of older adults with dementia who received at least 1 medication of questionable benefit decreased from 38.6% 12 months before death to 34.7% during the final month before death (P < .001 for trend). Among older adults with dementia who used at least 1 medication of questionable benefit 12 months before death, 74.8% remained exposed until their last month of life. Living in an institution was independently associated with a 15% reduction of the likelihood to receive ≥1 medication of questionable benefit during the last month before death (odds ratio 0.85, 95% confidence interval 0.88–0.83). Antidementia drugs accounted for one-fifth of the total number of medications of questionable benefit. Lipid-lowering agents were used by 8.3% of individuals during their final month of life (10.2% of community-dwellers and 6.6% of institutionalized people, P < .001).

Conclusion

Clinicians caring for older adults with advanced dementia should be provided with reliable tools to help them reduce the burden of medications of questionable benefit near the end of life.  相似文献

Background

A consensus panel, based on epidemiologic evidence, argued that physical frailty is often associated with cognitive impairment, possibly because of common underlying pathophysiological mechanisms. The concepts of cognitive frailty and motoric cognitive risk were recently proposed in literature and may represent a prodromal stage for neurodegenerative diseases. The purpose of this study was to analyze the relationship between cognition and the components of the physical phenotype of frailty.

Methods

Participants admitted to the Toulouse frailty day hospital aged 65 years or older were included in this cross-sectional study. Cognitive impairment was identified using the Mini-Mental State Examination (MMSE) and the Clinical Dementia Rating (CDR). Frailty was assessed using the physical phenotype as defined by Fried's criteria. We divided the participants into 2 groups: participants with normal cognition (CDR = 0) and participants who had cognitive impairment (CDR = 0.5). Participants with CDR >0.5 were excluded.

Results

Data from 1620 participants, mean age 82 years and 63% of women were analyzed. Cognitive impairment was identified in 52.5% of the participants. Frailty was identified in 44.7% of the sample. There were more frail subjects in the impaired group than the normal cognitive group (51% vs 38%, P < .001). In logistic regression analyses, elevated odds for frailty were observed in patients with cognitive impairment [adjusted odds ratio (OR) 1.66, 95% confidence interval (CI) 1.12-2.46]. Subsequent analysis showed that the association between cognitive impairment and frailty was only observed considering one of the 5 frailty criteria: gait speed (adjusted OR 1.89, 95% CI 1.55-2.32).

Conclusion

Physical frailty and in particular slow gait speed were associated with cognitive impairment. Future research including longitudinal studies should exploit the association between cognitive impairment and frailty.  相似文献

Objective

We quantified transdermal fentanyl prescribing in elderly nursing home residents without prior opioid use or persistent pain, and the association of individual and facility traits with opioid-naïve prescribing.

Design

Cross-sectional study.

Setting

Linked Minimum Data Set (MDS) assessments; Online Survey, Certification and Reporting (OSCAR) records; and Medicare Part D claims.

Participants

From a cross-section of all long-stay US nursing home residents in 2008 with an MDS assessment and Medicare Part D enrollment, we identified individuals (≥65 years old) who initiated transdermal fentanyl, excluding those with Alzheimer disease, severe cognitive impairment, cancer, or receipt of hospice care.

Measurements

We used Medicare Part D to select beneficiaries initiating transdermal fentanyl in 2008 and determined whether they were “opioid-naïve,” defined as no opioid dispensing during the previous 60 days. We obtained resident and facility characteristics from MDS and OSCAR records and defined persistent pain as moderate-to-severe, daily pain on consecutive MDS assessments at least 90 days apart. We estimated associations of patient and facility attributes and opioid-naïve fentanyl initiation using multilevel mixed effects logistic regression modeling.

Results

Among 17,052 residents initiating transdermal fentanyl, 6190 (36.3%) were opioid-naïve and 15,659 (91.8%) did not have persistent pain. In the regression analysis with adjustments, residents who were older (ages ≥95 odds ratio [OR] 1.69, 95% confidence interval [CI] 1.46–1.95) or more cognitively impaired (moderate-to-severe cognitive impairment, OR 1.99, 95% CI 1.73–2.29) were more likely to initiate transdermal fentanyl without prior opioid use.

Conclusion

Most nursing home residents initiating transdermal fentanyl did not have persistent pain and many were opioid-naïve. Changes in prescribing practices may be necessary to ensure Food and Drug Administration warnings are followed, particularly for vulnerable subgroups, such as the cognitively impaired.  相似文献
