Cardiovascular risk profile and frailty in a population-based study of older British men

BACKGROUND

Frailty in older age is known to be associated with cardiovascular disease (CVD) risk. However, the extent to which frailty is associated with the CVD risk profile has been little studied. Our aim was to examine the associations of a range of cardiovascular risk factors with frailty and to assess whether these are independent of established CVD.

METHODS

Cross-sectional study of a socially representative sample of 1622 surviving men aged 71-92 examined in 2010-2012 across 24 British towns, from a prospective study initiated in 1978-1980. Frailty was defined using the Fried phenotype, including weight loss, grip strength, exhaustion, slowness and low physical activity.

RESULTS

Among 1622 men, 303 (19%) were frail and 876 (54%) were pre-frail. Compared with non-frail, those with frailty had a higher odds of obesity (OR 2.03, 95% CI 1.38 to 2.99), high waist circumference (OR 2.30, 95% CI 1.67 to 3.17), low high-density lipoprotein-cholesterol (HDL-C) (OR 2.28, 95% CI 1.47 to 3.54) and hypertension (OR 1.79, 95% CI 1.27 to 2.54). Prevalence of these factors was also higher in those with frailty (prevalence in frail vs non-frail groups was 46% vs 31% for high waist circumference, 20% vs 11% for low HDL and 78% vs 65% for hypertension). Frail individuals had a worse cardiovascular risk profile with an increased risk of high heart rate, poor lung function (forced expiratory volume in 1 s (FEV1)), raised white cell count (WCC), poor renal function (low estimated glomerular filtration rate), low alanine transaminase and low serum sodium. Some risk factors (HDL-C, hypertension, WCC, FEV1, renal function and albumin) were also associated with being pre-frail. These associations remained when men with prevalent CVD were excluded.

CONCLUSIONS

Frailty was associated with increased risk of a range of cardiovascular factors (including obesity, HDL-C, hypertension, heart rate, lung function, renal function) in older people; these associations were independent of established CVD.

The potential of case management for people with dementia: a commentary

BACKGROUND

A recent review of studies of case management in dementia argues that lack of evidence of cost-effectiveness should discourage the use of this approach to care. We argue that that this is too conservative a stance, given the urgent need throughout the world to improve the quality of care for people with dementia and their caregivers. We propose a research agenda on case management for people with dementia.

METHOD

A critical comparison was made of the studies identified in two systematic reviews of trials of case management for dementia, with selective inclusion of non-trial studies and economic evaluations.

RESULTS

Our interpretation of the literature leads us to four provisional conclusions. First, studies with long follow-up periods tend to show delayed relocation of people with dementia to care homes. Second, the quality of life of people with dementia and their caregivers may also influence the likelihood of relocation. Third, different understandings of what constitutes case management make interpretation of studies difficult. Fourth, we agree that the population most likely to benefit from case management needs to be characterised. Earlier intervention may be more beneficial than intervening when the condition has progressed and the individual's situation is highly complex. However, this runs counter to some definitions of case management as an administrative, professional, and systemic focus on people with high needs and where expensive support is accessed or in prospect.

CONCLUSIONS

More work needs to be carried out in a more focused way in order to establish the value of case management for people with dementia. Since care home residence is such a sizeable contributor to the costs of dementia care, studies need to be long enough to capture possible postponed relocation. However, case management studies with shorter follow-up periods can still contribute to our understanding, since they can demonstrate improved quality of life. Future research should be built around a common, agreed definition of types of case management.

User involvement in the development of a health promotion technology for older people: findings from the SWISH project

Successive English government policies about older people's health and well-being aim to improve health and quality of life by promoting independence. Improving access to information and services that can improve health and well-being and reduce health risks is central to the modernisation of health and social care. Most recently, tailored and person-centred approaches with a strong emphasis on promoting health and well-being are central to policy, including the proposals for 'Life Checks' and the recent emphasis on commissioning 'community well-being'. We carried out a qualitative study to identify the key aspects of social situations that affect health and well-being, from the perspectives of older people and professionals, to enrich and expand an existing health risk appraisal tool so that it could be used for self-assessment of health and social well-being. This tool, Health Risk Appraisal in Older people (HRAO), has been evaluated in different European settings, including English general practice. Focus groups were recruited from general practice, older people's forums, social care and voluntary organisations in two London boroughs where the HRAO tool had previously been tested. The social factors determining health that were prioritised by older people and service providers and recommended for inclusion in the health risk appraisal tool were recent life events, housing and garden maintenance, transport, both public and private, financial management, career status & needs, the local environment and social networks and social isolation. This study has identified key social determinants of health that could usefully be added to 'Life Checks' for older people and that could also inform the commissioning of community well-being. Modified with the addition of social domains, the HRAO technology could be a suitable tool to achieve current policy objectives.

The primary care physician and Alzheimer's disease: an international position paper

This paper aims to define the role of the primary care physician (PCP) in the management of Alzheimer's disease (AD) and to propose a model for a work plan. The proposals in this position paper stem from a collaborative work of experts involved in the care of AD patients. It combines evidence from a literature review and expert's opinions who met in Paris, France, on July 2009 during the International Association of Geriatrics and Gerontology (IAGG) World Congress. The PCP's intervention appears essential at many levels: detection of the onset of dementia, diagnostic management, treatment and follow-up. The key role of the PCP in the management of AD, as care providers and care planners, is consolidated by the family caregiver's confidence in their skills. In primary care practice the first step is to identify dementia. The group proposes a "case finding" strategy, in target situations in which dementia should be detected to allow, secondarily, a diagnosis of AD, in certain cases. We propose that the PCP identifies 'typical' cases. In typical cases, among older subjects, the diagnosis of "probable AD" can be done by the PCP and then confirm by the specialist. While under-diagnosis of AD exists, so does under-disclosure. Disclosure to patient and family should be done by both specialist and PCP. Then, the PCP has a central role in management of the disease with the general objectives to detect, prevent and treat, when possible, the complications of the disease (falls, malnutrition, behavioural and psychological symptoms of dementia). The PCP needs to give basic information to the caregiver on respite care and home support services in order to prevent crisis situations such as unplanned institutionalisation and "emergency" hospital admission. Finally, therapeutic research must be integrated in the daily practice of PCP. It is a matter of patients' right to benefit from access to innovation and clinical research whatever his age or diseases, while of course fully respecting the rules and protective measures that are in force.

Promoting older peoples' participation in activity, whose responsibility? A case study of the response of health, local government and voluntary organizations

The benefits for older people of participating in regular activity are well documented. This paper focuses on how publicly funded community-based organizations enable older people to engage in physical activity. The research questions were: (i) What activity promotion schemes/initiatives exist for older people? (ii) Who has responsibility for them, how are they funded and organized and what evidence exists of interagency working? (iii) Who are the older people that participate? (iv) What are the perceived and measurable outcomes of the initiatives identified? To establish the type and range of provision for older people in a sector of London, the strategies and information about existing activity promoting schemes of inner city health, local government and voluntary organizations were reviewed. Key informants were then interviewed to establish the rationale, achievements and different schemes. One hundred and nine activity-promoting initiatives for older people were identified. Most were provided within an environment of short-term funding and organizational upheaval and reflected eclectic theoretical and ideological approaches. The findings demonstrate: (i) the need for organizations to apply evidence about what attracts and sustains older people's participation in physical activity, and (ii) the need to develop funded programmes that build on past achievements, have explicit outcomes and exploit opportunities for cross agency working.

The primary care diagnosis of dementia in Europe: an analysis using multidisciplinary, multinational expert groups

OBJECTIVES

To explore the extent of variation in the detection of dementia in primary care across Europe, and the potential for the development of European guidelines.

METHOD

A mixture of focus group and adapted nominal group methods involving 23 experts of different disciplines and from eight European countries.

RESULTS

The diagnosis of dementia should be 'timely' rather than 'early'. Timeliness has an impact on the patient, on the caregiver, on healthcare professionals, and on society. Ethical and moral issues may interfere with the aim of timely diagnosis. Guidelines may be important for facilitating a timely diagnosis of dementia, but were infrequently used and not even available in three of the eight countries. Referral pathways often depended on health care system characteristics, differing throughout the eight European countries, whilst diagnostic strategies differed due to varied cultural influences. There was consensus that national variations can be reduced and timely diagnosis enhanced by combining simple tests using a systematic stepwise case-finding strategy, in conjunction with a strong infrastructure of multidisciplinary collaboration.

CONCLUSIONS

This study identified three key themes that should be considered in harmonizing European approaches to the diagnosis of dementia in primary care: (1) a focus on timely diagnosis, (2) the need for the development and implementation of guidelines, and (3) the identification of appropriate referral pathways and diagnostic strategies including multi-professional collaboration. The content of guidelines may be determined by the perspectives of the guideline developers.

Community screening for visual impairment in the elderly

BACKGROUND

While the aims of multicomponent screening of older people are broad, any benefit arising from the inclusion of a vision component in the assessment will necessarily be dependent on improving vision.

OBJECTIVES

To assess the effects on vision of mass screening of older people for visual impairment.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), which contains the Cochrane Eyes and Vision Group Trials Register, in The Cochrane Library (Issue 1, 2006), NRR (Issue 1, 2006), MEDLINE (1966 to February 2006), EMBASE (1980 to February 2006), PubMed (on 8th March; last 90 days), SciSearch and reference lists of relevant trial reports and review articles. We contacted investigators to identify additional published and unpublished trials.

SELECTION CRITERIA

We included randomised trials of visual or multicomponent screening for identifying vision impairment in people aged 65 years or over in a community setting.

DATA COLLECTION AND ANALYSIS

Both authors independently extracted data and assessed trial quality.

MAIN RESULTS

Visual outcome data were available for 3494 people in five trials of multicomponent assessment. Length of follow up ranged from two to four years. All the trials used self-reported measures for visual impairment, both as screening tools and as outcome measures. In four of the trials people reporting visual problems were referred to either eye services or a physician. In one trial people reporting visual problems received information about resources in the community designed to assist those with poor vision. The proportions of participants in the intervention and control groups who reported visual problems at the time of outcome assessment were 0.26 and 0.23 respectively (risk ratio for visual impairment 1.03, 95% confidence interval (CI) 0.92 to 1.15). Visual outcome data were also available for 1807 people aged 75 years and over in a cluster randomised trial in which physicians' general practices were randomised to two different screening strategies; universal or targeted. Three to five years after screening, the risk ratio for visual acuity less than 6/18 in either eye comparing universal with targeted screening was 1.07 (95% CI 0.84 to 1.36, P = 0.58). The mean composite score of the National Eye Institute 25 item visual function questionnaire was 85.6 in the targeted screening group and 86.0 in the universal group, a difference of 0.4 (95% CI -1.7 to 2.5, P = 0.69).

AUTHORS' CONCLUSIONS

There is no evidence that community-based screening of asymptomatic older people results in improvements in vision.

Physiological correlates of cognitive functioning in an elderly population

Cognitive decline in old age is not universal or inevitable. Associations have been observed with neuroendocrine function, but the relevance of other physiological processes is unclear. We predicted that impairment of memory in an ageing population would be related to the dysregulation of neuroendocrine and cardiovascular responses. One hundred and thirty-nine participants (65-80 years) were recruited from general practice in London. Two standardised verbal paired-associates recall tasks were administered in order to determine declarative memory performance, and a fluid intelligence task (matrix reasoning) was also performed. Salivary cortisol samples were collected every 10 min, while blood pressure and heart rate were measured before, during and after each task. Illness history and medication use were obtained from medical records. Multiple linear regression analysis, adjusted for age, gender, education, chronic illness, and medication use, revealed that cortisol responses were inversely related to memory performance. Additionally, superior memory was associated with more effective post-task recovery of heart rate (in both men and women) and diastolic blood pressure recovery in men. Cardiovascular recovery effects were independent of covariates, and of levels of heart rate and blood pressure measured during tasks themselves. These associations were also independent of subjective ratings of stress and perceived performance. Neither neuroendocrine nor cardiovascular responses were related to performance of the reasoning task. We conclude that memory in the elderly is associated both with hypothalamic-pituitary-adrenocortical function and cardiovascular regulation. Disturbances of neuroendocrine and hemodynamic function may be related to greater vulnerability to cognitive decline.

Hospital at home versus in-patient hospital care

BACKGROUND

Hospital at home is defined as a service that provides active treatment by health care professionals, in the patient's home, of a condition that otherwise would require acute hospital in-patient care, always for a limited period.

OBJECTIVES

To assess the effects of hospital at home compared with in-patient hospital care.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group (EPOC) specialised register (November 2004), MEDLINE (1966 to 1996), EMBASE (1980 to 1995), Social Science Citation Index (1992 to 1995), Cinahl (1982 to 1996), EconLit (1969 to 1996), PsycLit (1987 to 1996), Sigle (1980 to 1995) and the Medical Care supplement on economic literature (1970 to 1990).

SELECTION CRITERIA

Randomised trials of hospital at home care compared with acute hospital in-patient care. The participants were patients aged 18 years and over.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed study quality.

MAIN RESULTS

Twenty two trials are included in this update of the review. Among trials evaluating early discharge hospital at home schemes we found an odds ratio (OR) for mortality of 1.79 95% CI 0.85 to 3.76 for elderly medical patients (age 65 years and over) (n = 3 trials); OR 0.58; 95% CI 0.29 to 1.17 for patients with chronic obstructive pulmonary disease (COPD) (n = 5 trials); and OR 0.78; 95%CI 0.52 to 1.19 for patients recovering from a stroke (n = 4 trials). Two trials evaluating the early discharge of patients recovering from surgery reported an OR 0.43 (95% CI 0.02 to 10.89) for patients recovering from a hip replacement and an OR 1.01 (95% CI 0.37 to 2.81) for patients with a mix of conditions at three months follow-up. For readmission to hospital we found an OR 1.76; 95% CI 0.78 to 3.99 at 3 months follow-up for elderly medical patients (n = 2 trials); OR 0.81; 95% CI 0.55 to 1.19 for patients with COPD (n = 5 trials); and OR 0.96; 95% CI 0.63 to 1.45 for patients recovering from a stroke (n = 3 trials). No significant heterogeneity was observed. One trial recruiting patients following surgery for hernia or varicose veins reported 0/117 versus 2/121 patients were re admitted (Ruckley 1978); another that 2/37 (5%) versus 1/49 (2%) (difference 3%, 95% CI -5% to 12%) of patients recovering from a hip replacement, 4/47 (9%) versus 1/39 (3%) (difference 6%, 95% CI -3% to 15%) of patients recovering from a knee replacement, and 7/114 (6%) versus 13/124 (10%) (difference -4% 95% CI -11% to 3%) of patients recovering from a hysterectomy were readmitted. A third trial analysing surgical and medical patients together reported that 42/159 versus 17/81 patients were readmitted at 3 months (OR 1.34 95% CI 0.66 to 2.20). Allocation to hospital at home resulted in a small reduction in hospital length of stay, but hospital at home increased overall length of care. Patients allocated to hospital at home expressed greater satisfaction with care than those in hospital, while the view of carers was mixed.

AUTHORS' CONCLUSIONS

Despite increasing interest in the potential of hospital at home services as a cheaper alternative to in-patient care, this review provides insufficient objective evidence of economic benefit. Early discharge schemes for patients recovering from elective surgery and elderly patients with a medical condition may have a place in reducing the pressure on acute hospital beds, providing the views of the carers are taken into account. For these clinical groups hospital length of stay is reduced, although this is offset by the provision of hospital at home. Future primary research should focus on rigorous evaluations of admission avoidance schemes and standards for original research should aim at assisting future meta-analyses of individual patient data from these and future trials.

Health risk appraisal for older people in general practice using an expert system: a pilot study

The prevention of disability in later life is a major challenge facing industrialised societies. Primary care practitioners are well positioned to maintain and promote health in older people, but the British experience of population-wide preventive interventions has been disappointing. Health risk appraisal (HRA), an emergent information-technology-based approach from the USA, has the potential for fulfilling some of the objectives of the National Service Framework for Older People. Information technology and expert systems allow the perspectives of older people on their health and health risk behaviours to be collated, analysed and converted into tailored health promotion advice without adding to the workload of primary care practitioners. The present paper describes a preliminary study of the portability of HRA to British settings. Cultural adaptation and feasibility testing of a comprehensive health risk assessment questionnaire was carried out in a single group practice with 12,500 patients, in which 58% of the registered population aged 65 years and over participated in the study. Eight out of 10 respondents at all ages found the questionnaire easy or very easy to understand and complete, although more than one-third had or would have liked assistance. More than half felt that the length of the questionnaire was about right, and one respondent in 10 disliked some questions. Of those who completed the questionnaire and received tailored, written health promotion advice, 39% provided feedback on this with comments that can be used for increasing the acceptability of tailored advice. These findings have informed a wider exploratory study in general practice.

Understanding obstacles to the recognition of and response to dementia in different European countries: a modified focus group approach using multinational, multi-disciplinary expert groups

Experts from eight European countries (Belgium, France, The Netherlands, Ireland, Italy, Portugal, Spain and the United Kingdom) and the disciplines of clinical psychology, general practice, geriatric medicine, old age psychiatry, medical sociology, nursing and voluntary body organisation met in 2003 to explore obstacles to recognition of and response to dementia in general practice within Europe. A modified focus group methodology was used in this exploratory process. Groups were conducted over a two-day period, with five sessions lasting 1-1.5 hours each. An adapted nominal group method was used to record themes arising from the group discussion, and these themes were used in a grounded theory approach to generate explanations for delayed recognition of and response to dementia. The overarching theme that arose from the focus groups was movement, which had three different expressions. These were: population movement and its consequences for localities, services and professional experience; the journey of the person with dementia along the disease process; and the referral pathway to access services and support. Change is the core issue in dementia care, with multiple pathways of change that need to be understood at clinical and organisational levels. Practitioners and people with dementia are engaged in managing emotional, social and physical risks, making explicit risk management a potentially important component of dementia care. The boundary between generalist and specialist services is a particular problem, with great potential for dysfunctionality. Stigma and ageism are variably distributed phenomena both within and between countries.
