Falls and health status in elderly women following second eye cataract surgery: a randomised controlled trial.

OBJECTIVE: first eye cataract surgery reduces the risk of falling. Most cataracts in elderly people are bilateral. Some binocular functions (e.g. stereopsis) are associated with falls. We aimed to determine if second eye cataract surgery reduces the risk of falling and to measure associated health gain. STUDY DESIGN AND SETTING: we randomised 239 women over 70, who had been referred to a hospital ophthalmology department, with one unoperated cataract, to expedited (approximately 4 weeks) or routine (12 months wait) surgery. Falls were ascertained by diary, with follow-up every 3 months for 12 months. We measured health status after 6 months. RESULTS: visual function (especially stereopsis) improved in the operated group. Over 12 months follow-up, 48 (40%) operated participants fell at least once, 22 (18%) fell more than once. Forty-one (34%) unoperated participants fell at least once, 22 (18%) fell more than once. Rate of falling was reduced by 32% in the operated group, but this was not statistically significant (rate ratio 0.68, 95% CI 0.39, 1.19, P = 0.18). Confidence, visual disability and handicap all improved in the operated compared with the control group. CONCLUSION: second eye cataract surgery improves visual disability and general health status. The effect on rate of falling remains uncertain.

What constitutes health-related quality of life in dementia? Development of a conceptual framework for people with dementia and their carers.

BACKGROUND: The evaluation of multi-dimensional outcomes such as health-related quality of life (HRQL) is particularly relevant in dementia where the disease can compromise all areas of functioning. The nature of dementia can make self-report difficult, yet the subjective nature of HRQL makes the value of proxy reports limited. Previous work suggests that there are domains of HRQL that are unique to dementia. We aimed to develop a conceptual framework of HRQL in dementia from the perspective of people with dementia and their carers and to examine differences in the reports of the HRQL of these two groups. METHODS: We combined existing literature and new qualitative data to develop the conceptual framework and analysed qualitative data using content analysis. RESULTS: We identified five domains: daily activities and looking after yourself, health and well-being, cognitive functioning, social relationships and self-concept, and each was defined by specific descriptive components. There were differences between people with dementia and carers in the way they described these domains. CONCLUSIONS: We have developed a conceptual framework of HRQL in dementia that incorporates the views of people with dementia and their carers. This provides the basis for the development of a new measure of HRQL in dementia (DEMQOL).

A randomised, controlled comparison of different calcium and vitamin D supplementation regimens in elderly women after hip fracture: The Nottingham Neck of Femur (NONOF) Study.

BACKGROUND: survivors of hip fracture are at 5- to 10-fold risk of a second hip fracture. There is little consensus about secondary prevention. Many are given calcium and vitamin D, but the evidence supporting this is circumstantial. OBJECTIVE: to compare the effects of different calcium and vitamin D supplementation regimens on bone biochemical markers, bone mineral density and rate of falls in elderly women post-hip fracture. DESIGN: randomised controlled trial. SETTING: orthogeriatric rehabilitation ward. METHODS: 150 previously independent elderly women, recruited following surgery for hip fracture, were assigned to receive a single injection of 300,000 units of vitamin D(2), injected vitamin D(2) plus 1 g/day oral calcium, 800 units/day oral vitamin D(3) plus 1 g/day calcium, or no treatment. Follow-up was one year, with measurement of 25-hydroxyvitamin D, parathyroid hormone, bone mineral density, and falls. RESULTS: mean 25-hydroxyvitamin D increased and mean parathyroid hormone was suppressed in all the actively treated groups, more so in the group receiving combined oral vitamin D and calcium. Twenty per cent of participants injected with vitamin D were deficient in 25-hydroxyvitamin D a year later. Bone mineral density showed small but statistically significant differences of up to 4.6% between actively treated groups and placebo. Relative risk of falling in the groups supplemented with vitamin D was 0.48 (95% CI 0.26-0.90) compared with controls. CONCLUSION: Vitamin D supplementation, either orally or with injected vitamin D, suppresses parathyroid hormone, increases bone mineral density and reduces falls. Effects may be more marked with calcium co-supplementation. The 300,000 units of injected vitamin D may not last a whole year.

Sooner and healthier: a randomised controlled trial and interview study of an early discharge rehabilitation service for older people.

BACKGROUND: Hospitals are under pressure from admissions of increasing numbers of older people. Older people may suffer unnecessary activity limitation after acute illnesses through lack of appropriate rehabilitation. OBJECTIVE: To evaluate an early discharge and rehabilitation service for older people. DESIGN: A randomised controlled trial comparing an early discharge and rehabilitation with standard hospital aftercare. Outcome measures assessed at 3 and 12 months were the Barthel Index, Nottingham Extended Activities of Daily Living and EuroQol (for patients) the General Health Questionnaire (for patients and carers). Use of services over 12 months was recorded. An interview study of patients and staff was conducted. SETTING AND INTERVENTION: The early discharge and rehabilitation service offered a home-based rehabilitation and care programme for up to 4 weeks. PARTICIPANTS: 370 hospitalised older medical and surgical patients were included in the randomised controlled trial. Twenty patients and 11 staff were interviewed. RESULTS: Subjects in the early discharge rehabilitation service group used fewer days in hospital at 3 months (mean difference 9, median difference 4 days, 95% CI of median difference 2-8). At 3 months the early discharge and rehabilitation service patients had better Barthel scores (mean difference 1.2, 95% CI 0.4-1.9), Nottingham Extended Activities of Daily Living kitchen scores (mean difference 1.2, 95% CI 0.2-2.3), Nottingham Extended Activities of Daily Living domestic scores (mean difference 1.1, 95% CI 0.2-2.0) and General Health Questionnaire scores (mean difference 2.4, 95% CI 0.7-4.1). Significant Nottingham Extended Activities of Daily Living domestic and General Health Questionnaire benefits remained at 12 months. The early discharge and rehabilitation service carers had better General Health Questionnaire scores at 3 months (mean difference 2.0, 95% CI 0.1-3.8). The interviews suggested that the early discharge and rehabilitation service was patient-centred, set clear goals, worked as a team, and considered physical, psychological, social and environmental issues. It was found to be highly satisfactory. CONCLUSIONS: Some older people can be discharged from hospital sooner, with better health outcomes using a well-staffed and organised patient-centred early discharge service providing rehabilitation.

Current and future worldwide prevalence of dependency, its relationship to total population, and dependency ratios.

OBJECTIVE: To estimate the number of people worldwide requiring daily assistance from another person in carrying out health, domestic or personal tasks. METHODS: Data from the Global Burden of Disease Study were used to calculate the prevalence of severe levels of disability, and consequently, to estimate dependency. Population projections were used to forecast changes over the next 50 years. FINDINGS: The greatest burden of dependency currently falls in sub-Saharan Africa, where the "dependency ratio" (ratio of dependent people to the population of working age) is about 10%, compared with 7-8% elsewhere. Large increases in prevalence are predicted in sub-Saharan Africa, the Middle East, Asia and Latin America of up to 5-fold or 6-fold in some cases. These increases will occur in the context of generally increasing populations, and dependency ratios will increase modestly to about 10%. The dependency ratio will increase more in China (14%) and India (12%) than in other areas with large prevalence increases. Established market economies, especially Europe and Japan, will experience modest increases in the prevalence of dependency (30%), and in the dependency ratio (up to 10%). Former Socialist economies of Europe will have static or declining numbers of dependent people, but will have large increases in the dependency ratio (up to 13%). CONCLUSION: Many countries will be greatly affected by the increasing number of dependent people and will need to identify the human and financial resources to support them. Much improved collection of data on disability and on the needs of caregivers is required. The prevention of disability and provision of support for caregivers needs greater priority.

Specialist nurses to evaluate elderly in-patients referred to a department of geriatric medicine.

BACKGROUND: Increasing numbers of elderly patients are admitted to hospital. Ensuring that they are given appropriate and timely access to the range of hospital and community medical, rehabilitation and social care facilities has become more difficult due to the complexity of management options now available, and limited senior medical staff time. METHODS: We established a scheme in which specialist nurses made first assessments of all inter-departmental referrals to a hospital department of geriatric medicine. We evaluated the scheme prospectively using process and outcome data. RESULTS: 2825 new patients were seen by two nurses in the first two years, an average of 5.4 per weekday (range 0-17). Mean time from admission to referral was 9 days. Most referrals were seen within 1 day. Mean total length of hospital stay was 43 days (range 1-351). Seven percent died on the referring ward, and 31% were discharged directly from the referring ward. Almost half were accepted for in-patient rehabilitation. Sixty percent of these were discharged home. Thirteen percent were transferred to an acute geriatric medical or stroke ward. One-quarter of these died. Senior medical review was requested in 8% of cases. CONCLUSIONS: Nurses could select patients suitable for rehabilitation, identify those requiring on-going acute in-patient care, and make arrangements for supported direct discharges where appropriate. This model facilitated access to a wide array of discharge and community support schemes, and supported the efficient use of consultant time.
