The principles of promoting autonomy and independence underpin many approaches to improving the quality of nursing care for older people in whatever setting, and are in line with wider developments in health care such as the Patient's Charter. However, these concepts require careful definition if nursing practices which might promote autonomy and independence are to be identified. Although the generalizability of the research-based literature in this field is limited by a focus upon older people in continuing-care settings, a review of the literature found a number of indicators associated with attempts to promote patient autonomy and independence. These were grouped into the following categories: systems of care delivery which promote comprehensive individualized assessment and multidisciplinary care planning; attempts to encourage patients/clients to participate in decisions about their care; patterns of communication which avoid exerting power and control over patients/clients and attempts to modify the environment to promote independence and minimize risk. It is suggested that the review identifies a number of principles for nursing practice which can be applied in a range of care settings in order to promote the autonomy and independence of older people.  相似文献

This paper reflects on a research project funded by a consortium of leading sheltered housing (SH) providers and their regulatory body, the Housing Corporation. The project aimed to ascertain which aspects of SH older people perceived to be central to their satisfaction and the methods they judged most appropriate to measuring this. We outline key policy developments of importance to SH (specifically the development of performance measurement regimes), and changes in the nature of SH, which are driving providers to re‐evaluate how they measure user satisfaction. We discuss the aims of the project, our methodology and findings, and conclude by raising critical questions about the process of measuring satisfaction within an increasingly managerialised housing system. We argue that this favours standardised methods of information gathering (such as questionnaires) rather than engage with clients in order to develop methods and systems capable of eliciting qualitative issues of concern to them. Our conclusions are, we believe, applicable to health and social care provision, where similar tensions exist around performance measurement and user satisfaction.  相似文献

The mortality and suicide rates for involuntarily committed patients in Denmark are presented. Two cohorts of psychiatric patients committed to a mental hospital from January 1, 1971 to December 31, 1975 (8322 people) and January 1, 1981 to December 31, 1985 (5253 people) have been followed. The standard mortality rate (SMR) in relation to the total Danish population were 4.9 (4.5–5.4) and 5.2 (4.7–5.8), respectively, for the two cohorts, during the first year after involuntarily commitment to a mental hospital. During the same period, the SMR for suicide among the committed patients were 44.9 (37.1–53.9) and 30.9 (24.2–38.9), respectively. The crude suicide rates among the committed patients during the first year after the commitment were 14.3 and 14.0, respectively, per 1000 years, unchanged between the cohorts. Short length of stay in hospital (< 14 days), a nonpsychotic main diagnosis, male sex, and age 35 years or more were equally related to high risk of suicide in the 1971 cohort as evaluated to proportional hazard methods (Cox regression), and short length of stay and commitment on the danger indication provided the most information in relation to high suicidal risk in the 1981 cohort. Methodological problems and the reasons for the results are discussed.  相似文献

Aim:   This paper presents social science understandings of successful aging for a broad audience in multidisciplinary gerontology in Asia–Oceania.
Methods:   The international literature on social science aspects of successful aging is reviewed with a focus on Asia and social improvement.
Results:   New positive approaches to aging research are identifying opportunities for maintaining capacities and well-being over the life course. Successful aging, productive aging, and active aging are key concepts. Increasing life expectancy and fertility control are major social achievements that underpin population aging as the mainstream social transformation facing the world. Asia will be at the forefront of this change and the consequences will vary greatly between cultures, nations, and subgroups within them. Older people generally maintain good quality of life and the capacity to 'age well' is influenced by life-long maturation and emotional, social, and economic resources. Good health can be enhanced through positive actions such as physical activity, good nutrition, and not smoking. Mental capacities can also be improved and maintained throughout old age. In advanced old age, the 'fourth age', the focus turns to ameliorating the effects of loss and to maintaining dignity.
Conclusions:   The social sciences contribute knowledge useful for improving life experiences for older people and aging societies. Population aging is central to national economic development. Public policy and individual action concerning aging can benefit all age groups. To better inform these developments it is important to address the serious shortfall of social science research on aging in the Asia–Oceania region.  相似文献
