Within the UK, there is growing recognition that individuals will need to take increased responsibility for managing their own health for there to be improvements in population health. The current evidence base on self care interventions reflects an interest in enhancing self care knowledge, skills and behaviour in relation to the management of long‐term conditions. In contrast, this paper reports on a community‐based self care initiative that was designed to promote self care approaches in the general population. The principal component was a self care skills training course delivered to groups of lay people in community and workplace settings. Self Care for People was piloted in three primary care trusts and a process evaluation was undertaken. The aim of this paper is to examine the feasibility, relevance and acceptability of the initiative. Qualitative interviews were conducted with a sample of stakeholders involved in implementation including coordinators, trainers and key informants from organisations hosting the course. In total 40 interviews and two focus groups were conducted from 2006 to 2008 and the data were analysed thematically. The evaluation found that implementation was relatively straightforward with few major barriers reported. Recruitment to the self care skills training course took place in both workplace and community group settings, including in organisations supporting socially excluded groups. The course was seen to provide a valuable space for contemplation on personal health, however, participation could raise sensitive issues that needed to be dealt with by skilled facilitators. Motivations for involvement differed markedly in host organisations and different strategies for marketing were adopted. The paper concludes by suggesting that while Self Care for People was both feasible and relevant to different stakeholder groups, there needs to be flexibility in responding to the needs of participants in different settings.  相似文献

Two-hundred and eighty bacterial isolates from wound and soft tissue infections were studied for species identification and antibiotic resistance pattern. Amongst them 122 isolates were from community acquired infection and 158 were from nosocomial infections. The common community acquired pathogens were Staphylococcus aureus (67.8%) and Streptococcus pyogenes (10.7%), whereas Staphylococcus aureus (60.1%) and E. Coli (8.9%) were common in nosocomial infection. Only two anaerobes (Cl perfringens) were isolated. Penicillin resistance was found to be 87% and 92% for Staphylococccus aureus in community acquired and noscomial infections respectively. 85% of Proteus isolates were resistant to ampicillin. There was relatively lower level of resistance by all isolates to cefotaxime. Gentamicin showed higher rate of resistance than netilmicin and amikacin. Resistance of E. coli isolates to fluoroquinolones being 79% for norfloxacin, 81% for ciprofloxacin and 60% for ofloxacin. The study showed a higher resistance of methicillin resistant Staphylococcus aureus (MRSA) to other antibiotics. Amikacin and ofloxacin were the best recommended drugs for empirical therapy for all organisms, the susceptibility rate being 80.7% and 80.4%.KEY WORDS: Antibiotic resistance, Soft tissue infections, Wound infections  相似文献

The focus of this article is the life and work of the French thinker Michel de Certeau, here presented as a philosopher of special interest for nursing. Although in some countries he is relatively unknown, international authors from scientific disciplines regard his texts as a fundamental source in the opening of new intellectual perspectives on current global problems. Some nurses have also considered his ideas as a useful aid for reflecting on their professional activities, and their most important research is cited. Over these pages, we also examine how Certeau's work can enrich nursing philosophy in regard to three specific issues: resistance practices in nursing in the face of pressure from health institutions; the social configuration of nursing knowledge; and the importance of the body in current nursing practice.  相似文献

Due to an increasingly ageing population, the Japanese government has promoted elderly deaths in aged care facilities. However, existing facilities were not designed to provide resident end‐of‐life care and the proportion of aged care facility deaths is currently less than 10%. Consequently, the present review evaluated the factors that promote aged care facility resident deaths in Japan from individual‐ and facility‐level perspectives to exploring factors associated with increased resident deaths. To achieve this, MEDLINE, CINAHL, Web of Science and Ichushi databases were searched on 23 January 2016. Influential factors were reviewed for two healthcare services (insourcing and outsourcing facilities) as well as external healthcare agencies operating outside facilities. Of the original 2324 studies retrieved, 42 were included in analysis. Of these studies, five focused on insourcing, two on outsourcing, seven on external agencies and observed facility/agency‐level factors. The other 28 studies identified individual‐level factors related to death in aged care facilities. The present review found that at both facility and individual levels, in‐facility resident deaths were associated with healthcare service provision, confirmation of resident/family end‐of‐life care preference and staff education. Additionally, while outsourcing facilities did not require employment of physicians/nursing staff to accommodate resident death, these facilities required visits by physicians and nursing staff from external healthcare agencies as well as residents' healthcare input. This review also found few studies examining outsourcing facilities. The number of healthcare outsourcing facilities is rapidly increasing as a result of the Japanese government's new tax incentives. Consequently, there may be an increase in elderly deaths in outsourcing healthcare facilities. Accordingly, it is necessary to identify the factors associated with residents' deaths at outsourcing facilities.  相似文献

The ‘good death’ is one objective of palliative care, with many ‘good death’ viewpoints and research findings reflecting the urban voice. Rural areas are distinct and need special consideration. This scoping review identified and charted current research knowledge on the ‘good’ rural death through the perspectives of rural residents, including rural patients with a life‐limiting illness, to identify evidence and gaps in the literature for future studies. A comprehensive literature search of English language articles (no date filter applied) was conducted in 2016 (2 January to 14 February) using five library databases. Reference lists of included articles, recent issues of eight relevant journals and three grey literature databases were also hand‐searched. Twenty articles (for 17 studies and one systematic review) were identified after a two‐phase screening process by two reviewers, using pre‐determined inclusion criteria. Data from each study were extracted and charted, analysed using a thematic analysis of the included articles' content, and with a quantitative analysis of the scoping review. These papers revealed data collected from rural patients with a life‐limiting illness and family caregivers, rural healthcare providers, the wider rural community, rural community leaders and rural health administrators and policy makers. Rural locations were heterogeneous. Residents from developed and developing countries believe a ‘good death’ is one that is peaceful, free of pain and without suffering; however, this is subjective and priorities are based on personal, cultural, social and religious perspectives. Currently, there is insufficient data to generalise rural residents' perspectives and what it means for them to die well. Given the extreme importance of a ‘good death’, there is a need for further studies to elicit rural patient and family caregiver perspectives.  相似文献
