Background/aim: Parkinson's disease is a progressive neurodegenerative disorder resulting in significant disability. We examined how Parkinson's disease affects daily living from the perspective of both patients and relatives.
Methods: Qualitative interviews were performed with seven patients with Parkinson's disease and nine relatives from families other than those of the interviewed patients. Patients and relatives were recruited from an outpatient geriatric unit at a university hospital in Sweden. The interviews were transcribed and analysed qualitatively.
Results: A conceptual framework encompassing aggravating factors, consequences in daily living and facilitating factors is presented. Patients perceived activity restrictions, changed habits, decreased socialisation and anxiety. Relatives reported changed roles and habits, decreased socialisation, strain and anxiety about the future. Facilitating factors included accessibility, strategies and psychological support for both patients and relatives.
Conclusions: The results show that Parkinson's disease affects daily living not only for patients but also for relatives. They need to be seen, heard and supported in this burden. Services must be adapted to the needs of both patients and relatives with accessibility to health-care facilities with deep knowledge about the disease and its consequences. The identified factors are areas of concern in occupational therapy. 相似文献

Within policy and practice there is an increasing interest in the care of frail elders. However understanding of the experience and challenges of living and dying with frailty in older age is currently undeveloped. Frailty is often used as a synonym for the increasing infirmities that accompany ageing and the slow dwindling dying trajectory of many elders. However, there is little empirical work on the experience of being frail to inform social gerontological perspectives and welfare provision. Through analysis of repeated in-depth interviews over 17 months (2006-2008) with 17 frail elders living at home in the U.K., key factors that shape elders' experience of being frail emerged. The study argues that the visible markers of functional limitations and the increasing social losses of old age bring finitude to the fore. To retain anchorage in this state of imbalance, frail elders work actively to develop and sustain connections to their physical environment, routines and social networks. This experience can be conceptualised as persistent liminality; a state of imbalance "betwixt and between" active living and clinically recognised dying. This paper highlights the precarious and often protracted dying trajectory of frail older people. Whilst it could be argued that developing into death in older age is part of a normal and successful course after a life long-lived, recognition of and support for older people deemed frail is lacking. Frail elders find themselves living in the margin between the Third and Fourth Age with little recognition of or support for the work of living and dying over time. This experience of frailty contests dominant cultural and welfare practices and policy frameworks that operate in binary modes: social or health; independent or dependent; living or dying. 相似文献

临床路径在胆囊结石腹腔镜胆囊切除术患者中应用的效果分析与探讨 总被引:2,自引:0,他引:2
目的评价临床路径应用于胆囊结石腹腔镜胆囊切除术的效果。方法调取2008年3月-2009年1月我院胆囊结石腹腔镜胆囊切除术患者的信息.以其平均住院天数、平均住院费用和满意率等作为评价指标,将路径组和对照组进行对比分析,并进行深入探讨。结果应用临床路径的患者与未应用这一方式的患者之间在平均住院时间、平均住院费用、患者满意率等方面有统计学显著差异。结论临床路径应用于胆囊结石腹腔镜胆囊切除术,可以明显缩短平均住院天数,降低住院费用。提高患者满意度。 相似文献

安徽农村不同居住环境对慢阻肺患病率的影响 总被引:17,自引:0,他引:17
目的 研究安徽省农村居民居住环境的不同及室内空气污染与慢阻肺(COPD)患病率的关系。方法 采用整群随机抽样方法,抽取安徽省安庆市3个地区21648例≥15岁的常住农村居民为调查对象,进行生活暴露的流行病学调查。结果 安徽省农村居民COPD患病率为2.13%,男性为3.16%,女性为1.37%;居住土坯平房、土坯地、土坯壁的居民COPD患病率明显高于其他居住环境的居民(P<0.01);冬日取暖时间较长、且取暖时无烟囱者,COPD的患病率明显高于不取暖者(P<0.01);饮用塘沟渠水和暴露井水的居民COPD患病率较高,患COPD的危险性是饮自来水用户的7.27倍和7.12倍。结论 安徽省农村居民的COPD患病率较国内其它城市患病率低,居住情况对COPD患病率的影响主要与取暖赞成的污染有关,尤其是取暖月份长短存在剂量反应关系;同时居住条件差,居室小环境的灰尘污染也可引起COPD的发生,提示今后应提倡改造炉灶和取暖条件,加强COPD的预防工作。 相似文献
