ContextIt is especially important that patients are well informed when making high-stakes, preference-sensitive decisions like those on the Physician Orders for Life-Sustaining Treatment (POLST) form. However, there is currently no way to easily evaluate whether patients understand key concepts when making these important decisions.ObjectivesTo develop a POLST knowledge survey.MethodsExpert (n = 62) ratings of key POLST facts were used to select items for a POLST knowledge survey. The survey was administered to nursing facility residents (n = 97) and surrogate decision-makers (n = 112). A subset (n = 135) were re-administered the survey after a standardized advance care planning discussion to assess the scale's responsiveness to change.ResultsThe 19-item survey demonstrated adequate reliability (α = 0.72.). Residents' scores (x = 11.4, standard deviation 3.3) were significantly lower than surrogate scores (x = 14.7, standard deviation 2.5) (P < 0.001). Scores for both groups increased significantly after administration of a standardized advance care planning discussion (P < 0.001). Although being a surrogate, age, race, education, cognitive functioning, and health literacy were significantly associated with higher POLST Knowledge Survey scores in univariate analyses, only being a surrogate (P < 0.001) and being white (P = 0.028) remained significantly associated with higher scores in multivariate analyses.ConclusionThe 19-item POLST Knowledge Survey demonstrated adequate reliability and responsiveness to change. Findings suggest the survey could be used to identify knowledge deficits and provide targeted education to ensure adequate understanding of key clinical decisions when completing POLST.  相似文献

People with mental illness may be unable to provide critical input about the care they wish to receive during a psychiatric crisis because of altered mental states. It is therefore imperative that clinicians seek to understand service users' wishes for care while they are well and able to provide meaningful input into the discussion. Achieving such an end may be done by discussing and completing a psychiatric advance directive. However, very few Asian countries have legislation that supports such advance directives. The present article seeks to give physicians more information about advance psychiatric directives and the potential role they could play to improve the healthcare provided in Asia to people at risk of losing capacity due to a mental illness. The degree to which mental health legislation supports psychiatric advance directives is documented for each country of South East Asia and Eastern Asia.  相似文献

近年来新发现的凋亡抑制蛋白(inhibitor of apoptosis proteins,IAPs),是一类高度保守的内源性抗凋亡基因家族表达产物,广泛存在于许多物种如病毒、真核生物、哺乳动物中,起着抑制细胞凋亡的作用.IAPs主要通过抑制caspase,参与TNFR介导的信号转导等途径发挥抗凋亡作用,与恶性肿瘤、神经系统病变等密切相关.该文就IAPs的结构、抑制凋亡的机制及其在临床疾病中的研究现状作一综述.  相似文献

The impact of dementia and Alzheimer's disease extends far beyond the healthcare needs of the person with dementia. As the disease progresses, individuals with dementia often require ongoing formal or informal care for their basic daily routine because of behavior changes and continuing loss of cognitive function. Most of the care for people with dementia takes place at home, and the unpaid, informal caregivers are often spouses or other relatives. Providing long-term informal care at home for someone with dementia is psychologically, physically, and financially draining. The tragedy described in this case elucidates the far-reaching societal impact of dementia care and the implicit health policy considerations.In 2007, a 91-year-old Japanese man with dementia was in the care of his wife when he wandered from home, was hit by a train, and died, immediately affecting the Central Japan Railway Company operations and, subsequently, legal practice as well as Japanese elder care policy. The railway sued the man's wife and son for negligence and lost revenue, winning both trials at the local and district courts. This ruling shocked families and caregivers in Japan, where care for elderly parents traditionally falls on the oldest son, and brought attention to the complex issues related to dementia care. A decade later, we revisit this case to provoke a renewed dialogue about the matrix of responsibilities and liabilities associated with caregiving; to illuminate the unmet needs of the person with dementia, as well as his or her informal caregivers; and the financial implications related to long-term care policy. We close with 2 practical suggestions which preserve the dignity of the individual and provide reassurance for caregivers.  相似文献
