This paper describes and analyses, from a sociocultural viewpoint, the ways of life of discharged long-term psychiatric patients in northern Finland The paper focuses on subjectivity control of life and fundamental experiences in life The data consist of interviews with 25 outpatients who have moved to live in residential homes, rehabilitation centres or their own homes after receiving preparatory training in the psychiatric hospital The findings suggest that the way of life of the outpatients did not significantly differ from that of other people belonging to the same generation of Finns With respect to control of life, a conspicuous feature was the strong tendency to let themselves be led by others, and to self-sacrifice for the good of others For the patients, independence was the best aspect of open care Fear for being branded as a psychiatric case or as a former mental patient threatened the patients'external control of life The central element of control of life of the Finns is work The outpatients thought work a matter of honour and they did not find their present, inactive way of life satisfactory 相似文献

Clinical practice guidelines have emerged as a reality for medical practitioners over the past 20 years. Although virtually all groups interested in the development of practice guidelines hope for improvements in patient care, secondary expectations vary widely among those using them. Their use in daily practice by physicians has met with resistance from barriers including concerns of “cookbook” medicine, a loss of autonomy, and increased professional liability. The recent experience of the ACR in addressing these challenges illustrates that physicians are receptive to steps perceived to mitigate the risks accompanying the use of guidelines as well as to efforts to increase their understanding of implementing guidelines in clinical practice. The experiences of other medical societies and an inventory of future trends reveal additional challenges associated with the use of practice guidelines, as third parties look to guidelines as points of reference for gauging the performance of health care providers. 相似文献

Background: Elder patients with acute coronary syndromes (ACS) are less likely to receive cardiac catheterization. The reasons for this are unclear.
Objectives: To assess whether elder patients who had a documented history of dementia, lived in extended care facilities, or had do not intubate–do not resuscitate (DNR-DNI) advance directives were less likely to receive cardiac catheterization, despite having ACS with high-risk features.
Methods: This was a medical record review conducted at an urban teaching hospital. DNR-DNI status before hospitalization, extended care facility (nursing home or assisted living) residence, and a previous diagnosis of dementia were obtained from the medical record. Patients 65 years and older who presented to the emergency department with acute myocardial infarction or with unstable angina with ST segment deviation were included. Univariate and multivariate logistic regression were performed, and odds ratios (ORs) were reported with their 95% confidence intervals (CIs).
Results: Of the 201 eligible patients, 66 (32.8%) patients did not undergo cardiac catheterization. In the univariate analysis, patients who had dementia, resided in extended care facilities, or were DNR-DNI were less likely to receive cardiac catheterization. Only extended care facility residence (OR, 0.18; 95% CI = 0.04 to 0.83) and DNR-DNI status (OR, 0.19; 95% CI = 0.04 to 0.92) remained significantly associated with decreased cardiac catheterization in the multivariate analysis.
Conclusions: Elder patients with ACS residing in extended care facilities or who are DNR-DNI are less likely to receive cardiac catheterization. Future studies concerning the quality of ACS care for elders should take these variables into account. 相似文献

TOPIC: Psychological impact of adoption and resulting core issues for adopted children. PURPOSE: To raise awareness of the psychological impact of adoption. SOURCES: Published literature and personal observations. CONCLUSIONS: Adoption raises unique issues and challenges for the child and adoptive parents. Resolving the issues of adoption is a lifelong process. Through an awareness of the issues inherent in adoption, nurses and parents can use strategies that will enhance children's self-esteem and decrease their emotional vulnerability. Search terms: Adoption, intervention, loss, self-esteem, strategies 相似文献

A documentation system that facilitates accurate and complete recording is needed by every obstetric/neonatal nursing service. Developing an individualized system is a major undertaking. However, specific steps can be taken to ease the process. These steps are described, beginning with the assessment phase and concluding with evaluation. 相似文献
