This paper presents the methodological approach and research methods chosen to explore psychosocial aspects of participation in early anti-cancer drug trials from the perspective of those actually involved. The paper describes how an appropriate methodology, or principles of reasoning behind the choice of research methods, emerged. The choice of methodology was based on three elements: first, an understanding of the competing philosophies about how research can be approached and conducted; second, the author's view of the subject area; and third, a consideration of previous research approaches which have investigated psychosocial aspects of cancer clinical trials. A qualitative methodology situated within an interpretative paradigm was eventually chosen as the most appropriate means of exploring trial participants' experiences and the aim and objectives of the research were developed within this methodological framework.  相似文献

Stress and the intensive care patient: perceptions of patients and nurses   总被引:1,自引:0,他引:1  
This study was a replication of an earlier Cochran & Ganong study that investigated the perception of nurses and patients regarding the stressors faced by patients in the intensive care unit environment. As the original study was American in origin, one of the aims of the present study was to discover if the results would be replicated in a United Kingdom (UK) intensive care unit. Data collection was by the use of an environmental stress questionnaire that was an adaptation of the original data collection tool modified for use in a UK intensive care unit. The study was undertaken in two intensive care units producing a sample size of 71 patients and 71 nurses. There appears to be a wide variation in the perception of nurses and patients regarding the stress faced by patients in the intensive care unit. Similarities were noted between subject groups as to the nature of the stressors, although nurses tended to rate items over which they believed they had control as being more stressful than did the patients. Patients tended to rate items related to their illness and physical comfort as being most stressful. The results are in keeping with those from the Cochran & Ganong study.  相似文献

The findings from a Florence Nightingale Scholarship to the USA and Canada, investigating the educational preparation of advanced practice nurses, are reported. The author considers a number of issues facing curriculum designers who might wish to develop clinically based advanced practice nurse programmes in the UK. Utilizing the experiential nature of personal visits, along with the available literature, the strategy adopted by some American and Canadian universities is highlighted to exemplify curriculum issues likely to be encountered in the UK. A definition of advanced nursing practice is provided as a foundation for discussion on curricular construction. This is followed by a discussion on advanced role nomenclature and components and characteristics of the 'nurse practitioner', 'clinical nurse specialist', 'nurse consultant' and 'nurse clinician', in order to clarify terminology and disentangle different advanced practice roles. The issues examined include the academic level of advanced practice nurse programmes; the determination of curricular content based on both a 'generalist' and 'specialist' model of practice; factors considered when exploring advanced practice competencies; and the resource implications for delivering opposing curriculum models. The paper suggests that there is a unique opportunity for advanced practice nursing to establish a key collaborative relationship in the delivery of health care, based on a nursing model, graduate study and the integration of key nursing and related concepts into clinical practice.  相似文献

I led a party of British nurses on an Interchange of London study tour of Moscow and Leningrad early in 1986. The limitations inherent in a short tour, in which the visits were strictly organized by our hosts, are appreciated, but the party was able to visit examples of the three main institutions of care in which Soviet nurses work and to spend two evenings in informal discussion with nursing personnel. The interpretation of findings is my own and does not necessarily assume complete objectivity. Nevertheless, I have attempted to discuss data dispassionately and feel that information obtained is relevant and interesting in its own right. I have no doubt that we were shown the very best of Soviet nursing and health care, and no claims are made as to how representative the particular polyclinic, ambulance center, and hospital visited are of those in the USSR as a whole.  相似文献

The changing academic role of the nurse teacher in the United Kingdom   总被引:1,自引:0,他引:1  
This paper presents findings from a national study conducted over a 3-year period (1991–94) which examined the changing role of the nurse teacher The study used multiple methods to collect data from a wide variety of respondents (nurse teachers, midwife teachers, clinical nurses, health service managers and higher education lecturers) This paper presents the findings relating to the development of the nurse teacher's academic role following the introduction of Project 2000 The issues presented and discussed include specialization within the nurse teacher's role, the nature of this specialization and the development of academic credibility and scholarship The implications of these changes in terms of the development of nursing as an academic subject area and the opportunity to contribute to the establishment of research based practice are explored  相似文献
