We report the use of ethanol lock therapy to dramatically reduce the incidence of catheter‐related bloodstream infections (CRBSIs) in a long‐term adult home parenteral nutrition (HPN) patient. This case study demonstrates the efficacy of ethanol lock therapy in eliminating CRBSIs when other treatments have been unsuccessful. We suggest that ethanol lock therapy has an important role in decreasing CRBSI in HPN patients with recurrent CRBSIs.  相似文献

Background Socioeconomically deprived women are at greater risk of adverse pregnancy outcomes. Research tends to focus on access of services. Yet access may not equate with the equity of services for women from different socioeconomic backgrounds. Objectives To determine whether pregnant women’s perceptions of antenatal provision differed in relation to their socioeconomic deprivation ranking (determined by the Scottish Index of Multiple Deprivation 2006). Design A longitudinal, qualitative study with comparative antenatal case studies between January 2007 and April 2009. Setting/Participants Cases were primigravida women from ‘least deprived’ (n = 9) and ‘most deprived’ (n = 12) geographical areas within one local authority in Scotland. Analysis Data were analysed using case study replication analysis. Results There was little difference in access to antenatal services between the ‘least’ and ‘most’ deprived groups. Perception of care differed in relation to the level of ‘engagement’ (defined using constructs of: language and personalization of care; power and relationships; and health literacy). Engagement was evidenced in most of the ‘least deprived’ cases and almost none of the ‘most deprived’ cases. Specifically, socioeconomically deprived women described less evidence of personal connection to their own care, effective communication and the opportunity for shared decision making. Conclusion In women from socioeconomically deprived areas, access may be a less useful indicator than engagement when assessing antenatal service quality. As engagement levels may be one method by which to predict and improve health outcomes, a more equitable antenatal service may need to be developed through the early identification of those women at risk of non‐engagement.  相似文献

The purpose of this study was to explore the perceived needs and anxiety levels of adult family members of intensive care unit (ICU) patients. The study was conducted over a 3-month period, on a convenience sample of 166 subjects selected from the total adult population of family members visiting an ICU patient in three Sudbury hospitals. Data were gathered using a self-report questionnaire, the Critical Care Family Needs Inventory (CCFNI) and Spielberger's State Trait Anxiety Inventory (STAI). Interviews were conducted in French or English according to the subject's preference. The major variables examined were: family needs; state and trait anxiety; on-site sources of worry; spiritual needs; level of knowledge of ICU from past experience or pre-surgery education; sociodemographic data. The Situational Anxiety Scale yielded a mean score of 45.24 and the Trait Anxiety Scale a mean score of 37.3. Inferential statistics demonstrated that family needs and situational anxiety were significantly related (P less than 0.0002). Furthermore, worries, trait anxiety, age and family needs explained 38% of the variation of situational anxiety. As well, spiritual needs and situational anxiety explained 33% of the variation of family needs.  相似文献

The purpose of this study was to describe the amount of congruence in the perceptions of 38 matched nurse-patient dyads concerning the nurse's role in patient education. The perceptions of nurses and patients from two hospital settings were measured with two complementary sets of questions, developed for this study; t-tests were used to compare the mean responses of nurses and patients within and between the two settings to each set of complementary questions. The results indicated that incongruencies existed between nurses' and patients' perceptions of the nurse's role in patient education. Patients identified a general teaching function for nurses. When asked who they preferred to have teach them the specific information related to their condition, patients most frequently chose a physician. Nurses most frequently chose a nurse as the current and most desired patient teacher. Nurses incorrectly assumed that the desires of their patients for patient education were similar to their own. The results suggest that nurses need to develop a clear definition of their role in patient education, to validate patients' desires for teaching, and to examine organizational factors influencing their performance of the patient teaching role.  相似文献

Florence Nightingale, feminism and nursing   总被引:1,自引:0,他引:1  
Three key aspects of Florence Nightingale's remarkable life are examined. First, the influences during her formative years: the education and guidance provided by her father, the resistance by her family when she decided to become a nurse; and the rejection by Nightingale of the societal expectations of a woman in the Victorian era. Secondly, her professional life is examined, in particular how she appears to have been viewed by certain members of society, and how in turn she viewed them. It is anticipated that her position as an early feminist will be postulated and illuminated. Thirdly, an analysis of her personal and professional life indicates a way forward for the nursing profession.  相似文献

There are many dysfunctional manifestations relative to the tenure and promotion process. These are disruptive to academic life. Much of this is encouraged by the university because of their publish or perish ethic. Excellence in classroom teaching and success in the field of clinical and human endeavours are not highly valued in deliberations to grant tenure and advancement in academic rank. Research and publications are the major yardsticks upon which a faculty member is judged. This prevailing perspective poses a dilemma for many nursing faculty who have high clinical workloads and have not been socialized for academic survival. The pressures to publish and research can be achieved in a realistic and non-stressful way. Three aspects seem to be particularly relevant to facilitate this achievement; these are: anticipatory planning, balancing the workload, and understanding the interpersonal dimensions of collegeality.  相似文献
