It was hypothesized that there would be no significant difference in the quality of care, or the level of client satisfaction, provided by the medical officers and the nurse practitioners in the study. Two groups participated in the study, nurse practitioners and medical officers. The study used a randomized trial design. Data were collected using quantitative and qualitative methods. Two hundred and thirty-two clients participated in the study. Of this number 63 were supervized cases in the pilot trial. In the randomized trial participants were distributed between nurse practitioners and medical officers (n = 169), of which 91 were randomized to medical officers and 78 to nurse practitioners. Telephone interviews were conducted to evaluate client satisfaction. The majority of study participants were surveyed for client satisfaction (n = 132). This represents approximately 78% of the randomized sample and multivariate analysis was carried out on the data. Study results indicate that there were no significant differences between the two groups in relation to client satisfaction. Very positive outcomes of treatment were consistent across groups in the study. The study also found that there was strong support for the role of the nurse practitioner in the rural emergency setting. Recommendations include further research to measure the efficacy of nurse practitioners utilizing the selected competencies in remote/isolated settings.

Computerized databases were searched as well as hand searching of articles in order to conduct this review. This review identified multiple factors related to the experience of role stress in nurses. Role stress, in particular, work overload, has been reported as one of the main reasons for nurses leaving the workforce. This paper concludes that it is a priority to find new and innovative ways of supporting nurses in their experience of role stress. Some examples discussed in this article include use of stress education and management strategies; team-building strategies; balancing priorities; enhancing social and peer support; flexibility in work hours; protocols to deal with violence; and retention and attraction of nursing staff strategies. These strategies need to be empirically evaluated for their efficacy in reducing role stress.

Stress detrimentally can influence job satisfaction, psychological well-being, and physical health. There is a need for increased understanding of the stress that nurses experience and how best to manage it. Three hundred twenty Australian acute care public hospital nurses participated in a study by completing four questionnaires that examined (a) how various workplace stressors relate to ways of coping, demographic characteristics, and physical and mental health and (b) which workplace stressors, coping mechanisms, and demographic characteristics were the best predictors of physical and mental health. Significant correlations were found between stressors and physical and mental health. Multiple regression showed age to be the only significant predictor of physical health. The best coping predictors of mental health were escape–avoidance, distancing, and self-control. Other significant predictors of mental health were support in the workplace, the number of years worked in the unit, and workload. Mental health scores were higher for nurses working more years in the unit and for those who used distancing as a way of coping. Mental health scores were lower for nurses who used escape–avoidance, lacked workplace support, had high workload, and used self-control coping. The findings have implications for organizational management, particularly in terms of recommendations for stress management, social support, and workload reduction.

Adherence to these programs is an even bigger problem, with only about one third maintaining attendance in these programs after 6 months. This review summarizes research that has investigated barriers to participation and adherence to CR programs. Some consistent factors found to be associated with participation in CR programs include lack of referral by physicians, associated illness, specific cardiac diagnoses, reimbursement, self-efficacy, perceived benefits of CR, distance and transportation, self-concept, self-motivation, family composition, social support, self-esteem, and occupation. Factors associated with non-adherence include being older, female gender, having fewer years of formal education, perceiving the benefits of CR, having angina, and being less physically active during leisure time. However, many of the studies have methodologic flaws, with very few controlled, randomized studies, making the findings tentative. Problems in objectively measuring adherence to unstructured, non-hospital-based programs, which are an increasingly popular alternative to traditional programs, are discussed. Suggestions for reducing barriers to participation and adherence to CR programs, as well as for future research aimed at clearly identifying these barriers, are discussed.

It included two groups of participants, one which identified as rural and another which identified as remote. The findings for the rural cohort in the study are presented in this article. Research participants represented a national sample. The Delphi method was used to obtain the most reliable consensus of the nurse participants. In the final phase of the study, 13 high priorities were identified. Study findings highlight perceived needs for clinical nursing research and continuing education for nurses practising in rural Australia.

Nursing science lacks well-evaluated interventions to address the specific rehabilitative needs of older women with heart disease. This paper seeks to inform the development of nursing intervention studies by a review of published studies on the experiences and rehabilitative needs of older women with heart disease. The CINAHL, MEDLINE, FAMILY and PsychINFO databases were searched, identifying literature published from 1982 and written in English. Keywords used were women, old* (old, older) women, elderly women and: heart disease, heart failure, cardiac and rehabilitation. Hand searching of nursing and medical textbooks also occurred. These searches resulted in over 120 articles that met the criteria of describing experiences, perceptions, psychological responses and support rehabilitative needs of older women. Older women present with symptoms that are different from those derived from a male-dominated research agenda and further there is a paucity of data related to evaluation of interventions tailored to the needs of women. Key themes emerging from the literature review include not only that older women compared with men have a poorer prognosis and experience greater disability moreover they: (1). are at a higher risk of psychosocial distress; (2). have a greater need for instrumental support and social support; (3). have an altered perception of risk; and (4). demonstrate the need for specific rehabilitation programs, tailored to their needs. Future research should develop and evaluate intervention studies that better meet the unique needs of older women with heart disease. Particular emphasis needs to be on psychosocial aspects, given evidence that identify these are major concerns for women.

The purpose of the present study was to examine sources of, and changes in, role stress 2-3 months after employment, and 11-12 months later in new graduate nurses. This study also investigated the relationship between job satisfaction and role stress. A factor analysis demonstrated that role ambiguity was the most salient feature of role stress in the first few months, while 10 months later, role overload was the most important factor explaining variance in role stress scores. There was no significant change in role stress scores over time. For the first survey, job satisfaction was significantly negatively correlated with role ambiguity and role stress. In the second survey there was still a significant negative correlation between role ambiguity and job satisfaction, but no significant correlation between role overload and job satisfaction. The findings are discussed in terms of implications for nursing education, practice and future research.
