The data gathered is subjected to statistical analysis using statistical methods of linear regression and chi square testing.
The main purpose of the study was to confirm the hypothesis that consultation with CNS or RN in a drug-monitoring clinic has a significant positive impact on the well being of patients with rheumatoid arthritis. The study involved a single blinded randomized controlled trial over a period of three years. Subjects were chosen from the rheumatology out patient setting in a district general hospital with a drug monitoring service. A total of 71 subjects who were starting out on anti-rheumatic therapy were randomly assigned to either the interventional or the control group. While the interventional group was supervised by the CNS to assess patient needs (using Pendelton's framework) alongside drug safety evaluation, the control group was seen by an outpatient staff nurse purely for drug safety concerns. Both the groups were assessed periodically for their scores on the Arthritis impact measurement scales (AIMS) and Rhematology Attitude Index (RAI) as well as the Disease Activity Score. The interventional group fared well in all these indexes during the course of the study and at the endpoint. The research has definite bearings for evidence-based nursing approach and the positive outcome of the study attests that the integration of clinical practice and scientific evidence is the key to improving the quality of health care. This study has clearly shown how evidence-based nursing could optimize treatment and outcome in a hospital outpatient setting. [Ryan et al., 2006]
The clinical implications are profound. The emergence of the nurse as a specialist caregiver creates a dynamic leap in terms of improving standards across the whole spectrum of health care. Evidence-based nursing approach is a vital link in bridging the existing chasm between advancements in medical technology and healthcare delivery. This research is relevant for nurse specialists as important members of the healthcare workforce who are more and more involved in evidence-based decision-making. Ultimately the research also impacts the patients as receivers of care as evidence-based medicine is the new platform of care delivery that calls for resource optimization at every level in the healthcare setting. This research is another supporting evidence to the cause of evidence-based practice, which the hospital administration should promote. This would also give new impetus for the nursing force as evidence-based nursing would motivate nurses and increase their job satisfaction. This is particularly important at a time when hospitals are struggling with high attrition rate and nursing shortage. The success of this study could be emulated in other clinical settings. This would involve a coordinated approach from the nursing staff, doctors and the hospital administration.
All the articles reviewed in this paper expounded the crucial role of Nurses in the prevention of preventable adverse events and in improving the overall quality of care. While Considine and Botti (2004) and Pipe et.al (2005) discussed the importance of pro-active nursing practice and the implementation of evidence-based nursing approach in the clinical setting, Ryan et al. (2006) was a study which reported the success of implementing an integrated evidence-based practice system. That is, the first two articles that were reviewed were basically a literature review of several earlier studies and presented a theoretical viewpoint. The final study was the practical implementation of the evidence-based nursing care. It is clear that nurses are constrained in terms of the interventions that they could initiate. However, the fact remains that a vast majority of the nursing staff do not respond independently though the patient parameters are abnormal and critical. Time is of essence and in such situations delay resulting from waiting for interventions by senior physicians would exacerbate patients condition leading to adverse events. Besides the interventions that they could directly initiate, nurses also have the responsibility of initiating EMT action, calling for direct medical staff support and thus play a central role in the prevention of adverse events and the delivery of optimal care. The new, evolving role of the nurse is that of a proactive and evidence-based care provider. The successful implementation of this change however, would necessitate a revamp of the organizational structure and dynamics to permit smooth and effective communication and to create an environment where the nurse could participate more independently as well as in excellent coordination with other caregivers.

Nursing Theory Analysis Theory-based nursing is the phenomenon that has been researched much during the past two decades. Nursing theory has become the foundation for nursing practice with its own knowledge base. The current paper is an analysis of King's theory of goal attainment. King acquired her goal attainment theory model from an interpersonal system and a behavioral science. The nurse and patient communicate to achieve a common goal of patient

Levine got a diploma in 1944 and obtained her B.S in 1949 and finished M.S.N in 1962 from Wayne State College. She acted as a specialist to healthcare facilities and colleges of nursing. Furthermore, she offered a teaching format for the medical or surgical sector
Nurses The nursing profession has always attempted to put forward a positive, clean and healthful image. Throughout history the nursing industry has tried to portray nurses as angels of mercy, and as ethically upstanding, helpful healthcare professionals, just a few steps down from doctors in terms of medical needs. But lately the images of nurses has changed and not always for the best. This paper critiques the images of nurses
Nursing According to the Systems and Diffusion of Innovations Theories The internet and the distribution of electronic health records have changed the way the we receive and use health information but as health professionals and as patients. Particularly, public access to electronic healthcare information denotes that healthcare professionals have an added responsibility where patient education is concerned. Helping to educate patients regarding both their specific conditions as well as how best
Learning in adults is most effectual when the environment is both participative and interactive. Another important characteristic is that learners obtain instantaneous feedback. Teaching methods that necessitate a learner to think though data or information and come to a conclusion or forecast an outcome are more valuable than is reading or lecture.

While it would have been unquestionably beneficial to the patient and indeed to this nurse to be able to engage in a more meaningful, enlightened, and research-based discussion of her condition and methods for addressing it, this nurse simply did not have the time to devote to reading the latest research on diabetes care in addition to remaining prepared for all patients. The policies of the organization in which
Nursing Science The historical development of nursing science can largely be dated back to the era of Florence Nightingale. It is however imperative to note that nursing as a largely independent profession has over the past century converged into a well founded theoretical perspectives culture. In this text, I will develop a nursing science historical development timeline with a mention of specific theorists, theories, years as well as events in nursing
