Evidence-Based Practice and Nursing
A growing consensus has emerged within the field of modern nursing which holds that the most effective patient care is delivered through the use of evidence-based practice (EBP) by nurses and other health care providers. Although there are several distinct models of evidence-based practice, each typified by its varying approach to research utilization, EBP has been authoritatively defined as "the integration of the best research with clinical expertise and patient values" (Sackett et al., 2000). Two of the most prevalent models of EBP throughout the nursing profession are the Iowa Model and the Star Model, and each relies on a unique philosophy regarding the factors used to guide the implementation of academic research into clinical application. Conceived by Marita G. Titler, PhD, RN, FAAN and her colleagues, the model officially known as the Iowa Model of Research-Based Practice to Promote Quality Care was "developed and originally implemented at the University of Iowa Hospitals and Clinics (UIHC)" and "serves as a guide for nurses and other health care providers to use research findings for improvement of patient care" (Titler et al., 2001). In contrast, the Star Model of Knowledge Transformation®...
By exploring the similarities and contrasts between the Iowa and Star models of EBP, including a review of the processes utilized and the outcomes produced, I intend to address how EBP may ultimately provide solutions to the nursing shortage currently crippling America's health care system.
It has been consistently demonstrated that "a professional work environment that engages and optimizes the empirical and theoretical foundations of nursing can advance patient health and safety" (Pipe, 2007) and both the Iowa and Star models advocate a thorough review of existing empirical evidence by the nursing discipline. The Iowa model employs a rigorous standard of research utilization which strives "to identify areas of clinical inquiry (problem- and knowledge-focused triggers) that may be addressed through synthesis and application…

Nursing Shortage Issues Surrounding the Nursing Shortage In the early 2000s, national strategies to improve the nursing workforce profile were largely focused on increasing the number of nurses at the bedside through the use of sign-on bonuses and travel nurses. While these strategies tended to provide local short-term solutions, they did little to address long-term issues affecting the nursing shortage. With nursing education programs challenged to increase student enrollment, many colleges were
Nursing shortages and high nurse turnover are very common issues faced in the health care industry. This instability of workforce in the health care industry in many countries is raising questions about performance of the nurses and quality of the patient care. Gray & Phillips (1996) pointed out that nursing turnover has a negative impact on the organization's ability to meet the needs of the patients and provide them quality care.
Nursing Shortage Review On Nurses Shortage The supply of professional nurses relative to the increase in demand for their services has been on a general decline over the years. As a career choice, nursing has been facing perennial shortage of professionals. Most healthcare organizations will affirm that their daunting tasks were recruiting fresh nurses and retaining the ones already in practice. The 2008 projections from the Bureau of Labor Statistics showed that
1%." (AACN, 2008) VII. Negative Affects of Nursing Shortage on Patient Care Study findings indicate that a connection exists between adequate nursing staffing and patient care and specifically state in the findings of the latest studies published in the journals of Health Services Research (August 2008) and the Journal of Nursing Administration (May 2008) are findings that confirm previous study findings linking education level and patient outcomes. This indicates that "…efforts to
Nursing Shortage The objective of this work is to research the current nursing shortage and identify two articles published in nursing journals related to the nursing shortage. One of the article should discuss approaches to resolving the shortage and the other should discuss a perspective on the recruitment and impact of foreign nurses. The implications of the information gained in this brief study of the two articles introduced at the beginning
Nursing Shortage Background and Current Reality The shortage of nursing staff in the workforce has become a global crisis. Numerous research articles and even books have been written on the subject from all around the world, all giving causal factors and possible solutions. As far back as 2002, "90 nurses' organizations, representing 69 countries and every geographic region of the world, reported shortages in their countries" (Clark & Clark, 2003). Moreover, the
