== Barriers to promoting evidence-based practice ==
The use of evidence-based practice depends a great deal on the nursing student's proficiency at understanding and critiquing the research articles and the associated literature that will be presented to them in the clinical setting.  According to, Blythe Royal, author of Promoting Research Utilization in nursing:  The Role of the Individual, Organization, and Environment, a large amount of the preparation requirements of nursing students consists of creating care plans for patients, covering in depth processes of pathophysiology, and retaining the complex information of pharmacology.  These are indeed very important for the future of patient care, but their knowledge must consist of more when they begin to practice.  Evidence-based nursing in an attempt to facilitate the management of the growing literature and technology accessible to healthcare providers that can potentially improve patient care and their outcomes.  Nancy Dickenson-Hazard states, "Nurses have the capacity to serve as caregivers and change agents in creating and implementing community and population-focused health systems." There is also a need to overcome the barriers to encourage the use of research by new graduates in an attempt to ensure familiarity with the process. This will help nurses to feel more confident and be more willing to engage in evidence-based nursing. A survey that was established by the Honor Society of Nursing and completed by registered nurses proved that 69% have only a low to moderate knowledge of EBP and half of those that responded did not feel sure of the steps in the process.  Many responded, "lack of time during their shift is the primary challenge to researching and applying EBP."  There is always and will always be a desire to improve the care of our patients.  The ever-increasing cost of healthcare and the need for more accuracy in the field proves a cycle in need of evidence-based healthcare.  The necessity to overcome the current issues is to gain knowledge from a variety of literature not just the basics.  There is a definite need for nurses, and all practitioners, to have an open mind when dealing with the modern inventions of the future because these could potentially improve the health of patients.
There are many barriers to promoting evidence-based practice. The first of which would be the practitioner's ability to critically appraise research. This includes having a considerable amount of research evaluation skills, access to journals, and clinic/hospital support to spend time on EBN. Time, workload pressures, and competing priorities can impede research and development. The causes of these barriers include nurses' and other professional practitioners' lack of knowledge of research methods, lack of support from professional colleagues and organizations, and lack of confidence and authority in the research arena.
Another barrier is that the practice environment can be resistant to changing tried and true conventional methods of practice. This can be caused because of reluctance to believe results of research study over safe, traditional practices, cost of adopting new practices, or gaining momentum to rewrite existing protocols. It is important to show nurses who may be resistant to changes in nursing practice the benefits that nurses, their patients, and their institutions can reap from the implementation of evidence-based nursing practice, which is to provide better nursing care. Values, resources and evidence are the three factors that influence decision-making with regard to health care. All registered nurses and health care professionals should be taught to read and critically interpret research and know where to find articles which relate to their field of care. In addition, nurses need to be more aware of how to assess the information and determine its applicability to their practice.
Another barrier to implementing EBN into practice is lack of continuing education programs.  Practices do not have the means to provide workshops to teach new skills due to lack of funding, staff, and time; therefore, the research may be tossed dismissed.  If this occurs, valuable treatments may never be utilized in patient care.  Not only will the patients suffer but the staff will not have the opportunity to learn a new skill.  Also, the practitioners may not be willing to implement change regardless of the benefits to patient care.
Another barrier to introducing newly learned methods for improving treatments or patients' health is the fear of "stepping on one's toes".  New nurses might feel it is not their place to suggest or even tell a superior nurse that newer, more efficient methods and/or practices are available.
Even if clinicians do act consistently it is possible that their decisions are consistently biased.  People put different values on gains and losses. Tversky and Kahneman gave people the two identical problems (with the same probabilities of life and death outcomes – see fig 1) but framed the outcome choices as either lives saved or as deaths.10 Most people wanted to avoid taking risks with gains which could be safeguarded, but would take risks with losses which might be avoided; this is a framing effect. If people are given identical options but different words are used to emphasize a gain rather than a loss, then a different response is given by a large proportion of the population under study. Such a change in response appears to be inconsistent.

== Implementation and sustainability ==
The Iowa Model is used to promote quality of care. It is a guideline for nurses in their decision-making process. The decision making can include clinical and administration practices. These practices affect patient outcomes. The model is based on problem-solving steps that are a part of the scientific process. Recognition for applicability and ease of use. Key components of using the Iowa Model:
