Evidence-Based Practice: Systems Theory and Diffusion of Innovation Theories to Healthcare Delivery and Nursing Practice
The ability to acquire accurate and timely information enhances nursing practice and patient outcomes. Search engines and healthcare nursing databases operate in different ways, and it is necessary for healthcare professionals to understand how to access and efficiently use both public and professional resources. Because today the public has greater access to electronic health information, healthcare professionals must be aware of the information their patients are accessing and be proficient at identifying credible sources. It is important for healthcare professionals to know how to use professional databases. Nursing practice needs to be based on evidence and access to healthcare databases assist nurses in identifying best practices. The use of theories from other disciplines also expands the breadth and depth of knowledge available to guide healthcare delivery and nursing practice. relating systems and diffusion of innovation theories to healthcare delivery and nursing practice. This work will discuss the relationship between systems theory and healthcare delivery in the United States and will discuss the relationship between diffusion of innovation theory and the change process within healthcare delivery in the United States. This work will additionally discuss the relationship between systems theory and current nursing practice. Finally, this work will summarize the search strategies used to acquire information on the specified theories.
The work of Laszlo...
Since social and psychological phenomena tend to resist quantitative modeling by posing basic difficulties already on the plane of boundary identification, alternative approaches must be relied upon. One such approach draws on the body of knowledge derived from General System Theory and its application in the domain of human activity systems." (p.2)
Additionally stated by Laszlo and Krippner (1998) is the fact that the history of systems theories is inclusive of "contributions from such seminal thinkers as Alfred North Whitehead, Ludwig von Bertalanffy, Anatol Rapoport, Kenneth Boulding, Paul A.Weiss, Ralph Gerard, Kurt Lewin, Roy R. Grinker, William Gray, Nicolas Rizzo, Karl Menninger, Silvano Arieti, and, in more recent years, the dynamical systems theorists, the family systems theorists, and those who deal with dissipative structures and holistic paradigms." (p.2) It reported that evidence-based practice "Is an essential principle in nursing education and practice. Leading nursing organizations recommend evidence-based practice in all aspects of education and patient care services." (Laszlo and Krippner, 1998, p.1)
Systems theory is reported to have developed from "historical ideas." (Laszlo and Krippner, 1998, p.1) Specifically, in the early 1900s Ludwig von Bertalanffy, a renowned philosopher and theoretic biologist is reported to have "modernized the significance of general systems theory. The phenomenon functions it is reported to "unlock conceptual thinking" based on the idea that all levels of an organism, whether living or environmental "comprise a logical homology that should be studied as an organized whole." (Laszlo and Krippner, 1998, p.1) In the field of health care delivery, it is reported that systems theory affects the "patterns of care, policies, and practices to influence a change in the whole organization." (Laszlo and Krippner, 1998, p.1)
It is reported that Hatcher & Heetebry (2004) utilized systems theory…
Evidence-Based Practice There is a lot of talk about evidence-based practice in the medical community, and it may seem as though it is being overstated. However, that is definitely not the case. Evidence-based practice is very important in order to make sure healthcare outcomes are the best they can be. Any problematic outcomes can be improved through the use of scholarly inquiry and analysis. Being able to analyze issues properly and

The five areas of research, background information, literature review, methodology discussion, data analysis, and conclusion in the journal article. Areas of Research Report Issues Addressed The researchers used information from previous studies like Treacy & Hyde, 2003 to create background for the
Evidence-Based Practice (EBP) is the assimilation of the best research evidence with clinical proficiency and patient values. This takes into account placing equal emphasis on the situation of the patient, his or her goals, objectives, values and aspirations, the best accessible research evidence and the clinical proficiency and expertise of the practitioner. Evidence-based practice in psychology can be defined as the incorporation and assimilation of the best accessible research with

Janvnbakht, Hejazi, & Ghasemi (2009) have clearly identified the purpose of their study. They have also stated the importance and relevance of the research topic to the current evidence-based practice. An already diagnosed illness of anxiety and depression is included in the study and evaluation of the history of other psychiatric illness confirmed before the study.

Evidence-based practice is an approach that has been applied to clinical practice and nursing. Evidence-based practice started initially in medicine and went to fields like education, psychology, nursing and dentistry. It should be noted that the research is based on studies that were carried out and these studies go on to fit the scenario that is currently being dealt with. Treatments that are supported empirically are the ones that are proven
