Student nurses have the responsibility of assessing the relationship of evidence to practice whether it is in the clinical or the community setting. In order to achieve this, the student nurse has to conduct thorough research and evidence-based practice in the different EBP interventions applied by organizations. This paper shall assess such evidence-based practices applied by various institutions and in the process appraise two pieces of evidence relevant to my area of interest. After the development of two in-depth critiques, the usefulness of this evidence in practice shall be evaluated. The principles of evidence based practice shall also be evaluated through a discussion of the different types of evidence, levels of evidence and the importance of evidence for practice.
Evidence-based practice is the act of connecting what the population needs with the most updated and the best evidence possible based on scientific studies; its purpose is to evaluate what would be effective and to utilize studies while considering community resources, values, and preferences in order to improve the health of the general population (Queensland Government, 2006, p. 1). In various fields of practice and even the law, evidence refers to materials which can support or refute a current issue. In healthcare, evidence based practice emphasizes the independent verification and observation of a practice before it can find application. “This does not presuppose the value of a particular evidence source or study design over another, but instead highlights the importance of ensuring that the evidence used to inform practice (and policy) has been subject to scrutiny” (Rycroft-Malone, et.al.,2004, p. 82). There are different sources of evidence which may be applied in evidence-based practice. The two main sources are through the use of the quantitative and the qualitative research methods. Qualitative research basically investigates the essential
