In this essay, I am going to consider how evidence-based practice can be used to support, justify, legitimate and/or improve clinical practice. I am also going to explore and discuss primary and secondary research evidences about how nursing interventions can potentially improve the quality of life of patients in the community suffering from heart failure. I will gather these evidences using a literature search which I will include an account of. Using a critiquing framework for support, I will appraise both primary and secondary evidences that I have chosen. I will also look at potential non-evidential factors that can influence evidence utilisation in practice. Finally, a conclusion will be drawn.
Evidence-based Practice (EBP) is

This is a randomised controlled trial (RCT) which according to Guyatt et al’s (2000) approach to grading research, as having the highest level of evidence based on the method’s effectiveness. However, Evans (2003) argued that focusing solely on effectiveness of a piece of research, while this is clearly vital, it is equally important to look at appropriateness and the feasibility of the research. Appropriateness emphasises the psychosocial aspects of the research; while feasibility underlines matter associated implementation, cost and practice change. Using these 3 measurements, Evans (2003) still placed RCTs in the higher platform of the evidence hierarchy. This research’s method can determine the cause-effect relationship of the intervention and its potential outcomes (Morrow, 2008) which fits to its aims. This proves that this research is appropriate to its targeted sample. But, there is still the issue of costs and problems concerning practice change. This regards to the provision of training and time for nurses to carry out the interviews. If this research is able to provide quality results, then it can be forwarded to managers to be implemented but there is no warranty to it.
The recruitment method of this research was quite vigorous in terms of the criteria for eligibility. It is justified by the researchers’ precise aim and their focus to the trial intervention and the
