Literature Review of the application of evidence – based practice.
Nutrition (Renal diet) in Chronic Kidney Disease
Aim of the Assessment
The aim of this assessment is to enable you to demonstrate your ability to review the application of evidenced based and evidence informed practice using three chosen pieces of literature in relation to a subject area of interest within healthcare.
This assignment addresses the following learning outcomes:
Demonstrate an understanding of the context of evidence-informed practise with particular reference to distinct fields of practice, professional practice, public health policy and person-centred care
Critically analyse the application of the hierarchies of evidence with clinical guidelines relevant to specific fields of nursing
Critically review the key steps in research design, including an understanding of underlying philosophies and the application of appropriate methodologies to different clinically-based research questions.
Select and retrieve two peer reviewed primary research articles related to an area of patient care within the last five years and link your findings to one corresponding current NICE guidance document
Presentation
The assignment should be presented as a literature review using the following structure:
Introduction and background (500 words)
An outline of the nature of the chosen subject area and the critical issues concerning practice must be presented. There may be numerous issues within the paper, e.g. the care episode, condition, treatment, or intervention.
Focus on one aspect and think about one question relating to the articles that you would like to be able to answer, in order to provide a summary aimed at the public with no medical background (CW2). This must be relevant to nursing practice.
Provide some background information on the subject area that you have chosen with a rationale for your choice using a range of appropriate supporting evidence.
Question Formulation and Search process (500 words)
The search strategy used must be exact; document your search strategy in a labelled table. Use tables and figures where appropriate to reduce the word count .
The reader should be able to replicate your search using the information given and must include the following:
Explain how you arrived at your questions including the use of SPICE, PICO or alternative to formulate the question
Discuss which databases and other sources you used to find evidence, including the keywords or search terms, and how you selected them.
Discuss how you refined your search and the parameters you used, for example, inclusion and exclusion criteria such as dates or other criteria with justification for all your decisions.
Include a copy of your searches in an appendix.
Include a completed copy of the CASP checklist/s used as an appendix.
Critical Appraisal of Evidence (800 words)
Reference the two primary research studies that you have chosen (author/date) in the text at least once, and you must include the reviewed article in the reference list.
You must use research theory (textbooks) and include in-text references (academic journals) to support your discussion of the strengths, weaknesses and limitations of the research design.
Make use of appropriate published critiquing frameworks to help structure your appraisal, for example, the CASP Tool available at https://joannabriggs.org/criticalappraisal-tools.
The following aspects of each paper should be appraised:
Study design
Sampling
Ethical issues
Data collection
Data Analysis
Conclusions made in the study
Validity/authenticity/credibility/transferability
Again, tables or a matrix can be used to summarise the appraisal- Use the appendix for this additional information
Presentation of the key themes- A brief summary of the key themes from the two papers should conclude this section.
Discussion (800 words)
Critically evaluate the themes identified in your papers
Reflect on the key messages of the selected primary research studies and whether they could be of use in practice. If not, why? Critically discuss the “fit” with the NICE guideline that you have chosen in addressing your question and consider
The links between the primary research papers and the NICE guidance
The dates of the publication of the papers and the NICE guidance and the impact of this
Discuss whether the evidence from the primary research papers signals a need to review the NICE guidance
This part should continue to demonstrate analysis and arguments and should be supported with references
Conclusion (400 words approx.)
Summarise key points from the entire assignment (do not merely re-iterate findings from the studies reviewed) explaining how this meets learning outcomes 1-3
