Analyse the steps that could link a qualitative or quantitative research article, to evidence based clinical practice. Include the role of systematic reviews, meta-synthesis and clinical practice guidelines in your analysis. Incorporate the research article that was selected for your tutorial presentation, to support your discussion.

Implementation of evidence-based treatment protocols to manage fever, hyperglycemia, and swallowing dysfunction in acute stroke (QASC): a cluster randomized controlled trial

The article published in 2011 assessed the outcome of acute stroke patients undergoing that evidence-based multidisciplinary intervention for management of fever, hyperglycaemia and swallowing dysfunction 90 days after hospital admission written by (Middleton et al, 2011). Quantitative research was used in this article for the assessment of different control groups. Quantitative research is defined as collecting and using objectives and structuring data with science of numbers to avoid bias affecting the results (Liamputtong, 2010). The quantitative research has mainly been used in health sciences because it provides an understandable and describable format of human behavior and health issues.

Evidence-based practice (EBP) was also used in this article to analyse research and ultimately to validate evidence that answers clinical questions (Liamputtong, 2010). Five steps are included in EBP, the first step is formulating a well-built question. The second step to find articles or other related evidence-based resources that answer the question. The third step is appraised the evidence critically and assess its validity and usefulness. The fourth step is applying evidence which should be of sound quality and the last step is re-evaluating the evidence to see whether the action taken had obtained expected results. The essay will address how the quantitative research was used in combination with evidence-based practice, systematic reviews, meta-synthesis and clinical practice guidelines.

Firstly, PICO is the first step of systematic review which stands for population, intervention, comparison and the outcome of interest. It is a summarised document often written by a panel offering an integrated review of all related studies on a specific clinical or health-related topic. “The systematic review is using for both published and unpublished studies (focusing on clinical trials of similar treatments) and then summarizing the findings” (Ralf, 2006, p.2). Forming a question with PICO structure is a systematic way to identify the components of a clinical issue and clarify these components. This will guide the search for the evidence.

Secondly, in order to answer the question, research for evidenced based practices is the next step. In this article, researchers searched Medline and CINAHL database for reports in English which contain medical and life sciences literature, and the nursing and allied health literature, but there were no systematic reviews for the questions found. Although combining key terms, no studies had examined the combined effect of systematic management of fever, hyperglycaemia, or swallowing. Authors concluded that “implementation research is needed to identify effective strategies and to ensure resources are not wasted on activities of questionable value” (Middleton et al., 2011, p.1705). Existing evidence was scant for the clinical questions the authors wanted to address. .

Randomized controlled trial was used in this article because the method stratifies patient groups randomly and enables the variance of the groups to be matched. It reduces the confounding factors and bias, and enhances the standard and power of credibility (Mazor&Sabin, 2007). Before conducting randomized controlled trial, ethical consent should always be obtained from competent patients and the local guardians or representatives because any participation in research is governed by four ethical principles:...
