Consider the purpose and process of meta-analysis or metasynthesis and how it informs evidence-based practice. How do recommendations made on the basis of these meta-analyses work to improve quality of care? Why would basing a practice change on one research article be unreliable?

Answer
Evidence-Based Practice
Meta-syntheses and/or meta-analyses informs evidence-based practices since recommendations can inform policy change or practice change with focus on improvement of care quality and safety. Meta-synthesis integrates findings from numerous qualitative studies, whereas meta-analysis integrates findings from numerous quantitative studies (Manimozhi & Srinivasan, 2018). Meta-syntheses and/or meta-analyses inform policy change and/or practice change for improvement of care safety and quality since they generate a combined larger, general, and/or whole statement that can be relied upon (Manimozhi & Srinivasan, 2018). Meta-analyses or meta-syntheses can explore wide and in-depth evidence beyond what is known on a given time to inform evidence-base practice. For instance, meta-analyses or meta-syntheses can help nurses develop new insights on what are and how to implement safe and high-quality nurse prescription practices (Darvishpour, Joolaee, & Cheraghi, 2014). The strength of reliability lies on the fact that what is included in evidence-based practices, be it a given treatment, practice, or medication, has already been established has having significant level in effect size, which is consistent across numerous studies (Darvishpour, Joolaee, & Cheraghi, 2014). As such, meta-analyses or meta-syntheses provide reliable evidence and recommendations for transforming evidence-based practice.
It is unreliable to base practice change on a single research article. It is unreliable to do so since it is difficult to evaluate the direction and amount of bias in the primary source of evidence. In other words, it would be difficult to determine whether investigator(s) has represented a given phenomenon or issue in an objective manner or not. The author(s) of one article might have been influenced by tacit unconscious views when analyzing/synthesizing results as well as when developing conclusions and recommendations. The author(s)’s assumptions, tone, basis of conclusions, and interests might have influenced the content, evidence, and conclusions in the single journal article, making it unreliable for acting as a basis for practice change (Manimozhi & Srinivasan, 2018). Besides, content and findings in one article might contradict that presented in another article; hence, resulting in confusion as to which article present accurate and reliable evidence (Darvishpour, Joolaee, & Cheraghi, 2014). As such, a single article cannot provide reliable evidence and recommendations for transforming evidence-based practice.
