Best research evidence is produced by the conduct and synthesis of numerous high-quality studies in a selected health-related area.

(Melnyk, 2004) The weakest level of evidence is the opinion from authorities and/or reports of expert committees. Some methodologies for qualitative evidence synthesis recommended by Cochrane are meta-ethnography, thematic synthesis and framework synthesis. Typically, the overarching aim of the project, your epistemology and the in-house expertise will assist in the decision making process of what methodologies to choose as will your worldview regarding realism and idealism within qualitative inquiry and qualitative science. Evidence syntheses are conducted in an unbiased, reproducible way to provide evidence for practice and policy-making, as well as to identify gaps in the research. Evidence syntheses may also include a meta-analysis, a more quantitative process of synthesizing and visualizing data retrieved from various studies.

You will see many different versions of the evidence hierarchy pyramid. However, they all have commonalities: - Meta-Analysis / Meta-Synthesis / Systematic Review: These are sources of high level evidence as they are analyses of existing research. They are generally at the top of the evidence pyramid. Be sure to look at inclusion/exclusion criteria and forest plots to appraise the quality of the source.

This table suggests study designs best suited to answer different types of clinical question. The systematic review or meta-analysis of randomized controlled trials (RCTs) and evidence-based practice guidelines are considered to be the strongest level of evidence on which to guide practice decisions.

Level III: Evidence from evidence summaries developed from systematic reviews; Level IV: Evidence from guidelines developed from systematic reviews; Level V: Evidence from meta-syntheses of a group of descriptive or qualitative studies The notion that a synthesis that includes mathematically combining a complete body of evidence provides the highest level of evidence is attractive. However, as with most of evidence-based medicine, the principles are rational, consistent, and appealing, but in practice are fraught with practical challenges, ambiguities, and nuances. You might not always find the highest level of evidence (i.e., RCT, systematic review/meta-analysis) to answer your question. When this happens, work your way down to the next highest level of evidence. This table suggests study designs best suited to answer different types of clinical question.
