What levels of evidence are present in relation to research and practice and why are they important regardless of the method you use?
In relation to research and practice, evidence-based studies entails finding the most relevant evidence and applying it. As cornerstone of the EBP and research entails the hierarchical classification of the available evidence. Clinicians and researchers are thus encouraged to sea4rch for the highest level of evidence and use them to answer clinical questions. The assigning of levels to studies occur based on the methodological quality of the study design, its validity and applicability to patient care (Hande et al., 2017). As such, there are several levels of evidence. In level I, evidence from a systematic review or meta-analysis of all relevant RCTs (randomized controlled trial) or evidence-based clinical practice guidelines based on systematic reviews of RCTs or three or more RCTs of good quality that have similar results exists (“Levels of Evidence”, 2020). Level II entails evidence obtained from at least one well-designed RCT (e.g. large multi-site RCT). Level III comprises evidence obtained from well-designed controlled trials without randomization (i.e. quasi-experimental). Level IV encompasses evidence from well-designed case-control or cohort studies. Moreover, Level V comprises evidence from systematic reviews of descriptive and qualitative studies (meta-synthesis). Further, Levels VI and VII comprise evidence from a single descriptive or qualitative study and evidence from the opinion of authorities and/or reports of expert committees respectively.
The segregation of evidence in varied levels is important as it ensures that a researcher or clinician will at least find an article that supports their research question irrespective of the level. Whereas the hierarchy is based on the rigor of research methods, the hierarchies and levels of evidence are important since they reveal the quality of research that one will use in their studies (Hande et al., 2017). Moreover, varied types of research studies are answered by varied types of research designs, which informs the categorization of evidence. As such, the presence of levels makes it easier for one to find the requisite studies.
