A hierarchy of evidence, comprising levels of evidence (LOEs), that is, evidence levels (ELs), is a heuristic used to rank the relative strength of results obtained from experimental research, especially medical research. There is broad agreement on the relative strength of large-scale, epidemiological studies.
The evidence used to change practice or make a clinical decision can be separated into seven levels of evidence that differ in type of study and level of quality. To properly implement EBN, the knowledge of the nurse, the patient's preferences, and multiple studies of evidence must all be collaborated and utilized in order to produce an ...

The concept of evidence-based assessment originated in the field of medicine, [3] and has since been adopted in several other disciplines, notably clinical psychology. The EBA approach is widely recognized as an empirically driven method of clinical decision-making. Cochrane reviews have reported the efficacy of EBA methods. [4]
