J Neurosurg Sci. 2022 Feb;66(1):49-53. doi: 10.23736/S0390-5616.21.05331-5. Epub 2021 Aug 3.


Since its inception, medical training and practice are based primarily on the clinical experience provided by the mentors of each of the medical schools. In the 1990s, the first steps were taken for the construction of what we now know as evidence-based medicine. Evidence-based medicine is the set of studies, methods, and principles for the prevention of medical diseases, management guidelines, and algorithms used in sources of evidence. Neurosurgery based on evidence has emerged thanks to advances in neuroscience and information technology that allows the globalization of current scientific information. The results of important reviews on the levels of evidence in neurosurgery are low in percentages of high-quality evidence in this field of medicine. Based on the above, the aim of this manuscript was to describe the application of evidence in neurosurgery, the current state of the art in evidence-based medicine, and the steps needed to create evidence of the best quality in neurosurgery.
