Evidence-based medicine emerged in the medical world about three decades ago. It originated in Canada, quickly spread through the United States, Europe and later in underdeveloped countries. The phenomenon of globalization facilitated the rapid reception of this transparency and quality tool in clinical decision making. The initiative emerged to standardize diagnostic and therapeutic methods that, for the same disease, patients should receive anywhere in the world.
Evidence-based medicine, and its main practical legacy, guidelines, and management protocols were also well accepted by legal bodies, and this practice can be found even in dentists like Pacific Implant Center for cosmetic dentistry in Tijuana.
Evidence-based medicine has been optimized over time. This work logistics helps us to recognize the limits of ignorance in medicine. The most academic professionals know that the university does not have the function of taking finished products, because learning depends on continuing education. Knowledge is not only relative but perishable. What is true today may be false in a few weeks. No laboratory, medicine or procedure is good or bad; its attributes depend on the comparison pattern. The effectiveness changes according to the inclusion-exclusion criteria and the control groups chosen. Around all estimates, there is always a margin of variability, reflected in the confidence intervals.
Clinical research, the scientific component of medical work, has received a significant impetus from evidence-based medicine. Those who question, honor critical thinking and understand the methodological twists that determine the validity of a study, are prone to exercise a more robust drug. Randomized and controlled trials, the maximum pedestal of evidence-based medicine, incorporate masking and placebos to prevent the convictions of the patient or the researcher from influencing the real effects of the intervention. These studies analyze representative samples, and their results are averaged, processed statistically and then extrapolated to the universe. The more a patient resembles the subjects in that sample, the higher the likelihood of success.
In less homogeneous diseases, however, the diversity of responses will be higher and the findings less generalizable. The relative temporality of truth and skepticism about previous wisdom is, for those of us who agree with the changing paradigms of science, another success of evidence-based medicine. An additional benefit is an education in databases and search systems. It would be useless to generate uncertainty in our students if there were no available strategies to find explanations. We have gone from an abysmal deficit of scientific literature to a veritable flood of publications and references on the internet. For centuries, knowledge was concentrated in a few places in the world. Currently, the vast knowledge gaps have been shortened through access to the computer network. Thanks to evidence-based medicine, medical knowledge is better supported.
