According to its critics and detractor, scientific medicine and the Evidence-Based Medicine (EBM) program have failed. EBM is a program that seeks to respond to the need to systematise medical knowledge, improve the decision-making process in health and thus improve health systems. Despite its wide dissemination, it is not without criticism, from the questioning of its positivist philosophical approach, to its strictly biological and of effectiveness vision, and to the undeniable conflict of interests of biomedical research, which is mostly financed by the pharmaceutical industry. However, despite its limitations, there is still a long way to go, and its scope and benefits are already demonstrated in the current making of medical decisions.
