Evidence based medicine and patient centered medicine: some thoughts on thier integration.

Evidence-based medicine (EBM) and patient-centered medicine (PCM) are two movements that have emerged with great force in health systems in recent years. EBM has a population approach, and its primary objective is the generalization and improvement of health outcomes in the average patient. PCM has a personalized approach, focuses on individualization and improving health outcomes in specific patients. While EBM has its conceptual anchor in research, PCM has it in medical care. Despite EBM and PCM being perceived as conflicting movements, the profound changes that are currently taking place in health systems can facilitate the confluence of clinical research and medical care. This article constitutes a reflection on how research methods should approach the individual patient and medical practice should approach future patients. EBM and PCM, like research and medical practice, are two sides of the same coin, which should complement and aid each other. It is difficult to see how one of them can reach its full potential without the other as a continual reference, because PCM should not be practiced without being based on the best available evidence and it is impossible to imagine an EBM whose ultimate goal is disconnected from the individual patient.
