The evolution of medicine. In the past, medicine was practiced according to the signs and symptoms presented by the patient and was solely based on the individual knowledge of the physician and thus was called intuition medicine. Currently, medicine is based on the evidence produced by scientific research, including clinical trials, which is designated as evidence-based medicine. In the future, medicine will be practiced according to algorithms that will take into consideration the patient's characteristics, such as their genome, epigenetics, and lifestyle, constituting precision medicine.
