Recognizing the role of technology in the development of medicine and the impact of telecommunication advances, we reflect on the meaning and ethics of the use of Telemedicine, both in its general dimension for the use and distribution of knowledge, as well as in the delivery of health actions, scientific research, and data management. Teleconsultation is discussed in greater detail, analyzing its process and application, reviewing its possible advantages and disadvantages, from the point of view of providers and patients. We highlight the need to carry out an appropriate evaluation of each instance, from the point of view of both the patient and the professional who uses it. The importance of maintaining a doctor-patient relationship in agreement with the nature and practice of Medicine, respecting people's dignity, is emphasized. We mention the ethical conditions that must be bore in mind for the proper use of telemedicine. We discuss the eventual influence that this practice will have on the concept and practice of medical care, while suggesting the need to legislate on the matter.
