Biomedical informatics in Health (BIH) is the discipline in charge of capturing, handling and using information in health and biomedicine in order to improve the processes involved with assistance and management. Informatic nephrology has appeared as a product of the combination between conventional nephrology with BIH and its development has been considerable in the assistance as well as in the academic field. Regarding the former, there is increasing evidence that informatics technology can make nephrological assistance be better in quality (effective, accessible, safe and satisfying), improve patient's adherence, optimize patient's and practitioner's time, improve physical space and achieve health cost reduction. Among its main elements, we find electronic medical and personal health records, clinical decision support system, tele-nephrology, and recording and monitoring devices. Additionally, regarding the academic field, informatics and Internet contribute to education and research in the nephrological field. In conclusion, informatics nephrology represents a new field which will influence the future of nephrology.
