[Electronic medical record and prescription: risks and benefits detected since its implementation. Safe designing, rollout and use].

New information technologies have transformed the way care is delivered within health services, permeating almost every aspect of health care. As the complexity of the system increases, it becomes more difficult to work optimally without the assistance of new technologies. Although its implementation represents a breakthrough, either because of the advancement involved in the proper use of any technology in health care, or because of the development of specific applications that improve patient safety, other factors such as incorrect design, implementation and poor maintenance, inadequate training, along with overconfidence and dependency, can make technologies compromise patient safety. This article describes the beneficial effects, and those that are not so, of the introduction in our country of the electronic medical record and the electronic prescription on the healthcare quality and safety.
