[Why is it increasingly difficult to "do the right thing" and to "stop doing the wrong thing"? Strategies for reversing low-value practices].

This manuscript describes the factors that have led to the spread of low-value practices (LVP) and the main initiatives to reverse them. The paper highlights the strategies that have proven to be most useful over the years, from the alignment of clinical practice with "do not do" recommendations, to quaternary prevention and the risks associated with interventionism. Reversing LVP requires a planned process with a multifactorial approach engaging the different actors involved.

[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.

[Patient participation in its own safety].

Patient-centered approach to care and regulatory advances developed in recent years have promoted patient involvement in decision-making about diagnostic tests and treatments. In other aspects, such as participating in their own safety, there is still a lot to do. Until recently, the patient has been considered as a simple health services receiver, not as an active part of the system, much less as a safety barrier against failures and errors that occur in health care.
