Reacción a "Substituting physicians for nurses in hospital interventions does not affect patient safety, says review"

The topic is profound and the conclusions are striking, as it concludes that there is no difference in such important areas as mortality or patient safety. It is necessary to take a closer look at the entire study. As a preliminary comment, the study is of great interest, given that the demand for healthcare professionals is growing, and we often do not optimise the tasks we assign to our professionals—bearing in mind that the study has focused on countries with healthcare models different from ours. In Spain in particular, healthcare professionals and, often, family doctors have to spend a large part of their time on administrative processes that could be reorganised with administrative staff and by taking advantage of new technologies. On the other hand, there are healthcare tasks that can be delegated to other healthcare professionals, not only nurses, but also physiotherapists, psychologists, pharmacists, etc. Some of these are indicated in the study, but others do not appear here, such as minor symptoms, screening, or specific follow-ups. In any case, it is important to clearly establish the roles of delegation and coordination for this to be effective, who assumes responsibility, whether there is supervision, etc., while being aware that there are roles that cannot be transferred from the doctor, such as diagnosis or surgery.
