Hemoderivative and blood transfusions without proper medical indication bring uncertain benefits, increase health risks and adverse effects. It is necessary to also consider the patient's values and preferences and the denial to receive transfusions. A deficient medical evaluation and an unnecessary transfusion can generate untoward effects regarding patients' health and safety. ⋯ Several studies coincide on the high number of unnecessary or unjustified blood transfusions. To improve the quality of transfusion medicine steps should be taken to install specialized hospital committees, update the use of guidelines based on the best scientific evidence, as well as to respect patient autonomy.
