Transfusion medicine reviews
-
Informed consent for transfusions presumes that the patient has been "informed," meaning they have been given sufficient information to make an intelligent choice, and that they "consent," meaning that the patient is competent and free to consent. Although this may be oral or written, the latter is preferable for documentation and legal proof. This may either be as a chart note, or form. ⋯ If this process is performed by the physician talking to his/her patient, then, the patient is likely to be informed about, and consent to, elective transfusions. Once obtained and documented, that consent should be presumed to be valid with a course of therapy for transfusions. If some event significantly changes some aspects of the information on which the patient relied in consenting and now should be aware of, then, the patient should again give consent for transfusion, after being informed of this new information.
