It’s important to remember that there are many reasons (age, class, race or ethnicity, unfamiliarity with medical practices, different attitudes towards medicine) why patients might feel able or unable to advocate for themselves in a medical setting. Nineteenth century medical practices did not operate within the same informed consent framework we use today. Informed consent is an ethical and legal concept that gives patients the right to understand what medical treatments they will receive and agree to, or refuse, those treatments. For more information about the history of informed consent, please see the Encyclopedia of Bioethics entry "History of Informed Consent."
