Shared Decision-Making is a widely accepted model of the physician–patient relationship providing an ethical environment in which physician beneficence and patient autonomy are respected. It acknowledges the moral responsibility of physician and patient by promoting a deliberative collaboration in which their individual expertise—complementary in nature, equal in importance—is emphasized, and personal values and preferences respected. Its goal coincides with Pellegrino and Thomasma’s proximate end of medicine, that is, a technically correct and morally good healing decision for and with a particular (...) patient. We argue that by perfecting the intellectual ability to apprehend the complexity of clinical situations, and through a perfection of the application of the first principles of practical reason, prudence is able to point toward the right and good shared medical decision. A prudent shared medical decision is therefore always in keeping with the kind of person the physician and the patient have chosen to be. (shrink)
