Informed consent: an overview.

Informed consent is a process, not an isolated incident. It therefore requires that health care professionals approach the process with expert knowledge, open communication, and a willingness to participate in shared decision-making. Table 2 identifies the major ethical and legal issues of informed consent. Legal precedents and professional collaboration will be necessary to further define and refine informed consent. The complexity of treatment regimens, potential system toxicities, and the chronicity of the disease process have fostered the development of a multidisciplinary team approach to the care of oncology patients. Therefore, collaboration is essential to meet the demands of the informed consent process and provide an optimal environment for the oncology nurse to intervene actively as a patient advocate.
