Ethics and conflicts of interest are important considerations when planning and carrying out research. It is the role of the institutional review board to weigh these against protection of the research subject when evaluating research proposals. The ethical considerations when performing research include basic ethical principles (e.g., autonomy, confidentiality, non-maleficence, informed consent, beneficence, justice, and utility), as well as nuances such as appropriate study designs, investigator conflict of interests, and bias in all its forms. To help guide clinicians, a number of professional and governmental organizations have published guidelines and recommendations on various aspects of clinical research (e.g., the American Medical Association, the National Institutes of Health, and the US Food and Drug Administration).
