In addition to turning up primary findings (the medical information that is being sought through metabolic and genetic testing, imaging studies, and other forms of examination), physicians and researchers may also generate incidental or secondary findings about their patients and research subjects that are of significance for their health or reproductive choices. There is one increasingly important area where incidental findings are difficult to predict: research using material from “repositories” of clinical samples and data where the outcomes of experimental procedures may not be anticipated and the purpose of the research cannot be known at the time a person gives permission for his or her material to be included in the repository. This session will address the question: How do USC clinicians and researchers handle incidental and secondary findings now and how will they handle them as research repositories are established at the Keck Hospital and LAC+USC Medical Center?
