As part of the overall disability determination process, the Social Security Administration uses a step-by-step approach to understand how severe an individual's condition is and whether it meets program criteria for disability. The use of various types of biomarkers has been suggested as a way to strengthen the amount and quality of objective evidence available to the review process. At the request of the Social Security Administration, the National Academies of Sciences, Engineering, and Medicine's Board on Health Care Services organized a virtual workshop on July 21, 2020, titled The State of the Science of the Use of Biomarkers to Establish the Presence and Severity of Impairments. Workshop discussions focused on the current and potential uses for biomarkers; explored legal and ethical implications associated with biomarker use in clinical decision making; and considered the possible uses of nongenetic biomarkers as tools for the diagnosis or prognosis of the severity of specific physical and mental impairments. This publication summarizes the presentations and discussion of the workshop.

Delivering high-quality cancer care to all patients presents numerous challenges, including difficulties with care coordination and access. Patient navigation is a community-based service delivery intervention designed to promote access to timely diagnosis and treatment of cancer and other chronic diseases by eliminating barriers to care, and has often been proposed and implemented to address these challenges. However, unresolved questions include where patient navigation programs should be deployed, and which patients should be prioritized to receive navigation services when resources are limited. To address these issues and facilitate discussion on how to improve navigation services for patients with cancer, the National Cancer Policy Forum of the National Academies of Sciences, Engineering, and Medicine held a workshop on November 13 and 14, 2017. At this workshop, a broad range of experts and stakeholders, including clinicians, navigators, researchers, and patients, explored which patients need navigation and who should serve as navigators, and the benefits of navigation and current gaps in the evidence base.
