Electronic Health Records (EHRs) are used across a wide variety of activities in cancer care and cancer research, including communication among health care team members and patients, clinical documentation and treatment planning, patient safety and quality improvement, scheduling and billing, as well as clinical research and disease surveillance activities. On February 28 and March 1, 2022, the National Cancer Policy Forum and the Computer Science and Telecommunications Board of the National Academies of Sciences, Engineering, and Medicine hosted a public workshop to examine opportunities to improve patient care and outcomes through collaborations to enhance innovation in the development, implementation, and use of EHRs in oncology care, research, and surveillance. This Proceedings of a Workshop summarizes the presentations and discussions that took place at the workshop.
