Over the last decade, advances in artificial intelligence (AI) technologies have created transformational opportunities for health, health care, and biomedical science. While new tools are available to improve effectiveness and efficiency in myriad applications in health and health care, challenges persist, including those related to increasing costs of care, staff burnout and shortages, and the growing disease burden of an aging population. The need for new approaches to address these long-standing challenges is evident and AI offers both new hope and new concerns. An Artificial Intelligence Code of Conduct for Health and Medicine: Essential Guidance for Aligned Action presents a unifying AI Code of Conduct (AICC) framework developed to align the field around responsible development and application of AI and to catalyze collective action to ensure that the transformative potential of AI in health and medicine is realized. Designed to be applied at every level of decision making--from boardroom to bedside and from innovation labs to reimbursement policies--the publication serves as a blueprint for building trust, protecting patients, and ensuring that innovation benefits people.
