<p>The United States faces a significantly aging population as well as a growing share of the population that is living longer with multiple chronic conditions. To provide high-quality care to people of all ages living with serious illness, it is critical that the nation develop an adequately trained and prepared workforce consisting of a range of professionals, including physicians, nurses, social workers, direct care workers, and chaplains. To explore some of the key workforce-related challenges to meeting the needs of people with serious illness, the National Academies of Sciences, Engineering, and Medicine hosted a workshop on November 7, 2019. This publication summarizes the presentations and discussions from the workshop.</p>
