Advance directives (ADs) allow patients to express their medical treatment preferences. Patients with ADs are more likely to receive medical care concordant with their wishes and are less likely to die in the hospital than patients without them, but use remains low in the US. Maria Silvera, MD, a palliative care physician and associate professor of medicine at the University of Michigan, and Catherine Auriemma, MD, a fellow in pulmonary/critical care medicine at the University of Pennsylvania, discuss the importance of ADs and strategies to increase their uptake.

The podcast on structural racism based on the discussion between Dr Ed Livingston and Dr Mitch Katz has been withdrawn. Comments made in the podcast were inaccurate, offensive, hurtful, and inconsistent with the standards of JAMA. Racism and structural racism exist in the US and in health care. After careful consideration, I determined that the harms caused by the podcast outweighed any reason for the podcast to remain available on the JAMA Network. I once again apologize for the harms caused by this podcast and the tweet about the podcast. We are instituting changes that will address and prevent such failures from happening again.

Next Generation Sequencing of Infectious Pathogens in Public Health and Clinical Practice
Next-generation sequencing is a catchall term for new, high-throughput technologies that allow rapid sequencing of a full genome. It can be used to sequence a patient’s DNA in diagnosing a genetic disorder or characterizing a cancer, but it can also be used to sequence the genome of a pathogenic bacteria, virus, fungi, or parasites. In this JAMA clinical review podcast, we talk with authors Marta Gwinn, MD, MPH, and Gregory L. Armstrong, MD, from the CDC, about how next-generation sequencing of infectious pathogens is being implemented in clinical practice and in public health surveillance for infectious disease.
