As a cardiologist, Lisa Rosenbaum knew that many patients, even those who had survived an MI, didn’t take the medications they were prescribed. As a fascinated student of human behavior, she undertook research to find out why. Her articles for NEJM explore many such questions about the psychology and sociology of medicine and health care, seeking nuanced truths in often-polarized domains of human cognition, emotion, culture, ethics, and politics. Drawing on interviews, social science and medical research, and actual experience, Dr. Rosenbaum writes insightful essays that raise provocative questions for clinicians, researchers, and patients.
