The Institute of Medicine recently revised its work schedule recommendations for medical residents, in the wake of increasing concern about errors made related to medical resident fatigue. What are the new recommendations, and will these help enhance the learning environment for residents? Two of the Institute of Medicine's panel members who studied the residency process, Dr. Kenneth Ludmerer, professor of medicine and history at Washington University in St. Louis, and Dr. Daniel Munoz, fellow at Johns Hopkins University, discuss the goals of the new recommendations. Dr. Lee Freedman hosts.
