Grand rounds are an important teaching tool and ritual of medical education and inpatient care, consisting of presenting the medical problems and treatment of a particular patient to an audience consisting of doctors, residents and medical students. The patient was traditionally present for the round and would answer questions; grand rounds have evolved with most sessions now rarely having a patient present and being more like lectures. An actor portrays the patient in some instances. Grand rounds help doctors and other healthcare professionals keep up to date in important evolving areas which may be outside of their core practice. Most departments at major teaching hospitals will have their own specialized, often weekly, grand rounds. Attending grand rounds is also an important supplement to medical school and on-the-job resident training. (Grand rounds can also be distinguished from rounds which is the (typically) daily visit by the attending physician and team to all that physicians patients on the ward. Rounding with an attending physician is an important part of medical on-the-job training and education, but its primary focus is immediate care for the patients on the ward. Grand rounds tends to present the bigger picture, including experience with patients over many years, and the newest research and treatments in an area. Grand rounds tend to be open to the entire medical professional community, whereas rounds are specific to individual attending physicians and their teams). Many teaching and research hospitals have started providing streaming video of their grand rounds presentations for free over the Internet. This is an opportunity for medical professionals and students to improve their knowledge, and builds on one of the core values of the Hippocratic Oath – that medical education should be provided for free, and that doctors should actively and openly share their knowledge without compensation in order to improve patient care.
