Also, do academic physicians have their residents/fellows do the call?(in say a big hospital)
Residents and fellows do not "do the call" for any attending physicians. Rather, they are often the first to handle questions, problems and new patients. These must then be discussed with the attending physician. Who stays all night at the hospital and who works from home is extremely variable based on the field and the hospital. I'll give you some examples that will help explain.
In general, a pediatric endocrinologist (this would be similar for many of the pedi specialties) will not have many middle-of-the night emergencies. There is no need for a pediatric endocrine specialist, either a fellow or attending to be in the hospital 24/7. In a large children's hospital, patients with endocrine problems will be watched at night by the residents who stay in the hospital. At a program with fellows, the fellow (who in this case will be at home) might be called at night/weekends by the resident for major problems or new consults. Regardless, there will always be an attending who is also on call from home. If a new admission comes in at night, or a new consult, the patient will likely be seen by the resident and/or fellow and the attending called. In unusual circumstances (a very sick diabetic for example), the attending might come in at night. On weekends, generally the attending will do morning rounds and then go home. So, in this example, the resident and fellow are taking call and seeing patients, but they are not taking call "for" the attending. The attending is still responsible even if they are not the one having to be there at night for problems. The attending will maintain some legal liability for what happens to their patients when they are on call as well in this setting.
In acute care fields, such as pediatric critical care, neonatal intensive care and pediatric cardiology, it is much more likely at large hospitals that the fellow will be in the hospital 24/7. At some programs, even the academic attendings will be in the hospital 24/7. Like me.
😎 In this case, the resident and fellows may still be the first to be called about problems, but the attending is close at hand to help them deal with the sickest patients and to see all new admissions.
There are lots more variations on this theme, but these examples can give you and others some idea. Being an academic attending does not mean that you don't take call or that someone else sees your patients for you. It means that you are the "last stop" on the line for calls in many cases, but that doesn't guarantee you a quiet night. The last two nights I was on-call I got a total of about 3 hours of sleep.
