The tradition of long hours on the floor is an old one in American medical training. And criticism of this tradition is of long standing too. The controversy over the grueling residency schedules is not a new one, but neither is it one that has been successfully resolved. It can still spark off strong feelings in both the proponents and opponents of cutting back on the length of residency shifts and/or the time off between shifts for professionals engaged in this important stage in their medical education. What’s more, it is a topic which has pitted respected healthcare institutions such as the Harvard School for Public Health and the American Academy of Family Physicians against one another, so much so that this issue is not likely to be resolved anytime soon.
