The Importance of a Culture Change in Sleep

There is some literature and particularly among residents to show that residents on night shifts make more errors. I don't know that there is anything yet that shows that this particular ready score correlates with this number of patients, patient significant errors. And so I think this is several steps down the road. It may not be enough to say, Oh, look, doctors are tired. Doctors aren't sleeping well, but it may have a bit more a little bit more impact if we can say, Hey, this is harming patients.
