Another study, published in 2010 in the Journal of Hospital Medicine, looked at efforts to encourage patient sleep — particularly by rescheduling activities, nighttime checks and overnight medication doses so as not to wake patients. That paper, co-written by Bartick, the Harvard professor, found a 49 percent drop in the number of patients who were given sedatives. That can have the added benefit of improving patient outcomes, since sedatives are associated with dangerous side effects such as falling or hospital delirium or confusion.
“Sleep disruptions are actually not benign as far as patients are concerned,” said Dana Edelson, an assistant professor of medicine at the University of Chicago and an author on the 2013 study. “We’re putting them at unnecessary risk when we’re waking them up in the middle of the night when they don’t need to be.”
And possibly making the recovery a bit more difficult.
“Patients will tell you, ‘I was so exhausted, I couldn’t wait to get home and go sleep,’” said Yale’s Pisani.
