With permission to nap, doctors stay more alert

While on call, doctors-in-training often spend 30 hours at a stretch at a hospital. Although they may catch catnaps when they’re not needed at a bedside, these interns develop fatigue that can pose risks to them and to their patients.

A new study tested the effects of giving such doctors greater permission to nap—by permitting them to hand off to another doctor the pager that summons them to the next patient.
