Randomized Controlled Trial Multicenter Study Comparative Study
Sleep and Alertness in a Duty-Hour Flexibility Trial in Internal Medicine.
A purpose of duty-hour regulations is to reduce sleep deprivation in medical trainees, but their effects on sleep, sleepiness, and alertness are largely unknown. ⋯ This noninferiority trial showed no more chronic sleep loss or sleepiness across trial days among interns in flexible programs than among those in standard programs. Noninferiority of the flexible group for alertness was not established.
