 Residency training requires hospital presence twenty-four hours a day. At times this necessitates working extended shifts, including night shifts, resulting in altered sleep patterns and sleep deprivation. Since 2003, the Accreditation Council for Graduate Medical Education ACGME has enforced duty hour regulations limiting shift length, the amount of weekly hours worked, and other variables governing shift work. Numerous studies have sought to determine the impact of duty hour regulations on the quality of patient care and resident education.
