third year residents. The Accreditation Council for Graduate Medical Education (ACGME) has limited the number of work-hours to 80 hours weekly, overnight call frequency to no more than one in three, 30-hour maximum straight shifts, and at least 10 hours off between shifts. While these limits are voluntary, adherence has been mandated for accreditation. The Institute of Medicine (IOM) built upon the recommendations of the ACGME in the December 2008 report Resident Duty Hours: Enhancing Sleep, Supervision and Safety. While keeping the ACGME's recommendations of an 80-hour work week averaged over 4 weeks, the IOM report recommends that duty hours should not exceed 16 hours per shift for interns (PGY 1). The IOM also recommended strategic napping between the hours of 10pm and 8am for shifts lasting up to 30 hours. The ACGME officially recommended strategic napping between the hours of 10pm and 8am on 30-hour shifts for residents who are post graduate year 2 and above but did not make this a requirement for program compliance. The report also suggests residents be given variable off-duty periods between shifts, based on the timing and duration of the shift, to allow residents to catch up on sleep each day and make up for chronic sleep deprivation on days off. Though the ACGME regulations were intended to increase medical resident sleep hours and improve patient safety, they had also created unintended negative consequences in the education of new residents and the workplace learning culture. In 2017, the ACGME changed its regulations once again, citing a trial conducted from July 2014 to June 2015 in 117 general surgery residency programs. In the Flexibility in Duty Hour Requirements for Surgical Trainees (FIRST) trial, programs were randomly assigned to a group following current ACGME duty-hour restrictions or a group with more flexible policies that waived rules on maximum shift lengths and time off between shifts. When looking at primary outcomes of 30-day rate of postoperative death or serious complications, less-restrictive duty-hour policies were not associated with an increased rate of death or serious complications. Starting July 1, 2017, the ACGME raised the maximum number of consecutive hours a first year resident can work from 16 hours to 24 hours. Despite the sleep deprivation medical residents constantly experience due to long working hours, a minority of residents still wish to not have work hour regulations at all. In the survey of 4510 obstetric-gynecologic residents, about one
