In normal hospitals, the Gynecology Department and the Emergency Department were renowned for working their doctors to death. This was especially true for the Gynecology Department because most childbirths occurred at night. Hence, the doctors of the Gynecology Department had to work frequent night shifts.
Besides, unlike departments like the Department of Hepatobiliary and Pancreatic Surgery where the doctors on night shift got to sleep through the night 90% of the time, the Gynecology Department was always flooded with patients at night. It was rare for doctors of the Gynecology Department to get a good night's sleep while they were on the night shift.
