NCT01623674

Brief Summary

The aim of the study was to asses the effect of sleep deprivation during nightshift by monitoring 30 surgeons in unit of surgical gastroenterology in 4 consecutive days. The first day was pre call= day 1, second day was on call= day 2, third day was the first post call day = day 3 and fourth day was the second post call= day 4. The surgeons were monitored in order to asses how performance was on call compared to pre call and post call. The hypothesis was that they would perform worse on call than pre call, and again slightly worse post call.
