Test subjects and testing procedure
Thirty-five surgery residents (postgraduate year [PGY]-1 to PGY-5) rotating on 4-week general surgery or trauma services at Parkland Memorial Hospital were enrolled in the study between May and June 2001. All residents gave informed consent under a protocol approved by the University of Texas Southwestern Medical Center Institutional Review Board. The number of study subjects represented all residents rotating on each of the two services during the 2-month study period. Participants were tested
Results
The average age of the participants was 28 years (range 24 to 33). Twenty-six of 35 subjects were male. All 5 postgraduate years were represented with the following distribution: 13 PGY-1, 9 PGY-2, 8 PGY-3, 2 PGY-4, and 3 PGY-5 residents. Twenty-four of the residents held categorical positions in general surgery and the remaining were preliminaries destined to enter other surgical subspecialties.
As demonstrated in Table 2, results of pre-call and on-call performance were similar with respect to
Comments
This study specifically examined a set of skills required to perform laparoscopic surgery. It is not clear if our results could apply to other skills such as those required to perform open surgery. It is also important to note that other factors necessary for the safe performance of surgery were not examined such as cognitive skills and surgical judgment. In our study, one component of performance (errors) was adversely affected by sleep deprivation. Our findings indicate that sleep deprivation

2021, Journal of Surgical EducationCitation Excerpt :As increasing attention is paid to how surgeons perform whilst tired or stressed,19,20 being able to objectively assess how these conditions affect a surgeon's ability to operate could be beneficial, both to help identify warning signs, but also develop coping strategies to deal with such situations in clinical practice.21 There is some evidence in the literature demonstrating that simulated performance deteriorates when surgical trainees are fatigued or stressed,22,23 however as yet there is limited evidence on how best to identify and quantify deteriorating performance and more work is required in this area. Similarly, as evidence mounts for “warming up” prior to operating, simulators can provide surgeons with the opportunity to warm up without the logistical difficulties of restructuring operating list order or composition.24-26
