Objective:
To assess the efficacy of an intern surgical skills curriculum involving a boot camp for core open and laparoscopic skills, self-guided practice with positive and negative incentives, and semiannual performance evaluations.
Design:
Longitudinal cohort study.
Setting:
Academic tertiary care center.
Participants:
Intervention group (n = 15): residents who completed the intern surgical skills curriculum and had performance evaluations in fall of intern year, spring of intern year, and fall of second year. Control group (n = 8): second-year residents who were 1 year ahead of the intervention group in the same residency program, did not participate in the curriculum, and had performance evaluations in fall of second year.
Results:
In fall of second year of residency, the intervention group had better performance (presented as median values with interquartile ranges) than the control group on one-hand ties (left hand: 9.1 [6.3-10.1] vs 14.6 [13.5-15.4] seconds, p = 0.007; right hand: 8.7 [8.5-9.6] vs 11.5 [9.9-16.8] seconds, p = 0.039). The intervention group also had better performance on all open suturing skills, including mattress suturing (vertical: 33.4 [30.0-40.0] vs 55.8 [50.0-67.6] seconds, p = 0.001; horizontal: 28.7 [27.3-39.9] vs 52.7 [40.7-57.8] seconds, p = 0.003), and a water-filled glove clamp, divide, and ligate task (28.0 [25.0-31.0] vs 59.1 [53.0-93.0] seconds, p < 0.001). Finally, the intervention group had better performance on all laparoscopic skills, including peg transfer (66.0 [59.0-82.0] vs 95.2 [87.5-101.5] seconds, p = 0.018), circle cut (82.0 [69.0-124.0] seconds vs 191.8 [155.5-231.5] seconds, p = 0.002), and intracorporeal suturing (195.0 [117.0-200.0] seconds vs 359.5 [269.0-450.0] seconds, p = 0.002).
Conclusions:
Implementation of a comprehensive surgical skills curriculum was associated with improved performance on core open and laparoscopic skills. Further research is needed to understand and optimize motivational factors for deliberate practice and surgical skill acquisition.
