Effect of XXXX on the performance of simulated laparoscopic surgical skill.

@entity1 @entity1949 @entity1295
BACKGROUND: Resident work hours may impact @entity1 care. We hypothesized that "call-associated" @entity1949 has no effect on technical dexterity as measured on a minimally invasive surgery trainer, virtual reality (MIST VR) surgical simulator. METHODS: Thirty-five surgical residents were prospectively evaluated pre-call (rested), on-call (rested), and post-call (acutely sleep deprived). @entity1 completed questionnaires regarding sleep hours and level of @entity1295 . Technical skill was assessed using the MIST VR. Speed, errors, and economy of motion were automatically recorded by the MIST VR computer simulator. Data were analyzed by paired Student t test and analysis of variance. RESULTS: Estimated hours of sleep and subjective indicators of @entity1295 were different between rested and sleep-deprived residents. The number of errors and time to complete all tasks increased at the post-call assessment. CONCLUSIONS: Resident work schedules lead to @entity1949 and @entity1295 . Call-associated @entity1949 and @entity1295 are associated with increased technical errors in the performance of simulated laparoscopic surgical skills.
