To study the effects of fatigue on general surgery residents' performance on the da Vinci Skills Simulator (dVSS).
15 General Surgery residents from various postgraduate training years (PGY2, PGY3, PGY4, and PGY5) performed 5 simulation tasks on the dVSS as recommended by the Robotic Training Network (RTN). The General Surgery residents had no prior experience with the dVSS. Participants were assigned to either the Pre-call group or Post-call group based on call schedule. As a measure of subjective fatigue, residents were given the Epworth Sleepiness Scale (ESS) prior to their dVSS testing. The dVSS MScore™ software recorded various metrics (Objective Structured Assessment of Technical Skills, OSATS) that were used to evaluate the performance of each resident to compare the robotic simulation proficiency between the Pre-call and Post-call groups.
Six general surgery residents were stratified into the Pre-call group and nine into the Post-call group. These residents were also stratified into Fatigued (10) or Nonfatigued (5) groups, as determined by their reported ESS scores. A statistically significant difference was found between the Pre-call and Post-call reported sleep hours (p = 0.036). There was no statistically significant difference between the Pre-call and Post-call groups or between the Fatigued and Nonfatigued groups in time to complete exercise, number of attempts, and high MScore™ score.
Despite variation in fatigue levels, there was no effect on the acquisition of robotic simulator skills.
研究疲劳对普通外科住院医师在达芬奇技能模拟器（dVSS）上表现的影响。
15 名来自不同研究生培训年限（PGY2、PGY3、PGY4 和 PGY5）的普通外科住院医师按照机器人培训网络（RTN）的建议在 dVSS 上完成 5 项模拟任务。这些普通外科住院医师以前没有使用过 dVSS。参与者根据值班安排分为预呼叫组或后呼叫组。作为主观疲劳的衡量标准，住院医师在进行 dVSS 测试前接受了 Epworth 嗜睡量表（ESS）。dVSS MScore™软件记录了各种指标（客观结构化评估技术技能，OSATS），用于评估每位住院医师的表现，以比较预呼叫和后呼叫组之间的机器人模拟熟练程度。
6 名普通外科住院医师分为预呼叫组，9 名分为后呼叫组。这些住院医师还根据他们报告的 ESS 评分分为疲劳（10 名）或非疲劳（5 名）组。预呼叫和后呼叫报告的睡眠时间（p=0.036）之间存在统计学显著差异。在完成练习的时间、尝试次数和高 MScore™得分方面，预呼叫和后呼叫组之间或疲劳和非疲劳组之间没有统计学显著差异。
尽管疲劳程度存在差异，但对机器人模拟器技能的掌握没有影响。
