The degradation in robotic skills that occurs during periods of robotic surgical inactivity in newly trained surgeons was measured. The role of animate training in robotic skill was also assessed.
Robotically naive resident and attending surgeons underwent training with the da Vinci robot on needle passage (DN), rocking ring transfer peg board (RPB), and running suture pod tasks (SP). Errors were established to convert actual time to adjusted time. Participants were deemed "proficient" once their adjusted times were within 80% of those set by experienced surgeons through repeated trials. Participants did not use the robot except for repeating the tasks once at 4, 8, and 12 weeks (tests). Participants then underwent animate training and completed a final test within 7 days.
Twenty-five attending and 29 resident surgeons enrolled; 3 withdrew. There were significant increases in time to complete each of the tasks, and in errors, by 4 weeks (Adjusted times: DN: 122.9 +/- 2.2 to 204.2 +/- 11.7, t = 6.9, P < .001; RPB: 262.4 +/- 2.5 to 364.7 +/- 8.0, t = 12.4, P < .001; SP: 91.4 +/- 1.4 to 169.9 +/- 6.8, t = 11.3, P < .001). Times decreased following animate training, but not to levels observed after proficiency training for the RPB and SP modules.
Robotic surgical skills degrade significantly within 4 weeks of inactivity in newly trained surgeons. Animate training may provide different skills than those acquired in the dry lab.
对新培训外科医生在机器人手术不活动期间出现的机器人技能退化情况进行了测量。还评估了活体训练在机器人技能方面的作用。
初次接触机器人的住院医师和主治医生使用达芬奇机器人进行了针穿刺(DN)、摇环转移钉板(RPB)和连续缝合吊舱任务(SP)的训练。通过将实际时间转换为调整时间来确定误差。参与者一旦其调整时间在经验丰富的外科医生通过反复试验设定的时间的80%以内,即被视为“熟练”。参与者除了在第4、8和12周重复一次任务(测试)外,不使用机器人。然后参与者接受活体训练,并在7天内完成最终测试。
25名主治医生和29名住院医师登记参加;3人退出。到第4周时,完成每项任务的时间和误差均显著增加(调整时间:DN:122.9±2.2至204.2±11.7,t = 6.9,P <.001;RPB:262.4±2.5至364.7±8.0,t = 12.4,P <.001;SP:91.4±1.4至169.9±6.8,t = 11.3,P <.001)。活体训练后时间有所减少,但对于RPB和SP模块,未降至熟练训练后观察到的水平。
新培训外科医生在不活动4周内,机器人手术技能显著退化。活体训练可能提供与在模拟实验室中获得的技能不同的技能。
