To evaluate the preliminary validity and acceptability of a low-cost low-fidelity robotic surgery dry lab for training and assessing residents' technical proficiency with key robotic radical prostatectomy steps.
Three standardized inanimate tasks were created to simulate the radical prostatectomy steps of posterior dissection, neurovascular bundle release, and urethrovesical anastomosis. Urology trainees and faculty at a single institution completed and evaluated each dry lab task. Construct validity was evaluated by comparing task completion times and Global Evaluative Assessment of Robotic Skills scores across four participant cohorts: medical students (n = 5), junior residents (n = 5), senior residents (n = 5), and attending surgeons (n = 7). Content validity, face validity, and acceptability were evaluated through a posttask survey using a 5-point Likert scale.
There was a significant difference in the individual and composite task completion times and Global Evaluative Assessment of Robotic Skills scores across all participant cohorts (all < 0.01). The model was rated favorably in terms of its content validity and acceptability for use in residency training. However, model realism, compared with human tissue, was poorly rated. The dry lab production cost was less than US $25.
This low-cost procedure-specific dry lab demonstrated evidence of content validity, construct validity, and acceptability for simulating key robotic prostatectomy technical steps and can be used to augment robot-assisted laparoscopic prostatectomy surgical training.
评估一种低成本、低保真度的机器人手术干式实验室对于培训和评估住院医师关键机器人根治性前列腺切除术步骤技术熟练程度的初步有效性和可接受性。
创建了三项标准化的无生命任务，以模拟后入路解剖、神经血管束游离及尿道膀胱吻合等根治性前列腺切除术步骤。一所机构的泌尿外科实习生和教员完成并评估了每项干式实验室任务。通过比较四个参与者队列（医学生，n = 5；低年资住院医师，n = 5；高年资住院医师，n = 5；主治医生，n = 7）的任务完成时间和机器人技能整体评估得分来评估结构效度。通过使用5点李克特量表的任务后调查来评估内容效度、表面效度和可接受性。
所有参与者队列在个体和综合任务完成时间以及机器人技能整体评估得分方面均存在显著差异（均P < 0.01）。该模型在内容效度和用于住院医师培训的可接受性方面得到了较高评价。然而，与人体组织相比，模型的逼真度评价较差。干式实验室的生产成本低于25美元。
这种低成本的特定手术干式实验室在模拟关键机器人前列腺切除术技术步骤方面显示出内容效度、结构效度和可接受性的证据，可用于加强机器人辅助腹腔镜前列腺切除术的手术培训。
