Robotic Cardiac Surgery Wet Lab Simulation Study

Aalborg University Hospital19 enrolled

Overview

The goal of this study is to investigate validity of the wet lab robotic cardiac surgery model used for training in robotic cardiac surgery and to evaluate learning curves in trainees of different surgical specialities. The investigators hope to recruit experienced robotic cardiac surgeons (experts) and cardiac and non-cardiac surgeons with minimal robotic experience (trainees). Participants will perform three predetermined tasks common in the wet lab robotic cardiac surgery training. Participants will be evaluated at baseline for each task. From experts' performance the mastery learning level will be calculated. Trainees will perform the tasks until mastery is achieved. The investigators will then be able to evaluate validity of the wet lab model and analyze learning curves in all participants by rating their performance.

Inclusion Criteria: * Experienced robotic cardiac surgeons: robotic surgeons with total volume \> 50 robotic cardiac operations and at least 20 robotic cases annually * Cardiac surgeons with limited robotic experience (robotic novices): on-going or completed cardio-thoracic residency * Non-cardiac surgeons with limited robotic experience (robotic novices): on-going or completed surgical specialty residency (general surgery, urology, gynaecology, ENT surgery) Exclusion Criteria: * Robotic novices with \> 5 hours experience of any robotic system

Outcomes

Primary Outcomes

Time-based Score

The time-based score (TBS) was calculated as follows: TBS = maximal total training time per task - actual completion time - errors. Units of measure - seconds. Minimum score 0, Maximum score 1222. TBS was calculated in seconds, where 0 was the lowest score and a higher number indicated a faster time to perform the task. The score range

Time frame: 6 months

Secondary Outcomes

Modified Global Evaluative Assessment of Robotic Skills (mGEARS)

In modified Global Evaluative Assessment of Robotic Skills (mGEARS) the tasks were not rated on autonomy domain as autonomy could not be evaluated from recordings. The mGEARS score was used to evaluate the overall robotic proficiency by 5 domains: depth perception, bimanual dexterity, efficiency, force sensitivity, and robotic control. The score ranged from 5 to 25, where 5 and 25 indicated the least and most proficient performance, respectively.
