The work of the authors  towards robotic training and credentialing is much needed and should be applauded as increased scrutiny is being placed on complications associated with robotic surgery . The authors held three separate meetings in 2012 and 2013 in which they identified themes, developed a training curriculum, and assessed expert agreement with their proposed curriculum. The authors’ quantitative survey of 24 experts revealed that all ‘agreed’ or ‘agreed strongly’ with the proposed curriculum. The curriculum includes three areas, cognitive, psychomotor, and teamwork/communication skills, which we feel are vital for good outcomes . As was noted, there are available ‘E-learning’ tools online from organisations such as the AUA and from Intuitive Surgical, and these can be further expanded and validated [4, 5]. The AUA also has recommendations for credentialing requirements that are available online.
We agree with the authors  that simulation should include inanimate models, which provide a good cost to benefit ratio. There are increasing numbers of inanimate models for the simulation of procedures, e.g. partial nephrectomy and pyeloplasty. One limitation of inanimate training is that the entire robotic surgical system is used and it may only be free for training on nights and weekends when the robotic systems are not being used clinically. Virtual reality simulators offer a more convenient way to become familiar with the robotic environment, but at a cost of ≈$100 000 (American dollars). Virtual reality simulation is predominantly used to develop skills for a junior trainee or a novice surgeon. However, procedure-specific and augmented-reality simulation is being developed and will greatly enhance robotic training.
The authors  should be applauded for offering a specific curriculum consisting of online training, an 8-day ‘discovery’ course for simulation and observation, and a 6-month fellowship for step-wise progression to ‘live’ surgical console time. As the authors note, credentialing should be based on competency and not on the number of cases logged or the duration of training alone. The duration of the fellowship should be based on the learning objectives and research/academic requirements.
In the USA, robotic surgical training is included during residency in urology and a fellowship may not be required if a graduating resident is proficient according to the programme directors’ assessment. For surgeons who have not been trained during residency, proctoring by an experienced surgeon is recommended by the AUA , after completing a structured robotic surgical curriculum as described in this article . However, a validated curriculum and benchmarks for competency have not been established. The Fundamentals of Robotic Surgery (FRS) curriculum will be validated during the next year for a multidisciplinary curriculum with skills testing .
We also agree with the authors  that non-technical skills such as trouble-shooting, teamwork, leadership, and communication are critically important for preventing adverse events. Many if not most complications occur due to failures in patient selection, trocar positioning, and bedside assisting. Also, many complications can be traced to ‘system’ problems rather than console performance. Robotic surgery requires a proficient team to ensure good outcomes.
Currently, there are no uniform credentialing requirements to practice robotic surgery in the USA or many other countries. A validated robotic training curriculum with competency-based assessments is essential and can be integrated into residency programmes where robotic technology is readily available. Where robotic surgical volume is inadequate, fellowship programmes can provide the needed training. A validated competency-based approach offers the hope of better patient outcomes and the continued acceptance of new technologies such as robotic surgery.
