Is Robotic Surgery Highlighting Critical Gaps in Resident Training?

Enhancing robotic efficiency through the eyes of robotic surgeons: sub-analysis of the expertise in perception during robotic surgery (ExPeRtS) study

BACKGROUND

Robotic technology affords surgeons many novel and useful features, but two stereotypes continue to prevail: robotic surgery is expensive and inefficient. To identify educational opportunities and improve operative efficiency, we analyzed expert commentary on videos of robotic surgery.

METHODS

Expert robotic surgeons, identified through high case volumes and contributions to the surgical literature, reviewed eight anonymous video clips portraying key portions of two robotic general surgery procedures. While watching, surgeons commented on what they saw on the screen. All interactions with participants were in person, recorded, transcribed, and subsequently analyzed. Using content analysis, researchers double-coded each transcript applying a consensus developed codebook.

RESULTS

Seventeen surgeons participated. The average participant was male (82.4%), 47 (SD = 6.6) years old, had 13.2 (SD = 8.23) years of teaching experience, worked in urban academic hospitals (64.7%) and had performed 643 (SD = 467) robotic operations at the time of interviews. Emphasis on efficiency (or lack thereof) surfaced across three main themes: overall case progression, robotic capabilities, and instrumentation. Experts verbally rewarded purposeful and "ergonomically sound" movements while language reflecting impatience with repetitive and indecisive movements was attributed to presumed inexperience. Efficient robotic capabilities included enhanced visualization, additional robotic arms to improve exposure, and wristed instruments. Finally, experts discussed instrument selection with regards to energy modality, safety features, cost, and versatility.

CONCLUSION

This study highlights three areas for improved efficiency: case progression, robotic capabilities, and instrumentation. Development of education materials within these themes could help surgical educators overcome one of robotic technology's persistent challenges.

Transforming Surgical Education through a Resident Robotic Curriculum

Objective

Here, we describe a systematic approach to design, implement, and assess a robotic surgery curriculum for surgical residents. By describing our process, including identifying and addressing institutional challenges, we illustrate successful development of a robust curriculum.

Summary Background Data

As robotic-assisted surgeries increase, educational challenges have emerged and illustrate an alarming impact on medical training. Robotic curricula are frequently grounded in the industry's educational materials resulting in a variety of existing resident curricula that lack cognitive components and critical evaluation. As such, surgical educators struggle to identify the curricular restructuring needs that likely accompany emerging technologies. It is essential to develop a curricular framework for the surgical education community to approach the ongoing and inevitable integration of new technologies.

Methods

Our process parallels the widely accepted approach to curricular development in medical education described by Kern et al. Using this 6-step model, we describe derivation of a curriculum that was data driven, features multimodal educational strategies, and provides documentation methods that allow for continued evaluation and assessment at the individual and departmental level.

Results

This study highlights the systematic process of design, implementation and assessment of a robotic surgery curriculum for surgical residents. Built on a robust national and local needs assessment, and further strengthened by preemptive identification of institutional challenges, this curricular model includes a structured documentation system that allows for ongoing evaluation, assessment, and monitoring of curricular progress.

Conclusions

We illustrate a robustly built curricular structure that can be adopted, adapted, and successfully implemented at other training institutions around the world.

Learning through the senses

A robotic teaching session: separating tool from technique to emphasize a cognitive focused teaching environment

Most robotic curriculum requires simulation on a console prior to operative exposure. This practice does not permit experiencing the physical collisions with the robotic tools, which occurs during surgery. We designed and evaluated an innovative curriculum to address cognitive components and trouble-shoot robotic collisions when the surgeon lacks haptic feedback. We adapted our previous curriculum, designed to teach and document proficiency of robotic docking and instrument exchange, to include robotic collisions. Participants received a 10-min, didactic presentation describing finger grips, internal and external collisions, and instruction on how to trouble-shoot each type. Residents worked in pairs, one at the console and the other at bedside, to complete two simulation exercises. Participants manipulated the robot to determine how best to resolve the situations. Residents completed retrospective post-course surveys and instructors completed a final survey. For comparison, non-participants, PGY-matched surgical trainees, also completed a survey. All participants demonstrated proficiency in docking and instrument exchange. Compared to pre-session, post-session knowledge and confidence improved in five domains reflecting session objectives (p < 0.05). Participants could list and troubleshoot collisions more than the non-participant matched peers (p < 0.05). Instructors supported the additional collision components, but noted learners needed more time. Two of three non-participants expressed interest in a teaching session to address these components. Collisions occur using robotic technology and rarely get addressed in surgical training. We describe an opportunity for surgeons to trouble-shoot robotic collisions in a safe, simulated environment. This easily transferable curriculum represents one of the first industry-independent robotic teaching sessions for surgical trainees.
