Remote training in laparoscopy: a randomized trial comparing home-based self-regulated training to centralized instructor-regulated training.

ABSTRACT:

Background

Simulation-based surgical training (SBST) is key to securing future surgical expertise. Proficiency-based training (PBT) in laparoscopy has shown promising results on skills transfer. However, time constraints and limited possibilities for distributed training constitute barriers to effective PBT. Home-based training may provide a solution to these barriers and may be a feasible alternative to centralized training in times of assembly constraints.

Methods

We randomly assigned first-year trainees in abdominal surgery, gynecology, and urology to either centralized instructor-regulated training (CIRT) or home-based self-regulated training (HSRT) in laparoscopy. All participants trained on portable box trainers providing feedback on metrics and possibility for video reviewing. Training in both groups was structured as PBT with graded proficiency exercises adopted from the Fundamentals of Laparoscopic Surgery (FLS). The HSRT group trained at home guided by online learning materials, while the CIRT group attended two training sessions in the simulation center with feedback from experienced instructors. Performance tests consisted of hand-eye and bimanual coordination, suture and knot-tying, and FLS exercises. We analyzed passing rates, training time and distribution, and test performances.

Results

Passing rates were 87% and 96% in the CIRT and HSRT group, respectively. HSRT facilitated distributed training and resulted in greater variation in training times. Task times for hand-eye and bimanual coordination were significantly reduced between pretest and posttest in both groups. Trainees maintained their posttest performances at the 6-month retention test. Our analyses revealed no significant inter-group differences in performances at pretest, posttest, or retention test. Performance improvements in the two groups followed similar patterns.

Conclusion

CIRT and HSRT in laparoscopy result in comparable performance improvements. HSRT in laparoscopy is a feasible and effective alternative to CIRT when offered inside a supportive instructional design. Further research is needed to clarify trainees' preferences and explore facilitators and barriers to HSRT.

Project description:BackgroundInexperienced operating assistants are often tasked with the important role of handling camera navigation during laparoscopic surgery. Incorrect handling can lead to poor visualization, increased operating time, and frustration for the operating surgeon-all of which can compromise patient safety. The objectives of this trial were to examine how to train laparoscopic camera navigation and to explore the transfer of skills to the operating room.Materials and methodsA randomized, single-center superiority trial with three groups: The first group practiced simulation-based camera navigation tasks (camera group), the second group practiced performing a simulation-based cholecystectomy (procedure group), and the third group received no training (control group). Participants were surgical novices without prior laparoscopic experience. The primary outcome was assessment of camera navigation skills during a laparoscopic cholecystectomy. The secondary outcome was technical skills after training, using a previously developed model for testing camera navigational skills. The exploratory outcome measured participants' motivation toward the task as an operating assistant.ResultsThirty-six participants were randomized. No significant difference was found in the primary outcome between the three groups (p = 0.279). The secondary outcome showed no significant difference between the interventions groups, total time 167 s (95% CI, 118-217) and 194 s (95% CI, 152-236) for the camera group and the procedure group, respectively (p = 0.369). Both interventions groups were significantly faster than the control group, 307 s (95% CI, 202-412), p = 0.018 and p = 0.045, respectively. On the exploratory outcome, the control group for two dimensions, interest/enjoyment (p = 0.030) and perceived choice (p = 0.033), had a higher score.ConclusionsSimulation-based training improves the technical skills required for camera navigation, regardless of practicing camera navigation or the procedure itself. Transfer to the clinical setting could, however, not be demonstrated. The control group demonstrated higher interest/enjoyment and perceived choice than the camera group.

Project description:IntroductionSimulation training programs are essential for novice surgeons to acquire basic experience to master laparoscopic skills. However, current state-of-the-art laparoscopy simulators are still expensive, limiting the accessibility to practical training lessons. Furthermore, training is time intensive and requires extensive spatial capacity, limiting its availability to surgeons. New laparoscopic simulators offer a cost-effective alternative, which can be used to train in a digital environment, allowing flexible, digital and personalized laparoscopic training. This study investigates if training on low-cost simulators in a digital environment is comparable to in-person training formats.Materials and methodsFrom June 2023 to December 2023, 40 laparoscopic novices participated in this multi-center, prospective randomized controlled trial. All participants were randomized to either the ‟distance" (intervention) or the "in-person" (control) group. They were trained in a standardized laparoscopic training curriculum to reach a predefined level of proficiency. After completing the curriculum, participants performed four different laparoscopic tasks on the ForceSense system. Primary endpoints were overall task errors, the overall time for completion of the tasks, and force parameters.ResultsIn total, 40 laparoscopic novices completed digital or in-person training. Digital training showed no significant differences in developing basic laparoscopic skills compared to in-person training. There were no significant differences in median overall errors between both training groups for all exercises combined (intervention 3 vs. control 4; p value = 0.74). In contrast, the overall task completion time was significantly lower for the group trained digitally (intervention 827.92 s vs. control 993.42; p value = 0.015). The applied forces during the final assessment showed no significant differences between both groups for all exercises. Overall, over 90% of the participants rated the training as good or very good.ConclusionOur study shows that students that underwent digital laparoscopic training completed tasks with a similar number of errors but in a shorter time than students that underwent in-person training. Nevertheless, the best strategies to implement such digital training options need to be evaluated further to support surgeons' personal preferences and expectations.

Project description:AimsThe aim of this study was to investigate whether shifting the focus to solution orientation and developing coping strategies for common errors could increase the efficiency of laparoscopic training and influence learning motivation. The concept of coping has been particularly defined by the psychologist Richard Lazarus [Lazarus and Folkman in Stress, appraisal, and coping, Springer publishing company, New York, 1984]. Based on this model, we examined the use of observational learning with a coping model for its effectiveness as a basic teaching model in laparoscopic training.Methods55 laparoscopically naive medical students learned a standardized laparoscopic knot tying technique with video-based instructions. The control group was only offered a mastery video that showed the ideal technique and was free from mistakes. The intervention group was instructed on active error analysis and watched freely selectable videos of common errors including solution strategies (coping model) in addition to the mastery videos.ResultsThere was no statistically significant difference between the intervention and control groups for number of knot tying attempts until proficiency was reached (18.8 ± 5.5 vs. 21.3 ± 6.5, p = 0.142). However, there was a significantly higher fraction of knots achieving technical proficiency in the intervention group after first use of the coping model (0.7 ± 0.1 vs. 0.6 ± 0.2, p = 0.026). Additionally, the proportion of blinded attempts that met the criteria for technical proficiency was significantly higher for the intervention group at 60.9% vs. 38.0% in control group (p = 0.021). The motivational subscore "interest" of the validated score on current motivation (QCM) was significantly higher for the intervention group (p = 0.032), as well as subjective learning benefit (p = 0.002) and error awareness (p < 0.001).ConclusionUsing video-based learning of coping strategies for common errors improves learning motivation and understanding of the technique with a significant difference in its qualitative implementation in laparoscopy training. The ability to think in a solution-oriented, independent way is necessary in surgery in order to recognize and adequately deal with technical difficulties and complications.
