“…The results of our study demonstrated significantly improved levels of performance for all skill sets for novice surgical residents trained on LAP Sim for minimally invasive surgical procedures. These results were in alignment with previous observational and interventional studies conducted to assess the role of VR based surgical training 7,[12][13][14][15] . In Buescher et al, (2017), there was significant decrease in operation time (p<0.01) at the time of training and also after six weeks indicating skill retention 12 .…”

Objective: To assess the impact of laparoscopic simulation training on surgical skills of trainee surgeons. Study Design: Comparative prospective study. Place and Duration of Study: Jinnah Sindh Medical University Karachi, for one month October 2019. Methodology: Total thirty surgical trainees of FCPS year four (R4) were studied. The cases group (fifteen trainees) were given one month laparoscopy training on a LAP Simulator (LAPSim), surgical science Sweden) and the control group (fifteen trainees) were not trained. Their laparoscopic skills were then compared. Objective Structured Assessment of Technical Skills (OSATS) specific and general was used to assess their performance. Data was entered and analyzed using SPSS-23. Results: On LAP Sim Scoring, post-test scores were significantly better than pre-test for all skills in the trainedresidents (p<0.01 for all subscales) and total post-test score was also significantly better for trained surgeonsas compared to untrained (77.45 ± 7.78 vs. 31.70 ± 2.48; p<0.01). On Objective Structured Assessment of Technical Skills for specific tasks, post-test scores were significantly better than pre-test for all tasks in the cases (p<0.01 for all subscales) and for none in the controls. On Objective Structured Assessment of Technical Skills general, posttest scores were significantly better than pre-test for all tasks in the cases (p<0.01 for all subscales) and for clip application (p<0.01) and suturing with intracorporeal knot tying (p<0.01) in the controls. Conclusion: This study demonstrated significantly improved levels of performance for all skill sets for novicesurgical residents trained on LAP Sim for minimally invasive surgical procedures.

“…Previous comparisons of instructor-regulated learning and directed SRL in simulation-based training indicate the benefits of SRL and emphasize that trainees need evidence-based educational supports for SRL [40][41][42]. Goal lists, video instructions, video reviews, and computer-generated feedback have proven effective as educational supports for SBST [30,32,40,[43][44][45]. To date, we are not aware of studies that applied all of these educational supports in a home-based PBT program in laparoscopy.…”

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

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.

Automatic and Objective Assessment of Motor Skills Performance in Flexible Bronchoscopy

et al. 2021

Background: Motor skills have been identified as a useful measure to evaluate competency in bronchoscopy. However, no automatic assessment system of motor skills with a clear pass/fail criterion in flexible bronchoscopy exists. Objectives: The objective of the study was to develop an objective and automatic measure of motor skills in bronchoscopy and set a pass/fail criterion. Methods: Participants conducted 3 bronchoscopies each in a simulated setting. They were equipped with a Myo Armband that measured lower arm movements through an inertial measurement unit, and hand and finger motions through electromyography sensors. These measures were composed into an objective and automatic composite score of motor skills, the motor bronchoscopy skills score (MoBSS). Results: Twelve novices, eleven intermediates, and ten expert bronchoscopy operators participated, resulting in 99 procedures available for assessment. MoBSS was correlated with a higher diagnostic completeness (Pearson’s correlation, r = 0.43, p < 0.001) and a lower procedure time (Pearson’s correlation, r = −0.90, p < 0.001). MoBSS was able to differentiate operator performance based on the experience level (one-way ANOVA, p < 0.001). Using the contrasting groups’ method, a passing score of −0.08 MoBSS was defined that failed 30/36 (83%) novice, 5/33 (15%) intermediate, and 1/30 (3%) expert procedures. Conclusions: MoBSS can be used as an automatic and unbiased assessment tool for motor skills performance in flexible bronchoscopy. MoBSS has the potential to generate automatic feedback to help guide trainees toward expert performance.
