“…Although this characteristic is more evident in simulations in cadavers, it can also occur in synthetic simulators. Some commercial synthetic models for laparoscopy have hardened tissue consistency, requiring sudden movements to perform dissection maneuvers 23 .…”

Objective: to validate a lumbar spine endoscopic flavectomy simulator using the construct method and to assess the acceptability of the simulator in medical education. Methods: thirty medical students and ten video-assisted surgery experienced orthopedists performed an endoscopic flavectomy procedure in the simulator. Time, look-downs, lost instruments, respect for the stipulated edge of the ligamentum flavum, regularity of the incision, GOALS checklist (Global Operative Assessment of Laparoscopic Skills), and responses to the Likert Scale adapted for this study were analyzed. Results: all variables differed between groups. Procedure time was shorter in the physician group (p < 0.001). Look-downs and instrument losses were seven times greater among students than physicians. Half of the students respected the designated incision limits, compared to 80% of the physicians. In the student group, about 30% of the incisions were regular, compared to 100% in the physician group (p < 0.001). The physicians performed better in all GOALS checklist domains. All the physicians and more than 96% of the students considered the activity enjoyable, and approximately 90% believed that the model was realistic and could contribute to medical education. Conclusions: the simulator could differentiate the groups’ experience level, indicating construct validity, and both groups reported high acceptability.

Background: The use of simulation-based training tools within surgery is rapidly increasing and has demonstrated promising alternative training modalities allowing for surgical skill enhancement despite workplace pressures. Whilst many simulators have been investigated for their validity, this has not been demonstrated across all domains. This review aims to identify the status of simulation-based training tools in general surgery in the current literature, assess their validity and determine their effectiveness. Methods: OVID Medline and Embase databases were searched for English language articles describing the validation of a simulator for general surgery-specific procedures between 2000 and 2020. Studies were reviewed according to Messick's validity framework and rated in each domain. A modified version of translational outcomes described by McGaghie et al. were used to determine the level of effectiveness (LoE) of each simulator. Results: A total of 9653 articles were screened and 97 articles were identified to determine the LoE of the simulators. The highest rating for each validity domain was achieved by 30 models/training courses for content validity, 48 for response processes, 5 for internal structure, 40 for relations to other variables and 10 for consequences. Two simulators gained LoE >2 showing skill transfer downstream of the simulator. Conclusion: The varying ratings across each validity domain for the simulators show that evidence of complete validity is poor. Only 2 simulators were awarded LoE >2, indicating further research is needed in order to substantiate the use of simulation in improving patient outcomes. Highlights
