Development of simulated arthroscopic skills.

ABSTRACT:

Background and purpose

Previous studies have shown that there is a correlation between arthroscopic experience and performance on a virtual-reality (VR) unit. We analyzed the development inexperienced surgeons went through during VR training of shoulder arthroscopy.

Methods

14 inexperienced surgeons from Silkeborg Regional Hospital were randomized into an intervention group and a control group. 7 experienced surgeons constituted another control group. All were tested twice on insightMIST-an advanced arthroscopic VR trainer-within a period of 6-15 days. The intervention group also received a 5-hour training program on the VR unit.

Results

The average time for the arthroscopy in the intervention group was reduced from 720 (SD 239) seconds to 223 (SD 114) seconds (p = 0.03 compared to the inexperienced control group). Distance travelled by the camera was reduced from 367 (SD 151) cm to 84 (SD 44) cm in the intervention group (p = 0.02 compared to the inexperienced control group). Depth of collisions was also significantly reduced, whereas distance travelled by the probe and number of collisions were improved in the intervention group, although not statistically significantly.

Interpretation

VR training is a possible way for young and inexperienced surgeons to achieve basic navigation skills necessary to perform arthroscopic surgery. Further studies regarding the transferability of the skills acquired on the VR unit to the operating theater are desirable.

Project description:Background:The aim of this study was to evaluate exercise physiology students' perceptions of two simulation-based learning modules focused on communication and interpersonal skills during history taking. Methods:A prospective, repeated-measures cohort study was conducted with 15 participants. The study evaluated two simulation-based learning modules in a 1-year Graduate Diploma of Exercise Science program. Surveys were administered at four time points: prior to each module and following each module. Students rated their confidence in communication and history taking, and perception of preparedness for practice, motivation for learning, and benefits of undertaking simulation-based learning. Quantitative data were analyzed descriptively and by using repeated measures tests. Qualitative data underwent thematic analyses. Results:Students reported a significant improvement in their confidence in communication (P?=?0.043) and in two parameters related to history taking (P?=?0.034 and 0.035) following the completion of the two modules. There was 96% agreement that the simulation-based learning better prepared students for practice as an exercise physiologist. Significant changes occurred in all aspects of motivation for learning (P ranging from <?0.001 to 0.036) except for usefulness, where there was a ceiling effect (medians of 7 on a 7-point scale). Qualitative analysis demonstrated benefit to participants around themes of experiential learning, realism, opportunity to develop clinical skills, and debriefing. Students also made suggestions with respect to the activity structure of the simulation-based learning modules. Conclusions:The results of this study indicated that simulation-based learning employing SPs increased the confidence and preparedness of exercise physiology students for conducting history taking, a requisite exercise physiology skill. Future studies should include behavioral measures of skill attainment and include follow-up evaluation to appraise the application of these skills into clinical practice.

Project description:PurposeTo compare the effectiveness, in comparison to a control group (C), of module-based training (MBT) and traditional learning (TL) as a means of acquiring arthroscopic skills on an arthroscopic surgery simulator.MethodsThirty health sciences students with no previous arthroscopy experience were recruited and randomized into 1 of 3 groups: MBT, TL, or C (1:1:1 ratio). Participants in MBT were required to independently practice on a VirtaMed ArthroS simulator (VirtaMed AG, Zurich, Switzerland) for a minimum of 2 hours per week, whereas TL received one-on-one coaching by a senior orthopaedic resident for 15 minutes per week. The control group received no training. All groups were assessed at baseline and at 4 weeks based on objective measures generated by the surgical simulator (procedure time, camera path length, meniscus cutting score, detailed visualization, safety score and total score), and subjective ratings scales (Objective Assessment of Arthroscopic Skill [OAAS] global assessment form, and Competency-Based Assessment form).ResultsParticipants in the MBT group trained on average 113 min/week whereas the TL group trained on average 24 min/week. Three-way repeated-measures analysis of variance showed significant group by time interactions for procedure time (P = .006), camera path length (P = .008), safety score (P = .013), total score (P = .003), OAAS form (P < .001), and Competency-Based Assessment form (P < .001). MBT group was superior to C group for procedure time (P = .02), camera path length (P = .003), total score (P = .004), and OAAS form (P = .021), but there were no significant post-hoc differences between MBT and TL groups, or TL and C groups after Bonferroni correction. Total practice time explained 37.5% of the final simulator total score variance.ConclusionsKnee arthroscopy simulation training with self-learning modules can improve skills in areas such as procedure time, camera path length, and total score in untrained participants compared with a control group.Clinical relevanceModule-based simulation training provides additional training time and improves technical skills in naive health science students. It is hoped that this effect can be preserved and applied to junior resident developing in a busy residency program.
