Design, validation and implementation of a virtual reality high fidelity laparoscopic appendicectomy curriculum
INTRODUCTION: The treatment for acute appendicitis is laparoscopic appendicectomy (LA), usually performed by trainees who face significant challenges to training. Simulation curricula are being increasingly utilised and optimised to accelerate learning and improve skill retention in a safe environment. The aim of this study is to produce and implement a virtual reality (VR) curriculum for laparoscopic appendicectomy (LA) on the high-fidelity LAP Mentor VR simulator. METHODOLOGY: Performance data of randomised experts and novices were compared to assess the construct validity of the LAP Mentor basic skills (BS) and LA modules. Face validity of the simulator and module was assessed by questionnaire. These results informed the construction of a VR LA curriculum on an evidence-based theoretical framework. The curriculum was implemented and evaluated by analysis of participant diaries. RESULTS: Thirty-five novices and 25 experienced surgeons performed either BS, five LA procedural tasks or the LA full procedure. Both modules demonstrated construct validity. The LA module was deemed moderately realistic and useful for developing laparoscopic psychomotor skills. Seven novice trainees completed the new LA curriculum (three others dropped out). Analysis of participants diaries revealed the presence of frustration, the benefits of feedback sessions and the advantages and pitfalls of open access. DISCUSSION: Evaluations of the implementation of similar curricula are rare and participant diaries led to critical insights. The curriculum was difficult and sometimes frustrating, mitigated by rewarding experiences and coaching. The latter facilitated deliberate practice. Scheduling issues were mitigated by open access. Limitations of the curricula include the invariability in the presentation of appendicitis, and the reason for dropouts are not known. CONCLUSION: Several BS and all LA tasks are construct-valid. A new VR LA curriculum was implemented and analysis of participant diaries yielded critical insights into real-world ...
