简要总结
Background and hypothesis:
Virtual reality (VR) training in minimal invasive surgery (MIS) is known to be feasible and beneficial in surgical residency. Research on stress- coping in surgical trainees indicate an additional impact of soft skills on VR- performance. Thus to hypothesize soft skills predicting surgical performance in a VR- setting.
Method:
A prospective randomized controlled single center educational trial was carried out to evaluate the impact of structured VR- training and defined soft skills such as self- efficacy, stress- coping and motivation on VR- performance.
详细描述
Method:
Eligibility criteria were surgical residency not exceeding the first year of surgical training, a limited experience in MIS and informed consent to the study procedures including an anonymized publication of the study data. Limited experience in MIS was defined as camera navigation in laparoscopic cholecystectomies only.
Fifty residents were enrolled and prospectively randomized to either three months of structured VR- training or no training. Every participant underwent a basic VR- skills assessment and a serial assessment of defined soft skills including self- efficacy, stress- coping and motivation prior to randomization.
Basic VR- skills were measured within seven modules of the VR- simulator LapSim® (Surgical Science, Goteborg, Sweden) including "camera and instrument navigation", "coordination", "grasping", "lifting and grasping", "clip applying" and "diathermy cutting". Each module had to be performed in two levels of difficulty- medium and hard. Means of defined parameters of VR- performance were generated. Defined parameters of VR- performance comprised "time to complete task", "economy of instrument motion" and "tissue damage".
Serial assessment of defined soft skills comprised standardized psychological paper- pencil questionnaires regarding self efficacy (GSE), stress coping (SVF 78) and motivation (QCM).
