Virtual reality simulation increases Chinese physicians' and lab technicians' familiarity and confidence regarding proper clinical wastes segregation/disposal: A 2-year pilot study

Abstract

Although they receive regular training, the survey we administered to our junior physicians and lab technicians revealed that they lack familiarity and confidence regarding the proper segregation/disposal of clinical wastes. In this pilot prospective study, carried out between September 2017 and September 2019, we developed a virtual reality (VR) simulation and integrated it into the steps of Gangen's training flow. Next, we analysed objective performance, recorded by the App in the VR system as well as the subjective self-assessments of 96 junior physicians and lab technicians after two practices of VR games. Before receiving training, lab technicians' self-assessed familiarity and confidence regarding proper clinical wastes segregation/disposal were higher than among physicians. Compared with the first VR game, we noted greater improvement in accuracy as well as a higher percentage of shortened time to complete 10 actions of segregation/disposal of VR clinical wastes, among junior physicians/male trainees, that of junior lab technicians/female trainees in the second VR game. Most of the trainees (81%-88%) reported that they found the VR game-based training to be useful, in contrast to poster-mass media-based training. Our initial positive results indicated the possibility of applying this VR game-based simulation system to regular institution-wide staff education in future.
