The Present and Future of Virtual Reality in Medical Education: A Narrative Review

Virtual reality (VR) uses computer-generated and three-dimensional environments to create immersive experiences through the use of interactive devices that simulate virtual environments in many forms, such as 3D, screen-based, or room-based. Users can engage in the environment with objects, characters, and scenes, making individuals assume they are experiencing a real-life scenario. VR has been adopted across medical and nursing fields to supplement clinically relevant and practical teaching. However, the effectiveness of this interactive form of learning has come a long way with improvements in accessibility, cost, and technicalities. The immersive simulated environment that VR has to offer today initially began with screen-based learning and then the 360-video method. These previously sought-out methods were eventually found to disconnect the students from engaging in the learning environment that present-day VR systems are designed to provide. Interactive VR offers a dynamic platform for medical training. These simulations benefit the learner by allowing them to interact within case scenarios and virtual wards, as well as with patients, colleagues, and relatives. To mimic real-life encounters, the student can take a patient's history and physical exam, investigate, diagnose, and provide treatment. The simulated patient can express emotions, concerns, and signs of a poor state of health. All these factors play into a healthcare provider's competency to think critically and clinically in decision-making. This practice is now being used in many surgical programs and medical education curricula. The use of simulation in VR is continuously being proven to decrease injury, increase operation speed, and improve overall outcomes in patient-centered care. VR simulation differs from in-person simulation training in that the VR modality of learning is more accessible and replicable than the latter. By comparing research studies and reviews of medical programs that incorporated VR into their curricula, we were able to assess the state of VR in medical education and where this technology could lead to future implementation in medical programs. Our review aimed to give insight into the existing evidence, the gaps in the use of VR in medical education, and the potential benefits this modality of learning can have going forward in this field of study. Medical students have demonstrated significantly enhanced knowledge gain when using immersive interactive VR over screen-based learning. Given the improvements in students' performance due to these dynamic and collaborative learning experiences, immersive VR training will become a standard in the development of clinical skills and ensure patient safety. Although the emphasis on empathy began later in the journey of gaining VR as a part of medical education, there is a need to gain those skills as early as possible in medical school. Implementing the use of VR as a supplement in medical education allows students to practice simulated patient encounters along with an array of different academic endeavors. By doing so, students will gain competency and confidence as they encounter patients during their clinical rotations and clinical practice.
