RESUMEN
BACKGROUND: Gaining familiarity with bedside procedures during medical school is essential for preparing medical students for intern year. However, this is often not a core component of undergraduate medical education, and students often feel unprepared to perform bedside procedures upon graduation from medical school. Extended reality technologies have rapidly developed in the past few years, become more accessible, and show great promise in education, most recently in healthcare. We aim to show the feasibility and usability of a mixed-reality lumbar puncture simulated experience. METHODS: We created the mixed-reality simulation by filming a procedure conducted by an expert on a lumbar puncture simulator from the first-person view. We performed a study to assess the feasibility and usability of mixed-reality lumbar puncture training compared with traditional faculty-led high-fidelity mannikin-based simulation training. Fourth-year medical students were randomly selected to participate in the mixed-reality lumbar puncture training. Students watched the virtual first-person teaching via a virtual reality headset while mimicking hand movements on a lumbar puncture mannikin. Faculty taught students in the traditional high-fidelity group in small groups before practicing on the high-fidelity manikin. Students in both groups then performed the procedure entirely with performance assessed via a standardized checklist. Number of attempts to achieve a predetermined minimum passing score were recorded, and students were also surveyed regarding their experience with both simulations. RESULTS: Fifty-nine percent of students felt comfortable using mixed reality as a training modality with less than 6% having any prior extended reality experience. More than 55% felt the mixed-reality experience was as effective as the traditional high-fidelity simulation training. Many students (72%) desired more mixed-reality opportunities. In terms of performance, 58.8% of students in the mixed-reality group vs 65.5% in the traditional group completed the checklist in 1 attempt (P = .79). CONCLUSIONS: We demonstrate that mixed reality is an acceptable and effective modality to train health care professionals in lumbar punctures with opportunities to further enhance the immersive learning experience.
RESUMEN
BACKGROUND: Recognizing and attempting management of patients with urgent or emergent conditions is one of the Association of American Medical Colleges Core Entrustable Professional Activities (#10) and a skill desired of new interns. However, given the acuity of these patient conditions, medical students often struggle to gain experience in these situations. Virtual reality could help fill this void while lowering costs and resources compared with high-fidelity simulation. METHODS: We converted a high-fidelity chest pain simulation case to virtual reality format utilizing short video clips filmed with a 360-degree camera and superimposed menus of options at decision points. This virtual reality simulation was offered to fourth-year medical students during their transition to residency course in the spring of 2023. Students were offered a post-survey on the simulation. RESULTS: There were 47 fourth-year students that completed the virtual reality simulation; 41 completed the post-survey (response rate 87.2%). Over 90% of the students agreed or strongly agreed with the following statements: the virtual reality simulation was a valuable part of the transition to residency course, the virtual reality case was similar to what they will face as an intern, and they would like to have more virtual reality simulations earlier in the fourth year; 85.4% agreed or strongly agreed that the virtual reality simulation helped prepare them for the first few days of intern year. CONCLUSIONS: We demonstrated that virtual reality is an acceptable, cost-effective, and feasible modality to teach medical students how to recognize and attempt management of urgent clinical situations (Core Entrustable Professional Activity 10).
