Background Previous studies have indicated that fiberoptic orotracheal intubation (FOI) skills can be learned outside the operating room. The purpose of this study was to determine which of two educational interventions allows learners to gain greater capacity for performing the procedure. Methods Respiratory therapists were randomly assigned to a low-fidelity or high-fidelity training model group. The low-fidelity group was guided by experts, on a nonanatomic model designed to refine fiberoptic manipulation skills. The high-fidelity group practiced their skills on a computerized virtual reality bronchoscopy simulator. After training, subjects performed two consecutive FOIs on healthy, anesthetized patients with predicted "easy" intubations. Each subject's FOI was evaluated by blinded examiners, using a validated global rating scale and checklist. Success and time were also measured. Results Data were analyzed using a two-way mixed design analysis of variance. There was no significant difference between the low-fidelity (n = 14) and high-fidelity (n = 14) model groups when compared with the global rating scale, checklist, time, and success at achieving tracheal intubation (all P = not significant). Second attempts in both groups were significantly better than first attempts (P < 0.001), and there was no interaction between "fidelity of training model" and "first versus second attempt" scores. Conclusions There was no added benefit from training on a costly virtual reality model with respect to transfer of FOI skills to intraoperative patient care. Second attempts in both groups were significantly better than first attempts. Low-fidelity models for FOI training outside the operating room are an alternative for programs with budgetary constraints.

AbstractTherapeutic interventions have not yet been shown to demonstrate restorative effects for declining long-term memory (LTM) that affects many healthy older adults. We developed a virtual reality (VR) spatial wayfinding game (Labyrinth-VR) as a cognitive intervention with the hypothesis that it could improve detailed, high-fidelity LTM capability. Spatial navigation tasks have been used as a means to achieve environmental enrichment via exposure to and learning about novel and complex information. Engagement has been shown to enhance learning and has been linked to the vitality of the LTM system in the brain. In the current study, 48 older adults (mean age 68.7 ± 6.4 years) with average cognitive abilities for their age were randomly assigned to 12 h of computer game play over four weeks in either the Labyrinth-VR or placebo control game arms. Promptly before and after each participant’s treatment regimen, high-fidelity LTM outcome measures were tested to assess mnemonic discrimination and other memory measures. The results showed a post-treatment gain in high-fidelity LTM capability for the Labyrinth-VR arm, relative to placebo, which reached the levels attained by younger adults in another experiment. This novel finding demonstrates generalization of benefits from the VR wayfinding game to important, and untrained, LTM capabilities. These cognitive results are discussed in the light of relevant research for hippocampal-dependent memory functions.

Immersive Technologies

Virtual environments and immersive technologies are growing in popularity for human factors purposes. Whether it is training in a low-risk environment or using simulated environments for testing future automated vehicles, virtual environments show promise for the future of our field. The purpose of this session is to have current human factors practitioners and researchers demonstrate their immersive technologies. This is the eighth iteration of the “Me and My VE” interactive session. Presenters in this session will provide a brief introduction of their virtual reality, augmented reality, or virtual environment work before engaging with attendees in an interactive demonstration period. During this period, the presenters will each have a multimedia display of their immersive technology as well as discuss their work and development efforts. The selected demonstrations cover issues of designing immersive interfaces, military and medical training, and using simulation to better understand complex tasks. This includes a mix of government, industry, and academic-based work. Attendees will be virtually immersed in the technologies and research presented allowing for interaction with the work being done in this field.

The Face

Objective Otologic diseases are common in all age groups and can significantly impair the function of this important sensory organ. To make a correct diagnosis, the correct handling of the otoscope and a correctly performed examination are essential. A virtual reality simulator could make it easier to teach this difficult-to-teach skill. The aim of this study was to assess the face, content, and construct validity of the novel virtual reality otoscopy simulator and the applicability to otologic training. Study Design Face and content validity was assessed with a questionnaire. Construct validity was assessed in a prospectively designed controlled trial. Setting Training for medical students at a tertiary referral center. Method The questionnaire used a 6-point Likert scale. The otoscopy was rated with a modified Objective Structured Assessment of Technical Skills. Time to complete the task and the percentage of the assessed eardrum surface were recorded. Results The realism of the simulator and the applicability to medical training were assessed across several items. The ratings suggested good face and content validity as well as usefulness and functionality of the simulator. The otolaryngologists significantly outperformed the student group in all categories measured (P < .0001), suggesting construct validity of the simulator. Conclusion In this study, we could demonstrate face, content, and construct validity for a novel high-fidelity virtual reality otoscopy simulator. The results encourage the use of the otoscopy simulator as a complementary tool to traditional teaching methods in a curriculum for medical students.

Physician Relationship

AbstractEmpathy is the basis of a patient-physician relationship; however, this is being lost by students throughout medical training. Immersive virtual reality that allows individuals to viscerally experience anything from another person’s point of view has the potential to reverse the erosion of empathy and improve clinical practices.
