Utilizing eye tracking to assess medical student non-technical performance during scenario-based simulation: results of a pilot study.
The purpose of this study was to determine if eye tracking (ET) metrics are associated with non-technical skills (NTS) performance. Participants wore a mobile ET system and participated in two patient care simulations in which they managed a deteriorating patient. Preliminary data suggests that visual attention on the patient was negatively associated with NTS and may indicate poor comprehension of the patient's status due to heightened cognitive load. The authors concluded that researchers and educators should consider using ET in future work to evaluate and provide feedback on their NTS.

Validation of a simulation-based resuscitation curriculum for maternal cardiac arrest.
The purpose of this study was to evaluate the knowledge, skills, and self-efficacy of health care participants completing a simulation-based blended learning training curriculum on managing maternal medical emergencies and maternal cardiac arrest. The study included a formative assessment of the Obstetric Life Support curriculum. The training consisted of self-guided pre-course work and an instructor-led simulation course using a customized low-fidelity simulator. Eighty-five participants consented to participation in the training (out of 88 invited); 77 participants completed the training over eight sessions. The study found that at baseline, less than 50% of participants were able to achieve a passing score on the cognitive assessment. After the course, mean cognitive assessment scores improved by 13 points, from 69.4% at baseline to 82.4% after the course. The researchers observed significant improvements in participant self-efficacy, and 92.6% of participants agreed or strongly agreed that the course met its educational objectives.

Operating room design using agent-based simulation to reduce room obstructions.
The purpose of this study was to improve the safety of clinical care provided in operating rooms (ORs) by examining wats in which characteristics of both the procedure and the physical environment affect surgical team movement and contacts. Researchers video recorded staff movements during surgical procedures, then divided the OR into multiple zones and analyzed the frequency and duration of movement from origin to destination. Results showed that OR size, the circulating nurse workstation location, and team size significantly affected surgical team contacts; two- and three-way interactions between staff, procedure type, table orientation, and workstation location also significantly affected contacts. Implications of these findings for OR managers and for future research about designing future ORs are discussed.

A novel patient-specific computational fluid dynamics study of the activation of primary collateral pathways in the Circle of Willis during vasospasm.
This study presented a novel technique to create patient-specific computational fluid dynamics simulations of the Circle of Willis (a redundant network of blood vessels that perfuses the brain) before and during vasospasm. Computed tomographic angiography scans are segmented to model the vasculature, and transcranial Doppler ultrasound measurements of blood flow velocity are applied as boundary conditions. The authors stated that this analysis can be applied in future to a cohort of patients to investigate the relationship between the locations and severities of vasospasm, anatomical variability in individuals’ Circle of Willis, and the activation of collateral pathways.

First Responder Virtual Reality Simulator to train and assess emergency personnel for mass casualty response.
This paper describes the First Responder Virtual Reality Simulator, a high-fidelity, fully immersive, automated, programmable virtual reality (VR) simulation designed to train frontline responders to treat and triage victims of mass casualty incidents. First responder trainees wear a wireless VR head-mounted display linked to a compatible desktop computer. Autonomous, interactive victims who are programmed to simulate individuals with injuries consistent with an explosion in an underground space are used. The trainees are armed with a virtual medical kit, who are then tasked with triaging and treating the victims on the scene. Increased challenges can be added such as increasing the environmental chaos, adding patients, or increasing the acuity of patient injuries.
