Applying simulation learning theory to identify instructional strategies for Generation Z emergency medicine residency education.

Introduction: Generation Z learners are entering emergency medicine (EM) residency training, bringing unique learning preferences that influence their engagement with residency education. To optimally teach and motivate this incoming generation of learners, EM educators must understand and adapt to the changing instructional landscape. Methodology: The Simulation Leaders Advancing the Next Generation in Emergency Medicine (SLANG-EM) Workgroup was created to identify effective educational strategies for Generation Z learners entering EM. Members were faculty in the Society for Academic Emergency Medicine (SAEM) Simulation Academy, well versed in learning theory supporting simulation-based education (SBE) and actively involved in EM residency education. Unique treatment/analysis: Through primary and secondary literature searches, the SLANG-EM Workgroup identified four distinctive learning preferences of Generation Z learners: (1) individualized and self-paced learning, (2) engaging and visual learning environments, (3) immediate and actionable feedback, and (4) combined personal and academic support. Workgroup members evaluated these learning preferences using a novel conceptual framework informed by the theoretical principles underpinning SBE, recommending instructional strategies for Generation Z EM residency learners across multiple educational environments. Implications for educators: Instructional strategies were described for the didactic, simulation, and clinical learning environments. In the didactic environment, identified instructional strategies included meaningful asynchronous education, interactive small-group learning, and improved multimedia design. In the simulation environment, educational innovations particularly suitable for Generation Z learners included learner-centered debriefing, rapid-cycle deliberate practice, and virtual simulation. In the clinical environment, described instructional strategies involved setting learner-centered goals and delivering facilitative feedback in the context of an educational alliance. Overall, these instructional strategies were clustered around themes of student-centered education and the educator as facilitator, which align well with Generation Z learning preferences. These findings were synthesized and presented as an advanced workshop, "Delivering Effective Education to the Next Generation," at the 2023 SAEM Annual Meeting.

The Power of an Active Shooter Simulation: Changing Ethical Beliefs.

INTRODUCTION: During a hospital-based active shooter (AS) event, clinicians may be forced to choose between saving themselves or their patients. The Hartford Consensus survey of clinicians and the public demonstrated mixed feelings on the role of doctors and nurses in these situations. Our objective was to evaluate the effect of simulation on ethical dilemmas during a hospital-based AS simulation. The objective was to determine whether a hospital-based AS event simulation and debrief would impact the ethical beliefs of emergency physicians relating to personal duty and risk. METHODS: Forty-eight emergency physicians and physicians-in-training participated in this cohort study based in an urban academic hospital. Simulation scenarios presented ethical dilemmas for participants (eg, they decided between running a code or hiding from a shooter). Surveys based upon the Hartford Consensus were completed before and after the simulation. Questions focused on preparedness and ethical duties of physicians to their patients during an AS incident. We evaluated differences using a chi-squared test. RESULTS: Preparedness for an AS event significantly improved after the simulation (P = 0.0001). Pre-simulation, 56% of participants felt that doctors/nurses have a special duty like police to protect patients who cannot hide/run, and 20% reported that a provider should accept a very high/high level of personal risk to protect patients who cannot hide/run. This was similar to the findings of the Hartford Consensus. Interestingly, post-simulation, percentages decreased to 25% (P = 0.008) and 5% (P = 0.041), respectively. CONCLUSION: Simulation training influenced ethical beliefs relating to the duty of emergency physicians during a hospital-based AS incident. In addition to traditional learning objectives, ethics should be another important design consideration for planning future simulations in this domain.

Effects on membrane capacitance of steroids with antagonist properties at GABAA receptors.

We investigated the electrophysiological signature of neuroactive steroid interactions with the plasma membrane. We found that charged, sulfated neuroactive steroids, those that exhibit noncompetitive antagonism of GABA(A) receptors, altered capacitive charge movement in response to voltage pulses in cells lacking GABA receptors. Uncharged steroids, some of which are potent enhancers of GABA(A) receptor activity, produced no alteration in membrane capacitance. We hypothesized that the charge movements might result from physical translocation of the charged steroid through the transmembrane voltage, as has been observed previously with several hydrophobic anions. However, the charge movements and relaxation time constants of capacitive currents did not exhibit the Boltzmann-type voltage dependence predicted by a single barrier model. Further, a fluorescently tagged analog of a sulfated neurosteroid altered membrane capacitance similar to the parent compound but produced no voltage-dependent fluorescence change, a result inconsistent with a strong change in the polar environment of the fluorophore during depolarization. These findings suggest that negatively charged sulfated steroids alter the plasma membrane capacitance without physical movement of the molecule through the electric field.
