The Ed Is Inherently Interleaved: The Learning Theory Case For Hybrid Resident Conference Curriculum Design In Emergency Medicine: Block For Onboarding And For Specialized Topics With Predominant Interleaving For Intermediate And Advanced Residents, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background

Emergency medicine (EM) training occurs within a clinical environment characterized by rapid context switching, diagnostic uncertainty, and frequent transitions between unrelated clinical problems. Didactic curricula that rely only on block-based topic organization may not fully reflect the cognitive demands of real emergency department practice.

Objective

To propose a developmentally adaptive hybrid model of EM curricular design that integrates early block learning during the onboarding phase of new residents, progressing to a general approach of interleaved learning. Specialized topics,  can be introduced using block learning at any time during the residency years.

Methods / Conceptual Approach

This conceptual educational model …

Reframing Emergency Medicine (And Healthcare) Wellness Measures: The Case For Adding Measures Of Physiological Sustainability, Exercise, Restoration, And Meaning, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background

Physician wellness measurement in Emergency Medicine (EM) in particular and in healthcare in general has largely focused on identifying distress states such as emotional exhaustion and depersonalization. Instruments such as the Maslach Burnout Inventory and related derivative surveys have been well-validated and  have played a central role in identifying the scope of burnout across healthcare systems.

Conceptual Framing

While current measures of distress are essential, they may not fully characterize the spectrum of clinician health. In many fields outside healthcare—including occupational health, resilience research, and positive psychology—assessment of well-being includes behaviors and experiences associated with sustained health, such as …

Reframing The Ed–Hospitalist Admission As A Clinical Handoff: The Ed To Hospital Admission As A Cross-System Handoff In A Complex Adaptive Clinical Environment. The Case For Systems Approaches To Enhance Safe And Effective Transitions Across A True System Interface, James Espinosa, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Background

Transitions from the Emergency Department (ED) to hospital medicine represent a high-stakes clinical handoff across systems. While often experienced as challenging, these interactions are better understood as occurring between services operating under different cognitive loads, operational priorities, and time horizons. Reframing the ED–hospitalist admission as a structured handoff aligns this process with broader patient safety efforts.

Objective

To characterize the ED–hospitalist admission as a cross-system clinical handoff and to identify practical strategies that enhance safety, clarity, and alignment during this transition.

Methods

Conceptual analysis informed by clinical experience, systems theory, and teaching observations. Key domains of potential misalignment were …

Shopping Cart–Related Injuries In Children: Brief Clinical Review And Public Health Implications, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Shopping cart–related injuries represent a common yet underrecognized mechanism of pediatric trauma. National estimates suggest approximately 24,000 children annually are treated in U.S. emergency departments for shopping cart–related injuries, with falls accounting for the majority of cases. Younger children, particularly those under 5 years of age, are disproportionately affected, and head and facial injuries predominate.

Objective:

To provide a concise clinical and public health review of shopping cart–related pediatric injuries, with emphasis on epidemiology, injury patterns, and opportunities for prevention within emergency department practice.

Methods

Narrative review of national injury surveillance data, prior epidemiologic studies, and consumer safety guidance addressing …

Hydration During Emergency Medicine Shifts: An Overlooked Component Of Cognitive Performance, Well-Being, And Systems Design To Fail To Plan For Shift Hydration Is To Plan To Fail With Shift Hydration, James Espinosa, Alan Lucerna, Swet Patel, Robin Lahr, Sergey Medlenov, Adam Kandil, Frank Wheeler, Wayne Tamaska, James Lee, Neel Parikh, Henry Schuitema

Rowan-Virtua Research Day

Emergency Medicine (EM) clinicians work prolonged, cognitively demanding shifts in environments characterized by unpredictability, interruptions, and high decision density. While fatigue, burnout, and circadian disruption have been widely studied, hydration during active clinical shifts has received little focused attention. Evidence from cognitive, military, and sports physiology literature demonstrates that even mild dehydration can impair attention, working memory, mood, and reaction time. Despite these findings, hydration in Emergency Medicine is typically treated as an individual behavior rather than a systems-level design consideration. This review synthesizes relevant physiologic and performance literature, identifies cultural and structural barriers to hydration during EM shifts, and …

Learning From Our Dental Colleagues: A Brief Review Of Counter-Stimulation To Reduce Procedural Pain In Emergency Medicine Mechanisms, Existing Evidence, And A Pragmatic Research Agenda, James Espinosa, Neal Appelstein, Alan Lucerna

Rowan-Virtua Research Day

Counter-stimulation techniques such as tapping, pressure, vibration, and tissue shaking are commonly observed in dental practice during administration of local anesthetic nerve blocks. Although not systematically described in the Emergency Medicine literature, individual clinicians may employ tactile counter-stimulation techniques during needle-based procedures. The practice remains under-theorized and under-studied within the Emergency Medicine literature. This brief review synthesizes mechanistic neurobiology—including segmental gate control theory (Melzack & Wall, 1965), descending inhibitory modulation, and attentional salience models—with evidence from dental and needle-procedure research. We propose a practical taxonomy of counter-stimulation techniques applicable to Emergency Medicine and identify gaps in the current literature. Finally, …

The Complex World Of Emergency Department Medication Dosing: Weight Scalars, Dose And Area Under The Curve (Auc) In Medication Dosing--Areas For Future Research, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Weight-based dosing is foundational to emergency medicine practice. With modern ED beds capable of automatic patient weighing, inaccuracies in estimated weight have largely diminished. However, medication misalignment persists, particularly in patients at extremes of body weight and in high-stakes clinical contexts such as rapid sequence intubation (RSI), antimicrobial therapy, and anticoagulation. Emerging pharmacokinetic literature emphasizes total drug exposure—represented by the area under the concentration–time curve (AUC)—as a stronger correlate of efficacy and toxicity than single-point serum levels. This review explores where weight precision most likely matters in the ED, examines weight scalars, and reframes dosing decisions through an exposure-centered paradigm. …

Towards More Effective And Efficient Ite And Board Preparation In Emergency Medicine: A Conceptual Framework Using Personality Preferences (Mbti) To Inform Study And Test-Taking Behaviors, James Espinosa, Robin Lahr, James Lee, Alan Lucerna

Rowan-Virtua Research Day

Background: Preparation for high-stakes examinations in Emergency Medicine (EM) relies heavily on question-bank practice, rapid decision-making, and targeted review. Despite standardized board-preparation resources, trainees demonstrate substantial variability in study behaviors and perceived efficiency. The Myers-Briggs Type Indicator (MBTI), widely used in medical education for communication and self-reflection, may offer a framework for understanding differences in study and test-taking behaviors, though it is not designed as a predictive psychometric tool.

Objective: To review existing literature relating MBTI preferences to learning behaviors and academic performance, and to propose a conceptual framework linking personality preferences to board-style test-taking patterns in EM trainees.

Methods: …

Listening To The System: Reframing Emergency Department Noise: The Case For Noise As A Real-Time Operational Signal In A Complex Adaptive System (Cas), James Espinosa, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Emergency Department (ED) noise has historically been framed as an occupational and environmental hazard requiring mitigation. And this is still true—but not complete. Early work focused on exposure reduction and spike identification. Subsequent mapping studies demonstrated spatial and temporal differentiation in ED acoustic load. We propose an expanded conceptual model: acoustic variability may function not only as a hazard, but also as a real-time signal of operational turbulence within the ED as a complex adaptive system (CAS). Drawing on human factors, alarm fatigue, resilience engineering, and complexity science, we synthesize existing literature and institutional experience to identify a critical gap—noise …

When The Clock Stands Still: Clock Time Vs. Experienced Time In The Emergency Department Brief Review: Neurobiology Of Time Perceptiontemporal Distortion As A Marker Of Cognitive Load And Operational Turbulence, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: Emergency clinicians frequently report that time during ED shifts can feel unusually slow or unusually fast. This shared observation has rarely been examined formally in emergency medicine. Altered time perception has also been described in high demand professions such as aviation, sports, military operations, and emergency response. Individuals often report time dilation during critical events and time compression during highly coordinated performance. These findings suggest that temporal perception reflects underlying neurocognitive responses to environmental demands. Emergency departments share many characteristics with these environments, including rapid decision making, task switching, and intermittent high stakes events.

Objective:  Brief narrative review concerning …

From Lists To Landscapes And Locations: Spatial Memory And Schema Formation (Memory Palace Adaptation) As A Neurobiologically Informed Strategy For Teaching Environmental And Toxicology Emergencies Ite And Board Review In Emergency Medicine Residency, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background:

Most emergency medicine board domains inherit spatial scaffolding from foundational anatomy education (e.g., neuroanatomy, gastrointestinal tract, cardiopulmonary structures). Environmental emergencies lack an inherent anatomic anchor and are frequently taught as disconnected lists, increasing cognitive load and impairing schema formation. Similarly, toxicology crosses age, and specialty without an inherent anatomic structural anchor.

Objective:

To describe a scene-based, learner-generated landscape model designed to reintroduce spatial structure into environmental emergency education and to situate the model within contemporary neurobiology and learning science.

Educational Innovation:

Residents construct a large-format landscape diagram (sun–water–mountain schema) during live instruction. Environmental conditions are spatially anchored in ecologically …

The Ones That Got Away:Shared Misses, Shared Mastery — A Proposal For Leveraging Spaced Retrieval, Variable Reinforcement, And Collective Learning In Emergency Medicine Residency, James Espinosa D, Robin Lahr, James Lee, Swet M. Patel, Alan Lucerna

Rowan-Virtua Research Day

Background

Residents frequently engage in individual question-bank study for board preparation; however, missed questions are typically processed in isolation. Educational psychology demonstrates that spaced retrieval and variable reinforcement enhance durable learning. Psychological safety further supports collective sense-making in professional education . The addition of a periodic, structured, collective shared-review process model may leverage these principles within residency training.

Objective

To propose a resident-driven educational initiative that transforms individually missed board-style questions into a shared, psychologically safe learning stream that promotes durable knowledge retention and community-based mastery.  The movement of this stream could be a chief resident responsibility, or could be …
