Relationship of the Built Environment on Nursing Communication Patterns in the Emergency Department: A Task Performance and Analysis Time Study.

INTRODUCTION: The physical layout of the emergency department affects the way in which patients and providers move within the space and can cause substantial changes in workflow and, therefore, affect communication patterns between providers. There is no 1 ED design that enables the best patient care, and quantitative studies looking at ED design are limited. The goal of this study was to examine how different ED designs, centralized and decentralized, are associated with communication patterns among health care professionals. METHODS: A task performance, direct observation time study was used. By developing a novel tablet-based digital mapping tool using a cloud-based mapping platform (ArcGIS), data on provider actions and interactions were collected and mapped to a precise location within the emergency department throughout an entire nursing shift. RESULTS: The difference in the duration of nurse-physician interactions between the 2 ED designs was statistically significant. Within the centralized design, nurse-physician interactions totaled 14 minutes and 38 seconds compared with 30 minutes and 11 seconds in the decentralized design (t = 2.31, P = 0.02). More conversations between nurses and physicians occurred inside the patient's room in the decentralized design. DISCUSSION: Our findings suggest that the ED design affects communication patterns among health care providers and that the design has the potential to affect the quality of patient care.

Is there an oxidative cost of acute stress? Characterization, implication of glucocorticoids and modulation by prior stress experience.

Acute rises in glucocorticoid hormones allow individuals to adaptively respond to environmental challenges but may also have negative consequences, including oxidative stress. While the effects of chronic glucocorticoid exposure on oxidative stress have been well characterized, those of acute stress or glucocorticoid exposure have mostly been overlooked. We examined the relationship between acute stress exposure, glucocorticoids and oxidative stress in Japanese quail (Coturnix japonica). We (i) characterized the pattern of oxidative stress during an acute stressor in two phenotypically distinct breeds; (ii) determined whether corticosterone ingestion, in the absence of acute stress, increased oxidative stress, which we call glucocorticoid-induced oxidative stress (GiOS); and (iii) explored how prior experience to stressful events affected GiOS. Both breeds exhibited an increase in oxidative stress in response to an acute stressor. Importantly, in the absence of acute stress, ingesting corticosterone caused an acute rise in plasma corticosterone and oxidative stress. Lastly, birds exposed to no previous acute stress or numerous stressful events had high levels of GiOS in response to acute stress, while birds with moderate prior exposure did not. Together, these findings suggest that an acute stress response results in GiOS, but prior experience to stressors may modulate that oxidative cost.

Characteristics and Motivating Factors of Attendees of a Regional Student-Run Wilderness Medicine Conference.

Despite recent growth, opportunities for preclinical medical students to engage with the field of wilderness medicine remain geographically, financially, and logistically limited. Attendees of the 2018 Mid-Atlantic Student Wilderness Medicine Conference were invited to complete a post hoc web-based survey after the event. Results of the survey were analyzed to determine the demographic characteristics and motivating factors for attendance, as well as perceived conference performance and future behavioral intention of survey respondents. The majority of attendees were preclinical level medical students, 37% of whom were affiliated with their institutions' wilderness medicine interest group and 40% of whom were affiliated with an emergency medicine interest group. Intrinsically motivating factors such as personal interest and opportunities for educational enrichment were significantly more important in determining conference attendance than extrinsically motivating factors such as cost and networking opportunities. Data from this conference support many encouraging trends and suggest that regional conferences may represent a practical way to increase access to wilderness medicine in the preclinical medical student population and thereby influence career decision.
