Introduction The novel coronavirus 2019 (COVID-19) pandemic in the United States (US) prompted widespread containment measures such as shelter-in-place (SIP) orders. The goal of our study was to determine whether there was a significant change in overall volume and proportion of emergency department (ED) encounters since SIP measures began. Methods This was a retrospective, observational, cross-sectional study using billing data from January 1, 2017–April 20, 2020. We received data from 141 EDs across 16 states, encompassing a convenience sample of 26,223,438 ED encounters. We used a generalized least squares regression approach to ascertain changes for overall ED encounters, hospital admissions, and New York University ED visit algorithm categories. Results ED encounters decreased significantly in the post-SIP period. Overall, there was a 39.6% decrease in ED encounters compared to expected volume in the pre-SIP period. Emergent encounters decreased by 35.8%, while non-emergent encounters decreased by 52.1%. Psychiatric encounters decreased by 30.2%. Encounters related to drugs and alcohol decreased the least, by 9.3% and 27.5%, respectively. Conclusion There was a significant overall reduction in ED utilization in the post-SIP period. There was a greater reduction in lower acuity encounters than higher acuity encounters. Of all subtypes of ED encounters, substance abuse- and alcohol-related encounters reduced the least, and injury-related encounters reduced the most.

Background Vaping-associated lung injury is a newly emerging disease process with the potential for serious health implications and high mortality, even despite the lack of underlying lung disease. We present a case of a young, otherwise healthy patient with tetrahydrocannabinol vaping-associated lung injury. Case presentation A 23-year-old Caucasian man with a past history of tetrahydrocannabinol vaping and benzodiazepine and methamphetamine abuse presented to the emergency department of our institution with a complaint of “feeling malnourished” over the past 5 days, along with associated fevers, cough, and vomiting. His past medical, surgical, family, and social histories were significant only for the recent use of marijuana vaping pens. Upon initial presentation, the patient appeared to be in significant respiratory distress. A computed tomographic scan of his chest demonstrated diffuse central predominant interstitial opacities, and he was admitted to the medical intensive care unit, where he was eventually intubated for hypoxic respiratory failure. No other cause of his respiratory failure was found, and it was ultimately believed that the patient had sustained a vaping-associated lung injury. Conclusion Tetrahydrocannabinol-containing vaping-associated lung injury is still poorly understood overall and is currently being investigated by the Centers for Disease Control and Prevention. In the meantime, physicians should consider vaping to be a public health emergency. We summarize the appropriate history, physical examination, appropriate workup, and therapies that physicians should be aware of in order to appropriately manage and treat patients presenting with suspected vaping-associated lung injury.

Objectives: Navigating the emergency department (ED) workflow in an efficient manner is an important skill every emergency physician or advanced provider must master. There is a paucity of research into ways to improve how efficiently an ED provider works amid these distractions. This study seeks to determine whether the addition of an hourly automated reminder for resident physicians to review their patient list improves throughput metrics.Methods: This a double-blinded randomized controlled trial in which resident physicians at a single community ED were randomly assigned to two groups: the intervention group, which received automated hourly notifications within the electronic medical record (EMR) to review their patient list for those whose workup is completed, and the control group, which received no notifications. We prospectively analyzed records for 25,255 encounters with 19,264 individual patients seen by 64 residents over the study period. Three-level mixed-effects regression models were used to examine whether notifications improved ED length of stay (ED-LOS), turnaround time to discharge (TAT-D), or turnaround time to admission (TAT-A).Results: There was no statistically significant difference in ED-LOS or TAT-D between groups, but the average TAT-A was 20.00 minutes longer in the intervention group compared to the control group (p < 0.001), after accounting for patient-and resident-specific effects. Secondary analysis demonstrated no statistically significant effect of residency specialty on the effect of notifications on ED-LOS, TAT-D, or TAT-A.Conclusions: Automated hourly notifications within the EMR reminding residents in the ED to review their patient list did not reduce the ED-LOS, TAT-D, or TAT-A. However, the TAT-A was 20.00 minutes longer in the intervention group compared to the control group. It is unclear whether this represents an unintended effect of the automated reminders or is simply a spurious correlation. E fficiency is an important skill all emergency medicine (EM) care providers (doctors and advanced practitioners) must master to successfully manage a busy emergency department (ED). EM care providers work in a fast-paced environment that is characterized by constant interruptions in their duties. 1 Care providers are constantly "task switching," wherein their attention, action, or both are constantly shifting from one task to another. 2,3 This phenomenon has become even more compounded by the advent of the From the
