The objective was to derive and validate a novel queuing theory-based model that predicts the effect of various patient crowding scenarios on patient left without being seen (LWBS) rates. ⋯ This novel queuing theory-based model predicts the effect of patient arrivals, treatment time, and ED boarding on the rate of patients who LWBS at one institution. More studies are needed to validate this model across other institutions.

Emergency physicians (EPs) frequently evaluate patients at risk for diseases that cause optic disc swelling, and they may encounter conditions that make traditional fundoscopy difficult or impossible. The objective was to assess whether EP-performed point-of-care (POC) ultrasound (US) could accurately assess swelling of the optic disc. ⋯ These data suggest that EP-performed POC US can detect clinically apparent optic disc swelling. Because sonography can be performed readily at the bedside, even in cases where fundoscopy is difficult or impossible, this technique may prove to be a valuable tool for the assessment of optic disc swelling in the emergency department (ED).

Observational Study
Diagnostic Accuracy of Fingerstick β-Hydroxybutyrate for Ketonuria in Pregnant Women With Nausea and Vomiting.
The aim of this study was to determine whether a rapid, fingerstick β-hydroxybutyrate (β-OHB) test predicts ketonuria in pregnant women with nausea and vomiting. ⋯ Fingerstick β-OHB is a rapid and reliable diagnostic tool that correlates well with ketonuria and identifies ketonemia in pregnant women with nausea and vomiting. Fingerstick β-OHB testing has the potential to increase triage efficiency, shorten length-of-stay times, and positively affect patient outcomes in an ED setting.

The authors sought to describe the demographic and clinical characteristics of interhospital transfers from U.S. emergency departments (EDs) along with the primary reasons for transfers. ⋯ Transfer of ED patients was relatively rare, but was more common among specific, potentially high-risk populations. Diagnostic testing, including advanced imaging, was common prior to transfer. A majority of transfers were for reasons indicating limited resources or expertise at the referring facility.
