Review
Overcoming Stagnant Flow - A Scoping Review of Vertical Movement in the Emergency Department.
Improving emergency department (ED) patient flow has plagued many hospitals worldwide. "Vertical" flow improves throughput by maximizing use of chairs and waiting areas instead of beds. This process, however, is inconsistently described in the literature. The objective of this study was to collate existing evidence of successful vertical care programs. ⋯ The findings of this scoping review provide the first summative report of existing literature on vertical flow processes within the ED setting. Despite different measurable outcomes and varied processes, most articles support the use of vertical flow to improve throughput.

Vital signs are a critical component of the prehospital assessment. Prior work has suggested that vital signs may vary in their distribution by age. These differences in vital signs may have implications on in-hospital outcomes or be utilized within prediction models. We sought to (1) identify empirically derived (unadjusted) cut points for vital signs for adult patients encountered by emergency medical services (EMS), (2) evaluate differences in age-adjusted cutoffs for vital signs in this population, and (3) evaluate unadjusted and age-adjusted vital signs measures with in-hospital outcomes. ⋯ We describe cut points for vital signs for adults in the out-of-hospital setting that are associated with both mortality and hospitalization. While we found age-based differences in vital signs cutoffs, this adjustment only slightly improved model performance for in-hospital outcomes.

Vital signs are frequently used in pediatric prehospital assessments and guide protocol utilization. Common pediatric vital sign classification criteria identify >80% of children in the prehospital setting as having abnormal vital signs, though few receive lifesaving interventions (LSIs). We sought to identify data-driven thresholds for abnormal vital signs by evaluating their association with prehospital LSIs. ⋯ Cut points for pediatric vital signs were associated with LSIs. Specific age-adjusted ranges can identify children at higher and lower risk for receipt of LSI. These ranges may be combined with other objective measures to improve the assessment of children in the prehospital setting, assist in optimizing protocol utilization, improve transport decision making, and guide destination selection.

The diagnostic performance of the high-sensitivity troponin T (hs-cTnT) 0/2-h algorithm is unclear among U.S. emergency department (ED) patients with acute chest pain. ⋯ The hs-cTnT 0/2-h algorithm ruled out most patients. With NPV of <99% for 30-day CDMI, the hs-cTnT 0/2-h algorithm, many emergency physicians may not consider it safe to use for U.S. ED patients. When combined with a low-risk HEAR score, NPV was >99% for 30-day CDMI at the cost of reduced efficacy.

Observational Study
Dexmedetomidine in the emergency department: a prospective observational cohort study.
Dexmedetomidine (DEX) is a centrally acting sympatholytic sedative. Abundant evidence from the intensive care unit and other settings demonstrates that the use of DEX is associated with improved sedation-related outcomes. There is a paucity of data on the use and efficacy of DEX in the emergency department (ED). ⋯ DEX is used in the ED for diverse indications. Additional data from larger cohorts and comparative studies are required to determine the precise incidence of clinically significant HAE associated with DEX use in the ED. ED clinicians have a positive perception of the effectiveness of DEX.
