We have quantum chemically investigated the nature and stability of C-C and Si-Si bonds in RA-AR (A = C, Si; R = H, Me, MePh, MePh, Ph, -Bu) using density functional theory (DFT). Systematic increase of steric bulk of the substituents R has opposite effects on C-C and Si-Si bonds: the former becomes weaker whereas the latter becomes stronger. Only upon going further, from R = Ph to the bulkiest R = -Bu, the RSi-SiR bond begins to weaken.

The American College of Emergency Physicians (ACEP) Emergency Medicine Quality Network (E-QUAL) Opioid Initiative was launched in 2018 to advance the dissemination of evidence-based resources to promote the care of emergency department (ED) patients with opioid use disorder. This virtual platform-based national learning collaborative includes a low-burden, structured quality improvement project, data benchmarking, tailored educational content, and resources designed to support a nationwide network of EDs with limited administrative and research infrastructure. As a part of this collaboration, we convened a group of experts to identify and design a set of measures to improve opioid prescribing practices to provide safe analgesia while reducing opioid-related harms.

Background: Public reporting of the Centers for Medicare & Medicaid (CMS) SEP-1 sepsis quality measure is often too late and without the data granularity to inform real-time quality improvement (QI). In response, the American College of Emergency Physicians (ACEP) Emergency Quality Network (E-QUAL) Sepsis Initiative sought to support QI efforts through benchmarking of preliminary draft SEP-1 scores for emergency department (ED) patients. This study sought to determine the anticipatory value of these preliminary SEP-1 benchmarking scores and publicly reported performance.

We have quantum chemically investigated how methyl substituents affect the stability of alkyl radicals Me H C⋅ and the corresponding Me H C-X bonds (X = H, CH , OH; m = 0 - 3) using density functional theory at M06-2X/TZ2P. The state-of-the-art in physical organic chemistry is that alkyl radicals are stabilized upon an increase in their degree of substitution from methyl View Article and Find Full Text PDF

Objectives: Despite increasing ED visits, evidence suggests overall hospitalization rates have decreased; however, it is unknown what clinical conditions account for these changes. We aim to describe condition-specific trends and hospital-level variation in hospitalization rates after ED visits from 2006 to 2014.

Methods: Retrospective observational study of adult ED visits to U.

Introduction: Voters facing illness or disability are disproportionately under-represented in terms of voter turnout. Earlier research has indicated that enfranchisement of these populations may reinforce the implementation of policies improving health outcomes and equity. Due to the confluence of the coronavirus 2019 (COVID-19) pandemic and the 2020 election, we aimed to assess emergency absentee voting processes, which allow voters hospitalized after regular absentee deadlines to still obtain an absentee ballot, and election changes due to COVID-19 in all 50 states.

Unlabelled: Appropriate sanitation is crucial to alleviate pressures on environmental and human health hazards. Conventional (sewered) sanitation systems are often not viable in rapidly developing urban areas, where over 70% of the world population is expected to live in 2050. Freshwater is polluted and valuable resources such as nutrients and organics are lost.

We have quantum chemically analyzed element-element bonds of archetypal H X-YH molecules (X, Y=C, N, O, F, Si, P, S, Cl, Br, I), using density functional theory. One purpose is to obtain a set of consistent homolytic bond dissociation energies (BDE) for establishing accurate trends across the periodic table. The main objective is to elucidate the underlying physical factors behind these chemical bonding trends.

Background: Acute pain from a vaso-occlusive crisis (VOC) is a leading reason patients with sickle cell disease (SCD) visit the emergency department (ED). Prior studies suggest that women and men receive disparate ED treatment for acute pain in EDs. We aim to determine sex differences in analgesic use among patients with SCD presenting to the ED.

Background: The Merit-based Incentive Payment System (MIPS) is the largest national pay-for-performance program and the first to afford emergency clinicians unique financial incentives for quality measurement and improvement. With little known regarding its impact on emergency clinicians, we sought to describe participation in the MIPS and examine differences in performance scores and payment adjustments based on reporting affiliation and reporting strategy.

Methods: We performed a cross-sectional analysis using the Centers for Medicare & Medicaid Services 2018 Quality Payment Program (QPP) Experience Report data set.

Introduction: Nontechnical skills (NTS) in medicine are the "cognitive, social, and personal resource skills that complement technical skills contributing to safe and efficient care." We aimed to (1) evaluate the validity and reliability of a 12-element United Kingdom emergency medicine (EM) NTS assessment tool in the context of United States (US) EM practice and (2) identify behaviors unique to US clinical practice.

Methods: This was a mixed methods study conducted in 2 phases, following Kane's validity framework.

Objective: Assess whether clinical data were present in emergency department (ED) provider notes at time of order entry for cervical spine (c-spine) imaging that could be used to augment or pre-populate clinical decision support (CDS) attributes.

Methods: This Institutional Review Board-approved retrospective study, performed in a quaternary hospital, included all encounters for adult ED patients seen April 1, 2013-September 30, 2014 for a chief complaint of trauma who received c-spine computed tomography (CT) or x-ray. We assessed proportion of ED encounters with at least 1 c-spine-specific CDS rule attribute in clinical notes available at the time of imaging order and agreement between attributes in clinical notes and data entered into CDS.

Importance: Wrong-patient order entry (WPOE) errors have a high potential for harm; these errors are particularly frequent wherever workflows are complex and multitasking and interruptions are common, such as in the emergency department (ED). Previous research shows that interruptive solutions, such as electronic patient verification forms or alerts, can reduce these types of errors but may be time-consuming and cause alert fatigue.

Objective: To evaluate whether the use of noninterruptive display of patient photographs in the banner of the electronic health record (EHR) is associated with a decreased rate of WPOE errors.
