Adherence to institutional stroke alert criteria in an academic adult emergency department population.

Background: Timely recognition of acute ischemic stroke (AIS) is essential to identify patients who may be eligible for acute intervention. Protocols to streamline systems-based care, such as "stroke alerts" in the emergency department (ED) can safely reduce time-to-care while enhancing safety. However, clinician adherence to stroke alert criteria is poorly described.

Optimal Cutoff Values and Utility of High-Sensitivity Troponin T and NT-proBNP for the Risk Stratification of Patients with Acute Pulmonary Embolism.

Background: Guidelines recommend using high-sensitivity troponin T (hsTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) to risk stratify hemodynamically stable patients with acute pulmonary embolism (PE). However, there are no evidence-based cutoff values defined for this clinical application.

Methods: We performed a single-center, retrospective cohort study of patients with imaging-confirmed PE and hsTnT and/or NT-proBNP (ElecsysTM, Roche) measured 12 h before or 24 h after PE Response Team (PERT) activation.

Development and results of a novel emergency medicine residency research immersion program.

Creating a sustainable residency research program is necessary to develop a sustainable research pipeline, as highlighted by the recent Society for Academic Emergency Medicine 2024 Consensus Conference. We sought to describe the implementation of a novel, immersive research program for first-year emergency medicine residents. We describe the curriculum development, rationale, implementation process, and lessons learned from the implementation of a year-long research curriculum for first-year residents.

Emergency department diagnosis and management of acute pulmonary embolism.

Despite advances in clinical decision support, the diagnosis, prognostic risk stratification, treatment and disposition of emergency department patients with pulmonary embolism remain challenging. The use of diagnostic risk stratification tools and D-dimer can decrease unnecessary exposure to radiation and intravenous contrast; however, D-dimer is elevated in many conditions including normal pregnancy, so imaging is often indicated. Once diagnosed, prognostic risk stratification tools can inform treatment decisions across the risk spectrum, including identifying low-risk patients with pulmonary embolism who can safely be treated at home.

Derivation and external validation of a portable method to identify patients with pulmonary embolism from radiology reports: The READ-PE algorithm.

Background: Identification of pulmonary embolism (PE) across a cohort currently requires burdensome manual review. Previous approaches to automate capture of PE diagnosis have either been too complex for widespread use or have lacked external validation. We sought to develop and validate the Regular Expression Aided Determination of PE (READ-PE) algorithm, which uses a portable text-matching approach to identify PE in reports from computed tomography with angiography (CTA).

Choroidal Nevi in Children: Size, Growth, and Topographic Distribution.

Purpose: To explore size, growth, and topographic distribution of choroidal nevi in children to gain insights into choroidal nevogenesis.

Design: Retrospective consecutive case series using pediatric clinic - and population-study data, comparing to adult data.

Methods: Clinical data from Cole Eye Institute (CEI) database (December 2005-January 2023) was derived from a retrospective consecutive case series of 20 children (< 20 years) with choroidal nevi.

Characteristics and Health Care Utilization of Patients With Housing Insecurity in the ED.

Importance: Unstable housing and homelessness can exacerbate adverse health outcomes leading to increased risk of chronic disease, injury, and disability. However, emergency departments (EDs) have no universal method to identify those at risk of or currently experiencing homelessness.

Objective: To describe the extent of housing insecurity among patients who seek care in an urban ED, including chief concerns, demographics, and patterns of health care utilization.

Characteristics and outcomes of prehospital and emergency department surgical airways.

Objectives: The surgical airway is a high acuity, low occurrence procedure. Data on the complications and outcomes of surgical airways are limited. Our primary objective was to describe immediate complications, late complications, and clinical outcomes of patients who underwent a surgical airway procedure in the prehospital or emergency department (ED) setting.

Surveillance for Metastasis in High-Risk Uveal Melanoma Patients: Standard versus Enhanced Protocols.

Purpose: to evaluate the effectiveness of enhanced surveillance protocols (EP) utilizing high frequency (HF) or enhanced modality (EM) compared to the standard protocol (SP) in detecting metastasis and determining their impact on overall survival (OS) in high-risk uveal melanoma (UM) patients.

Methods: A total of 87 consecutive patients with Class 2 (high risk) primary UM were enrolled, with negative baseline systemic staging. The patients underwent systemic surveillance with either SP (hepatic ultrasonography [US] every 6 months) or EP (either HF [US every 3 months] or EM [incorporation hepatic computed tomography/magnetic resonance imaging]) following informed discussion.

Limitations in the use of automated mental status detection for clinical decision support.

Background: Clinical decision support (CDS) tools improve adherence to evidence-based practices but are dependent upon data quality in the electronic health record (EHR). Mental status is an integral component of many risk stratification scores, but it is not known whether EHR-measures of altered mental status are reliable. The Glasgow Coma Scale (GCS) is a measure of altered mentation that is widely adopted and entered in the EHR in structured format.

Using intervention mapping to design and implement a multicomponent intervention to improve antibiotic and NSAID prescribing.

Successfully changing prescribing behavior to reduce inappropriate antibiotic and nonsteroidal anti-inflammatory drug (NSAID) prescriptions often requires combining components into a multicomponent intervention. However, multicomponent interventions often fail because of development and implementation complexity. To increase the likelihood of successfully changing prescribing behavior, we applied a systematic process to design and implement a multicomponent intervention.

Cefepime vs Piperacillin-Tazobactam in Adults Hospitalized With Acute Infection: The ACORN Randomized Clinical Trial.

Importance: Cefepime and piperacillin-tazobactam are commonly administered to hospitalized adults for empirical treatment of infection. Although piperacillin-tazobactam has been hypothesized to cause acute kidney injury and cefepime has been hypothesized to cause neurological dysfunction, their comparative safety has not been evaluated in a randomized clinical trial.

Objective: To determine whether the choice between cefepime and piperacillin-tazobactam affects the risks of acute kidney injury or neurological dysfunction.

Peripheral Hemorrhagic Chorioretinopathy: Differentiating Features from Choroidal Melanoma.

Introduction: Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is one of the leading mimickers of choroidal melanoma because of overlapping features with choroidal melanoma that make the distinction between these two entities difficult.

Methods: To identify nonoverlapping diagnostic features between PEHCR and choroidal melanoma, a retrospective study of 80 patients (80 eyes); 40 patients (40 eyes) with PEHCR; and 40 patients (40 eyes) with choroidal melanoma was conducted. Ophthalmoscopic and imaging features of PEHCR and choroidal melanoma were compared.

Clustering of uveal melanoma: County wide analysis within Ohio.

Purpose: To determine if a greater than expected number of cases (clustering) of uveal melanoma occurred within Ohio for any specific region or time period as compared to others.

Design: Analysis of population database.

Methods: Ohio Cancer Incidence Surveillance System (OCISS) database (2000-2019) was accessed for the diagnosis of uveal melanoma using the International Classification of Disease for Oncology codes: C69.

Randomized controlled trial of urinE chemiStry guided aCute heArt faiLure treATmEnt (ESCALATE): Rationale and design.

Diuresis to achieve decongestion is a central aim of therapy in patients hospitalized for acute decompensated heart failure (ADHF). While multiple clinical trials have investigated initial diuretic strategies for a designated period of time, there is a paucity of evidence to guide diuretic titration strategies continued until decongestion is achieved. The use of urine chemistries (urine sodium and creatinine) in a natriuretic response prediction equation accurately estimates natriuresis in response to diuretic dosing, but a randomized clinical trial is needed to compare a urine chemistry-guided diuresis strategy with a strategy of usual care.

Complex Patient Perspectives on Evolving Diverticulitis Treatment Patient Perspectives on Diverticulitis.

Background: Despite evidence that antibiotics may not be necessary to treat acute uncomplicated diverticulitis, they remain the mainstay of treatment in the United States. A randomized controlled trial evaluating antibiotic effectiveness could accelerate implementation of an antibiotic-free treatment strategy, but patients may be unwilling to participate.

Objective: This study aims to assess patients' attitudes regarding participation in a randomized trial of antibiotics versus placebo for acute diverticulitis, including willingness to participate.

Uveal melanoma in African Americans: Diagnostic challenges.

Uveal melanoma (UM) is uncommon in African Americans. Owing to its rarity, UM may not be suspected in African Americans leading to delayed diagnosis. In addition, socioeconomic factors may also play a role in delayed diagnosis.

Iris melanoma: Prognostication for metastasis.

Uveal melanoma prognostication studies have mainly included posterior uveal melanomas located in the ciliary body and choroid, often excluding iris melanoma. In this study, we report prognostic status and survival outcomes in a series of 35 patients with biopsy-proven iris melanoma. Fluorescence in situ hybridization was performed in 10 (29%) cases and 2 (5%) underwent multiplex ligation-dependent probe amplification.

Trends in paediatric firearm-related encounters during the COVID-19 pandemic by age group, race/ethnicity and schooling mode in Tennessee.

Background: Increases in paediatric firearm-related injuries during the COVID-19 pandemic may be due to changes in where children and adolescents spent their time. This study examines changes in the frequency of paediatric firearm-related encounters as a function of schooling mode overall and by race/ethnicity and age group at a large trauma centre through 2021.

Methods: We use data from a large paediatric and adult trauma centre in Tennessee from January 2018 to December 2021 (N=211 encounters) and geographically linked schooling mode data.
