Study Objective: To characterize the emergency medicine resident physician workforce and the residency programs training them.

Methods: We identified emergency medicine residents in the 2020 American Medical Association (AMA) Physician Masterfile, analyzed demographic information, mapped both county-level population-adjusted and hospital referral region densities, and compared 2020 versus 2008 resident physician densities. We also analyzed all Accreditation Council for Graduate Medical Education (ACGME)-accredited emergency medicine residency programs from 2013 to 2020, mapped state-level population-adjusted densities, and identified temporal trends in program location and state-level program densities.

Study Objective: To examine the diagnostic pattern, level of severity of illness or injuries, and mortality among children for whom a physician-staffed helicopter emergency medical service (HEMS) was dispatched.

Methods: Population-based cohort study including patients aged less than 16 years treated by the Danish national HEMS from October 1, 2014, to September 30, 2018. Diagnoses were retrieved from inhospital medical records, and the severity of illness or injuries was assessed by a severity score on scene, administration of advanced out-of-hospital care, need for intensive care in a hospital, and mortality.

Study Objective: During the delta surge of the COVID-19 pandemic in 2021, we sought to identify characteristics and beliefs associated with COVID-19 vaccination acceptance in parents of pediatric emergency department (ED) patients.

Methods: We conducted a cross-sectional survey-based study of the parents of children aged 3 to 16 years presenting to 1 of 9 pediatric EDs from June to August 2021 to assess the parental acceptance of COVID-19 vaccines. Using multiple variable regression, we ascertained which factors were associated with parental and pediatric COVID-19 vaccination acceptance. Read More

Study Objective: Large doses of intramuscular (IM) naloxone are commonly used in out-of-hospital settings to reverse opioid toxicity; however, they are used less commonly in hospitals because of concerns about opioid withdrawal, particularly agitation. We aimed to determine the frequency of severe agitation following a single 1.6 mg IM naloxone dose. Read More

Study Objective: Emergency department (ED) evaluations for syncope are common, representing 1.3 million annual US visits and $2 billion in related hospitalizations. Despite evidence supporting risk stratification and outpatient management, variation in syncope hospitalization rates persist. Read More

Study Objective: To examine sex differences in oral anticoagulation management and outcomes among patients with incident nonvalvular atrial fibrillation presenting to the emergency department (ED).

Methods: We identified patients older than 20 years presenting to the ED with incident nonvalvular atrial fibrillation between April 1, 2012, and March 30, 2019, using linked administrative databases in Alberta, Canada. We assessed the use of and adherence to oral anticoagulants at 1 year using the proportion of days covered for direct oral anticoagulants and time in therapeutic range for warfarin. Read More

Study Objective: To evaluate aerosol dispersion and exposure risk during oxygenation therapy among health care personnel.

Methods: This study compared the aerosol dispersion effect produced through continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP), BiPAP with face coverings, a high-flow nasal cannula (HFNC) with face coverings, nasal cannula oxygenation (NCO) at 15 L/min with face coverings, nonrebreather mask (NRM), and ventilator-assisted preoxygenation (VAPOX) during oxygenation therapy at a minute ventilation of 10 L/min and 20 L/min. The length and width of aerosol dispersion were recorded, and aerosol concentrations were then detected at a mannequin's head, trunk, and feet. Read More
