Emergency department (ED) workers have an increased seroprevalence of SARS-CoV-2 antibodies. However, breakthrough infections in ED workers have led to a reduced workforce within a strained healthcare system. By measuring levels of IgG antibodies to the SARS-CoV-2 nucleocapsid and spike antigens in ED workers, we determined the incidence of infection and described the course of antibody levels. We also measured the antibody response to vaccination and examined factors associated with immunogenicity. ⋯ ED workers experienced a low incidence of SARS-CoV-2 infection and developed antibodies in response to vaccines and prior infection. Antibody levels decreased markedly with time since infection or vaccination.

The purpose of this study was to analyze the prevalence and significance of incidental findings on computed tomography pulmonary angiography (CTPA) studies and to assess the diagnostic yield of CTPA in identifying an alternate diagnosis to pulmonary embolism (PE) on PE negative exams. ⋯ CTPA may suggest an alternative diagnosis to pulmonary embolism in approximately 40% of the patients with a negative study. The probability of finding an alternate diagnosis (type 1 incidental) is higher in elderly patients and in patients referred from ICU and inpatient units.

Procalcitonin (PCT) is a biomarker with greater specificity for bacterial infection than other current laboratory markers. However, PCT can also be elevated in the setting of several noninfectious conditions. A recent case report describes a patient with elevated PCT in the context of acute methamphetamine intoxication, but without evidence of infection. ⋯ The area under the ROC curve was 0.65. Additionally, we describe 8 patients with confirmed absence of infection but with elevated PCT, 4 of whom had serum values >10 ng/ml. The results suggest that PCT has poor diagnostic utility for bacterial infection in patients with active methamphetamine use presenting to the ED.

It is thought vaccines allowed for emergency use significantly reduce hospitalizations and emergency room visits. It is a matter of curiosity how many of the patients who come to the emergency department (ED) are vaccinated. We aimed to examine the characteristics of ED patients needing hospitalizations related to moderate and severe COVID-19 by vaccination status. ⋯ In this study, age older than 65, unvaccinated, and comorbidities had significantly higher mortality. In multivariate regression analyses, age, vaccination status, comorbidities and the male gender were associated with mortality. Our study did not evaluate the vaccine efficacy but, a lower mortality rate was observed in those fully vaccinated with CoronaVac and Pfizer-BioNTech. Additionally, Alpha, Delta and other variants had the same mortality rates.

Case Reports Observational Study
Screening for health-related social needs in the emergency department: Adaptability and fidelity during the COVID-19 pandemic.
We sought to evaluate a screening and referral program for health-related social needs (HRSN) in our ED. Our goals were to (1) quantify successful screenings prior to and during the initial peak of the pandemic, and (2) describe the HRSNs identified. ⋯ We found that remote HRSN screening for ED patients during the COVID-19 pandemic resulted in similar proportions of successfully completed screenings compared to pre-pandemic efforts. This demonstrates the feasibility of utilizing alternative methods of screening and referral to community resources from the ED, which could facilitate this type of intervention in other EDs. During the pandemic HRSN increased, likely reflecting the economic impact of the pandemic.
