ObjectiveTo measure the association of race, ethnicity, comorbidities, and insurance status with need for hospitalization of symptomatic Emergency Department (ED) patients with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection.MethodsThis study is a retrospective case-series of symptomatic patients presenting to a single ED with laboratory-confirmed SARS-CoV-2 infection from March 12-August 9, 2020. We collected patient-level information regarding demographics, public insurance status (Medicare or Medicaid), comorbidities, level of care, and mortality using a structured chart review. We compared demographics and comorbidities of patients who were (1) able to convalesce at home, (2) required admission to general medical service, (3) required admission to intensive care unit (ICU), or (4) died within 30 days of the index visit. Multivariable logistic regression analyses were performed to report adjusted odds ratios (aOR) and the associated 95% confidence intervals (95% CI) with hospital admission versus ED discharge home.ResultsIn total, 993 patients who presented to the ED with symptoms were included in the analysis with 370 (37.3%) patients requiring hospital admission and 70 (7.1%) patients requiring ICU care. Patients requiring admission were more likely to be Black or African American, to be Hispanic or Latino, or to have public insurance (either Medicaid or Medicare.) On multivariable logistic regression analysis comparing which patients required hospital admission, African-American race (aOR 1.4, 95% CI 0.7-2.8) and Hispanic ethnicity (aOR 1.1, 95% CI 0.5-2.0) were not associated with need for admission but, public insurance (Medicaid: aOR 3.4, 95% CI 2.2-5.4; Medicare: aOR 2.6, 95% CI 1.2-5.3; Medicaid and Medicare: aOR 3.6 95% CI 2.1-6.2) and the presence of hypertension (aOR 1.8, 95% CI 1.2-2.7), diabetes (aOR 1.6, 95% CI 1.1-2.5), obesity (aOR 1.7, 95% CI 1.1-2.5), heart failure (aOR 3.9, 95% CI 1.4-11.2), and hyperlipidemia (aOR 1.8, 95% CI 1.2-2.9) were identified as independent predictors of hospital admission.ConclusionComorbidities and public insurance are predictors of more severe illness for patients with SARS-CoV-2. This study suggests that the disparities in severity seen in COVID-19 among African Americans and Hispanics are likely to be closely related to low socioeconomic status and chronic health conditions and do not reflect an independent predisposition to disease severity.

Objective To measure the association of race, ethnicity, comorbidities, and insurance status with need for hospitalization of symptomatic emergency department patients with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection. Methods This study is a cohort study of symptomatic patients presenting to a single emergency department (ED) with laboratory‐confirmed SARS‐CoV‐2 infection from March 7‐August 9, 2020. We collected patient‐level information regarding demographics, insurance status, comorbidities, level of care, and mortality using a structured chart review. We compared characteristics of patients categorized by (1) home discharge, (2) general hospital ward admission, and (3) intensive care unit (ICU) admission or death within 30 days of the index visit. Univariate and multivariable logistic regression analyses were performed to report odds ratios (OR) and 95% confidence intervals (95% CI) between hospital admission versus ED discharge home and between ICU care versus general hospital ward admission. Results In total, 994 patients who presented to the ED with symptoms were included in the analysis with 551 (55.4%) patients discharged home, 314 (31.6%) patients admitted to the general hospital ward, and 129 (13.0%) admitted to the ICU or dying. Patients requiring admission were more likely to be Black or to have public insurance (Medicaid and/or Medicare). Patients who were admitted to the ICU or dying were more likely aged ≥ 65 years or male. In multivariable logistic regression, old age, public insurance, diabetes, hypertension, obesity, heart failure, and hyperlipidemia were independent predictors of hospital admission. When comparing those who needed ICU care versus general hospital ward admission in univariate logistic regression, patients with Medicaid (OR 2.4, 95% CI 1.2–4.6), Medicare (OR 4.2, 95% CI 2.1–8.4), Medicaid and Medicare (OR 4.3, 95% CI 2.4–7.7), history of chronic obstructive pulmonary disease (OR 2.2, 95% CI 1.2–4.2), hypertension (OR 1.7, 95% CI 1.1–2.7), and heart failure (OR 2.6, 95% CI 1.4–4.7) were more likely to be admitted into the ICU or die; Black (OR 1.1, 95% CI 0.4–2.9) and Hispanic/Latino (OR 1.0, 95% CI 0.6–1.8) patients were less likely to be admitted into the ICU; however, the associations were not statistically significant. In multivariable logistic regression, old age, male sex, public insurance, and heart failure were independent predictors of ICU care/death. Conclusion Comorbidities and public insurance are predictors of more severe illness for patients with SARS‐CoV‐2. This study suggests that the disparities in severity seen in COVID‐19 among Black patients may be attributable, in part, to low socioeconomic status and chronic health conditions.

Objective This study analyzed physician treating behavior through the use of a multiplex gastrointestinal polymerase chain reaction (GI PCR) test compared with usual testing in emergency department (ED) patients with suspected acute infectious diarrhea to assess differences in antibiotic management. Methods A prospective, single‐center, randomized control trial was designed to investigate antibiotic use in ED patients with moderate to severe suspected infectious diarrhea, comparing those who received GI PCR to those who received usual testing. ED patients with signs of dehydration, inflammation, or persistent symptoms were randomized to either the experimental arm (GI PCR) or the control arm (usual testing or no testing). Results A total of 74 patients met study criteria and were randomized to either the experimental GI PCR arm (n = 38) or to the control arm (n = 36). Participants in the GI PCR arm received antibiotics in 87% of bacterial or protozoal diarrheal infections (13/15) whereas those in the control arm received antibiotics in 46% of bacterial or protozoal infections (6/13) ( P value 0.042) with 2‐proportion difference 0.41 (95% confidence interval 0.07 and 0.68). Conclusions ED use of multiplex GI PCR led to an increase in antibiotic use for bacterial and protozoal causes of infectious diarrhea compared to usual testing. This increase in antibiotics appears to be appropriate given patients’ moderate to severe symptoms and a definitive identification of a likely bacterial or protozoal cause of symptoms. Results should be interpreted with caution because of the small sample size.

Objective The objective of this study was to assess the 1‐year outcomes of emergency department (ED) patients with complicated gallstone disease, including surgery rates, initial admission rates, ED revisits, repeat hospitalizations, and cost. Methods Using 3 linked statewide databases from the Maryland Healthcare Cost and Utilization Project, we identified patients with a primary diagnosis of complicated gallstone disease treated in an ED between 2016 and 2018. We measured the healthcare use and direct costs in the ambulatory surgery, inpatient, and ED settings for 1 year after the initial ED visit. Finally, we performed a multivariate logistic regression analysis comparing initially admitted versus discharged patients. Results Of the 8751 patients analyzed, 86.8% were admitted to the hospital and 13.2% were discharged on their initial ED visit. Of the admitted patients, 78.7% received a cholecystectomy during the initial hospitalization plus 6.1% at a later date; of the discharged patients, 41.5% received a cholecystectomy. Admitted patients demonstrated lower recurrent gallbladder complications compared with those discharged (7.5% vs 44.5%), fewer ED revisits (4% vs 20.3%), and fewer repeat hospitalizations (4.5% vs 16.7%). Despite this, the 1‐year cost in the admitted patients was higher ($9448 vs $2933). Obesity, age, and mood disorders but not race, ethnicity, or zip code were associated with admission at initial ED visit. Conclusions In our single‐state analysis of ED patients with complications of gallstone disease, most patients are admitted on the initial visit and receive a cholecystectomy during that hospitalization. The discharged group had higher rates of 1‐year complications, ED revisits, and repeat hospitalizations but lower cost.
