Objective: Multiple states have reported increases in opioid overdose deaths during the coronavirus disease 2019 (COVID-19) pandemic, however little is known about opioid-related presentations to the emergency department (ED). Methods: This was a time series analysis of visits to 7 EDs in greater Chicago, Illinois from October 20, 2019 to July 25, 2020. We compared the number of ED visits for opioid-related diagnoses in the time period preceding the World Health Organization pandemic declaration (prepandemic period, October 20, 2019–July 3, 2020) to the time period following the World Health Organization declaration (pandemic period, March 8, 2020 to July 25, 2020) using a single-group interrupted time series analysis with Newey-West standard errors. We also present data on alcohol-related ED visits for comparison. Results: We evaluated a total of 177,405 visits across the 7 EDs during the study period. The mean number of weekly ED visits in the prepandemic and pandemic periods was 4841 and 4029 weekly visits, respectively. In the interrupted time series analysis, there was no significant immediate effect of the pandemic start on opioid-related ED visits (−0.44 visits per 1000 ED visits, 95% CI −2.47 to 1.58, P = 0.66), however, there was a significant immediate effect of the pandemic start on alcohol-related ED visits (−4.1, 95% CI: −8.25 to −0.01, P < 0.05). Conclusions: Despite reductions in overall ED visit volumes and alcohol-related visits during COVID-19, the number of opioid-related visits was not significantly reduced during the early pandemic. These data reinforce the need to provide comprehensive treatment services for opioid use disorder during the co-occurring COVID-19 and opioid crises.
Background The diagnosis of SARS-CoV-2-associated multisystem inflammatory syndrome in adults (MIS-A) requires distinguishing it from acute COVID-19 and may impact clinical management. Methods In this retrospective cohort study, we applied the U.S. Centers for Disease Control and Prevention case definition to identify adults hospitalized with MIS-A at six academic medical centers during March 1, 2020–December 31, 2021. MIS-A patients were matched on age group, sex, site, and admission date at a 1:2 ratio to patients hospitalized with acute symptomatic COVID-19. Conditional logistic regression was used to compare demographics, presenting symptoms, laboratory and imaging results, treatments administered, and outcomes between cohorts. Results Through medical record review of 10,223 patients hospitalized with SARS-CoV-2-associated illness, we identified 53 MIS-A cases. Compared with 106 matched COVID-19 patients, MIS-A patients were more likely to be non-Hispanic Black and less likely to be non-Hispanic White. MIS-A patients more likely had laboratory-confirmed COVID-19 ≥ 14 days prior to hospitalization, more likely had positive in-hospital SARS-CoV-2 serologic testing, and more often presented with gastrointestinal symptoms and chest pain. They were less likely to have underlying medical conditions and to present with cough and dyspnea. On admission, MIS-A patients had higher neutrophil-to-lymphocyte ratio, C-reactive protein, ferritin, procalcitonin and D-dimer, compared with COVID-19 patients. MIS-A patients had longer hospitalization and more likely required intensive care admission, invasive mechanical ventilation, and vasopressors. Mortality was 6% in both cohorts. Conclusions Compared with patients with acute symptomatic COVID-19, adults with MIS-A more often manifest certain symptoms and laboratory findings early during hospitalization. These features may facilitate diagnosis and management.
