Factors associated with mortality in patients with COVID-19 receiving prolonged ventilatory support.
This study examined outcomes for COVID-19 patients who required mechanical ventilation from March 2020 through December 2021 across a system of 11 hospitals. A cohort of 600 patients were included, with in-hospital mortality of 40.3%. Increased age, prolonged ventilation, receiving corticosteroids, and being non-English speaking were associated with mortality. Intubations lasting longer than 21 days had a lower in-hospital mortality of 25.7%.

Declining COVID-19 case-fatality in Georgia, USA, March 2020 to March 2021: a sign of real improvement or a broadening epidemic?
This article examined whether declines in the crude US COVID-19 case fatality ratio is due to improved clinical care and/or other factors. The authors used multivariable logistic regression to examine associations between report month and mortality among confirmed and probable COVID-19 cases and hospitalized cases in Georgia from March 2020 through March 2021. Mortality risk was lowest in November 2020 compared to August 2020 and remained lower until March 2021. Among hospitalized cases, mortality risk increased in December 2020 and January 2021 before declining in March 2021. The authors concluded that improved clinical management may have contributed to lower mortality risk.

Assessment of a crisis standards of care scoring system for resource prioritization and estimated excess mortality by race, ethnicity, and socially vulnerable area during a regional surge in COVID-19.
Researchers analyzed the association of a crisis standards of care (CSOC) scoring system with resource prioritization and estimated excess mortality by race, ethnicity, and residence in a socially vulnerable area during the COVID-19 pandemic. Using data from 6 hospitals in greater Boston, Massachusetts, they found that a CSOC priority score resulted in lower prioritization of Black patients to receive scarce resources. Also, a model using a random lottery resulted in more estimated excess deaths overall without improving equity by race.

Medicaid expansion and drug overdose mortality during the COVID-19 pandemic in the United States.
This study examined trends in overdose mortality nationally and by state Medicaid expansion status from 2013 to 2020. Using data from the CDC’s WONDER database, findings showed that the increase in drug or opioid overdose deaths experienced during the first year of the COVID-19 pandemic was similar in states with and without Medicaid expansion.

County-level impact of the COVID-19 pandemic on excess mortality among U.S. veterans: a population-based study.
This study investigated the county-level impact of the COVID-19 pandemic on excess mortality among U.S. veterans. The authors queried Veterans Health Administration (VHA) administrative data on demographics and comorbidities for 11.4 million enrollees during 2016-2020. Eight mortality prediction models at the county-level were used including Poisson, Poisson quasi-likelihood, negative binomial, and generalized estimating equations. All models demonstrated excellent agreement between observed and predicted mortality. An excess mortality rate of 13% in 2020 was found, which corresponds to 50,299 excess deaths. Despite mortality risk factors of veterans, their excess mortality rate was slightly lower than the general population.
