The probability of death decreased by 18.2% from March to August 2020, even when adjusting for changes in demographics and clinical severity.Adjusted mortality from COVID-19 decreased from 25.6% in March 2020 to 7.6% in August 2020.Journal of Hospital Medicine (October 23, 2020). Trends in COVID-19 risk-adjusted mortality rates.

In-hospital survival for people admitted to HDU and ICU with COVID-19. ![]() Limitations: Reporting delays may have led to incomplete ascertainment of death in more recent weeks, although all eligible patients had a minimum of 30 days follow-up. Survival was estimated controlling for age, sex, ethnicity, major comorbidities, and geographical region. The primary outcome was in-hospital 30-day all-cause mortality. Methods: Retrospective cohort study among 21,082 adults ≥18 years with severe COVID-19 admitted to HDU or ICU in England, between March 1 and June 27, 2020. After the week of March 29, 2020, survival improved per week by:.Unadjusted estimates of survival were lowest in early March 2020 (Figure). ![]() Critical Care Medicine (October 26, 2020).

Below we share two summaries of studies looking at survival in hospitalized patients with COVID-19 and potential reasons for increased survival from COVID-19 as the pandemic has progressed.Ī. ![]() Understanding changes in survival from COVID-19 and assessing where and in what populations there have been improvements in mortality rates is important to learn what more can be done to improve outcomes.
