Mortality of COVID-19 Admitted Patients on Mechanical Ventilators

Posted on

This brief was updated on June 26, 2020, with data as of June 18, 2020. Overall findings remain consistent, but the percentage of patients with an unknown outcome has decreased from 34% to 6%.

Here we examine the mortality of patients who received invasive mechanical ventilation as treatment for acute respiratory failure due to COVID-19. 

As of June 18, 2020, for COVID-19 positive patients age 19+ requiring invasive mechanical ventilation (n = 10,873), 4,989 (46%) were discharged from the hospital, 5,215 (48%) died, and 669 (6%) remain in the hospital.

The overall mortality rate in this sample of patients is between 48%-54%. Survival varies with age and sex, with younger and female patients having an increased likelihood of survival. Understanding ventilator survival rates by age and sex may be helpful for clinicians who are counseling patients and family members on likely outcomes with mechanical ventilation.


Data are pooled from 48 health systems representing 333 hospitals spanning 22 states and covering 42 million active patients.

  1. This is incredible. 10 times as large as any series of vented patients that I have seen. Do you have plans for more sophisticated analysis (e.g. Kaplan Meier) that would assign statistical significance and confidence intervals to these observations? These data are great but are not reaching the scientific/clinical community at large. And when they do, demand for this sort of analysis will increase.

    Thanks for posting. Very interesting.

    1. Thank you for your interest. We have tentative plans to analyze the ventilator data further. In particular, we want to look at patients with similar severities and compare those put on ventilators with those treated in other ways.

  2. Greetings:
    Bravo!
    I also want to congratulate you on the data collected. I am convinced that this will be a very valuable tool for the future of research in Healthcare. We usually have extreme difficulty collecting enough cases to have meaningful data, I imagine if we collect data with tools like Cosmos and combine this with AI the value of this would be incredible. When I participated in recent past in a multi-center study for difficult airway it took us an incredible long time of extremely long hours of collection for a total of 1,200 cases.
    I would be very interested in discussing this further.
    Sincerely,
