Doctors talked about new research on Twitter and shared new strategies in Facebook groups and on WhatsApp.

Doctors like Seth Trueger, an assistant professor of emergency medicine at Northwestern University, saw the position help patients get enough oxygen to avoid needing a ventilator.

Since March, physicians have also figured out other ways to help severely ill patients avoid ventilation.

Now, they’re primarily using remdesivir, and antiviral drug that appears to help COVID-19 patients recover more quickly, and the steroid dexamethasone, which helps improve the survival rate for patients on ventilators.

Most of the changes in doctors’ strategies over the past few months have been in patients who are severely ill.

If someone is sick enough to be hospitalized with COVID-19 but doesn’t need to be in intensive care, there still isn’t much doctors can do for them.

Doctors now are more vigilant to the threat from blood clots, which have appeared in many COVID-19 patients over the past months.

One lingering question, Hudspeth says, is figuring out how to keep those moderately ill patients from becoming severely ill.

Changes to treatment strategies for patients who are not severely sick have been harder to come by — in part because it’s riskier to try something new in that group.

Doctors aren’t shifting their practices as quickly as they were back in March and April, and Trueger says he thinks the next few months may be relatively stable
