Summary

This study used artificial intelligence to analyze electronic health records from 100,000 COVID-19 patients across multiple hospitals. The goal was to identify factors that predict whether a patient would be hospitalized, need ICU care, or die. The study was terminated early, so findings may be limited.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors better predict which COVID-19 patients need hospital care or ICU support.
What could go wrong
The study was terminated early, so results may be incomplete. It only looked at past records, not testing new treatments.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of all patients with suspected COVID-19 infection, as captured in the patients' EHRs of the participating sites. Among the suspected COVID-19 cases, we will determine the following: * Confirmed positive cases (i.e., all patients who tested positive for COVID-19 ). * Confirmed negative cases (i.e., all patients who tested negative for COVID-19) * Possible cases (i.e., all patients with suspected COVID-19 but no/pending test results) To determine the characteristics of the patients according to their clinical outcome, we will study both the confirmed positive cases and all possible classes (with no/pending laboratory results) subpopulations

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)
