A study was just published describing 1591 ICU Covid patients in Lombardy, Italy, the largest study of its kind so far.

Some key stats:

82% of the patients were male

median age was 63 years

68% had at least one comorbidity, with hypertension being the most common

88% of the patients for which there was this kind of data were intubated (1150 total)

58% remain in the ICU

16% have been discharged from the ICU

26% died during the study

median length of stay of those who died in the ICU was 7 days

median length of stay for those who were discharged from the ICU was 8 days

@PulmCrit speculates about metabolic syndrome comorbidities

It’s interesting to note the proportion of proned patients here in light of our prior post on Luciano Gattinoni

In terms of limitations, data weren’t available for some of the patients and th sample of patients, being from the ICU, had a lot of respiratory distress from the start.
