Seventy patients were included final analyses and 31 of them discharged from ICU. ICU patients had higher CT scores than non-ICU patients at admission (17 vs 11) and follow up visit (6 vs 0). Two-three of ICU patients had at least one abnormal finding at control CT. Advanced age (OR 1.08, 95% CI 1.02-1.15) and higher CT score at admission (OR 1.13, 95% CI 1.01-1.27) were risk factors for having radiological abnormalities at control CT. 90% of the patients discharged from the ICU had at least one persistent symptom.
