Do Covid-19 patients needing ICU admission have worse 6 months follow up outcomes when compared with hospitalized non-ICU patients? A prospective cohort study
Abstract
Introduction
Studies focus on pathogenesis, clinical manifestations, and complications during the early phase of the coronavirus disease-19 (COVID-19). Long-term outcomes of COVID-19 patients who discharge intensive care unit (ICU) are unclear.
Objectives
We investigated the effect of COVID-19 on lung structure, pulmonary functional, exercise capacity and quality of life in patients discharge from ICU and medical ward.
Methods
A prospective single-centre study conducted in PCR confirmed COVID-19 patients who has been discharged from University of Health Sciences, Dr. Suat Seren Chest Disease and Thoracic Surgery Teaching and Research Hospital between 15 January and 5 March 2021. Patients who followed up for more than 48 hours in ICU and more than 72 hours in medical ward were included the study. Computed tomography scores, pulmonary functional tests (PFT), 6-min walking distance and health related quality of life by SF-36 were compared between ICU and medical ward patients at 6 months after discharge.
Results
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.
Conclusion
A number of COVID-19 survivors especially with severe disease could not fully recover after 6 months of hospital discharge.
