Abstract
Considering the paucity of data on long-term Health-Related Quality of Life (HRQoL) in coronavirus disease 2019 (COVID-19) intensive care unit (ICU) survivors, we present one-year follow-up results on patients’ HRQoL and compare them with those of the already reported 6-month follow-up. We conducted a prospective cohort study of patients in COVID-19 ICU between March and June 2020. A HRQoL analysis was performed six months and 1 year after discharge by means of a short-form-36 (SF-36) questionnaire. Hospital mortality in 403 ICU COVID-19 patients was 44.9%; further 4.0% died between hospital discharge and 6-month follow-up and only 0.5% died in the next six months. The median physical component of HRQoL increased from 43.7 (interquartile range (IQR): 31.7–52.7) at 6 months to 46.0 (IQR: 38.0–53.0) 1 year after hospital discharge (p = 0.007). In multivariable regression analysis, age >50 (odds ratio (OR) 0.270) and female sex (OR 0.144) were independently associated with reduced physical HRQoL 1 year after discharge. The median mental component of HRQoL increased from 50.6 (IQR: 42.0–55.8) at 6 months to 53.0 (IQR: 47.0–56.0) 1 year after discharge (p = 0.035), with no significant predictors. Increased HRQoL was associated with an improvement in patients’ physical status, role functioning, emotional well-being (all p < 0.001) and social functioning (p = 0.007). ICU COVID-19 patients’ HRQoL slightly improved 1 year after discharge, when compared to results of the 6-month follow-up. Medications received during ICU stay had no effect on physical or mental HRQoL.
