Long-term quality of life and work ability among severe COVID-19 survivors: A multicenter study.

Background: Coronavirus disease 2019 (COVID-19), is known for its variable severity and high infectivity. Though fewer than 15% of infected cases develop severe disease, a major proportion had prolonged stay in the intensive care unit (ICU). Prolonged ICU stay is known to have a long-term impact on behavior and quality of life. Methods: The current multicenter study adopted a cross-sectional design to analyze data from two tertiary care COVID-19 dedicated hospitals. All experimental procedures were approved by the ethics committee of the M.L.B Medical College. Participants were 20-60 age group who had been admitted to the ICU because of severe COVID-19 and had elapsed at least one and a half year since their discharge. After informed written consent the participants were assessed for: EUROHIS-QOL 8-item index; Workability Score; Quality of sleep; The major depression inventory (MDI) questionnaire; Generalized anxiety disorder 7 item scale (GAD-7); Current global health status score: an innovative subjective scale (1 -10) to determine the current global health status when 5 is the status before COVID-19. Findings: 491 participants were assessed, the median follow-up time after discharge from the hospital was 561·0 days (range, 548-580 days). The mean duration of ICU stay was 8.72 ± 2.85 days. There was significant reduction in the prevalence of obesity, diabetes, and hypertension as compared with discharge time. The mean of EUROHIS-QOL score, workability score, current global health status score was 3.28 ± 0.98, 6.87 ± 0.85, 4.53 ± 1.36 respectively. The mean MDI and anxiety scores were 4.12 ± 1.45 and 18.63 ± 3.28, respectively. Interpretation: Severe COVID-19 survivors have new-onset psychological disorders and sleep disturbances. Long term quality of life and work ability remains poor after prolong ICU admission secondary to severe COVID-19.
