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.⁸ Therefore, it is likely that patients discharged after severe COVID-19 have issues that persist for long term. The current study aimed to assess the long-term impact of severe COVID-19 on the Quality of life (QOL), sleep pattern, behavior, and workability.

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.
