Deterioration in Quality of Life among COVID-19 Survivors: Population-Based Cohort Study

TL;DR

This study finds that about a third of South Korean COVID-19 survivors experienced a decline in quality of life, with factors like rural living and ICU admission increasing the risk.

Contribution

The study provides population-based evidence on QOL deterioration among COVID-19 survivors and identifies sociodemographic and clinical factors associated with it.

Findings

32.6% of 325,666 COVID-19 survivors in South Korea experienced worsening quality of life.

Rural residence, ICU admission, and higher self-payment were linked to increased QOL deterioration.

Older age and vaccination were associated with reduced QOL worsening.

Abstract

We aimed to examine the prevalence of, and factors associated with, quality of life (QOL) worsening among coronavirus disease 2019 (COVID-19) survivors. This population-based retrospective cohort study used data from the Korea Disease Control and Prevention Agency and the National Health Insurance Service in South Korea. A total of 325,666 COVID-19 survivors were included in this study. Among them, 106,091 (32.6%) survivors experienced worsening QOL after COVID-19. Specifically, 21,223 (6.5%) participants experienced job loss, 94,556 (29.0%) experienced decreased household income, and 559 (0.2%) acquired new disabilities. In the multivariable logistic regression model, living in rural areas (odds ratio [OR]: 1.02; 95% confidence interval [CI]: 1.01, 1.04; p = 0.009), intensive care unit admission (OR: 1.08, 95% CI: 1.02, 1.15; p = 0.028), and increase in self-payment by 100 USD (OR: 1.02, 95% CI: 1.02, 1.02; p < 0.001) were associated with increased QOL worsening after COVID-19. Old age (OR: 0.99, 95% CI: 0.98, 0.99; p < 0.001), first vaccination (OR: 0.89, 95% CI: 0.86, 0.93; p < 0.001), and second vaccination (OR: 0.95, 95% CI: 0.93, 0.96; p < 0.001) were associated with decreased QOL worsening after COVID-19. Approximately one-third of COVID-19 survivors in South Korea who were admitted to hospitals or monitoring centers experienced QOL worsening.
