Quality of life, depression, and anxiety in survivors of critical illness from a greek ICU. A prospective observational study

The physical and psychological consequences of critical illness may affect intensive care unit survivors for up to five years, and hence, health-related quality of life has emerged as an important measure of outcome in this population. We aimed at investigating the quality of life, the presence of anxiety and depression symptoms, and the correlations of clinical and psychological parameters with the quality of life scores in survivors of critical illness one year after discharge from intensive care. Widely used scales that have been validated for the Greek population were used. One thousand two hundred and seventy (1270) patients were assessed for eligibility. Inclusion criteria were age between 18 and 68 years and the presence of critical illness requiring endotracheal intubation and mechanical ventilation for more than three days. One hundred and four (104) patients were included in the final analysis; forty-nine age and sex-matched healthy volunteers were included for comparison. One year following intensive care unit discharge, survivors of critical illness had impaired quality of life scores, as measured with the WHOQOL-Bref, compared to healthy subjects (p < 0.001 for the physical and psychological domains, and p = 0.006 for the domain of social relationships). In addition, we found that quality of life scores were significantly lower in patients with comorbidities (p < 0.01), and correlated with the duration of ICU stay (r = −0.19, p = 0.04) and with the presence of symptoms suggestive of depression (r = −0.66, p < 0.0001) and post-traumatic stress disorder (r = −0.61, p < 0.0001). Approximately one-third of our patients scored high in the CES-D scale for depression, while the majority of them scored high in the STAI scale for anxiety symptoms. © 2021 by the authors.
