Association of mental health with clinical outcomes in hospitalized patients with moderate COVID-19

OBJECTIVE: To assess the association of depression and anxiety with clinical outcomes and laboratory markers among hospitalized patients with coronavirus disease 2019 (COVID-19). METHODS: A prospective cohort study in Wuhan, China was conducted in 205 adult hospitalized patients with a diagnosis of moderate coronavirus disease from admission through discharge or death. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). The primary outcome was the incidence of severe or critical COVID-19, and the secondary outcomes were increased length of hospital stay and altered laboratory markers during follow up. RESULTS: Among the 205 hospitalized patients (mean age 58 years; 51.7% male), 25 (12.2%) developed severe or critical COVID-19. According to the HADS scores, 51 (24.9%) and 92 (44.9%) of participants presented with clinically significant anxiety and depression, respectively. Using multi-variable adjusted Cox regression analysis, the adjusted hazard ratio of developing severe or critical COVID-19 associated with anxiety and depression was 1.55 (95% CI: 0.63, 3.80) and 4.28 (95% CI: 1.20, 15.30), respectively. The risk of developing severe or critical COVID-19 with both anxiety and depression was more than four times higher than in patients without anxiety or depression (HR, 4.05; 95% CI: 1.02, 16.00). In addition, both the trends of depression and anxiety were positively associated with a prolonged duration of hospitalization, and immune response was significantly decreased in patients with depression than those without. CONCLUSIONS: In patients having coronavirus disease, depression was associated with worse clinical outcomes. These findings highlight the importance of prevention and management of mental health problems in confronting the COVID-19 pandemic.
