Variation in Mental Health, Sleep Quality and Quality of Life Following COVID-19 Hospitalization

COVID-19 causes instant and often prolonged effects with multisystemic and heterogeneous symptoms, significantly affecting the bio-psychosocial life of patients. In view of this, the present prospective cohort study aims to document the evolution of symptoms in hospitalized COVID-19 patients, monitoring variations in their mental and physical health for eighteen months after clinical recovery. A sample of 117 patients was examined at four distinct time points: at 2, 6, 12 and 18 months after discharge from the Pulmonology Clinic of the General University Hospital of Larissa (single-center approach). The data collection focused on psycho-physical symptoms, sleep disturbances and quality of life indicators. The study results revealed that over the 18-month period the participants gradually recovered both physically and psychologically, as well as regained pre-disease sleep patterns. However, substantial recovery was noted by month 6, followed by stabilization of their health status. However, a complete return to the pre-disease state of all assessed variables was not achieved, confirming and reinforcing the need for long-term follow-up and overall patient care.
