P5‐91: Clinical characteristics and mortality risk in patients with severe COVID‐19

toms has not yet been clarified. Methods: For COVID19 patients who were admitted to our hospital from April 2020, the physical symptoms that occurred from the day of onset to the day of discharge were recorded. We conducted a telephone interview survey on the presence or absence of persistent symptoms and delayed symptoms 30 and 60 days after discharge. In addition, we divided the group into those who developed pneumonia and those who did not, and examined the relationship with the symptoms of COVID-19. Results: The mean age was 59 years, 17 males and 22 females, with an average hospital stay of 15 days. The initial symptoms were fatigue, sore throat, cough, dyspnea, and arthralgia, and the symptoms that persisted during the recovery period were fatigue, loss of appetite, anosmia, and ageusia. Hair loss was observed in the delayed symptoms, but only in a few patients. There was no statistically significant difference in the association between initial and persistent and delayed symptoms and pneumonia, but there was a tendency for more symptoms in the group without pneumonia. Conclusions: The present study shows that most patients requiring hospitalization for COVID-19 still have persistent symptoms after being discharged and it’s potentially reduce patients’ QOL and require treatments.
