Objective: Many observational studies have reported high morbidity and mortality associated with COVID-19 during hospitalisation. This study aimed to examine the longterm symptoms and related factors of patients hospitalised due to COVID-19.Materials and Methods: Clinical and laboratory characteristics of 266 patients who were followed up in the hospital with the diagnosis of COVID-19 were recorded. The patients were followed for an average of 14 weeks after discharge. The discharged patients were surveyed for their symptoms by calling.Results: On average, 14 weeks after being discharged, it was found that a least one symptom persisted in 27.4% (n =73) of 266 patients. The three most common symptoms after discharge were 38.3% (n = 28) cough, headache (36.9%, n = 27), shortness of breath (27.3%, n = 20), respectively. In multivariate analysis, it was found that symptoms persist more in patients with high CRP (C-reactive protein) and ferritin during hospitalisation (p: 0.03; p: 0.005, respectively). Conclusion: After COVID-19, it was observed that complaints continued after discharge in a significant number of patients. During hospitalisation, high ferritin and CRP levels were found to be associated with the persistence of symptoms. It was considered that symptoms associated with COVID-19 persist more in those with a high inflammatory response.
