Clinical Course of COVID-19 Patients according to hematological findings
A total of 1050 (79.5%) patients recovered during follow-up and were discharged. Median follow-up time was 7 (1-41) days for those patients in hospital. Five hundred and five (48.1%) of these patients were able to be discharged in less than 7 days. Five hundred and forty-five patients (51.9%) were followed up in the hospital for 7 or more days and were discharged after a maximum of 41 days. Median age was statistically significantly higher in patients who stayed longer in the hospital (p=0.001). The majority of the patients who were hospitalized for shorter periods consisted of women, while the proportions of both sexes were almost equal in longer hospitalization periods. The hemoglobin and thrombocyte level at the time of admission were statistically significantly higher in patients who were discharged in <7 days than in patients who were discharged in ≥7 days. The leukocyte, neutrophil, monocyte, eosinophile, basophile and ferritin values at the time of admission were statistically significantly lower in patients who were discharged in <7 days than in patients who were discharged in ≥7 days (Table 2).
After univariate analysis, among the factors that had p value <0.05 were taken to multivariate analysis. In multivariate analysis, age (p<0.001) and platelet counts (p=0.001) at the admission time were found to be independent factors related with hospitalization for a longer period of time.
