Research Square(2020)
Abstract
Abstract Background: As we know, some patients with Coronavirus disease 2019 (COVID-19) may stay longer in the hospital, but whether the different hospitalization days are associated with different clinical features is not clear yet. Methods: This study is a single-centered, observational and retrospective case series.97 patients with COVID-19 were divided into two groups:patients with hospitalization for more than 20 days (Group1,n=35)and those with hospitalization for less than 20 days (Group2,n=62).Data were collected Results Acute Respiratory Distress Syndrome(ARDS) and Hospital acquired pneumonia (HAP)were more common in Group1 than in Group2 . There were more patients administered quadruple antiviral therapy in Group1 than in Group2 . In group1, 14.3% patients’ specimens showed positive again after they were discharged from the hospital.Compared with Group2,Group1 had higher percentages of oxygenation index<300mmHg leucopenia and lymphopenia. In Group1, 19 patients were treated with chloroquine phosphate,whose nucleic acid tests were negative soon,but 5 patents who hadn’t used the medicine had positive testing again . Conclusions: COVID-19 patients with longer hospitalization are more severe and need more quadruple antiviral therapy ;For patients who don't use chloroquine phosphate, the nucleic acid tests are more likely to return to positive again even if they have no symptoms at that time .
