Abstract
COVID-19 is a disease caused by a novel coronavirus with no specific, standard treatment. We investigated the clinical data of COVID-19 patients admitted to King Fahad Specialist Hospital (KFSH) in Buraydah by comparing the patients who were treated early with favipiravir (within 3 days of admission) to patients who were treated after three days of admission or not treated. 165 patients were confirmed with PCR tests and admitted to KFSH for treatment. Comorbidities contributed significantly to in-creasing the length of stay in hospital at 11.4 +/- 0.8 days compared to patients with no comorbidities at 8.6 +/- 0.9 days (p = 0.041). A total of 103 patients were treated with favipiravir, and we found that early treatment with favipiravir (within 3 days) reduced the length of stay in hospital significantly (8.8 +/- 1.4 days) compared to patients who were treated after 3 days (13.3 +/- 4.6 days) (p = 0.0015). Moreover, patients with comorbidities in both early and late treatment groups had significantly higher average lengths of stay in hospital (11.2 +/- 0.9 days) compared to patients with no comorbidities (7.9 +/- 0.7 days) (p = 0.017). Interestingly, patients treated early with favipiravir (with comorbidities and without) stayed fewer days in hospital compared to those with late treatment (p = 0.021; a difference of 4.5 +/- 1.9 days; and p = 0.018; a difference of 4.2 +/- 1.7 days, respectively). In conclusion, our analysis indicates that early treatment with favipiravir can reduce the length of stay in hospital and improve clinical manifestations of COVID-19 patients.
