In the present study, we aimed to correlate clinical and laboratory characteristics of hospitalized COVID-19 patients to disease outcome in Saudi Arabia.Materials and Methods: The present study included 199 COVID-19 patients admitted to King Fahd Specialist Hospital, Buraydah, Qassim, Saudi Arabia, from April to December 2020. Patients were followed-up until discharge either for recovery or death. Demographic data, clinical data and laboratory results were retrieved from electronic patient records.Results: Critical COVID-19 cases showed higher mean of age and higher prevalence of co-morbid conditions. Fifty-five patients died during the observation period. Risk factors for in hospital death for COVID 19 patients were leukocytosis (OR 1.89, 95% CI 1.008– 3.548, p = 0.081), lymphocytopenia (OR 2.152, 95% CI 1.079– 4.295, p = 0.020), neutrophilia (OR 1.839, 95% CI 0.951– 3.55, p = 0.047), thrombocytopenia (OR 2.152, 95% CI 0.852– 5.430, p = 0.085), liver injury (OR 2.689, 95% CI 1.373– 4.944, p = 0.003), acute kidney injury (OR 1.248, 95% CI 0.631– 2.467 p = 0.319), pancreatic injury (OR 1.973, 95% CI 0.939– 4.144, p = 0.056) and high D dimer (OR 2.635, 95% CI 0.747– 9.287, p = 0.091).Conclusion: Clinical and laboratory data of COVID-19 patients may help understanding the pathogenesis of the disease and subsequently improve of the outcome of patients by determination of the associated risk factors and recognition of high risk group who are more liable for complications and in hospital death. The present study put an eye on some parameters (laboratory and clinical) that should be alarming signs that the patient is at high risk bad prognosis.Keywords: clinical, outcomes, prognosis, COVID-19, Saudi Arabia
