Clinical, laboratory and radiological features and outcomes of moderate to severe COVID-19 patients: A descriptive retrospective study

Objective:To describe the clinical,laboratory and radiological characteristics and outcomes of moderate-to-severe coronvirus disease 2019(COVID-19)patients.Methods:We retrospectively analyzed 43 RT-PCR confirmed moderate-to-severe COVID-19 patients who were admitted to a tertiary care center.The primary composite outcomes were admission to intensive care unit,requirement of mechanical ventilation,and death.Results:The median age of the patients was 50 years,and 62.8%of the patients were male.Out of 43 patients,15(34.88%)were categorized as severe.A total of 26(60.47%)patients had 1 or more comorbidities[diabetes(34.88%)and hypertension(30.23%)].The median duration from the onset of symptoms to admission was 3 days,and the most common symptoms were dyspnoea(90.7%),cough(79.07%),fever(69.77%),and body ache(46.51%).Leucopenia was presented in 14(32.56%)patients,lymphopenia in 26(60.47%)patients,and monocytosis in 7(16.28%)patients.Besides,40(93.02%)patients had bilateral patchy nodular or interstitial infiltration on chest X-ray.The primary outcomes occurred in 20 patients(46.5%),among whom 8 required mechanical ventilation.The patients who had met the primary outcomes were older.They were prone to have at least 1 comorbidity(P=0.004),diabetes(P=0.01),hypertension,higher sequential organ failure assessment score,more tachycardia,lower SpO2,lower PaO2/FiO2,more thrombocytopenia,and more pancytopenia.Conclusions:This retrospective study identified several risk factors for poor outcomes in adults with COVID-19.In particular,older age,tachycardia,high SOFA score,low SpO2,low PaO2/FiO2,presence of comorbidities in form of diabetes and hypertension,thrombocytopenia,and pancytopenia at admission were associated with higher odds of ICU admission,a requirement of mechanical ventilation and in-hospital death.
