A Novel Severity Scoring Derived from Chest Radiographic Findings in COVID 19 Patients Admitted to a COVID Care University Hospital in India

Abstract

Coronavirus (COVID 19) disease predominantly affects the Respiratory system and cause by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV2). It enters into the host cells via angiotensin-converting enzyme-2 (ACE-2), a part of the renin-angiotensin system (RAS) found in the epithelium of the nasal, lungs. Aim: Chest Radiographic findings in COVID-19 patients detected for COVID care. Applying the novel chest radiographic scoring in disease-spread patients is admitted to the COVID care center and its correlation with blood oxygen saturation (SpO2) and clinical severity. Objective: 1) To apply the novel chest radiographic scoring in patients of COVID 19 infection are admitted to our Covid Care Centre and 2) To apply its correlation with blood oxygen saturation (SpO2) and clinical severity. Results: 1) We found a moderate negative correlation between the chest radiographic score and SpO2. 2) Weak positive correlation between Clinical grading and CxR score. Conclusion: Chest radiographic score taking into account the nature of opacities and extent is useful in classifying the patients into mild-moderate, severe, and critical grades. Take-home Message: A chest radiograph can be used as a baseline radiological investigation in COVID 19 patients as it can help to triage them according to the severity and treat them accordingly.
