Abstract

Introduction- COVID -19 now become pandemic disease andChest computed tomography (CT) has very important role in diagnosis and characterizing the Covid patient severity by CT severity score.
Objectives:  The main purpose of this study was to evaluate the performance of MDCT in identifying & categorising the severity of COVID-19 inpatients.
Methods: This is retrospective cohort study and is performed on about 512 hospitalized COVID-19 patients in IGIMS from 15 April to July 2021. The CT severity score was assessed by two independent radiologists by involvement of percentage of area of each lobe of both lung parenchyma on HRCT lung. All admitted RT-PCR positive patient whose HRCT chest done in IGIMS were included in this study and OPD RT-PCR positive patient (COVID positive) & RT-PCR positive (COVID positive) patient with previous history of chronic lung disease, Tuberculosis, Lung mass, bronchiectasis etc were excluded in this study.
Results- In our study, Male (72.5%) are more affected in comparison to female (27.5%) and most of the patient are above the forth decade (69.5 %). Most patients are presented with severe CT severity score, i.e. > 15 CT severity score (about 41 percent) and about 20 percent & 22 percent present with mild & moderate CT severity score. Males are present with more CT severity than female.
Conclusion- Our studies show that older age group male patient (> 40 year) more affected in second peak of covid-19 and patient with chest involvement presented with severe CT severity score, so more mortality was noted , however this study is retrospective, needs prospective study for better correlation.
