ABSTRACT

Objective: To evaluate the association of CT scan severity in-terms of severity score and characteristic of different lesions on admission in predicting the outcome of COVID pneumonia.

Study Design: Retrospective cross-sectional observational study

Place and Duration of Study: This study was conducted at the Department of Pulmonology, Recep Tayyip Erdogan Hospital, Muzaffargarh from May 2020 to December 2021.

Materials and Methods: Data of 209 patients was obtained from hospital record after clearance from hospital ethical board. Main variables of study were CT severity score, smoking status, total leukocyte count, lymphocyte count, ICU admission, LDH, CRP, ferritin, clinical stage of disease, mechanical ventilation and final outcome (discharge or death). SPSS version 24 was used for data analysis.

Results: ICU admission was needed in 11.8% mild disease stage, 16.9% in moderate stage and 20.0% in severe stage (P<0.001). Mechanical ventilation was given in 5.8% in mild, 10.8% in moderate and 8.0% in severe stage (P<0.001). In mild stage 58.8% patients discharged at room air, in moderate stage 78.5% and in severe stage 28.0% patients were discharged at room air (P<0.001). Death rate was high 40.0% in stage in which CT scan shows severe disease, in mild and moderate diseased stage death incidence was 17.7% and 4.6% respectively.

Conclusion: Computed tomography (CT) has an important role in diagnosis and assistance of clinicians during treatment of COVID-19 and it is a strong predictor of disease severity and final outcomes. Severity score predicted on CT scan is positively correlated with hospital stay, laboratory investigations and demand of oxygen.

Key Words: COVID-19 pneumonia, Clinical outcomes, Death, Severity of CT scan, Laboratory investigations.
