Abstract

Objective: Chest CT has higher sensitivity in comparison to reverse transcription-polymerase chain reaction (RT-PCR) for COVID-19 diagnosis. We aim to identify the association of CT severity scores (CTSS) with lab markers and the need for oxygen. Methods: Cross-sectional observational study of 104 COVID-19 RT-PCR positive hospitalized patients. Patients underwent pulmonary CT, and their CTSS was calculated. SpO2, D-dimer and C-reactive protein (CRP) were also measured. The data was then collected and analyzed. Results: CT Severity Score (CTSS) was higher in patients above 50 years of age and males, though statistically insignificant. CTSS was positively correlated with D-dimer (p = 0.048) and oxygen requirement (0.000). However, HbA1C was lower in patients with higher CTSS. Conclusion: High CTSS correlates well with oxygen requirement, low SpO2, and high D-dimer but not with CRP and HbA1C. Our data suggest that CTSS can help predict disease outcomes by assessing disease severity.
