Research article CT Chest findings and co morbid disease in mortality cases of COVID-19, in tertiary care centre - ( Retrospective analysis).

Abstract

Background: Since December 2019 Wuhan, China, has experienced an outbreak of COVID-19. The disease has spread to more than 150 countries around the world and the death number has constantly increased. CT scan finding with high severity score was increased and co-morbid disease was present in large number of death cases with COVID-19. We aimed to determine CT chest finding and co-morbid disease in mortality cases of COVID-19 in tertiary centre. Methods: 62 patients who died from COVID-19 were retrospectively included in this study. CT scan and co-morbid disease data of the patients were collected from medical records. The data was summarized. The CT severity score and associated co-morbid disease were analyzed.Results: Among   2892 patients in our hospital with COVID-19, 62 died. The mean age of patients was 65.35 years. Of which 43 (69%) were men and 19(31%) were women.GGO with consolidation was the most common feature for the lung. six lobes were  divided into total  20 segments. Each segment were scored 0, 1 and 2 depending on the status of involvement. All segments total scored 40. Severity of disease was categorized into Mild <13 (Figure.1), Moderate 13-19.5 (Figure. 2,3), Severe >19.5 score (Figure. 4,5,6,7,8). The CT severity score was rated as severe in 73% (45) of patients, moderate in 16% (10) patients, and mild in 11% (7) of patients. 58 patients (93.5%) had co-morbid disease. Among co morbid disease, 12 (19%) had DM, 23(37%) had Hypertension and 23(37%) had both DM and HTN. 12(19%) had other chronic illness accompanied with above co morbid diseases. 54 (90%) had fever, 36 (58%) had cough, 18 (29%) had breathlessness.Conclusion: Our findings suggest co-morbid disease increases the risk of in-hospital mortality in spite of low CT severity score following COVID-19 infection in comparison with no co-morbid disease.
