ĐÁNH GIÁ HỆ THỐNG THANG ĐIỂM TSS VÀ BRIXIA TRONG X-QUANG NGỰC Ở BỆNH NHÂN MẮC BỆNH COVID 19

Abstract

Objectives: Applying the TSS and Brixia chest X-ray score systems to assess severe acute respiratory failure due to Covid-19. Subjects and methods: Analytic prospective study. Study on 128 hospitalized patients with Covid-19 who had at least 2 x-rays at the time of admission and at discharge or transfer to other hospital. Results: Two radiologists read chest X-ray films according to 2 systems for TSS and Brixia scores. Two radiologists had good agreement index when scoring according to TSS and Brixia system (kappa 0.734 and 0.668). But when comparing those two systems between the two radiologists, the agreement level was average (kappa 0.584) because the two systems have different maximum scores (8 and 18 points). The TSS scoring system again missed many moderate and severe diseases with high risk of death. Conclusion: A scoring system is needed to evaluate chest X-rays especially during the Covid-19 pandemic. The TSS scoring system is easy to evaluate but easily misses the moderate and severe patients who have a higher risk of death than the Brixia system.
