Our aim is to correlate the clinical condition of patients with COVID-19 infection with the 25-point CT severity score by Chang et al. (devised for assessment of ARDS in patients with SARS in 2005).
Data of consecutive symptomatic patients who were suspected to have COVID-19 infection and presented to our hospital were collected from March to April 2020. All patients underwent two consecutive RT-PCR tests and had a noncontrast HRCT scan done at presentation. From the original cohort of 1062 patients, 160 patients were excluded leaving a total number of 902 patients.
The mean age was 44.2 ± 11.9 years (85.3% males, 14.7% females). CT severity score was found to be positively correlated with lymphopenia, increased serum CRP, d-dimer, and ferritin levels ( < 0.0001). The oxygen requirements and length of hospital stay were increasing with the increase in scan severity.
The 25-point CT severity score correlates well with the COVID-19 clinical severity. Our data suggest that chest CT scoring system can aid in predicting COVID-19 disease outcome and significantly correlates with lab tests and oxygen requirements.
我们的目的是将新型冠状病毒肺炎（COVID-19）感染患者的临床状况与Chang等人制定的25分CT严重程度评分（该评分于2005年用于评估严重急性呼吸综合征（SARS）患者的急性呼吸窘迫综合征（ARDS））相关联。
收集2020年3月至4月期间我院疑似感染COVID-19的连续有症状患者的数据。所有患者均接受了两次连续的逆转录聚合酶链反应（RT-PCR）检测，并在就诊时进行了非增强高分辨率计算机断层扫描（HRCT）。在最初的1062例患者队列中，排除了160例患者，最终共有902例患者。
平均年龄为44.2±11.9岁（男性占85.3%，女性占14.7%）。发现CT严重程度评分与淋巴细胞减少、血清C反应蛋白（CRP）、D-二聚体和铁蛋白水平升高呈正相关（<0.0001）。随着扫描严重程度的增加，氧气需求量和住院时间也在增加。
25分CT严重程度评分与COVID-19的临床严重程度密切相关。我们的数据表明，胸部CT评分系统有助于预测COVID-19疾病的预后，并且与实验室检查和氧气需求量显著相关。
