COVID-19: opacification score is higher in the right lung and right lung involvement is a better predictor of ICU admission

[摘要] The global response to coronavirus disease 2019 (COVID-19) has resulted in a wealth of research. The accrual of data through electronic health records (EHR) facilitates the efficient interrogation of datasets. Indeed, many issues of relevance to the COVID-19 response have been explored in this way, the impact of ethnicity or angiotensin-converting enzyme inhibition on outcomes, to name but two [1, 2]. Large teaching hospitals in the capital were at the forefront of the COVID-19 outbreak in the UK, with over 1000 patients admitted in under 1 month. Research teams mobilised quickly to understand this new and unprecedented disease. We extracted data from our EHR to build a risk score that predicted critical care admission or death. The model included demographics, laboratory data and chest radiographic (CXR) severity [3]. The extent of CXR abnormality was scored using an adapted radiographic assessment of lung oedema for COVID-19, as proposed by WONG et al. [4]. The severity score attributes a number between 0 and 4 to each lung depending on extent of consolidation or ground glass opacification as follows: a score of 0 corresponding to no disease; 1 corresponding to 75% extent.
