Clinical Features Predicting Mortality Risk in Patients With Viral Pneumonia: The MuLBSTA Score
Open accessAbstract
Objective The aim of this study was to further clarify clinical characteristics and predict mortality risk among patients with viral pneumonia. Methods A total of 528 patients with viral pneumonia at RuiJin hospital in Shanghai from May 2015 to May 2019 were recruited. Multiplex real-time RT-PCR was used to detect respiratory viruses. Demographic information, comorbidities, routine laboratory examinations, immunological indexes, etiological detections, radiological images and treatment were collected on admission. Results 76 (14.4%) patients died within 90 days in hospital. A predictive MuLBSTA score was calculated on the basis of a multivariate logistic regression model in order to predict mortality with a weighted score that included multilobular infiltrates (OR=5.20, 95%CI 1.41-12.52, p=0.010; 5 points), lymphocyte≤0.8*109/L (OR=4.53, 95%CI 2.55-8.05, p<0.001; 4 points), bacterial coinfection (OR=3.71, 95%CI 2.11-6.51, p<0.001; 4 points), acute-smoker (OR=3.19, 95% CI 1.34-6.26, p=0.001; 3 points), quit-smoker (OR=2.18, 95% CI 0.99-4.82, p=0.054; 2 points), hypertension (OR=2.39, 95% CI 1.55-4.26, p=0.003; 2 points) and age≥60 years (OR=2.14, 95% CI 1.04-4.39, p=0.038; 2 points). 12 points was used as a cut-off value for mortality risk stratification. This model showed sensitivity of 0.776, specificity of 0.778 and a better predictive ability than CURB-65 (AUROC = 0.773 vs 0.717, p<0.001). Conclusions Here, we designed an easy-to-use clinically predictive tool for assessing 90-day mortality risk of viral pneumonia. It can accurately stratify hospitalized patients with viral pneumonia into relevant risk categories and could provide guidance to make further clinical decisions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
