Guo et al reported the MuLBSTA score for predicting mortality in a patient with viral pneumonia. The authors are from multiple institutions in China.
MuLBSTA is an acronym for score parameters.
Patient selection: viral pneumonia
Outcome: mortality
Parameters:
(1) multilobar infiltrate (Mu)
(2) absolute lymphocyte count (L)
(3) bacterial coinfection (B)
(4) acute smoker (S)
(5) hypertension (T)
(6) age in years (A)
Parameters

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 20
• A score >= 12 was associated with high risk for mortality within 100 days.
Performance:
• The sensitivity was 77% and specificity 78%.
• The area under the ROC curve is 0.81.
