Can a bedside score flag deadly viral pneumonia?
Open access · cc by · source: Europe PMC
In 528 viral pneumonia admissions, MuLBSTA (cut-off 12) stratified 90-day mortality better than CURB-65 (AUROC 0.773 vs 0.717).

Key findings
76/528 (14.4%) died by 90 days. Top weighted factors included multilobular infiltrates (5 pts) and lymphopenia (4 pts). Sensitivity/specificity ~0.78 at cut-off 12.
Methodology
Recruited viral pneumonia patients, built a weighted logistic score (MuLBSTA) on a training split, and validated discrimination including vs CURB-65.
Limitations
Single-center derivation; score predicts risk, not treatment benefit from any specific therapy.
