PulmonologyScore

BAP-65 Score for Acute Exacerbation of COPD

Predicts in-hospital mortality and risk of mechanical ventilation in patients with acute exacerbations of COPD (AECOPD) using four readily available variables: BUN, altered mental status, pulse rate, and age ≥ 65. Provides a simple bedside risk stratification tool for US hospital populations.
