Class I - Low Risk
Clinical Recommendation
Low risk. Consider outpatient management if other factors favorable. Low probability of needing mechanical ventilation.
Risk by Class
- Class 1 (Score 0): 0.3% mortality, 0.3% MV
- Class 2 (Score 1): 1.0% mortality, 0.2% MV
- Class 3 (Score 2): 2.2% mortality, 1.2% MV
- Class 4 (Score 3): 6.4% mortality, 5.5% MV
- Class 5 (Score 4): 14.1% mortality, 12.4% MV
Clinical Application
BAP-65 is validated for patients with acute COPD exacerbation. It helps predict need for invasive mechanical ventilation and in-hospital mortality, guiding ICU vs floor admission decisions.
Disposition Guide
