II. Indications
- Community Acquired Pneumonia Assessment for Disposition (Outpatient, Inpatient or ICU admission)
III. Criteria: Assign one point for each of positive criteria
- Confusion
- Blood Urea Nitrogen (BUN) >20 mg/dl
- Respiratory Rate 30 breaths/min or higher
- Systolic Blood Pressure <90 mmHg or Diastolic Blood Pressure <60 mmHg
- Age 65 years or older
IV. Interpretation
- Score 0-1: Outpatient management (30 day mortality <2.1%)
- Score 2: Inpatient management (30 day mortality 9.2%)
- Score 3: Intensive Care management (30 day mortality 15-40%)
V. Efficacy
- Poor Test Sensitivity (use other prediction tools for low scores)
- High Test Specificity (strongly consider ICU admission for higher scores)
VI. Disadvantages
- When used as a triage tool (for hospitalization), misses borderline cases (low Test Sensitivity)
- Does not include Hypoxia in its criteria
- Requires Blood Urea Nitrogen (remainder of criteria may be identified bedside)
