1- CURB-65 Community Acquired Pneumonia Severity Score

102 Not-Out Clinical Tool

BUN (Blood Urea Nitrogen, mg/dL ≥ 20)? No Yes
Respiratory Rate (≥30/min)? No Yes
Blood Pressure (SBP < 90 mmHg or DBP ≤ 60 mmHg)? No Yes
Age ≥ 65 years? No Yes

Information

• CURB- 65 is used to assess pneumonia severity and guide decision-making regarding the need for hospital admission or intensive care. Five factors are evaluated: Confusion, Urea levels, Respiratory rate, Blood pressure, and age 65 years or older. Higher scores indicating increased risk of mortality and the potential need for more intensive treatment. CURB- 65 is a valuable tool in both primary and secondary care settings for the management of community-acquired pneumonia.
• CURB- 65 Parameters:
• C: Confusion (new)
• U: Urea > 20 mg/dL
• R: Respiratory rate ≥ 30/min
• B: Blood pressure (SBP < 90 or DBP ≤ 60 mmHg)

65: Age ≥ 65 years

Score 0–5 → risk stratification for pneumonia severity.
