CURB-65 Calculator
Assess pneumonia severity and determine hospitalization need using CURB-65 criteria
CURB-65 Assessment
Altered mental status or disorientation not present at baseline
Blood urea nitrogen level (1 point if >19 mg/dL or >6.8 mmol/L)
Breathing rate (1 point if ≥30 breaths per minute)
1 point if systolic <90 mmHg or diastolic <60 mmHg
Patient age (1 point if ≥65 years old)
CURB-65 Results
Score Breakdown
Treatment Recommendation
Low mortality risk (2.7%): Patient can be treated as outpatient with oral antibiotics and close follow-up.

This calculator is for educational purposes only and should not replace clinical judgment. The CURB-65 score is a guidance tool for pneumonia management. Always consider the patient's overall clinical condition, comorbidities, and social factors when making treatment decisions. Consult with healthcare professionals for all medical decisions.
Example Calculation
Community-Acquired Pneumonia Patient
Confusion: No (Score: 0)
BUN: 25 mg/dL (Score: 1 - >19 mg/dL)
Respiratory Rate: 32 breaths/min (Score: 1 - ≥30)
Blood Pressure: 105/70 mmHg (Score: 0 - normal)
Age: 72 years (Score: 1 - ≥65 years)
Result
CURB-65 Score: 0 + 1 + 1 + 0 + 1 = 3
Mortality Risk: 14.0%
Recommendation: Hospitalization Required
CURB-65 Criteria
Confusion
New onset mental confusion
Urea
BUN >19 mg/dL (>6.8 mmol/L)
Respiratory Rate
≥30 breaths per minute
Blood Pressure
SBP <90 or DBP <60 mmHg
Age

Mortality Risk & Management
Understanding CURB-65 Score
What is CURB-65?
CURB-65 is a validated clinical prediction rule for assessing the severity of community-acquired pneumonia (CAP). It helps clinicians determine the appropriate treatment setting (outpatient vs. hospital vs. ICU) and estimate mortality risk.
Clinical Applications
- •Pneumonia severity assessment
- •Hospitalization decision making
- •Mortality risk stratification
- •Treatment intensity guidance
Score interpretation
Outpatient treatment appropriate
Consider short-stay hospitalization
Hospitalization required, consider ICU for 4-5
Note: CURB-65 is specifically validated for community-acquired pneumonia. Consider clinical judgment, comorbidities, and social factors in treatment decisions.
