Scoring: Risk of mortality (for 1 month and 1 year)
1. Age (in years)
  1. ADD one point for each year of age
2. Systolic Blood Pressure for 1 month (and 1 year) risk
  1. SUBTRACT 30 points (20 for 1 year risk) SBP <90 mmHg
  2. SUBTRACT 35 points (25 for 1 year risk) SBP 90-99
  3. SUBTRACT 40 points (30 for 1 year risk) SBP 100-119
  4. SUBTRACT 45 points (35 for 1 year risk) SBP 120-139
  5. SUBTRACT 50 points (40 for 1 year risk) SBP 140-159
  6. SUBTRACT 55 points (45 for 1 year risk) SBP 160-179
  7. SUBTRACT 60 points (50 for 1 year risk) SBP >180 mmHg
3. Respiratory Rate (in breaths per minute)
  1. ADD number of breaths per minute as points up to 45
4. Blood Urea Nitrogen (BUN as mg/dl)
  1. ADD level of BUN (mg/dl) as points up to 60
5. Serum Sodium <136 mEq/dl
  1. ADD 10 points
6. Hemoglobin <10 g/dl
  1. NOTE: Not used for assessing 1 month risk
  2. ADD 10 points if assessing 1 year risk
7. Comorbidity (1 year risk points noted if different)
  1. Cancer: ADD 15 points
  2. Cerebrovascular Disease: ADD 10 points
  3. Chronic lung disease: ADD 10 points
  4. Dementia: ADD 20 points (15 for 1 year risk)
  5. Hepatic Cirrhosis: ADD 25 points (35 for 1 year risk)
Interpretation: Mortality Risk per Point Scores
1. One Month Risk
  1. Points <69: 0.8% mortality over 1 month
  2. Points 69-82: 3.6% mortality over 1 month
  3. Points 83-96: 6.3% mortality over 1 month
  4. Points 97-113: 12.6% mortality over 1 month
  5. Points 114-195: 30.5% mortality over 1 month
2. One Year Risk
  1. Points <80: 9.0% mortality over 1 year
  2. Points 80-93: 17.7% mortality over 1 month
  3. Points 94-107: 29.1% mortality over 1 month
  4. Points 108-123: 42.1% mortality over 1 month
  5. Points 124-198: 66.3% mortality over 1 month
