PORT Score

PORT (Pneumonia Patient Outcomes Research Team) Score is a clinical prediction rule that medical practitioners use to calculate the probability of mortality among patients with community acquired pneumonia (CAP).

Use of this tool can diminish the variability in rates of hospitalization of patients with CAP and give guidance to which patients are high or low risk for complications.

The rule was derived from 14,199 adult inpatients with CAP. The rule was then validated with 38,039 inpatients and with 2,287 inpatients and outpatients in the Pneumonia Patient Outcomes Research Team (PORT) cohort study.

This tool derived a prediction rule that stratifies patients into five classes with respect to the risk of death within 30 days according to the following items:

Elements of the PORT Score:

  • Demographics
    • Enter Age [1 pt for every year of Age]
    • Female [-10 pts]
    • Nursing home resident [10 pts]
  • Comorbid Illnesses
    • Neoplastic disease [30 pts]
    • Liver disease [20 pts]
    • Congestive Heart Failure [10 pts]
    • Cerebrovascular disease [10 pts]
    • Renal disease [10 pts]
  • Physical examination findings
    • Altered Mental Status [20 pt]
    • Respiratory rate >=30/min [20 pts]
    • Systolic blood pressure <90 mmHg [20 pts]
    • Temp <35 or >=40°C (<95 or >=104°F) [15 pts]
    • Pulse >=125/min [10 pts]
  • Laboratory and Radiographic findings
    • Arterial pH <7.35 [30 pts]
    • BUN >=10.7 mmol/L (30 mg/dl) [20 pts]
    • Sodium <130 mEq/L [20 pts]
    • Glucose >=250 mg/dL (14 mmol/L) [10 pts]
    • Hematocrit <30% (0.3) [10 pts]
    • PaO 2 <60 mmHg [10 pts]
    • Pleural effusion [10 pts]

* BUN = Blood Urea Nitrogen

PaO 2 = Partial Pressure of Arterial Oxygen

PORT Score % risk of death within 30 days Treatment Recommended
Class I 0.1-0.4 Outpatient Treatment
Class II(<=70) 0.6-0.7 Outpatient Treatment with oral antibiotics typically recommended; in selected cases <24 hours admission and may be indicated (with traditional inpatient care)
Class III(71-90) 0.9-2.8 Outpatient Treatment with oral antibiotics typically recommended; in selected cases <24 hours admission and may be indicated (with traditional inpatient care)
Class IV(91-130) 8.5-9.0 Inpatient Treatment
Class V(>130) 27.1-31.1 Inpatient Treatment

This Data is in accordance to MedisGroups derivation, MedisGroups validation and overall Pneumonia PORT validation study.

Step 1:

This step determines whether the patient is in Class I or Class II-V. If no exclusionary criteria are present, the patient is Class I; otherwise the patient is Class II-V based upon the sum of items present.

To be Class I, the patient must have NONE of the following:

  • Age >50 yrs
  • Neoplastic disease
  • Congestive heart failure
  • Cerebrovascular disease
  • Renal disease
  • Liver disease
  • Altered mental status
  • Pulse >125/min
  • Respiratory rate >30 per minute
  • Systolic blood pressure<90 mmHg
  • Temp <35 or >=40°C (<95 or >=104°F)

If any of the above items are present we go to step 2 and calculate score.

Step 2:

  • For Class II, III, IV, V
  • Classification is on the basis of the total score computed by adding the scores of the items above.
