Revision as of 16:06, 28 July 2023

Background

  • Originally developed to predict mortality with Pseudomonas aeruginosa bacteremia
  • Now used more broadly for mortality from infections more generally
  • A modified Pitt bacteremia score (mPBS) also exists[1]

Components

  • Measured at onset of bacteremia
Criterion Points (original) Points (modified)
Fever (°C)
    ≤35 or ≥40 2
    35.1-36.0 or 39.0-39.9 1
    36.1-38.9 0
Hypotension: drop by >30 SBP or >20 DBP, or vasopressors, or SBP <90 2 2
Mechanical ventilation 2 2
Cardiac arrest 4 4
Mental status
    Alert 0 0
    Disoriented 1 1
    Stuporous/comatose 2 2
    Comatose 4 4
Dialysis 2

Interpretation

  • ≥4 usually used as a cutoff for increased risk of death
Mortality predicted by PBS for various infections.
