Beta-lactam Resistant P. aeruginosa Prediction Score


This model predicts the risk of resistance to antipseudomonal beta-lactams among respiratory and bloodstream isolates of Pseudomonas aeruginosa and other non-fermenting gram-negative bacilli (NFGN) such as Acinetobacter baumanii, etc.

It is particularly useful in critically-ill patients with risk of infections due to P. aeruginosa or NFGN in the respiratory tract (VAP) or bloodstream (prolonged hospitalization or severely immunecompromised hosts with qSOFA score ≥2)

Select All Applicable Risk Factors

  • Antipseudomonal beta-lactams include piperacillin-tazobactam, ceftazidime, cefepime, meropenem, and imipenem

  • Resistance to any of these agents confers beta-lactam resistant P. aeruginosa
