Development and Validation of a Nomogram for Predicting Multidrug-Resistant <i>Pseudomonas Aeruginosa</i> Pneumonia in Hospitalized Patients.

In this study, we developed and validated a predictive model for MDR-PA pneumonia risk by integrating host comorbidities, iatrogenic interventions, and antimicrobial exposure. The model demonstrates potential utility in early identification of high-risk patients and may inform antimicrobial stewardship strategies in regions with predominant cephalosporin/aminoglycoside resistance patterns.
