Recalibration and Validation of a Risk Scoring Tool to predict Multi-Drug Resistant Pseudomonas aeruginosa

Key Points

• The central aim is to improve the identification of multi-drug resistant Pseudomonas aeruginosa in ICU patients.
• Recalibration of a risk scoring tool based on 197 ICU patients with infections.
• Assessment of model performance using c-statistics, sensitivity, and specificity.
• Prevalence of multi-drug resistant Pseudomonas aeruginosa was 6%.
• Models demonstrated moderate discrimination with c-statistics ranging from 0.71 to 0.74.
• Sensitivity was low at 18%, while specificity was high at 94% to 96%.
