Utility of the PITT Bacteremia Score for Predicting Mortality in CRE Colonized and Infected Patients

Background: The Pitt Bacteremia Score (PBS) is used to predict 14-day inpatient mortality in bloodstream infections. This study evaluates whether PBS can also predict mortality in ICU patients colonized or infected with Carbapenem -resistant Enterobacterales (CRE). Methods: ICU patients with CRE were selected, and each PBS component was individually assessed. Outcomes were noted after 14 days, and a PBS cutoff score for mortality prediction was analyzed. Results: Of 30 patients, 26 (86%) expired and 4 (14%) survived. A PBS cutoff of ≥4 was associated with a significant increase in mortality. Conclusions: PBS ≥4 may be a valuable predictor of mortality in CRE-infected and colonized ICU patients."
