Frailty Index Laboratory (FI-Lab) as predictor of poor outcomes for intra-hospital multidrug-resistant Klebsiella pneumoniae bloodstream infections: a single-centre retrospective cohort study
Retrospective cohort study evaluated FI-Lab's predictive ability for mortality and relapse in patients with CR-Kp BSIs, suggesting improved clinical decision-making.
Key Points
FI-Lab showed excellent predictive accuracy for mortality, with an AUC of 0.94.
Among 182 patients with CR-Kp BSIs, 48 died, showing a 26.3% mortality rate.
Each 0.10-point FI-Lab increase raised mortality risk by an HR of 2.07, indicating strong predictive power.
Further studies are needed to validate the FI-Lab's applicability in managing infections in fragile populations.
