Factors influencing mortality in intracranial infections caused by carbapenem-resistant Klebsiella Pneumoniae.

ABSTRACT

It remains that intracranial infection has an alarming mortality and morbidity. Klebsiella pneumoniae (KP) have increasingly been isolated in ventriculitis and meningitis episodes. Intracranial infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) account for high mortality. To understand its clinical impact and related risk factors accurately are crucial in the management of bacterial intracranial infection. The retrospective study aimed to delineate the clinical risk of death from intracranial infection and analyze the risk factors. A total of 176 Klebsiella pneumoniae intracranial infectious patients were available to divide into CRKP group and carbapenem-susceptive Klebsiella Pneumoniae (CSKP) group. We performed survival analysis and estimate the time-varying effects of CRKP and CSKP infection on 30-day mortality. Infectious patients caused by CSKP was associated with lower mortality than CRKP group. The risk factors associated with death from intracranial infection caused by Klebsiella pneumoniae included SOFA scores, ventilator therapy, CRKP, and heart failure. Longer hospital stays are independently associated with lower mortality rates. Intracranial infection caused by CRKP was associated with excess mortality. Complex comorbidities mean higher mortality. Active supportive treatment is required for complicated patients with intracranial infections caused by carbapenem-resistant Klebsiella pneumoniae.
