Clinical Observation and Prognostic Analysis of Patients With Bloodstream Infection.

BACKGROUND AND PURPOSE

The clinical prognosis of Klebsiella pneumoniae() bloodstream infection is poor, and the prevalence of drug-resistant bacteria makes clinical anti-infective treatment more challenging. This retrospective study evaluated the epidemiological characteristics of patients with , the risk factors for drug-resistant bacterial infection and death, and analyzed treatment options.

METHODS

Clinical data of 297 patients diagnosed with bacteremia between June 2014 and June 2019 were collected.

RESULTS

Intensive care unit hospitalization history, operation history, recent antibiotic use history, mechanical ventilation, and number of days hospitalized before bloodstream infection were found to be independent risk factors for drug-resistant bacterial infection. The risk of death for carbapenem-resistant infection was 2.942 times higher than that for carbapenem-sensitive infection. For extensively drug-resistant bacteremia patients, the mortality rate of combined anti-infective therapy was lower.

CONCLUSIONS

Clinicians should pay attention to patients with high-risk drug-resistant bacteria infection and administer timely anti-infection treatment. The findings of this study may provide some suggestions for early identification and standardized treatment of patients with bacteremia.
