ABSTRACT
Objective:
To investigate the related risk factors for the prognosis of hospital-acquired carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infections in elderly patients with critical illness.Methods:
Clinical data of elderly patients with nosocomial CRKP bloodstream infection in intensive care unit (ICU) from Jan. 2010 to Dec. 2016 were retrospectively analyzed. Patients were divided into the death and survival groups according to the prognosis. Clinical characteristics were compared between the two groups. Influencing factors for the prognosis of nosocomial CRKP bloodstream infections in elderly ICU patients were screened by multivariate Logistic regression analysis.Results:
A total of 119 elderly ICU patients with nosocomial CRKP bloodstream infection were enrolled. The overall ICU mortality rate was 62.2% (74/119 patients), among which the ICU mortality was lower in patients treated with tigecycline than without tigecycline treatment (50.0% or 25/50 vs. 71.0% or 49/69, χ2=4.770, P=0.029). And the ICU mortality was lower in patients with combination therapy than with mono-therapy (54.9% or 39/71 vs. 72.9% or 35/48, χ2=3.940, P=0.047). Multivariate Logistic regression analysis revealed that the administration of vasoactive drugs ( OR=25.545, 95% CI 9.743-52.242, P=0.001), and the resistance to tigecycline ( OR=8.990, 95% CI 0.957-24.488, P=0.049) were independent risk factors for ICU mortality. While the early initiated appropriate antibiotics treatment, which was defined as using at least one susceptible antibiotic within 48 hours ( OR=0.081, 95% CI 0.014-0.463, P=0.005), and appropriate antibiotics and adequate duration ( OR=0.785, 95% CI 0.631-0.977, P=0.030), were protective factors for the good outcome.Conclusions:
Nosocomial CRKP bloodstream infection in elderly ICU patients leads a high ICU mortality rate. The early initiated appropriate antibiotics treatment and optimum antibiotics duration could reduce the risk for death.
