Abstract:

Objective To analyze the risk factors and prognosis of bloodstream infection caused by carbapenem-resistant Klebsiella pneumoniae(CRKP),and to provide a reference for the control and prevention of nosocomial infection. Methods The clinical data of 281 patients with bloodstream infection caused by Klebsiella pneumoniae from July 2017 to July 2019 in Henan Provincial People's Hospital were analyzed retrospectively. The risk factors and prognosis of bloodstream infetction caused by CRKP was analyzed. Results There were 124 CRKP infection cases and 157 carbapenem-sensitive Klebsiella pneumoniae(CSKP) infection cases. The mortality rate and inpatient day in CRKP infection cases were higher than those in CSKP infection cases(P<0.05). The risk factors of bloodstream infection caused by CRKP included using antibiotics(carbapenems and enzyme inhibitors) before infection and invasive treatment. The prognosis of CRKP infection was poor. Conclusions Bloodsteam infection caused by CRKP has low cure rate and poor prognosis. Using antibiotics before infection and invasive treatment are the risk factors of bloodstream infection caused by CRKP. The rational use of antibiotics after infection is a protective factor for good prognosis.
