[Pathogens in Bloodstream Infection in Patients with Hematological Diseases: Retrospective Analysis].

OBJECTIVE

To analyze the distribution and drug resistance of pathogens sampled from the patients with bloodstream infection in the department of hematology of PLA General Hospital, so as to provide evidences for clinical prevention and control infection.

METHODS

From January 2014 to December 2017, A total of 286 cases-time positive blood culture samples from 212 patients in the department of hematology of the General Hospital of Chinese PLA were collected. The clinical characteristics of patients and the distribution and drug resistance of pathogens were analyzed retrospectively.

RESULTS

182(63.64%) bacterial strains were Gram-negative, and the other 104(36.36%) were Gram-positive. There were 88 strains of Escherichia coli(30.77%), 34 strains of Pseudomonas aeruginosa(11.89%), 26 strains of Klebsiella pneumoniae(9.09%), 25 strains of Staphylococcus epidermidis(8.74%), 20 strains of Gram-positive rods(6.99%), 16 strains of Staphylococcus hominis(5.59%), 11 strains of Etaphylococcus haemolyticus(3.85%), 10 strains of Staphylococcus aureus(3.50%), 6 strains of Staphylococcus capitis(2.10%), 5 strains of Acinetobacter baumannii(1.75%) and so on. Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae as Gram-negative bacteria were sensitive to amikacin. Staphylococcus epidermidis and Staphylococcus aureus as Gram-positive bacteria were sensitive to vancomycin and nitrofurantoin.

CONCLUSION

The blood culture patients with bloodstream infection in department of hematology of our hospital confirmed that more infections are Gram-negative. The clinicians should choose suitable antibiotics according to the results of bacterial culture and drug sensitive test.
