Purpose: Pseudomonas aeruginosa bacteremia presents a severe challenge to hospitalized patients. However, to date, the risk factors for mortality among inpatients with P. aeruginosa  bacteremia in China remain unclear.
Patients and Methods: This retrospective multicenter study was performed to analyze 215 patients with culture-confirmed P. aeruginosa  bacteremia in five healthcare centers in China during the years 2012– 2019.
Results: Of 215 patients with P. aeruginosa  bacteremia, 61 (28.4%) died during the study period. Logistic multivariable analysis revealed that cardiovascular disease (OR=3.978, P =0.001), blood transfusion (OR=5.855, P < 0.001) and carbapenem-resistant P. aeruginosa  (CRPA) phenotype (OR=4.485, P =0.038) constituted the independent risk factors of mortality. Furthermore, both CRPA and multidrug-resistant P. aeruginosa  (MDRPA) phenotypes were found to be significantly associated with 5-day mortality (Log-rank, P < 0.05).
Conclusion: This study revealed a high mortality rate amongst hospitalized patients with P. aeruginosa  bacteremia, and those with cardiovascular diseases, CRPA and MDRPA phenotypes, should be highlighted and given appropriate management in China.
