• •This single-center study revealed the epidemiologic and antimicrobial resistance data of bloodstream infections (BSIs) in Japan.•During the 5-year period, 2,105 patients with episodes of BSI were included the analysis.•We found that fungal BSI was significantly associated with 30-day mortality.•Extended-spectrum beta lactamase–producing isolates were associated with significant increased 30-day mortality. Few published data are available on the morbidity and mortality of bloodstream infections (BSIs) in Japan. We sought to investigate the epidemiology of BSIs, the involvement of antimicrobial resistance, and the factors that influence patient prognosis. This single-center study retrospectively evaluated patients who were found to have positive blood cultures at a tertiary teaching hospital between January 2012 and December 2016. A total of 2,105 patients with BSIs were included; 1,786 survived and 319 died, and the 30-day mortality rate was 15.2% over the 5-year study period. BSIs caused by yeasts were independently associated with 30-day mortality. The 30-day mortality rate of BSIs caused by extended-spectrum beta lactamase–producing gram-negative bacteria was significantly higher than that of BSIs caused by nonproducing bacteria. The differences in mortality may be caused by differences in the distribution of pathogens and in the delivery of health care. This study reported epidemiology and antimicrobial resistance data of BSIs in Japan and identified several risk factors associated with 30-day mortality. National surveillance of BSIs is required in Japan for comparison with other countries.
