Abstract: | Background: This study was designed to determine changes in risk factors on the prognosis of patients during each period of the bloodstream infection (BSI) timeline. Methods: Through an integrated study of multivariable regressions with machine learning techniques, the risk factors for mortality during each period of BSI were analyzed. Results: A total of 302,303 inpatients who underwent blood cultures during 2011e2021 were enrolled. More than 8 % of BSI cases progressed to subsequent BSI, and risk factors were identified as gut colonization with vancomycin-resistant enterococci (aOR 1.82; 95 % CI 1.47e2.24), intensive care unit admission (aOR 3.37; 95 % CI 3.35e4.28), and current cancer chemotherapy (aOR 1.54; 95 % CI 1.36e1.74). The mean SOFA score of the deceased patients during the first 7 days was 10.6 (SD 4.3), which was significantly higher than those on days 8e30 (7.0 4.2) and after Day 30 (4.0 3.5). BSIs caused by Acinetobacter baumannii and Candida albicans were more likely to result in deaths of patients for all time periods (all, P < 0.001). BSIs caused by Enterococcus faecalis and Enterococcus faecium were associated with a poor outcome in the period after Day 30 (both, P < 0.001). Nonsusceptible phenotypes to b-lactam/b-lactamase inhibitors of Escherichia coli and Klebsiella pneumoniae influenced the prognoses of patients with BSI in terms of high mortality rates during both days 8e30 and after Day 30. Conclusion: Influence of microbiological factors on mortality, including BSI-causative microorganisms and their major antimicrobial resistance, was emphasized in both periods of days 8 e30 and after Day 30. |
