This study was performed to understand these epidemiological data of BSI over the past 10\u00a0years in China.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Using a prospective nosocomial infection surveillance system, this study was retrospectively performed in one of the largest hospitals in China. The time trend was tested using the Cochran\u2013Armitage trend test in R Programming Language.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n From 2010 to 2019, there were totally 9381 episodes of BSI cases out of 1,437,927 adult-hospitalized patients in the hospital, the total proportion of BSI cases was 6.50\u2030 (6.50 episodes per 1000 adult-hospitalized patients) and the proportion had significantly decreased (8.24\u20136.07\u2030, time trend\n P<\/jats:italic>\n \u2009<\u20090.001). Among the 9381 episodes of BSI, 93.1% were bacteremia and others were fungemia (6.9%). As the most common species, the composition ratios of coagulase-negative\n staphylococcus<\/jats:italic>\n (25.6\u201332.5%),\n Escherichia coli<\/jats:italic>\n (9.8\u201313.6%) and\n Klebsiella pneumoniae<\/jats:italic>\n (5.3\u201310.4%) had been dynamically increased (all time trends\n P<\/jats:italic>\n \u2009<\u20090.05) and the proportion of\n Pseudomonas aeruginosa<\/jats:italic>\n had decreased (4.0\u20132.4%, time trend\n P<\/jats:italic>\n \u2009=\u20090.032). However,\n Staphylococcus aureus<\/jats:italic>\n (3.3\u20133.1%) and\n Acinetobacter baumannii<\/jats:italic>\n (4.4\u20134.2%) had not changed significantly (\n P<\/jats:italic>\n \u2009>\u20090.05). These common species were consistent with China Antimicrobial Surveillance Network reported in 2018 (2018 CHINET report), but their composition ratios were different. In addition, among bacteremia, the proportion of multidrug-resistant bacteria gradually increased from 52.9 to 68.4% (time trend\n P<\/jats:italic>\n \u2009<\u20090.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The proportion and species distribution of BSI were dynamically changing along certain trends.
