We retrospectively compared the clinical characteristics of hospital-acquired (HA) vs non-hospital-acquired (nHA) complex isolates in a large health care system in St. Louis, Missouri, from 2007 to 2017. More than 60% of the total isolates were nHA; they were predominantly from nonrespiratory sources and exhibited ~40% carbapenem resistance rates and stably persisted, though HA occurrence waned.
我们回顾性比较了2007年至2017年密苏里州圣路易斯市一个大型医疗系统中医院获得性(HA)与非医院获得性(nHA)复杂分离株的临床特征。总分离株中超过60%为nHA;它们主要来自非呼吸道来源,碳青霉烯耐药率约为40%,且稳定存在,尽管HA的发生率有所下降。
