摘要 目的探讨血培养阳性报警时间(Time-to-positivity,TTP)对金黄色葡萄球菌(SAU)血流感染患者预后的诊断价值。方法回顾性分析2014年1月至2018年6月本院收治的血培养结果为SAU感染的126例患者的临床资料,分析126例患者的TTP值,根据TTP值,将126例患者分为低TTP组(TTP≤21 h,n=64例)和高TTP组(TTP>21 h,n=62例),比较低TTP组与高TTP组耐甲氧西林金黄色葡萄球菌(Methicillin-resistant Staphylococcus aureus,MRSA)感染发生率及迁徙性感染灶发生率。结果低TTP组及高TTP组MRSA感染发生率分别为31.25%(20/64)、77.42%(48/62),低TTP组及高TTP组迁徙性感染灶发生率分别为59.38%(38/64)、32.26%(20/62),两组比较,均有P<0.05。结论TTP延长提示SAU感染患者发生MRSA感染的风险大大增加,TTP缩短提示迁徙性感染的风险大大增加,在临床中可根据TTP的时间判断金黄色葡萄球菌感染患者的预后。
