The role of initial specimen diversion devices (ISDDs) in preventing contamination of central venous catheter (CVC) blood cultures is undefined. A model to simulate CVC colonization and contamination compared standard cultures with ISDD technique. ISDD detected 100% of colonized CVCs while decreasing false-positive cultures from 36% to 16%.
初始样本分流装置（ISDDs）在预防中心静脉导管（CVC）血培养污染方面的作用尚不明确。一个模拟CVC定植和污染的模型将标准培养与ISDD技术进行了比较。ISDD检测出了100%定植的CVC，同时将假阳性培养从36%降至16%。
