title: Use of MALDI-TOF to detect colonized vascular catheter tips after 6 and 12h of incubation.
abstract: We analyzed by MALDI-TOF MS 80 catheter tips after 6h and 12h of incubation and the sensitivity of each incubation period for the identification of colonization and C-RBSI was, respectively, 9.5%-NA and 42.9%-28.6%. Despite MALDI-TOF MS cannot be used to predict catheter colonization, it may rule out C-RBSI.
