OCT-BIO-CVC

Details and patient eligibility

About

29.3% of bacteremias in intensive care units (ICU) are linked to vascular devices, with a significant proportion related to central venous catheters, and an influence on both morbility and mortality.

It is now accepted that microbiological biofilm plays a key role on both bacterial and fungal development on inner surface of vascular devices but there is yet a lack of clinical relevant data documenting a causal relation between biofilm formation and bacteremias.

We assume that a more precise characterization of central venous catheter-deposited biofilm could help us better understand invasive medical device-related healthcare infections in critically ill patients.
