[Comment] Vascular catheter infections: time to get technical

Catheter-related bloodstream infections were once viewed as an inescapable consequence of providing care to critically ill patients. It was not until the beginning of the 21st century that a conceptual model identified both technical and socioadaptive strategies to prevent this outcome.1 Key among technical factors were processes such as skin disinfection with chlorhexidine and use of large drapes at the time of insertion to prevent catheter contamination. Conversely, socioadaptive factors were focused on behavioural aspects such as adhering to proper hand hygiene, nurse-led halts if parts of sterile insertion were not followed, and targeting of unit-specific culture to increase compliance.
