Central line–associated bloodstream infection (CLABSI) remains a major healthcare-associated infection in intensive care units and is associated with increased mortality, prolonged hospitalization, and higher medical costs. Traditional prevention strategies, represented by Care Bundle 1.0, have demonstrated substantial effectiveness in reducing infection rates using standardized aseptic insertion techniques. However, in high-acuity settings, CLABSI incidences often reach a plateau despite high compliance, suggesting the presence of residual risks not addressed by insertion-focused measures alone. Care Bundle 2.0 has emerged as an advanced framework that expands beyond procedural compliance to include the maintenance of quality, continuous monitoring, and organizational culture. In addition, catheter exposure time and device selection have been increasingly recognized as critical determinants of infection risk. The prolonged use of conventional central venous catheters (CVCs) is strongly associated with biofilm formation and persistent bloodstream infections. Peripherally inserted central catheters (PICCs) may be strategic alternatives for clinically stable patients who require long-term intravenous therapy. Timely transition from CVC to PICC can reduce high-risk catheter exposure and improve infection control outcomes. This review summarizes the evolution of CLABSI prevention strategies and highlights the role of device optimization within the Care Bundle 2.0 framework, emphasizing the shift from checklist-based compliance to dynamic risk management. |
