Central Line-Associated Bloodstream Infection Prevention

Central line-associated bloodstream infections (CLABSIs) are serious and costly healthcare-associated infections that are largely preventable through evidence-based practices. CLABSI prevention has been a major quality improvement success story, with dramatic reductions achieved through bundle implementation. CPHQ candidates should understand the prevention strategies, measurement methods, and quality implications.

The Central Line Bundle

The central line insertion bundle, popularized by the Keystone ICU Project in Michigan, includes five evidence-based practices: hand hygiene before insertion, maximal sterile barrier precautions (cap, mask, sterile gown, sterile gloves, and large sterile drape), chlorhexidine skin antisepsis, optimal catheter site selection (avoiding the femoral vein when possible), and daily review of line necessity with prompt removal of unnecessary lines.

Maintenance Practices

Prevention extends beyond insertion to ongoing catheter maintenance. Key maintenance practices include performing hand hygiene before accessing the line, disinfecting catheter hubs and injection ports before each access ("scrub the hub"), changing dressings using aseptic technique, performing daily assessments of line necessity, and using chlorhexidine-impregnated dressings for central venous catheters.

Surveillance and Definitions

CLABSI surveillance follows NHSN definitions. A CLABSI is a laboratory-confirmed bloodstream infection where the central line was in place for more than two calendar days on the date of the event and the line was in place on the date of the event or the day before. Understanding the surveillance definition is important for accurate case identification and consistent reporting.

The Keystone Project

The Michigan Keystone ICU Project demonstrated that comprehensive implementation of evidence-based practices could virtually eliminate CLABSIs. The project combined the insertion bundle with a comprehensive unit-based safety program that addressed safety culture, teamwork, and accountability. Sustained results showed that near-zero CLABSI rates are achievable and maintainable.

Reporting and Accountability

CLABSI rates are publicly reported through CMS Hospital Compare. Performance affects payment through the Hospital-Acquired Condition Reduction Program. Rates are expressed as standardized infection ratios comparing observed to expected infections. Quality professionals should monitor CLABSI data, conduct root cause analysis when infections occur, and lead improvement efforts to maintain prevention bundle compliance.
