Discord among performance measures for central line-associated bloodstream infection.

Background: Central line-associated bloodstream infection (CLABSI) is a national target for mandatory reporting and a Centers for Medicare and Medicaid Services target for value-based purchasing. Differences in chart review versus claims-based metrics used by national agencies and groups raise concerns about the validity of these measures.

Objective: Evaluate consistency and reasons for discordance among chart review and claims-based CLABSI events.
