Evaluation of an AI-Assisted Tool for CLABSI Surveillance at VA Medical Centers (VA-AI-CLABSI)

2 november 2026 bijgewerkt door: Daniel Morgan, University of Maryland, Baltimore

VA National AI Initiative (NAII) Evaluation of an AI-Assisted CLABSI Surveillance Tool: A Prospective Cluster-Randomized Trial

Infection prevention and control programs at US hospitals perform surveillance to detect and publicly report hospital-onset central line-associated bloodstream infections (CLABSI) using standards set by CDC's National Healthcare Safety Network (NHSN). Because this process requires time-consuming review of the medical record by dedicated infection preventionists, VA has developed a generative artificial intelligence (AI) tool that applies the NHSN CLABSI standard to clinical data from the medical record. In this quality improvement initiative, we will evaluate the tool as it is implemented operationally across a cohort of VA medical centers in 3 randomized waves. The purpose of this evaluation is (1) to determine whether the tool reduces the time required for CLABSI surveillance, (2) to assess the objectivity and trustworthiness of the tool from the perspective of infection preventionists, and (3) to detect patient safety events.

Beschrijving

Infection preventionists will participate in this study if their VA medical center is eligible based on the inclusion and exclusion criteria below. At participating sites, all positive blood culture events reviewed as potential central line-associated bloodstream infections (CLABSI) during the study period will be included in the analysis.

Inclusion Criteria:

  1. VA medical center that provides short- or long-term acute care
  2. CLABSI surveillance is performed by a local infection prevention team who agree to complete all study assessments

Exclusion Criteria:

1. VA medical center planned for conversion to the Cerner electronic health record within the anticipated study period

Experimenteel: Post-implementation of an AI for CLABSI surveillance

Infection preventionists (reviewers) at participating VA medical centers will use the generative artificial intelligence (AI) tool while reviewing cases of bacteremia to adjudicate the presence of a central line-associated bloodstream infection (CLABSI). The tool operationalizes the CDC's National Healthcare Safety Network definition of CLABSI as discrete steps. Reviewers will be allowed to flexibly implement the tool within their workflow, will not be restricted from performing independent review of the medical record to clarify tool output when necessary, and will retain final authority regarding all CLABSI determinations for event reporting.

The intervention involves implementation of a generative artificial intelligence (AI) tool that operationalizes the CDC National Healthcare Safety Network definition for central line-associated bloodstream infections (CLABSI) to support CLABSI surveillance. The tool reviews the medical record to confirm the presence and duration of a central line, identify competing or secondary sources of infection, exclude commensal organisms and bloodstream infections due to mucosal barrier injury, and provide supporting quotations from the medical record.

Geen tussenkomst: Standard CLABSI surveillance

Infection preventionists at participating VA medical centers will use their pre-intervention approach to surveillance for central line-associated bloodstream infections (CLABSI), which involves manual review of the medical record and reporting per the CDC National Healthcare Safety Network CLABSI definition.
