Hospital-acquired infections, also known as healthcare-associated infections (HAI), are nosocomially acquired infections that are typically not present or might be incubating at the time of admission. assessed CLABSI surveillance metrics by comparing clinician assessment of infection with NHSN definitions. CLABSI is the term used by the US Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) 9 (see NHSN CLABSI information). Central Line-Associated Bloodstream Infection (CLABSI) Prevention Guideline Evidence-Based Guideline Definition: According to the Centers for Disease and Control, a central line-associated bloodstream infection (CLABSI) is a primary bloodstream infection in a person with a central venous catheter in the 48 hours preceding the infection that ©2021 CHA Infection Surveillance •Know the NHSN definitions •Consistently apply the definitions •Failure to do so = breach of NHSN Rules of Behavior o Decreases usefulness of national and state comparative data o Allows unfair comparisons between facilities •Concerns about the definitions should be sent to NHSN for clarification. 1 NHSN: The National Healthcare Safety Network, of the Centers for Disease Control and Prevention (CDC), is the nation’s most widely used health care-associated infection tracking system.Since 2009, infection data has been reported to the NHSN to track the national progress of the reduction of HAIs. The local team retrospectively applied the revised 2013 NHSN CLABSI definition to all study cases to minimize bias due to changes in the CLABSI definitions during the study years. The study consisted of 123 patient cases across six New Mexico hospitals and found that specificity, PPV, and NPV were quite high, yet sensitivity was moderate, suggesting that CLABSI was underreported. We reviewed the accuracy of NHSN definitions in a large healthcare system. The National Healthcare Surveillance Network (NHSN), in partnership with the Centers for Disease Control (CDC), have established definitions that are used to classify CLABSI. NHSN operative procedure categories is not considered an NHSN SSI, although the infection may be investigated as a HAI – Denomination #9 • More than one operative procedure through same incision/surgical space within 24 hours – “…or into the same surgical space…” • Additions: – Added acceptable documentation The lack of CDC/NHSN definitions for certain secondary sites of infections or problems in the definitions may lead to over-labeling CLABSIs. In addition, acute-care NHSN CLABSI criteria 2 may not apply to home infusion therapy. These infections are usually acquired after hospitalization and manifest 48 hours after admission t … 9 An adapted version of the NHSN primary bloodstream infection case report form 22 was used to classify CLABSI cases as MBI or non-MBI. NHSN definitions must be met to attribute a secondary BSI (SBSI), or bacteremia is defaulted to CLABSI if a central line is present. NHSN definitions must be met to attribute a secondary BSI (SBSI), or bacteremia is defaulted to CLABSI if a central line is present. Although definitions for CLABSI in home infusion therapy have existed since 2008, 1 these definitions have not been widely accepted among home infusion professionals.
