Questions and Answers
A Laboratory Confirmed Bloodstream Infection (LCBI) that is not secondary to an infection at another body site is also known as _______________________?
Primary Blood Stream Infection
Define continuous and intermittent infusion and give some examples of both.
The administration of any solution through the lumen of a catheter into a blood vessel. Continuous infusion (e.g., nutritional fluids or medications) and intermittent infusion (e.g., IV flush, IV antimicrobial administration, blood transfusion, or hemodialysis treatment).
What actions would meet the definition of 'access' to the bloodstream?
Line placement, use of any central line for infusion or withdrawal of blood, and hemodynamic monitoring.

If an ICU patient's central line is only accessed by dialysis staff during dialysis treatment, it does not have to be included in CLABSI surveillance.

No additional elements are needed to meet LCBI 1 criterion; therefore, the LCBI 1 date of event will always be the collection date of the first positive blood specimen.

Study Notes
Bloodstream Infections Overview
- Primary Blood Stream Infection (PBSI): A Laboratory Confirmed Bloodstream Infection (LCBI) that is not secondary to an infection from another body site.
Infusion Types
- Continuous Infusion: Involves the steady administration of solutions (e.g., nutritional fluids, medications).
- Intermittent Infusion: Involves periodic administration (e.g., IV flushes, antimicrobial therapy, blood transfusions).
Access to Bloodstream
- Access Definition: Activities shouldered during inpatient admission that include line placement, infusion or withdrawal using any central line, and hemodynamic monitoring.
Central Lines
- Introducer Catheter: May be classified as a central line depending on tip location and use.
LCBI Classification
- LCBI 1 vs. LCBI 2: LCBI 2 requires at least one sign or symptom (e.g., fever, chills, hypotension).
Surveillance for CLABSI
- De-accessing Central Lines: Does not exclude patients from CLABSI surveillance; they remain included in device day counts.
Non-Culture Tests (NCT)
- NCT Definition: Refers to diagnostic tests not based on cultures, such as T2 Magnetic Resonance and the Karius Test.
Karius Test
- Karius Test®: A liquid biopsy for infectious diseases aiding fast and accurate diagnosis, facilitating quicker patient recovery.
LCBI Surveillance Determination
- Blood Culture Priority: Prioritize results from blood cultures over NCT results if both are obtained within a specific timeframe. NCT results can be used if no blood culture is collected.
Central Line Day Count
- Day of First Access: Initiated upon admission to an inpatient location if a central line is already in use.
ICU Patient Surveillance
- Dialysis Staff Access: Patients in ICU with central lines accessed solely by dialysis staff still require inclusion in CLABSI surveillance.
MBI-LCBI Determination
- Date of Event (DOE): Reflects when prerequisite LCBI criteria are met; abnormal lab values do not signal infection.
LCBI 1 Criteria
- LCBI 1 Determination: No additional signs or symptoms are required; the DOE coincides with the collection date of the first positive blood specimen.
