Central Line Associated Primary Bloodstream Infection (CLI)

What is CLI


A central venous catheter (or “line”) is fed through a vein and provides access to major blood vessels (e.g. aorta, pulmonary artery). A typical intravenous line, or IV, is not considered a central line. These lines are inserted through artificial openings in the skin, which decreases the ability of the body to keep out bacteria. A central line primary bloodstream infection (CLI) occurs when bacteria get into the line and spread to the bloodstream causing infection.

What does this indicator show?

This indicator shows the rate of newly diagnosed Central Line-Associated Primary Bloodstream Infection (CLI) cases in the Intensive Care Unit (ICU) after at least 48 hours of being placed on a central line.

How is CLI calculated?

Total number of newly diagnosed CLI cases for ICU patients 18 years and older after at least 48 hours of being placed on a central line x 1000
Total number of central line days (days spent on a central line) for ICU patients 18 years and older

Why does TBRHSC track CLI?

Measuring, monitoring, and reporting CLI rates is one part of a comprehensive Infection Prevention and Control (IPAC) program. The information gathered can assist hospitals with evaluating the effectiveness of their IPAC interventions and make further improvements based on this information.


The Ontario Ministry of Health and Long-Term Care introduced public reporting as part of a comprehensive plan to improve transparency and accountability related to hospital care. CLI data is entered into CCIS (Critical Care Information System) and cases are reported to the public on a quarterly basis.
