Here are some of the findings from the study, which was published in the October issue of the American Journal for Infection Control (AJIC):
- 100% of the infection control departments reported inclusion or exclusion of central line types inconsistent with the CDC CA-BSI definition
- 50% calculated line-days inconsistently
- Only 50% used a strict, written policy for classifying BSIs
- Though more than 80% of the hospitals surveyed reported having a formal, written policy about obtaining blood cultures, less than 80% of these address obtaining samples from patients with central venous lines, and any such policies are reportedly followed less than half of the time
- Substantial variation exists in blood culturing practices, such as temperature thresholds, preemptive antipyretics, and blood sampling (volume, number, sites, frequency).
