BrighT STAR LIBRA: Leveraging Implementation Science for Blood Culture Reduction Approaches

This intervention consists of a checklist to guide blood culture decisions, that a clinician in a site randomized to Arm A will be asked to consult and complete prior to ordering or not ordering a blood culture; as the relevant clinical scenario occurs. Meaning, if a clinician in Arm A is faced with a scenario in which it is customary or usual care to consider a blood culture, the clinician will be asked to first review this checklist. The checklist is not a binding or absolute process - the clinician should use both the checklist and typical clinical judgment to decide if the blood culture test is needed or not. The checklist is based on prototypes used in the completed parent study, BrighT STAR and the earlier preliminary studies at Johns Hopkins.

This intervention consists of targeted messaging and education that the primary study team will create and ask the Arm B sites to deliver to the PICU clinicians, which focuses on the importance of diagnostic stewardship and the current evidence for the benefit/low risk nature of the stewardship program to date.
