Impact of a strategy based on unique blood culture sampling on contamination rate and detection of bloodstream infections in critically ill patients
Authors' conclusion
In ICU patients, a strategy based on UBC reduces the contamination rate of cultures without affecting their yield.
Study context
- Population
- Critically ill ICU patients undergoing blood culture sampling17,466 BC collected
- Participants
- 4,491 patients
- Comparison
- Unique blood culture strategy vs multi-sampling strategy
- Outcome
- Rate of BC contamination (BC contaminations (BCC)) and of bloodstream infection (bloodstream infections (BSI)) per patient
Methodological detailsmulti-faceted program, education and feedback, 4-month washout period with staff education and training between periods
- Multi-faceted program
- Education and feedback
- 4-month washout period with staff education and training between periods
