- Positive predictive value of a positive blood culture was only 53%.
- A 50% reduction in false positives would save approximately twice as much as a 50% reduction in false negatives.
- Although only 6% of the blood cultures represented contaminants, their associated cost was more than twice that associated with the 87% that were true negatives.
