An exception-reporting approach for wound swab culture: effect on post-report antibiotic initiation.

Wound swab culture is a high-volume test performed in clinical microbiology laboratories. In this analysis, we have shown that an alternative approach to reporting positive wound swab cultures has resulted in a large reduction in post-report antibiotic initiation, suggesting that the current standard method of reporting generates considerable unnecessary antibiotic use. If these findings are replicated elsewhere, wider adoption of this reporting would represent an opportunity for many clinical microbiology laboratories to have a significant impact on community antimicrobial stewardship.
