Utilization of the Sharing Antimicrobial Reports for Pediatric Stewardship (SHARPS) Collaborative electronic mailing list (listserv) by healthcare professionals.

Optimizing pediatric antimicrobial stewardship is challenging. In this retrospective study, we evaluated 515 original e-mails to 482 members of the Sharing Antimicrobial Reports for Pediatric Stewardship (SHARPS) Collaborative electronic mailing list (idlistserv@kids.wustl.edu). The plurality of threads discussed clinical practice guidelines, and pharmacists were most likely to initiate and respond. Representation was geographically diverse within and outside the United States.
