Use of diagnostic and antimicrobial stewardship practices to improve Clostridioides difficile testing among SHEA Research Network hospitals.

We surveyed acute-care hospitals on strategies to reduce inappropriate C. difficile testing and treatment of colonized patients. Decision support during C. difficile test ordering was common, but "hard stops" to prevent placement of inappropriate orders and active intervention of antimicrobial stewardship programs on positive C. difficile test reports were infrequent.
