BackgroundThe Johns Hopkins Children's Medical and Surgery Center developed a Web-based Antimicrobial Stewardship Program (ASP) in 2005. The present study aimed to assess longitudinal antimicrobial request and approval patterns for this ASP.MethodsWe analyzed a total of 16,229 antimicrobial requests for 3,542 patients between June 1, 2005, and June 30, 2009. Antimicrobial approval was the outcome of interest. We assessed gaming by studying trends in automatically approved requests. Nonparametric tests for trend were performed to detect changes in approval patterns. Multiple logistic regression was used to identify factors associated with approval.ResultsThe vast majority (91.3%) of antimicrobial requests were approved, with an increase of 6.1% over time (P < .01). Renewal requests were more likely than primary requests (adjusted odds ratio [aOR], 1.72; 95% confidence interval [CI], 1.45-2.04) to be approved. Antiviral requests had higher odds of approval than antibiotic requests (aOR, 1.27; 95% CI, 1.04-1.56). Compared with requests by medical services, requests by surgical services had lower odds of approval (aOR, 0.70; 95% CI, 0.59-0.83), whereas pediatric intensive care requests had higher odds of approval (aOR, 1.18; 95% CI, 1.00-1.40). The number of auto-approved requests remained consistent.ConclusionsThe Web-based ASP allows management of a large number of antimicrobial requests, without apparent gaming. Observed differences in approval patterns based on patient, requestor, and antimicrobial factors may inform the development of ASPs and evaluation of provider education and training.
