A Nationwide Survey of Antimicrobial Stewardship Practices

Abstract

ObjectiveThe goal of this study was to characterize hospital antimicrobial stewardship practices nationwide and to identify factors associated with the presence of these programs. MethodsThe first web-based survey was sent in 2009 to members of the Yankee Alliance and the Premier Healthcare Alliance, nationwide organizations of health-care providers. The second survey, a slightly modified version of the first, was sent in 2010 to a commercially purchased list of hospital pharmacy director e-mail addresses. ResultsA total of 406 responses were received from ~5890 providers targeted, for an overall response rate of ~7%. More than one half (206 of 406) of the respondents reported having what they considered to be a formal antimicrobial stewardship program (ASP). Among all respondents regardless of presence or absence of an ASP, 96.4% (351 of 364) were using some form of antimicrobial stewardship technique. Of those respondents working in hospitals without an ASP, 63.3% (114 of 180) had considered implementing one. After controlling for all significant variables, those that remained which were significantly associated with having an ASP were survey (Premier vs commercial), having an infectious disease consultation service, and having an infectious disease pharmacist. ConclusionsIn this survey of 406 respondents from across the country, we found that just more than one half of hospitals had what they considered to be formal ASPs; however, the vast majority were using stewardship techniques to optimize the use of antibiotics. Common barriers to implementation of ASPs included staffing constraints and insufficient funding.
