Assessing the impact of institution-specific guidelines for antimicrobials on doctors' prescribing behavior at a German tertiary-care center and the additional benefits of providing a mobile application.

ISGs are used regularly and appear to have a relevant impact on clinicians' prescribing habits. A mobile app may be the most effective way to provide ISGs, although multiple platforms seem to add value. While the majority of participants reported perceived effects on their prescribing behavior, this study does not allow any conclusions to be drawn about the extent of the effects of ISGs on antibiotic use and patient outcomes.
