Project description and aims

Project main description

There is now little doubt that the inappropriate use of antibiotics (abx) contributes to the emergence of resistance and that improving abx use is necessary for the containment of resistance. Many interventions have been trialled in an attempt to improve abx use (e.g. education, audit and feedback, computerised decision support). In this study, we evaluated the effectiveness of redesigning computerised decision support to improve abx prescribing.


In this study, we aimed to determine whether the redesign of computerised decision support embedded in a hospital electronic prescribing system results in more accurate selection of antibiotic indications and more compliant and appropriate antibiotic prescribing.

Design and method

An audit of over 1000 antibiotic prescriptions was undertaken, in combination with interviews with prescribers.
