The optimal way for antimicrobial stewardship programs (ASPs) to interact with existing infectious disease physician (IDP) services within the same institution is unknown. In our institution, IDPs and our prospective audit and feedback ASP operate independently, with occasionally differing recommendations offered for the same inpatient. We performed a retrospective audit on inpatients that had been reviewed by both IDPs and ASP within a 7-day period, focusing on cases where different therapy-modifying recommendations had been offered. We analyzed the outcomes in inpatients where the ASP recommendations were accepted and compared these with the inpatients where the IDP recommendations were accepted instead. Outcomes assessed were 30-day mortality post-ASP review, unplanned re-admission within 30 days post-discharge from hospital, and clinical deterioration at 7 days post-ASP review.
