Objective: Develop a clinical decision support tool comprised of an electronic medical record alert and antimicrobial stewardship navigator to facilitate antimicrobial stewardship.
Design: We analyzed alerts targeting antimicrobial de-escalation to assess the effectiveness of the navigator as a stewardship tool. The alert provides antimicrobial recommendations, then directs providers to the navigator, which includes order management, relevant patient information, evidence-based clinical information, and bidirectional communication capability.
Setting: Academic, tertiary care medical center with an electronic medical record.
Intervention: Alerts containing stewardship recommendations and immediate access to the navigator were created.
Results: Antibiotic use and response data were collected 1 day before stewardship recommendation via the best practice alert (BPA) tool and 1 day after the BPA tool response. A total of 1,285 stewardship BPAs were created. Two hundred and forty-four (18.9%) of the BPAs were created and acted upon within 72 hours for the purpose of de-escalation: 169 (69%) were accepted, 30 (12%) were accepted with modification, and 45 (18%) were rejected. Statistically significant decreases in total antibiotic use as well as in use of broad-spectrum (anti-methicillin-resistant Staphylococcus aureus and anti-pseudomonal) agents occurred when accepted recommendations were compared with rejected recommendations.
Conclusions: We describe the successful development of a clinical decision support tool to perform prospective audit and feedback comprised of an alert and navigator system featuring evidence-based recommendations and clinical and educational information. We demonstrate that this tool improves antibiotic use through our example of de-escalation.
