Reducing Overuse of Antibiotics with Decision Support

The ED-CDS intervention is designed as a discrete decision support aid to influence initial antibiotic decision-making in the ED. This intervention will feature a clinician-facing LRTI dashboard for end-users that assimilates relevant clinical data (e.g., vital signs, select diagnostic tests, links to reference information) and offers tailored suggestions for antibiotic initiation, related diagnostic testing, and in those receiving antibiotics, preferred options and alternatives for antibiotic choice, route, dose, and duration.

The CDS-Tr intervention is designed as a longitudinal decision support aid to influence initial and ongoing (i.e., continuation, discontinuation, escalation, or de-escalation) antibiotic decision-making in the hospital setting. This intervention will also feature the LRTI dashboard along with additional tailored suggestions and recommendations for antibiotic decision-making upon hospital admission, and for those receiving antibiotics, at the time of discharge. Additionally, CDS-Tr will be active at the time of any service transition (i.e., hospital to intensive care or vice versa) and at pre-specified time points (e.g., approximately 48 hours and 120 hours following ED triage for encounters remaining in the hospital).
