Background Antimicrobial stewardship (AMS) programs aim to secure the rational prescription of antibiotics through implementing department- or hospital-level activities. Infectious disease (ID) specialists improve the quality of care and outcomes in infection patients predominantly by individual consultations and patient-level interventions. While hospital AMS programs are established to various extents in Germany, ID specialist services are rarely available in this country. In the ID ROLL OUT study, we will implement and evaluate hospital-level AMS tools with and without ID specialist services in secondary and tertiary care hospitals. We aim to identify means to comprehensively and sustainably improve the quality of care of patients with infectious diseases. Methods This project is a clustered, two-armed intervention study, which will be conducted in ten secondary and tertiary (non-university) care hospitals in Germany. The intervention groups are stratified by key characteristics of the hospitals. We will compare two interventional strategies: implementation of AMS teams and implementation of AMS teams combined with the activities of ID specialists (AMS + IDS). Planned Outcomes The primary outcome is the quality of care as measured in changes in a Staphylococcus aureus bacteremia (SAB) score (as an indicator of difficult-to-treat infections) and a community-acquired pneumonia (CAP) score (as an indicator of common infections) compared to a baseline pre-interventional period. Our secondary outcomes comprise patient- and hospital-level outcomes, such as the quality and frequency of antibiotic treatment, in-hospital mortality, duration of hospitalization, and C. difficile incidence (associated diarrhea episodes). The study may provide urgently needed key information for the aspired advancement of ID care in Germany. Trial Registration DRKS00023710 (registered on 9th April 2021).
