摘要

Purpose

Non-university hospitals are the major provider of inpatient care in Germany, but the extent of antimicrobial stewardship (AMS) activities in this sector is not well known. We aimed to evaluate the implementation of AMS in ten non-university hospitals in Germany.

Methods

A pre-existing French score covering key AMS categories (structures, resources and actions) was adapted to the German AMS guidelines and named AMS-GER score. The score was assessed before, during and after the implementation of a bundle of AMS measures. The bundle was implemented as part of the ID ROLL OUT study – a multicentre pre-post interventional study in non-university hospitals in Germany.

Results

At baseline, the median AMS-GER score was 37% (range 20–60%), indicating poor implementation in 9 out of 10 hospitals. The intervention resulted in a significant score improvement to 76% (range: 62–86%, p < 0.001). At the one-year follow-up after the intervention, the AMS-GER score had decreased in all hospitals (median: -13 percentage points (range: 48–80%, p = 0.015)). Hospitals with ongoing full-time AMS/ID staffing (4/10 hospitals) experienced a smaller decrease ( – 13 percentage points) than those without ( – 32 percentage points in 6/10 hospitals).

Conclusion

Routine integration of AMS in a large sample of non-university hospitals in Germany is low but can be significantly improved by targeted interventions. The decline in the AMS-GER score in the follow-up phase—particularly in hospitals lacking ongoing AMS/ID staffing—highlights the need for sustained staffing and systematic benchmarking. In this context, the AMS-GER score offers a structured tool for AMS monitoring in German hospitals.
