The whole is greater than the sum of its parts: effect of implementing an ABS consultation service in the ABS program on antibiotic consumption at a tertiary military hospital.

Abstract

Background: Infections with multidrug resistant (MDR) pathogens represent an enormous challenge for the healthcare system. By implementing the principles of Antibiotic Stewardship (ABS), the rational use of antibiotics is promoted to counteract the increasing development of resistance on the one hand and to ensure adequate treatment for patients on the other.

Methods: An interdisciplinary ABS team has therefore been set up at the Bundeswehr Central Hospital and is available to medical staff every working day as part of a consultation and ward-rounds service. The work of the ABS team primarily serves to advise on the treatment, diagnosis and prevention of infectious diseases. It also intends to provide knowledge during the training of young medical officers in order to promote the rational use of antibiotics even outside the Bundeswehr Central Hospital.

Results: Since the implementation of the consultation and ward-rounds service, antibiotic consumption at the Bundeswehr Central Hospital has been reduced by 25%. In this context, the halving of carbapenem consumption is particularly noteworthy. Furthermore, the rising number of consultation requests shows an increasing need for the service and acts as a marker for ABS awareness.

Conclusion: The reduction in antibiotic consumption is not solely due to the mentioned service, but is also the result of interdisciplinary ABS measures.
