Why we prescribe antibiotics for too long in the hospital setting: a systematic scoping review

Abstract

Background: In daily hospital practice, antibiotic therapy is commonly prescribed for longer than recommended in guidelines. Understanding the key drivers of prescribing behaviour is crucial to generate meaningful interventions to bridge this evidence-to-practice gap.

Objectives: To identify behavioural determinants that might prevent or enable improvements in duration of antibiotic therapy in daily practice.

Methods: We systematically searched PubMed, Embase, PsycINFO and Web of Science for relevant studies that were published between January 2000 and August 2021. All qualitative, quantitative and mixed-method studies in adults in a hospital setting that reported determinants of antibiotic therapy duration were included.

Results: Twenty-two papers were included in this review. A first set of studies provided 82 behavioural determinants that shape how health professionals make decisions about duration; most of these were related to individual health professionals' knowledge, skills and cognitions, and to professionals' interactions. A second set of studies provided 17 determinants that point to differences in duration regarding various pathogens, diseases, or patient, professional or hospital department characteristics, but do not explain why or how these differences occur.

Conclusions: Limited literature is available describing a wide range of determinants that influence duration of antibiotic therapy in daily practice. This review provides a stepping stone for the development of stewardship interventions to optimize antibiotic therapy duration, but more research is warranted. Stewardship teams must develop complex improvement interventions to address the wide variety of behavioural determinants, adapted to the specific pathogen, disease, patient, professional and/or hospital department involved.
