Honey, I Shrunk the Antibiotic Therapy

Can the Future of ID Escape the Inertial Dogma of Its Past? The Exemplars of Shorter Is Better and Oral Is the New IV

Like all fields of medicine, Infectious Diseases is rife with dogma that underpins much clinical practice. In this study, we discuss 2 specific examples of historical practice that have been overturned recently by numerous prospective studies: traditional durations of antimicrobial therapy and the necessity of intravenous (IV)-only therapy for specific infectious syndromes. These dogmas are based on uncontrolled case series from >50 years ago, amplified by the opinions of eminent experts. In contrast, more than 120 modern, randomized controlled trials have established that shorter durations of therapy are equally effective for many infections. Furthermore, 21 concordant randomized controlled trials have demonstrated that oral antibiotic therapy is at least as effective as IV-only therapy for osteomyelitis, bacteremia, and endocarditis. Nevertheless, practitioners in many clinical settings remain refractory to adopting these changes. It is time for Infectious Diseases to move beyond its history of eminent opinion-based medicine and truly into the era of evidenced-based medicine.

[Practice-guided Presentation of the German S3 Guideline "Strategies to Warrant Rational In-hospital Use of Antibiotics"]

The current S3 guideline entitled "Strategies to warrant rational in-hospital use of antibiotics" summarizes evidence-based antibiotic stewardship (ABS) measures that aim to improve clinical outcomes and prevent development and spread of microbial resistance in German hospitals. Most important prerequisite for efficiency and safety of ABS programs is sufficient staffing capacity as well as reliably operating surveillance of (i) pathogens, (ii) antimicrobial resistance and (iii) consumption of antimicrobials. ABS teams require authorization by hospital institutions as units exclusively responsible for antimicrobial audits and implementation of anti-infective interventions. Clinicians should be regularly granted access to in-hospital training programs delivered by ABS experts. Finally yet importantly, the current S3 guideline also highlights future goals, e.g., the structured involvement for nurses in ABS-guided infection management or the promotion of ABS programs in the outpatient sector and in veterinary medicine.
