The emergence of antibiotic resistance is the result of natural selection: Prescribing more antibiotics causes more selective pressure, which drives greater resistance. Thus, to decrease resistance, we need to prescribe fewer antibiotics.In 2008, one of us (L.B.R.) posited that of the different ways the medical community could reduce the amount of antibiotic treatment prescribed, the one that seemed safest and most achievable was to treat infections only for as long as necessary to achieve optimal cure rates (1).

  • Abbreviated β-lactam courses (typically 3-5 days) can achieve comparable cure rates to longer regimens while reducing microbiome disruption and minimizing adverse effects.

    “Evidence from controlled trials and real-world data consistently demonstrates that abbreviated β-lactam courses (typically 3-5 days) can achieve comparable cure rates to longer regimens while reducing microbiome disruption and minimizing adverse effects [16-18].”

    From Clinical Outcomes and Real-World Effectiveness of Amoxicillin-Clavulanic Acid Across Indian Healthcare Settings: A Retrospective Multicenter Study (2026) · cites this paper as [16]

    The main text (page not supplied) reports that 3–5-day antibiotic courses were at least as effective as 7–14-day courses for community-acquired pneumonia, and that longer courses caused more adverse effects. It does not establish that the finding applies specifically to β-lactams or that shorter courses reduce microbiome disruption; the 3–5-day comparison is specific to community-acquired pneumonia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
