Respiratory infections are still among the most common new diagnoses in primary care. The most frequent reason for encounter is acute cough. General practitioners have to make antibiotic prescribing decisions in a context of diagnostic uncertainty, patient preferences and antimicrobial resistance. ⋯ A GRACE randomized controlled trial (RCT) of the effect of antibiotics for acute cough has recruited more patients than all RCTs combined in the current Cochrane Review and will have the power to identify subgroups of patients who will (not) benefit from amoxicillin. Another multi-country GRACE RCT assessing the effect on antibiotic prescribing of largely web-based versions of successful interventions including a C-reactive protein point-of-care test, a communication skill training and an interactive patient booklet is awaited. Given potential long-term cost-effectiveness, the GRACE suite of observational and interventional studies are enhancing the evidence base for reducing diagnostic uncertainty and managing patient expectations in a patient-centred way to achieve greater evidence-based antibiotic prescribing that is likely to help containing antimicrobial resistance.
