[Acute Cough in Adult Patients]

Acute cough (< 8 weeks) is a frequent complaint in family practice consultations. The most common cause are respiratory infections. The Guideline "Acute and chronic cough" of the German College of General Practitioners and Family Physicians (DEGAM) was updated in 2021 and contains recommendations for an evidence-based approach for the management of acute cough in primary care.

The guideline has been updated in accordance with the findings of a systematic search of the literature for international guidelines and systematic reviews. All recommendations were developed by an interdisciplinary guideline committee and agreed by formal consensus.

History-taking, exclusion of red flags and a physical examination are the basis of diagnostic evaluation. If an acute, uncomplicated bronchitis is likely, no laboratory tests, sputum diagnostics, or chest x-rays should be performed, and antibiotics should not be administered. Evidence based strategies to avoid antibiotic therapy (delayed prescribing, shared decision making, point-of-care-tests) can be used. There is inadequate evidence for the efficacy of antitussive or expectorant drugs against acute cough. The state of the evidence for phytotherapeutic agents is heterogeneous; clinical importance is minimal. COVID-19 should currently be considered in cases of acute respiratory symptoms. If specific symptoms or red flags occur, further diagnoses in the context of acute cough such as community-acquired pneumonia, influenza disease and exacerbations of chronic respiratory diseases (bronchial asthma, COPD) should be taken into consideration.

These evidence-based recommendations are intended to reduce the use of antibiotics to treat colds and acute bronchitis, for which they are not indicated. Further clinical trials of symptomatic treatments for cough should be performed in order to extend the evidence base.
