[Asthma guidelines: knowledge of family doctors and trainees in Germany]

In Germany as well as internationally, evidence-based asthma guidelines were developed as a decision aid for diagnosis and therapy. However, adherence to recommendations is usually less than optimal. The authors explore potential implementation barriers: knowledge gaps, practical presentation of guidelines, and attitudes of doctors and patients. In this paper, we compare results of our knowledge survey of family doctors and trainees with results of similar national and international studies. In all studies, all surveyed groups of physicians revealed considerable knowledge gaps. Many physicians in our own study erroneously preferred mucolytics and antibiotics to treat acute or subacute asthma symptoms though these drugs are not or only exceptionally indicated. The inflammatory character of asthma often goes unrecognized, as well as the importance of inhaled (and systemic) corticosteroids in long term treatment (or treatment of exacerbations).
