[Management of bronchial infectious episodes in general medicine]

Acute bronchitis and chronic obstructive pulmonary disease exacerbations are frequent reasons for consultation with a general practitioner (GP). Since no consensus exists about the use of antibiotics in such indications and little is known about the use of pulmonary function tests in general practice, our objective was to describe GP's attitudes and prescription habits when faced with patients suffering from acute bronchitis (AB) or chronic bronchitis (CB) exacerbation.

The GPs participating in public health surveillance through the "réseau Sentinelles" (French Communicable Diseases Network) in March 1993 answered a postal questionnaire. This questionnaire collected their clinical attitude and prescriptions for 7 clinical cases of varying severity.

430 (94.7%) of the GPs answered the questionnaire. Of these more than 95% prescribed antibiotics in all the clinical cases, including for common acute bronchitis. Wide spectrum penicillins and macrolides were prescribed significantly less often as the past history increased in severity, whereas tetracyclins and oral cephalosporins were prescribed significantly more often in severe cases. Fluoroquinolones were nearly exclusively reserved for the treatment of advanced CB. Smoking cessation was systematically advised by the GPs. Faced with AB and a smoking history, 44.2% of the GPs prescribed a chest x-ray. In the case of repeat episodes of winter bronchitis, more than 70% of them evoked the diagnosis of CB. 98.% of the GPs had easy access to pulmonary function tests (PFTs) which 69.2% of the GPs prescribed as soon as CB was suspected.

In the absence of a therapeutical consensus regarding bronchitis, antibiotics were prescribed virtually systematically. PFTs were not yet a routine gesture in general practice even though they were widely available and prescribed.
