Abstract
A prospective survey involving a group of 95 general practitioners (GPs) in France was conducted to describe antibiotic therapy prescribed for out-patients with community-acquired pneumonia (CAP). A total of 173 cases of CAP, defined by the association of fever and pulmonary focal crackles and/or radiological changes consistent with a pulmonary infection, were reported between February 1993 and March 1994: 84 males and 89 females (mean age: 48 yrs) of whom 45% had no underlying disease. Nineteen (11%) were immediately hospitalized and the remaining 154 out-patients were treated without microbiological investigation. First-line antibiotic therapy was amoxicillin or amoxicillin-clavulanic acid combination (57%), a first or second generation cephalosporin (12%), ceftriaxone (8%), oral broad-spectrum cephalosporin (3%), a macrolide (16%), a tetracycline (1%) and a fluoroquinolone (2%). A total of 120 (78%) patients recovered with no change in treatment and 34 (22%) patients failed to improve: 18 were hospitalized and 16 had a second-line therapy, mainly a macrolide or a quinolone. Five patients died at hospital. The overall mortality was 3%, and 14% in hospitalized patients. Empirical therapy using a betalactam to target a presumed pneumococcal infection, in agreement with European guidelines, is appropriate for out-patients with mild lobar community-acquired pneumonia.
