Abstract
The objective of this report was to document the pattern of initial antibiotic prescribing in acute exacerbations of chronic obstructive pulmonary disease (COPD) in a hospital setting. All episodes of acute exacerbation of COPD, as diagnosed by the admitting doctor, in one hospital in the period January to May 1996, were identified. Case notes were reviewed retrospectively. Cases of radiographic pneumonia, bronchiectasis and incorrectly coded admissions were excluded. Symptoms, microbial cultures and initial antibiotic therapies were recorded. One hundred and fifty-nine patient episodes were identified; 40 were excluded yielding a sample of 119. Nineteen case notes were unavailable leaving a sample of 100 (84%) episodes. Eighty were treated with antibiotics on admission; amoxycillin was the most frequently prescribed, in 46 (58%) episodes. Of the antibiotic treated group, 42 (53%) patients were given dual therapy, most commonly a macrolide antibiotic with either amoxycillin or a cephalosporin. Intravenous treatment was used in 22 (28%) cases. The duration of intravenous treatment was >48 h in 12 (15%) cases. A total of 76 sputum samples were analysed from 55 patient episodes: 34 (45%) were culture positive. In 15 (27%) patient episodes, antibiotic therapy was changed or instituted on the basis of culture results. These data suggest that antibiotic treatment is not optimal, with overuse of antibiotics, especially intravenous and dual therapy.
