Use of antibiotics in patients admitted to the hospital due to acute exacerbation of chronic obstructive pulmonary disease (COPD).
BACKGROUND: The purpose of this study was to assess to what extent symptoms and signs of bacterial infection are present and evaluated in patients admitted to the hospital for exacerbation of chronic obstructive pulmonary disease (COPD) in relation to initiation of antibiotic treatment. METHODS: All adult patients (>18 years of age) discharged from a department of internal medicine in Copenhagen in 1997 with a diagnosis of exacerbation of COPD were included in our study and their reports were retrospectively reviewed. Gender, age, number of admissions and length of hospital stay, use of antibiotics and steroids prior to admission, temperature, white blood cell (WBC) count, results of lung auscultation and X-ray examination of the thorax at admittance, and growth of sputum culture and antibiotic treatment in the hospital were all registered. RESULTS: A total of 400 admissions took place. In 104 of them, chest X-ray was compatible with pneumonia, and 99 cases were treated with antibiotics. In 44% of the remaining 296 cases, antibiotics were given. It was found that 25-45% of the patients with very little evidence of infection-i.e. the absence of, or only the presence of, one of the following indicators of infection: fever (temperature>37.5 degrees C), a raised WBC count (>9 billion/l), or crepitation at lung auscultation-were given antibiotics. In cases presenting with two or three of these indicators, 50-75% were given antibiotics. In 85% of the cases, penicillin or a macrolide was the initial antibiotic of choice. The median hospital stay was 6 days for the entire group of patients. CONCLUSION: These data suggest that, in patients with acute exacerbation of COPD, a relatively high number of patients with only weak symptoms or signs of bacterial infection are treated with antibiotics.
