Guidelines for managing community acquired pneumonia in adults

Many recommendations remain based on the lowest grades of evidence

New guidelines from the British Thoracic Society for managing community acquired pneumonia in adults were published in December 2001 in Thorax.1 They have been formulated using modern methods with explicit search strategies and appraisal criteria. Recommendations are graded according to the strength of the supporting evidence. They cover the assessment and management of pneumonia in the community as well as in hospital.

The one community based study from the United Kingdom cited here found S pneumoniae in 36% of patients and atypical pathogens in about only 1%.2 This study, however, dates from 1987 and more recent studies from the rest of …
