Guidelines versus clinical practice in antimicrobial therapy for COPD.
Limited information is available about current practice patterns involving the use of antibiotics in the inpatient management of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). We sought to characterize current patterns of antibiotic use and to compare them to evidence-based guidelines. This study is a retrospective case series of patients at a regional tertiary care medical center. Charts were reviewed to identify patients admitted between January 2006 and 2008 with an initial diagnosis of AECOPD who had no evidence of another infectious process and who were not immunocompromised. Relevant data extracted from charts included initial clinical presentation, antibiotic administration, microbiological studies, and hospital course. One hundred sixteen admissions meeting inclusion criteria were identified. There was no statistically significant relationship between the presence of an established indication for antibiotic administration and the use of antibiotics, with roughly 75% of patients in all groups receiving therapy. A significant fraction of patients received combination therapy that was more appropriate for the management of pneumonia than for AECOPD. There were significant deviations between practice patterns and guidelines regarding the use and selection of antibiotics. Some of these may reflect areas of uncertainty in the primary literature and varying sets of guidelines.
