Antibiotics are overprescribed in asthma-related hospitalizations, even though guidelines recommend against prescribing antibiotics during exacerbations of asthma in the absence of concurrent infection, reported Peter K. Lindenauer, MD, MSc, of Baystate Medical Center in Springfield, Mass., and his colleagues.
They examined the hospitalization records of 51,951 individuals admitted to 577 hospitals in the United States between 2013 and 2014 with a principal diagnosis of either asthma or acute respiratory failure combined with asthma as a secondary diagnosis. Each patient type and the timing of antibiotic therapy was noted.
A total of 30,226 of the 51,951 patients (58.2%) were prescribed antibiotics at some point during their hospitalization, while 21,248 (40.9%) were prescribed antibiotics on the first day of hospitalization, without “documentation of an indication for antibiotic therapy.”
Macrolides were most commonly prescribed, given to 9,633 (18.5%) of patients, followed by quinolones (8,632, 16.1%), third-generation cephalosporins (4,420, 8.5%), and tetracyclines (1,858, 3.6%). After adjustment for risk variables, chronic obstructive asthma hospitalizations were found to be those most highly associated with receiving antibiotics (odds ratio 1.6, 95% confidence interval 1.5-1.7).
“Possible explanations for this high rate of potentially inappropriate treatment include the challenge of differentiating bacterial from nonbacterial infections, distinguishing asthma from chronic obstructive pulmonary disease in the acute care setting, and gaps in knowledge about the benefits of antibiotic therapy,” the authors posited, adding that these findings “suggest a significant opportunity to improve patient safety, reduce the spread of resistance, and lower spending through greater adherence to guideline recommendations.”
The National Heart, Lung, and Blood Institute and Veterans Affairs Health Services Research and Development funded the study. Dr. Lindenauer and his coauthors did not report any relevant financial disclosures.
