American Thoracic Society Journal news tips for November 2003 (first issue)

An asthma intervention study showed a 60% reduction in total hospitalizations among patients with frequent asthma exacerbations. Researchers also found that initial use of three antibiotics followed by diagnostic testing led to better patient survival and reduced antibiotic use for ventilator-associated pneumonia. Additionally, prematu...
