Teacher: Now, understand the problem? Solve this instance: Question: Do location and duration of treatment of cystic fibrosis respiratory exacerbations affect outcomes?
Answer: Intravenous antibiotic therapy for CF respiratory exacerbations administered in the hospital and in the home was found to be equivalent in terms of long-term FEV change and interval between courses of antibiotics. Optimal duration of therapy (7-10 d) may be shorter than current practice. Large prospective studies are needed to answer these essential questions for CF respiratory management.
