title: Historical cohort evaluation of ribavirin efficacy in respiratory syncytial virus infection.
abstract: Evaluation of ribavirin therapy for respiratory syncytial virus infection of the lower respiratory tract is problematic because of multiple risk factors and variable severity of illness in respiratory syncytial virus-infected patients. To address these difficulties we used multivariate analysis and performed a historical concurrent cohort study in two children's hospitals one of which had used ribavirin since licensing and one that had not utilized ribavirin therapy. The medical records of 158 patients who satisfied the American Academy of Pediatrics inclusion criteria for receiving ribavirin were analyzed for three seasons (1988 to 1991). No significant benefit of ribavirin therapy could be appreciated for the whole group in length of stay (median, 5.0 vs. 6.5 days), days on oxygen therapy (median, 5 vs. 3), progression to ventilator status (3.8 vs. 3.9%) or mortality (1.9% vs. 1.9%) for ribavirin treatment vs. supportive care. Multivariate analysis failed to uncover a beneficial effect of ribavirin when all risk factors were considered. No significant differences were noted when ventilated and nonventilated patients were examined separately. Our data raise questions about the efficacy of ribavirin when used in common practice and suggest that further prospective study, with appropriate analysis, is needed to justify the continued widespread use of this drug.
