Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary clinical outcome measure will be the difference in the percentage of positive isolates of pseudomonas aeruginosa obtained as part of routine clinical care during the 3 year study period between children receiving oral ciproxin or placebo for treatment of acute respiratory infections. ;Secondary Objective: Secondary outcome measures will include: 1. Time to first detection of pseudomonas at routine 2 monthly clinic visits using both conventional and molecular biological specimens. 2. Numbers of P. aeruginosa detected by conventional and molecular biological testing at 2 weeks after taking study medication. 3. Number of infective exacerbations needing hospital admission/intravenous treatment 4. Cost benefit analysis of health care resource utilisation as a result of the use of ciprofloxacin 5. Difference in symptom diary recording of lower respiratory symptoms. 6. Conventional and molecular microbiological data will also be explored to determine the relationship between specific viral infections and the occurrence of P. aeruginosa at the time of acute viral infection. 7. Differences in serum ELISA assays for pseudomonas between the beginning and end of the study ;Primary end point(s): The primary end point will be between group differences in the percentage of positive isolates of P. aeruginosa at routine clinic visits. Secondary endpoints will explore differences in symptoms and the need for additional therapy | — |
