The improvement of asthma-related quality-of-life represents an important goal for the overall pharmacological management of asthma. Juniper has developed and validated questionnaires for the measurement of asthma-related quality-of-life and asthma control in both children and adults. Furthermore, Juniper has defined the minimum improvement in asthma-related quality-of-life that is clinically relevant for participants with this disease. In addition, Juniper has recently validated on-line versions of the asthma-related quality-of-life and asthma control questionnaires in children aged 12 and above. This could provide an opportunity for more long-term and cost-effective comparisons of different asthma treatments through the use of tools that measure asthma control without the need for clinic visits and the completion of paper-based forms.
