Road ahead to respiratory health: experts chart future research directions.

Respiratory illnesses are a huge and rising burden to health-care systems and societies worldwide. Research is crucial to tackle the enormous problem of chest diseases. However the vast number of research questions and available research approaches often creates confusion and risks dilution of resources by spreading them too diffusely. Clear research directions will help to use research funds efficiently to provide treatment advances that benefit patient care. This paper presents the visions of leading experts on future research directions, focusing on what should rather than what is going to be done. These opinions provide a guide for new investigators and a platform for intellectual debates through which coordinated research efforts can help progress towards respiratory health.
