Abstract
This protocol describes FRESH AIR, an implementation science project exploring how to improve the prevention, diagnosis and treatment of chronic lung diseases in contexts with limited healthcare resources. It consists of inter-related studies that take place in four countries that are part of the International Primary Care Respiratory Group's (IPCRG) global network: Uganda, the Kyrgyz Republic, Vietnam and Greece. The project has been funded by the European Commission Horizon 2020 research programme and runs from October 2015 until September 2018.
