ABSTRACT
Selecting the optimum delivery system is essential to ensure patients gain maximum benefit from inhaled therapies. The selection process must take account of device attributes, including size, type of inspiratory maneuver required, carbon footprint, ease of use, smart features, and cost. It must also take account of patient factors, including their cognitive ability, manual dexterity, coordination, and ability to perform correct inspiratory maneuver, as well as clinician factors. If a patient is currently taking inhaled therapy and able to use their current device correctly, new therapy is best prescribed in the same device. If a new device is required, either because the patient is not using their current device correctly or the drug is not available in the same device, a systematic iterative process should be used to select a delivery system and ensure the patient can use it.
