Put Sensors for Inhalers in Perspective
"Smart inhaler" technology (Hailie, Propeller, ProAir Digihaler, etc) for managing asthma or COPD is creating a stir.
These inhalers use sensors to record when doses are delivered. The idea is to track inhaler use...and boost adherence to controller meds.
But there's no proof they reduce ED visits or hospitalizations...and they often have added costs.
