The study showed that connected inhalers, which use Bluetooth sensors that attach to participants' asthma inhalers to detect medication use and share the data with physicians, may promote adherence to recommended controller medication use and proactively detect worsening of asthma symptoms.; "Emerging connected technologies can help improve patient health, with this randomised-controlled clinical trial showing that pediatric asthma patients with access to inhaler sensors report better asthma control and quality of life than patients who only received a standardized asthma education curriculum," said lead author Ruchi Gupta from Northwestern University.
