[Digital tools for remote monitoring of asthma patients: Gadgets or revolution?]

Mobile applications, connected spirometers, connected inhalers, connected bracelets, connected watches, connected stethoscopes, connected air quality sensors ; digital tools in asthma treatment and management are on the upswing. They enable the functioning of advanced remote monitoring systems, combining continuous data collection from the patient's home and early intervention by health professionals. The first part of this review details the theoretical arguments in favour of using these digital tools for remote monitoring of asthma patients. In the second part, the different types of digital tools developed for asthma cases are described and illustrated with examples. The third part presents the results of randomised trials comparing remote monitoring systems incorporating digital tools with more traditional management. Limitations to the use of digital tools in such systems are discussed in the fourth section. Finally, the fifth part presents perspectives for digital ecosystems in asthma and the possibility of obtaining autonomous algorithmic decision-making systems for individualized adaptation of patient management.
