The Hailie™ solution (previously known as SmartInhaler™ platform) is a system of medication sensors (e.g., SmartTrack™, SmartTouch™, SmartTouch AV™, SmartTurbo™; http://www.smartinhaler.com/devices/) that wrap around existing inhalers and automatically sends usage data to a patient’s smartphone [34]. The sensors record the date and time of actuations, the total number of actuations used, and missed doses. The device pairs with the Hailie™ App and enables the patient and healthcare professionals to track medication adherence, set daily reminders, and discover insights into their medication usage. The SmartInhaler™ sensors have been studied extensively and have demonstrated high user acceptability as well as efficacy in increasing medication adherence [35, 36]. Five randomized controlled trials using the SmartInhaler™ have been conducted in the UK, Australia, and New Zealand, including a total of 589 adults and children with asthma in a community setting [35–39]. The authors of these studies conclude that SmartInhaler™ devices were more effective than standard care in improving adherence to asthma medication. Two of the studies showed significant improvement in clinical outcomes (e.g., asthma exacerbations, asthma control, and healthcare utilization) [37, 38].
