Digitally mapping the asthma journey-from diagnosis to remission

Digital technologies can play a central role in achieving precision medicine by monitoring changes in physiological and behavioural states. This could transform asthma care for the health provider and patient across the patient journey, from diagnosis to remission. For diagnosis, smartphones and artificial-intelligence-enabled devices can objectively capture respiratory symptoms, while digital peak flow meters enable home assessment of airflow variability. For routine monitoring and self-management, technologies can monitor biomarkers more frequently, digital inhalers can improve medication adherence and control whilst serious games can improve patient knowledge. Symptom tracking, lung function monitoring and environmental parameters can help identify exacerbation triggers. For assessing remission, digital technologies can capture most of the components of remission definitions, from exacerbations to reliever use, enabling a more objective assessment of this emerging endpoint. Together, this evidence supports the role of digital technologies in enabling the personalised approach to asthma called for by the Lancet Commission.
