Adherence and health behaviours, can wearables help? 

Continuous monitoring like never before

The growing connectivity in the world provides a substantial potential of digital innovations for management of various diseases – including asthma1. However, this global digitalization is not reflected in routine care, because of multiple barriers, resulting in underutilization of digital technologies in health care2. Today, a large proportion of the world’s population own a smartwatch or fitness bands, which provides the potential for continuous monitoring of digital biomarkers and providing valuable insights that may enhance clinical decision-making. 

What are digital biomarkers?

A digital biomarker is defined as an objective parameter and indicator of normal biological, and pathological processes obtained by a digital device such as smartwatches or fitness bands. It could capture behavioral and physiological data, for example heart rate, physical activity and step counts.

Predicting exacerbationpossible clues

Various applications of digital biomarkers in asthma management have been investigated, including monitoring treatment efficacy, patient stratification, and shared decision-making3. In asthma, prediction of exacerbations would be crucial for patient outcomes and digital interventions can make a significant impact by providing early warning signs and improving patient awareness. For example, have changes in activity levels4, heart rate5, nocturnal cough6, and sleep quality6 been shown to be predictors of future exacerbations. However, clinical trials and real-world evidence of the potential of digital biomarkers is needed to leverage digital technologies transformation in asthma care on a strong scientific foundation.    

Making best use of digital biomarkers

In conclusion, integrating digital health technologies into asthma management to enhance patient monitoring, predict exacerbations, and improve outcomes have great potential. But stronger evidence of efficacy and effectiveness is needed to facilitate a broader discussion on how digital innovations can shape the future of asthma care.
