Current and Potential Uses for Wearables Within Chronic Disease Management in Clinical and Research Settings

Domain	Current and potential uses
Epidemiological	Monitoring and assessing physical activity Real-time, continuous assessment of PA over long periods of time, in large samples. Observe natural changes in PA through the disease course. Understanding context and correlates of PA Understand who is more or less likely to be physically activity in different contexts. Better understand PA preferences, frequency, intensity and duration in different contexts. Aggregated with other data sources to understand predictors and outcomes of activity behavior. Understanding individual disease trajectories Understand how activity patterns change pre-diagnosis, and as a result of different treatments or disease progression. Provide insight into disease progression. Identify potentially more effective timing, targets and subgroups for intervention. Understand whether predictors and outcomes of PA vary by patient or disease characteristics. Aggregate wearable data with other data sources to develop models to predict outcomes of interest (e.g., adverse events, disease progression, and functional decline). Data could be used as a proxy of overall health status to help inform clinical treatment decision making.
Health promotion	Given to patients or research participants as tool to facilitate PA behavior change and/or maintenance. Given to patients or research participants in combination with other intervention or program components to facilitate PA behavior change and/or maintenance. Combine data with data from other sources (i.e., sensor, patient reported outcome, clinical) to better time, target and tailor PA promotion interventions or programs.
