Introduction: Wearable devices such as smartwatches and fitness trackers are widely used. While marketed to consumers for general wellness, many devices measure physiologic parameters with implications for cardiovascular health. The prevalence of wearable device use in contemporary patient populations is unknown. We sought to 1) determine characteristics of current and prospective device users within a large healthcare system and 2) assess user interest in incorporating device data into the electronic health record for clinical research purposes.Methods: Participants were selected from a database of adults aged ≥ 18 years who received longitudinal primary or cardiac care at one of 11 hospitals within the Mass General Brigham network between 1/2010 and 7/2021. We identified living patients with an active electronic portal account for direct communication. Portal users were invited to complete a survey about use and medical applications of wearable devices. Multivariable logistic regression was used to identify factors associated with device use.Results: Between 11/2021 and 4/2022, 214,935 patients were contacted with 10,947 (5%) unique survey respondents. Rates of device use were similar among primary care (56%, n=4,739) and cardiology (53%, n=2,190) patients. Almost all non-users (97%, n=4,540) reported that they would use a device if not for cost. In a multivariable model, factors associated with device use included: age (odds ratio [OR] per 5-year increase 0.89, 95% CI [0.87,0.90]), female sex (1.19 [1.09, 1.29]), cardiac vs primary care (1.27 [1.16, 1.39]), median household income by zip code (OR per 1-standard deviation increase 1.10 [1.06, 1.15]), and better self-reported health (OR for “excellent” vs “poor” health 3.35 [2.27, 4.99]). Almost all users and potential users (96%, n=9,811) would share device data with researchers studying health outcomes.Conclusion: Among survey respondents, younger age, female sex, cardiac care, higher income, and better self-reported health were associated with wearable device use. Current and prospective device users are interested in sharing longitudinal data, which will enable further study of wearable devices and their role in care delivery, clinical outcomes, and health disparities.
