Objective: To characterize trends in device usage (mobile-device vs. personal computer (PC)) across demographic factors for video-based telemedicine visits in an urban tertiary Movement Disorders clinic in the U.S.

Background: The rise of telemedicine during the COVID-19 pandemic has improved healthcare access, but data on device usage and disparities in telemedicine access remains limited. We hypothesized high mobile-device usage and ubiquity of telemedicine utilization across diverse demographic groups.

Method: We conducted a retrospective chart review of all televisits with Movement Disorders neurologists at Rush University from March 2020 to March 2023, analyzing visit-specific data embedded within the electronic medical record.  We analyzed variations in device usage patterns across different age groups (<60, ≥60), sex, race, and socioeconomic status (zip code median income). Televisits were categorized into mobile (smartphones and tablets) or PC-only. Chi-square tests examined the device usage distribution, with effect sizes calculated to assess the strength of differences. Logistic regression analyzed the odds of mobile-only usage.

Results: We identified 2,181 unique patient televisits. 87.8% of televisits were accessed with mobile-devices.  The mean age of mobile users was slightly lower at 62.1 vs. 64.9 years in PC-users (p=0.02).  The Chi-Square analysis revealed statistically significant but clinically insignificant results due to small effect sizes (both 0.07): younger patients (<20) showed the highest mobile use (p=0.03) and the lowest income quintile had 100% mobile usage while the highest quintile had the lowest (p=0.03). Logistic regression revealed no significant predictors of mobile usage.

Conclusion: Mobile-device use for telemedicine in Movement Disorders is widespread across all demographics. These findings emphasize the role smartphones play in facilitating access to telemedicine, suggesting that enhancing mobile-based telemedicine applications could improve healthcare equity particularly for vulnerable populations.
