Our proposal will scale up and evaluate MOvIT+ (Mobility Outcomes via Information Technology), a web-based service that is unique and novel in Canada. Technology: MOvIT+ brings together multiple digital technologies to enhance the follow-up of older adults and caregivers who use mobility assistive technologies (ATs): i) an Internet-based system for registration, telemonitoring and teletraining after prescription, ii) a sensor-based intelligent positioning system to monitor the actual usage of the mobility device and provide feedback based on clinical recommendations, iii) a website that regroups training resources for mobility AT users. The current proposal will be adding iv) a dashboard for decision makers at the local and provincial levels, vi) a 3D mapping application of the user environment, vii) a Cloud infrastructure to manage the anonymized sensor-based data generated by the fleet of instrumented devices. Services: MOvIT+ helps structure the follow-up services that are otherwise not available in the healthcare system. It offers training tools based on the monitoring results and alerts rehabilitation professionals only if remote counselling of the user/caregiver is needed. Policy & Practices: A large-scale implementation protocol will be co-developed with participating sites and our advisory committee for multiple target audiences: AT users, caregivers, clinical teams, community partners, funding agencies, and technological partners. The Quebec Ministry of Health supports our proposal as this will be the first Canadian initiative providing large-scale ongoing monitoring of the clinical impacts of mobility AT funding programs. We are partnering with CEFRIO, a non-profit organization that specializes in the implementation of innovations in organizations, to study and support our implementation process. This will broaden MOvIT+ (refinement and validation of current components, integration of new digital components, specification requirements for scaling up to new sites) and scale it up for dissemination in 7 Canadian sites, reaching >1000 AT users.
