Brief Summary
The goal of this pilot randomized controlled trial is to assess the impact of D2D rideshare services with a trained companion driver on the rate of medical appointments for older adults and individuals with AD/ADRD. Participants will be assigned either door-through-door (D2D) rideshare or curb-to-curb (C2C) rideshare services. he main question it aims to answer is: Do D2D rideshare services reduce missed medical appointment rates compared to C2C rideshare services?

ACTIVE COMPARATORControl Group (C2C): Standard Curb-to-Curb rideshare services.
Interventions
Door-through-Door Companion Drivers, unlike traditional rideshare services, are certified in CPR and first aid, and undergo onboard training to support older adults, individuals with mobility impairments, and those with AD/ADRD. They are trained to observe behaviors of AD/ADRD patients, monitor and detect risk of falls, elopement, and other events that may require extra assistance or emergency care during transport. Drivers accompany riders continuously until they can hand off riders to clinicians or other caregivers, or return them to their home. Technology features in the rideshare platform enable continuity of care, for consistent rider-driver matching and matching of riders to drivers based on support needs.
Curb to curb rideshare services provided by a transportation network company (TNC) with drivers who don't have specialized training in supporting healthcare riders and who don't undergo fingerprint background checks or drug and alcohol testing.
