NCT06850870 · Phase 1 · RECRUITING

Door-Through-Door Companion Rideshare Technology for Individuals With Alzheimer's Disease and Related Dementias (AD/ADRD)

This pilot trial compares two types of rideshare services for older adults with memory problems or dementia: a door-through-door service with a trained companion driver versus a standard curb-to-curb rideshare. The main question is whether the companion model reduces missed medical appointments. This is a Phase 1 pilot, meaning researchers are testing feasibility and early results, not a proven or approved intervention.

You may qualify if

  • All participants (or their surrogate) have the capacity to agree to allow Onward service for transportation;
  • have scheduled medical appointments at partner practices of Onward;
  • ages 60+
  • community-dwelling;
  • 60 participants who self-reported cognitive problems, such as memory issue, or have mild cognitive impairment, subjective cognitive decline, or AD/ADRD diagnosis
  • Resides and attends appointments in the following San Francisco Bay Area Counties (San Francisco, Alameda, Contra Costa, Marin, San Mateo, Sonoma)

You're excluded if

  • current enrollment in another transportation study;
  • already using any type of free or heavily subsized transportation service;
  • enrollees with comfort care only;
  • Not wheelchair bound, e.g. if using a wheelchair must be foldable and must be able to transfer
  • Transient, lacking consistent long term housing
  • Resides outside of the San Francisco Bay Area
