Secondary outcomes include the time of arrival to the clinics relative to actual appointment time (both arms), prospective utilization of acute care settings (both arms), prospective utilization of primary care (both arms), and description of programmatic metrics in the intervention arm (travel time, misuse, and costs). The investigators will assess the patient experience after each ride using a telephone-based survey and in-depth interviews. All adults with established primary care at the Penn Medicine Clinics, who have Medicaid, and do not require wheelchair accessible rides will be eligible for the rideshare service. The investigators hypothesize that individuals offered a rideshare-based transportation service will have a decreased proportion of missed appointments and same day cancellations as those not offered the service.
