Digital Recruitment Reveals Socioeconomic Participation Disparities

Mayo Clinic researchers conducted a longitudinal remote speech study using patient-portal invitations from March–July 2024, tracking 5,846 invitees; 415 (7.1%) completed all tasks. They found completers were older (median 66.4 vs 62.8 years; P<.001), higher neighborhood disadvantage associated with lower response (ADI differences, P<.001), and urban participants enrolled faster than rural (median 32 vs 41 days; P=.01), leading to calls for multichannel, age-specific, and rural technical outreach.
