Healthtech firms are building products that let people manage chronic conditions at home, and the barrier to uptake is rarely the device itself. What stalls adoption and adherence is human: routines that resist change, attention that fixes on immediate side effects rather than distant benefits, communication that leaves patients unconvinced, and interfaces that invite error from users who were never trained as clinicians. This report explains why those barriers arise and what can be done about them. From there, practical interventions drawn from academic research and existing products, and a checklist for design and marketing teams.
