Adapting Facebook-Style Features for Disease Prevention in Clinical Care

Building on previous work, we posed a practical challenge: can we bridge the silo between social-media engagement and clinical care without importing platform risks? We present a minimal viable design for a Canadian primary care intervention that adapts familiar social media features and aligns them to Self-Determination Theory (SDT). Feeds support autonomy with user-controlled topics, pacing, and plain-language "why you saw this" rationales. Timelines support competence through short lessons, tiny practice steps, light data entry, and brief coach feedback. Groups support relatedness via moderated, goal-aligned peer exchanges. At population scale, a predictive service classifies patients as at-risk for diabetes within an 8-year horizon. Clinicians then enroll eligible patients by placing a preventive-care prescription in the electronic record. Clinicians receive a monthly patient population-level report that lists actionable cohorts, aggregate SDT signals, safety metrics, and equity views. The existing literature supports mapping of social-media features to health apps and several authors have successfully implemented these features in various clinical settings. To adapt these insights for the Canadian context, we consulted a variety of stakeholders (N=13) who validated and refined the design and produced measurable acceptance criteria for implementation. These included managing privacy and governance, misinformation controls, engagement ethics, platform independence, peer matching, prediction, and reporting. Next steps are architecture finalization, broader co-design, and a single-system feasibility pilot.
