Current progress and boundaries
Health apps and wearables can flag trends, but data quality varies across devices and long-term adherence often declines.
Why it remains difficult
Sleep, diet, medication, and social support affect one another. A model must distinguish measurement error and temporary fluctuations from genuine changes in risk, while accounting for whether patients can follow the advice.
Paths worth exploring
Begin with one condition and a clearly defined care pathway. Limit recommendations to reviewed protocols, and design patient confirmation, care-team review, and escalation for unusual cases.
How to evaluate success
Track follow-up completion, alert accuracy, the share escalated to people, and patient burden. Assess health outcomes over an appropriate period rather than relying on click-through rates.
