Question 16 of 20 · Change and evidence
Prevention, wearables and continuous medicine
Will constant monitoring keep people well, or just keep them worried?
1 min read · Partly measured today
Episodic clinic visits give an incomplete picture of health. Continuous data could change that, and could also add false alarms, anxiety and unnecessary care.
What we can measure today
- Emerging
In a randomized trial of 150 diabetes patients using a digital twin program, 71% reached healthy blood sugar levels over one year while safely reducing medications.
What this does not prove: One small trial of one product in one condition.
Stanford HAI, 2026
The 2026 AI Index Report, Chapter 6: Medicine
Scope: Global research, with U.S. data on FDA authorizations.
How it was done: An annual review that summarizes studies by other researchers.
Limits: A summary of studies with different designs. Each headline figure comes from one setup and does not generalize on its own.

FDA authorized IDx-DR in 2018 to automatically detect more than mild diabetic retinopathy in primary care, finding 173 of 198 cases and correctly clearing 556 of 621 people without it.
What this does not prove: One disease and one camera. It screens and refers.
U.S. Food and Drug Administration, April 11, 2018
De Novo DEN180001: IDx-DR
Scope: U.S. adults with diabetes and no prior diagnosis of retinopathy, at 10 primary care sites, 819 fully analyzable.
How it was done: FDA's review of a pivotal study of automatic detection using one camera model.
Limits: Screens for one eye disease and refers. It does not treat, and FDA says physicians should review results and advise on referral.

We have not yet verified broad evidence on whether wearables improve hard outcomes.
What may change
- Continuous sensing and early warnings.
- At-home diagnostics, personalized prevention and virtual care.
What may endure
- False positives, privacy, uneven access and patient preferences all stay relevant.
The hard questions
- Will more monitoring improve outcomes, or create anxiety and unnecessary care?
Evidence worth watching
Trials of hard outcomes · False alarm burden · Payer coverage · Accessibility
